I saw one of your vids some time ago, then the CZcams algorithm seemed to not recommend them. I couldn't find the one I saw in my history. Anyway that aside, glad I found this video and thought it was a great explanation of SAS and also storage in general. I also have what you might call a storage focus, I love adding and modifying arrays to see what they can (or can't) do. Although I've only ever used two brands, HP/Compaq and NetApp.
Great video 👌
Thanks!
Dell servers are also good to work with in the future... Refer to my video on the DX series. Great chassis for storage work.
Legend! Thank you sir! Glad I found this.
GREAT explanation of that unit. TY!!
Great clip... I got EVEY information that I looking for!!! 😀
Great break down thank you.
Glad it was helpful!
Gotta say...... You really know ya 3PAR
Thanks much for the video explaining both the M6710 and multipath SAS. I've managed to get my drives to show up on a Smart Array P822. First I had to turn on HBA mode to reformat my drives from 520 sectors to 512. I needed to unplug 1 controller from the enclosure for my drives to show up. If I connected both, the pathing would not be recognized and 48 drives would show up. Using only 1 path and 1 controller seems to do the trick.
However, unfortunately ALL bay IDs are reporting Unknown. This makes addressing the physical drives quite difficult in ssacli. The SSA UI utility allows me to create the Logical Drive, though. Would love to hear if anyone has a solution for that one (or how I could get dual paths working properly without my LD disappearing and PDs duplicating)
Thanks for your overview it is very well presented. I have a lot of experience with HPE servers but Zero with 3PAR storage. I have obtained a few of the Disk enclosures complete with genuine 3PAR 2.5" SAS drives but without the 3 PAR controller head unit. Having seen your video, I was keen to get them set up and learn more. However, I am not having any success in connecting to HP DL380 Gen7 - 8 or 9 servers and have tried a variety of SAS controllers including P222 & P822 with what I believe are good quality cables. Despite anything I tried, the onboard HP Smart Array controller doesn't see the external array or even the individual disks. I am wondering if there are specific cables required or tweaks required and would be very grateful if you could provide any pointers to known working combinations of Array controllers and Cables or any particular issues you know which fail connections . I have connected other MSA disk arrays to these servers successfully. Sorry for the public posting as I could not see a private message button
Try doing just one cable test the drive path way. I use the LSI controllers. If you use both hook up. That will give issue unless you build out a dual pathway controller configuration using HPE SAS controllers
So much of this video bothers me.
1. It's called "Daisy Chaining", not "the Passthru".
2. The 3PAR 7000 series pictured was SAS, there was never a SATA option. SATA is not really appropriate for the reliability and uptime for Enterprise Storage.
3. All 3PAR systems are Fiber Channel or iSCSI connected from the main controller. They are a completely different thing from a MSA. Comparing a 3PAR to an MSA is like comparing the Space Shuttle to a private Jet.
3. A HBA is not a SCSI Controller, a HBA is a way of connecting a host (server) to SAN Storage. Basically a HBA is Network card for storage networks. (SANs).
Hey I have another question, if I was to use a older machine with a RAID card already built in, is there any value loading FreeNAS? or TrueNAS? My goal is to use the machine for storage, files, videos, maybe a VM or two. What are your thoughts? OR is it better to replace the RAID card with HBA card?
I would try FreeNAS / TrueNAS. The OS can add some benefits using the motherboard RAM. If you have some...
What's the maximum per disk supported by this model ? 8TiB ?
I had a need for an external enclosure for my homelab. I found a used one of these online and decided to try it. I found your video when I was trying to figure out how to cable it to my server. It came with two cables. My first attempt was to connect each of the two external ports on my LSI SAS9207-8E to a DP-1 port on the M6710. This worked and my server was happy with that arrangement. However, the fault light on the M6710 bezel is on and the fault light on each of my eight SATA drive trays is also on. All lights on the back of the M6710 are green, there are no yellow lights on the back side. When I first power up the enclosure, there are only green lights on the front. When I power up my server, the activity lights will flicker when the bios checks them out. Once Proxmox is loaded and running, the fault lights come on. I don't have any daughter cards for the SATA drives. They are plugged directly into the backplane. Is that the issue? Or is it something else?
I think your cable setup is wrong on the back of the unit. Your server will plug into Top A port on the back of M6710, then top port B goes to the lower A port and then the lower B port needs to go back to controller in your server. Do you have it setup that way? I bet you are only doing a single pathway currently and will create errors issues. Also you can just test the upper M6710 controller and then the lower controller part. Doing will allow you to test 12 drives at a time on each controller. Let me know what you find out...
I am working on that. I only have two cables at the moment. I have another one on order. My second attempt with two cables was one from server to DP-1 and the other from that DP-2 to the other DP-1. Server is still happy, but no change in M6710 lights.
@@tsimblist Yes but you need a cable going back to your server from the lower PS-2 port to provide you a redundant path instead single path. Server to top PD-1 - top DP-2 to lower DP-1 - Lower DP-2 back to server second port. That should work. /:>
I received the cable that I ordered and cabled up my server with the M6710 as you instructed. No change in symptoms. I'm afraid I may need the interposer cards for my SATA drives to keep the fault lights off.
No the array can do both SATA and SAS but try not to mix them on the same bus, Put SATA together on bays 0 thru 11 (Bus 1 and 2) and SAS on bay 12 to bay 23. (Bus 3 and 4) Run them in separate buses or they will fight with each other. Also boot into a basic Linux OS like Centos on a USB stick, (Like in my videos) instead of booting into a full blown Proxmox OS. Test at the core level away first and when all your issue/s are address then test your targeted OS. Step by step you will get it work. As for the yellow lights, I will research with my 6700 series 3PAR array and see what that issue is. I will get back to you on that one. The Yellow alert maybe a false / positive alert do to the heart beat JR-45 or serial connections connected. You don't need them when doing core SAS connectivity.
Thanks for this. I'm new to storage arrays; have some stupid questions. what kind of connector is that on the back of the i/o controller? different from stacking cable? ('cuz those seem expensive). doesn't look like sas port. what is it and where do we get cheap ones?
or is that just mini sas and there's something wrong with my eyes?
not sure, what is the make and model?
Hey, nice video thank you! just got a used M6710 and i just wonder what the button and the display do. With a long press on the button, i can change the number on the display between 1 and 24 but what is the usage for? Would be wonderfull if someone can share some knowledge with me about this, cant find any information online....
the display screen shows the order of which disk array is in order to the next disk array. You see when you buy a new HPe 3PAR storage array it will come with four to ten M6170 disk arrays. We hook them up one at a time and ID each disk array in order so you know what order they are hooked up. When the system reports a bad disk in a array, you just check the array ID then look at the display to find the right array and count the disk to the correct dying disk and replace it. Hope that helps some...
Good video, have been looking for info on options for routing SAS/8088 cables from a single server to a 3Par M6710.
So, I have such a disk cabinet with 24 10k 900 GB SAS drives.
I am in the process of changing them from 3Pars's 520 bit to 512 bit, so the disks will be usable from Linux/Win.
Weird thing is: If I have the first/leftmost disk (bay 0) inserted, the attached computer will not pass the initial "initializing" prompt during boot.
As soon as I eject that disk (and have all 23 other disks inserted) the initialise step is done in a few seconds and boot proceeds as normal.
Using a HP HBA 221 card in the computer, 2 8088 connectors on the back.
I have tested all (?) combinations of cabling from computer > disk cabinet (using one or the other connector on the 221 card and all combinations on the disk cabinet).
Same thing no matter what.
Any ideas?
Well I am thinking three things here. One, a post state BIOS level DIAG that is failing and stops the posting process. Two, a preset setting looking for a SSD type cache disk that never got cleared and slot 0 is the home for that SSD drive. Or three, You have a bad 0 bay slot. For issue one or two. swap out the HBA controller and use a cheap LSI series 9200 or 9300 HBA controller. (Your problem is fixed or at least IDed.) They have no post DIAG check or or caching options so the controler jsuts boots up, For problem three issue. Remove all the disks from the array. boot with only a clear empty array. Go into the BIOS of the HBA go to the disk util screen that shows what disks are available for use. Then add one 512 Sector formatted disk that you know is good and place it into the slot 0 bay slot and check the bios disk list to see if the newly added disk posts as a new available hot swap drive in slot 0 ready for use. If it doesn't come up then you most likely have a bad slot or a on board controller that is failing. If it does come up then an few more known good disk, one at at time to test the pairing bridge bus of the array to see if it can sync with other disks, if the disk goes away of not usable then you have a bad slot 0 bus connection. Hope this help you out...
@@leadiususa7394
Many thx for your feedback, much appreciated and useful to get thoughts started.
So... you're thinking the HBA card might have some old setting that's causing this?
Could be, but I have re-flashed/upgraded that card - still possible of course that settings have persisted.
Will try an 92xx card once I find a 8087>8088 cable.
I know way too little about the internal workings of these disk cabinets, how much smartness etc there is in them.
But I suspect it's not a whole lot, they are more like a fancy SAS fanout setup - and that the logic/smartness would reside in the 3Par controller node(s).
For example, I can't find any firmware updates to the M6710s, which could be due to them being old/proprietary or there isn't much in them to be updated.
But that's just me assuming stuff, really..
Another question:
You mentioned there are 3 channels in this box (8+8+8 disks).
That's pretty interesting and not very obvious from looking at it externally.. and would have an impact on how disks are allocated to a RAID array created on OS-level - right?
Let's say we'd like an as simple as possible RAID5 across three disks, then those three disks should be on separate channels to avoid traffic congestion. Or?
@@goransander4461 IT doesn't work that way. The bus channels are there for both bandwidth management and Bus speed control. Each channel can do the max of only, so if you put a SATA and a SAS disks in a a single bus, you only go the speed of the slowest drive. Als ot answer your question, for 24 bay drive arrays, it is as follows: 1-7 channel 1, 8 to 15 is channel 2 and 16 to 24 is channel 3. Put all SATAs on one channel and the speed will stay stable but slower then the next channel that has SAS disks and so on. This allows you to get the best from each class.
Hello, I liked your video very much.
I bought 2 M6710 with 2* 24 600 GB SAS disks. Two HBA's I will still order.
Which one can you recommend me for the M6710?
I plan to attach the M6710's to one server each and thus build a S2D Mirror SOFS cluster. VM's should then be executed there. Everything in the Homelab.
Are the M6710 well suited for this? Or rather only for backup and data FIleserver?
Thank you very much.
I used the LSI 9200 series HBA controllers 4 port outputs "External SAS connectors". Get it the way you need it for your server setup.
Hello Leadius, thanks for this video! I'm getting a strange problem. Bus 1 (disks 1-8) are showing in error status (all have orange lights) but the RAID6 array is working fine!? When entering the RAID config (using a P812 card - great card) it shows 'Box 0: Bay 0' and doesn't label any of the disks properly. Is it possible to manage/configure/fw update this units without the original HP StoreServ controller? Thank you. Tim
I thought I'd come back and report my findings! I wanted to deploy this PDQ so I needed to find the issue. I can report that in my case the HP Smart Array P812 Controller with 1GB cache was not compatible. I ordered a SFF-8087 to SFF-8088 cable and tried the the storage enclosure with a MegaRAID SAS 9260-8i and all working okay!
Hi, do you have the idle power of the M6710 with no drives / drives?
Also, does the SAS controller work in a netapp unit? Like the Dell-COMP controller does? Can you try this?
No not off the top of my head. but I think runs around 285 to 400Watts but that depend on you using one or two PSU to power the server. You can us this one device to track this. ( www.amazon.com/Digital-Electricity-Analyzer-Monitoring-Equipment/dp/B07M8JKLG5/ref=asc_df_B07M8JKLG5/?tag=hyprod-20&linkCode=df0&hvadid=309819400004&hvpos=&hvnetw=g&hvrand=12021544539510275576&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015806&hvtargid=pla-608358363795&psc=1&tag=&ref=&adgrpid=60510211606&hvpone=&hvptwo=&hvadid=309819400004&hvpos=&hvnetw=g&hvrand=12021544539510275576&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015806&hvtargid=pla-608358363795 ) or go to the Dell spec power usage PDF. That should help you ID the power rates. I personal like the wall Wattage test device for it tell you the real number based on your usage.
Hi, really like your videos. I am really interested in getting my hands on a M6710 or M6720. At work we mainly use Dell servers, storage and switches, and always found that we can use every hadr drive / ssd in DELL systems, whereas we had read a lot about compatibility issues with HP in regards to only allowing for certified parts. Can you comment on diversity/compatibility of the several manufacturers like HP, DELL, EMC, NetApp etc..
Well when you are working with a arrays then you are working with a protocol unlike manufacture makers of server gear that is specialize a lot like you have said. So I will go with A NetApp or EMC disk arrays and even 3PR arrays because they run only on the SAS protocol only so it works. I prefer the NetApp DS2246. Hope that helps...
@@leadiususa7394 So you can stick any hdd/ssd inside the 2246 shelf and it will be recognized?
@@marcon.6442 I have and it works for me. IT really is up to the controller and not the array. Sometimes a HBA or RAID controller may not like a SSD but I use the LSI 9200 series and works pretty well. (the easy fix is to flash the controller BIOS to the latest update.) Now mix mode not so well unless you put the disks in as groups and group them together by type when using them. What I mean is that if you put five SATA drives then five SAS drives and then five SSD drives. Make sure they are grouped by type. Then make your LUN / pools of storage by type. Do not mix them for it will not be pretty I/O bandwidth wise. Outside of that have fun playing.
Can we clarify exactly what SAS connectors are needed on the cables? to connect the controllers and to the HBA.
Sure, first ID your SAS controller and the type of SAS external connecter it has, both Mini SAS and SAS connectors are out there. Then make sure you ID the SAS connector on the back of the 3PAR. And you are done, order the correct cable (either a SAS to SAS cable or SAS to Mini-SAS cable) P.S. Make sure you ID what a SAS and Mini-SAS vs. FC or Fiber SFP connections. Enoy!
Any chance this would work with a newer HPE E7Y20A (HPE 3PAR 20000) enclosure or stick to M6710/20?
If the Server HBA controller and the disk array controllers are both SAS connection, you are to go. Any will work. Just make sure you have the SAS controllers in place. Some 3PAR come with IP base controllers for the NAS role. Your call. Have fun dude!
I have a bunch of 3pars I just bought and playing with them after building a custom server with LSI HBA cards. Is it possible to daisy chain a full rack of 3pars and connect to a single LSI card on a server?
Yes you can. Just pay attention to the drive support of your HBA or RAID controller so you know your limits. This is done a lot. Not easy on the power consumption side of things.. Enjoy!
Hi Leadius.
Great video. I went and buy two M6720, but I am having two problems and I was wondering how you had the same, and if so, how did you overcome them with your M6710:
1. No matter which drive I insert, one minute after inserting the drives, the amber light will go on all of them, which I understand is a bad disk, but the controller will see them fine.
2. The controller sees the disks but the bay shows as unknown.
My Setup:
HP Server with P822 controller (Also tried an P800)
Windows Server 2012R2
Two M6420 ( Only one connected)
12 8TB SATA Drives (New)
5 1TB SATA Drives (New)
Any help will be apreciated,
Thanks
The first thing I would recommend is to go with only one Disk controller (In the back of the M6420 and make sure the second controller is pop out of it slot.) with one SAS hook up in port A. (for now...) Next your P800 or 822 will work fine and the alerts and amber LEDs will go away for now. If you want to add the second self to your model then just go to the B port on the back of the first disk array and plug it into the A port of a single controller belonging to the second array. Power them both up first then boot your server up. To use both sets of Disk array controllers, you need a dual set of SAS controllers recommended by HP. Current this config I gave you is a single path fail over. (1x1), to go to a 2x2 fail over you will need more hardware. So most of us just use this setup of 1x1. This allows us to do storage cheaply and still have a solid storage array. If you have the software from HP 3PAR, You could go 1x2 instead, That is single controller x dual failover paths. That requires that you use both controller ports set, SAS controller Port A to Disk array Port A and SAS controller Port B to Disk array Port B. Don't use the second controller on the disk array. Better to pop it out to shut down alerts... Unless you want to a fully deployed 3PAR array... That can have some real costs. Oh also just use about 3 disks to start for you need more then one disk to test things right... Faster reboot times that way.
@@leadiususa7394 Thanks for the explanation and the help. Will do as you say.
Hey! Great video. I've tried to google, but is there any way to control the fan speed of these things? It sounds like a jet engine haha. The data I've got on the drives I don't really care about, so I dont mind if it goes a bit hotter than it should.
It should spin down to a low blow unless you have a fault error on your array. (Look for yellow LEDs or beep codes.) Mine goes load for about four minutes then calms down and run pretty quit. Go to the support site for fault error info. Hope that helps some..
@@leadiususa7394 I can use the drives, no problem. Currently copying data at full speed. It does however say: 54 on the led. I'll try and see if I can find some more info. But there is no way to control it via com etc? The status of the trays is amber, I guess it doesn't like the baracuda SATA drives. Maybe this is not compatible with non HP drives?
@@victorkarlsson5183 No, the drive is not the issue unless you mixed them over and voer. There may be a issue there but you put the one class drive in first as a group then SATA and so on. and your don't mix them, that will work. If you have a amber light you need to check you controllers in the back or look for a dead fan or proper supply and so on. Go to the HP 3PAR support to ID the amber code them swap out the bad part.
What is the power consumption when you have all disks slotted?
spinning drives do run with less power the SSD drive do, It is because SMART is really built for spinning disk management
i have one of these sounds like a jet all the time sucks cause i like it but who want to listen to all that noise, Would love an idea for a fan mod but i have found no info for that.
Sounds like a power supply or a controller has failed. It is not loud unless it is failing. Check your array to make sure it working right.
Can the drives from the 3par be used in a normal hpe server or are they a different type?
Yes, just make sure your disks are formatted 512 and you are good to go... If formatted in 520, just look at my video about convert 520 to 512 and you are good to go..
I have two HP DL380 servers with Windows server 2019 and want to set up a two node windows SQL cluster using an HP 3PAR M6710. Can this be done with the HP 3PAR M6710?
Yes but you need to split the Array bus to share the storage in a mirrored format but you can this a few ways... I is not easy but can be done.. MS SQL is going away from the fail over state format to IP clustering so I ma not sure how long they will support the old way of clustering for it has limits
Are you able to provide me with a link the the HBA card you are using? I just bought one of these off ebay and would like to essentially attach it to my Truenas server

Hello, I have the m6710 already coupled to the dl380 and I have already formatted the disk units to 512. Now I would like to take these disks to other servers through a dl380 fc hba to an hp brocade switch. what would the procedure be like? thanks
First off does the HP 3PAR-m6710 have two FC controllers in the back or are they SAS controllers? I have not heard of anyone using M6710 with FC networks so cool. Check to see if you have SAS controller or a FC controller.. Or other and get back with me...
@@leadiususa7394 Thank you so much for your answer. The connection between the M6710 and the DL380 is via SAS through an LSI 9200-8e card and it's working fine. I've put a FIBER CHANNEL HBA in the DL380 as well and would like to expand the SAS disks across the FC fabric between that HBA and a Brocade Fiber Channel Switch but I cannot see the WWNs of the disks on the switch's fiber channel port.
@@alvarovasconcelos5437 That is correct. The FC card will not show the disks ID thru the SAS controller. SAS is a hard drive protocol and so is FC. They are not compatible protocols. The only thing you cna do here is to create a data pool and download FV storage pool connector and then link that to teh FC card you have in the server. Then provision some storage as a LUN on the storage pool to the FC card. If you zoning is correctly setup the FC SAN switch the traget host will see the presented storage as a LUN for use. BTW this should be done correctly with two FC HBA cards for each host and two SAN switches. If you are following the standard industry guidelines. Hope this help some...

Hello, Nice video. Im wondering if you could help me. Im trying to hook up a 3par unit to my DL380 g6 with a p800. I cant seem to get into the p800 raid config and on boot it says 0 drives. Im not sure what im doing wrong. However i do get a warning my p800 battery is low but im not sure if that would take the option of entering the f8 config menu away. Ive tried hooking up a single cable and tried using just 2 straight cables to the top controller. I do have other cables but the last cable isnt long enough to complete the cercuit with both controllers. Thanks in advance Chris
No, don't do a full loop unless you have the correct type controllers to do that with. A P800 will not do that. First start with just one SAS connection (one cable in the A SAS connection only.) then first go into the RAID controller BIOS to see if you can detect disks. If you don't see disks then something is wrong. Flip over to the B SAS Channel and try again. When you do see disks, set them up as either RAID 0 (each drive) or do a disk group of RAID 1 or RAID 5 and allow them to sync up before trying to see the RAID drive to boot to. Next also make sure that the server BIOS knows to look for the P800 on boot up outside of USB or CD boot. You must select the drive you want to boot to and in order. I would do USB, CD, P800 and so on. Now one last thing. If you flip your RAID card to HBA mode. (In this mode the controller RAID features are turned off and you just see raw disks and you use the OS to manage the disks instead of native RAID mode.) I like to do RIAD for it is native and doesn't care about the Boot OS at all. It just works. /:> Don't get me wrong, HBA controllers are great for adding JOB (Just a bunch of disks) to a server...

Just use one cable and don't try to close the loop. You may get a beep from the disk array but do it any way. Use just one drive for now to discover. Also are these drives formatted in 512 K format. If you bought enterprise disks in bulk, make sure they are not format in 520 or you will not be able to use them. You will need to reformat them to 512. Any way, right now you just want to detect a disk. If you setup one cable connection for single path SAS connection and you don't see a disk then flip down to the lower controller and try again. Email me what you fond out. Thanks
@@leadiususa7394 Thanks Ladius.. I will email you tommorow as its late here in the uk atm. The disks and cables all came brand new with the 3par unit. The disks are all 900gb and still have the seal on. I have a p411 sas controller also arriving soon.
Can I buy any sas drive and install it into any hard drive storage device that a accmodates the drive size? I'm new to networking and storage and I'm confused about whether I can mix sas drives and put them in any enterprise level storage unit. From your video Ivan tell I can connect the storage unit to the server, or in my case a workstation, through the raid card as long as it has the connector. I found out that raid cards have the raid management utility on the card. So will my os see the raid array? I bought windows server 2016 datacenter and windows 10 pro or something. Thanks
No need to worry about drive types the key thing is placement within the array. SAS bus connectors can hook up SATA, SSD and SAS. the key thing is to understand the when you pick the drives you want to use, you group them together to get the best speed from them. So let's say you get 8 10K rpm speed SAS 1TB drives and you also get 8 15K 512 GB high speed SAS drive. When you go to your RAID controller BIOS to set them up or if you choose to use a HBA controller instead. Make sure your raid groups or SAS pools keep the drives apart from each other. This will give you a good response. Also one other thing is to learn about the group channels of your disk array. Some have 4 bus channels and some others have 2 or 8. Placing your groups of 10K, 15K or SSD drives (or slower including SATA disks) with in each channel. So for a 4 channel you have your 10K or 15K disks group in the first channel of 8 disk slots and the other group in the next and so on. Us poor users can do four different drive class in a single array if they are each on their own buse channel. It is cheaper that way. It only goes south if you intermix them all together. Not good and everything is slow. Take some time and play with it. I use RAID alto but take your 3PAR (if you have one of these...) and move the disks around to get the best results. If your boot disk is a memory stick or USB drive this will not take long to build and rebuild your disk groups for the best results. Enjoy!
@@leadiususa7394 Im looking to buy a sas lff hd lot on eBay. Might spend between 100 and 200$. But the issue I have is what to plug them into for the array. I could make a diy storage unit but I'd have to buy a power supply with enough power and connectors for up to 15 drives. So I'm looking at eBay for storage array units. But the question is are the units considered jbods until you co next them to either a controller or a raid card? And then the question is can I use any pcie raid card to create and control my raid array? Or does the storage unit dictate what controller or raid card you can use? For instance I'm looking at Seagate NetApp drives and they apparently were designed to work with NetApp storage devices and those devices plug into the NetApp controller. So can I bypass the controller and plug the array unit into my pcie raid card instead and it will work?
@@anthonystrohmayer9191 I would recommend the NetApp 2.5 inch DS2246 SAS disk self or if you are getting a 3.5 drive then get the the DS4246. Both do all SATA / SAS typee drives. Then for your RAID controller get the HP 800i series controller for it has external dual SAS outputs. But one thing. Your cable to the RAID controller have to Min-SAS to SAS cable sets of two and then one cross over mini-SAS cable for the disk array A bus to B bus. That is it. One last thing. If you buy a bulk load of NetApp disks, you will need to reformat them back to 512 sectors format from 520 formatting before your controller can work with those disk.(Any controller for that matter) Great disk to buy but you got to prep them first. Don't worry, I have video talking to this point to help you out. P.S. if you want JBOD mode get a bacis HBA controller and you can use that controller to reformat your disk as well.

Is this controller hba or raid? If it is a raid can it be flashed ti an IT mode and passthrough the disk instead of presenting them as virtual disks?
What is the equivalent of an iom12 controller in HP supporting sas3 12G drives?
You can do both. HBA is the most popular as I understand it but I used them both.
@@leadiususa7394 Nice..thank you. When you used it as an hba, could you see smart stats of your disks from the hypervisor or OS? If not it s not a true hba. It would remind me some Dell,'s controllers who while they have the option for hba mode as well, they aren t a true / native one With zfs for instance..many bad things might happen...the least of the them false logs for the disks health during scrubbing
@@ierosgr Well that is close to being true, the RADI controller that flip to HBA mode run in a old format and that will not report to newer storage standards such as ZFS for the controller is working at the hardware level and not at the OS level. These controllers work below the boot level. So no ZFS can't go down that deep that I have seen. But you can get some info if you are using Smart drive reporting. But that will only work if the hard drive will support that mode. RAID base controller offer a lot that HBA mode doesn't and HBA mode has a JBOD level of value as well. I use both for their strengths. SO enjoy the mode you need the best for your goals.
How many of these could you put in series? I wanted to put 4 of them in series using the card shown is it possible?
It is control by you sas control. It can up high if you have a higher end controller.

Did you format from 520 sector to 512 sector? The good news is that you got it all hooked up. Also how long to each drive take to reformat? It should have been a few hours each to doing a low level formatting.

Most of them are incomplete, and since i'm a beginner i don't want to search and spend a fortune on parts... But seriously, i cannot even find one single complete disk-array unit.
Sorry for the rant, i like your video, but without the hardware i cannot build one like yours xD
Why don't do this. First get your chassis with two PSU power supplies. No controllers, cables or Disk caddies. Next get two SAS controllers and three 1x SAS to SAS cables fr the controller in the arrays to pair up and 2x Mini-SAS or SAS to SAS cables (This depends on your SAS controller card hook up) This will allow you to post and test your Array. Get the empty chassis with only PSUs will also keep your shipping costs in check. Next when you are ready get up to three disks with caddie (300 GB) SAS 10K drives are really cheap and may be able get these locally. Then after that you have us out here to help you out for that is my goal. To be helpful.

We recently migrated all of our data off of three 3-par Storeserv 7000 arrays. I have a boatload of the M6710 trays. We were about to give them to a tech recycler when I came across your video. It got my wheels turning and consequently decided to attempt to use them for a JBOD environment for our Veeam backups. They are populated with 900GB disks and I currently have 5 trays connected to a perc H200 installed in a Dell R720 server. I appear to be running into a hard limit. The H200 sees all 120 drives, but it appears that the lifecycle controller on the server only recognizes 111 drives. Consequently Storage Spaces only sees the 111 drives. I need to add two more trays to our environment to reach the capacity I need. I am wondering if anyone has any suggestions for me about how to do that, be it hardware recommendations, or configuration changes. This has been a fun project. Thanks for the video!
Well, I used a HP DL380 G8 deployed in a bare wire format (As in no blot-ware / life cycle service running) with LSI 9200 series HBA card and I could see everything. Are you running in HBA mode or RAID mode on the controller/s? I am not sure of how your controller/s are setup...
@@leadiususa7394 I am running in HBA mode. I figured out that there must be a 4 tray limit per controller. I added another H200 and connected the additional two trays to it. I can now see all drives and have 117TB presented to StorageSpaces with parity and 1 hot space per tray.
BTW, write performance is terrible for the first full backups, but pretty quick with the incrementals and Veeam fast clone synthetic fulls. (I meant hot spare in my previous post)

I was wondering if it is possible to configure it so that the drives show up as individual drives instead of a raid? And is it compatible with 18TB drives?
Well yes if you are getting a m6720 24 3.5 drive array. That should work for your needs. You will also need a cable for SAS/SATA hood up to a SATA/SAS LSI HBA controller (single drive mode...) and you can also use a RAID controller but just make each drive a RAID 0 drive. This make all the disks act as single drives. As for the size of the hard Drive, check the specs on the HBA or RAID controller you want to use to know if you can do 18 TB drives. I am pretty sure it will work but do your research what you are buying. /:> Enjoy!
what type of raid is recommended for hp 3par m6710
Any that you want but most Admins do RAID 5 for basic storage or RAID 1+0 for app level storage need but you have to play a little bit to tweak it out some. Refer to my other response to your needs...
Ok, thanks for answering I tried with raid 10 but I did not understand since it left me unused discs, I will try raid 5
What is the SAS card you used in this vide?
I used a mini SAS to SAS cable and also used a NetApp SAS to SAS cable... The HBA controller controls what cable you use on it end and the SAS end on the back of the Disk array. There are a few options so ID your controller cards first then get the correct cable for your needs. Also you need to add your drive one at a time for the first time to make sure the HBA can see them. What a pain I know with some controllers but it works.
@@leadiususa7394 What is the SAS PCI card you used? You mentioned that it was a good card but didn't mention which one it is :)
@@WalterBoring I used both a LSI 9200 series SAS HBA card and a HPseries 800 SAS RAID card from a DL380
I'm having the hardest time trying to get this working in my infrastructure. The cable hook PDF has a bad link. Could you explain how you got yours working?
Sure, now for use I am only using a single server node so that is what I am referring to. The server side SAS connection from a HP raid controller or HBA controller will need to firs go from port A and the disk array top controller to the A port (left side) on the disk array, Then on the disk array (left side but right B port) goes to to the disk array lower controller to the left side A port. Then the lower disk array right B port will go back up to the server B port on the controller. Here is a Link to the manual. This is only for one disk array to a server host, but it is very easy to add more by just adding into the cable series. support.hpe.com/hpesc/public/docDisplay?docId=c05163419&docLocale=en_US
As for a possible bad SAS cable. Get yourself a new spare cable to use as a test cable. Make sure it at least three feet long or better. That way it works as a test cable for all of your cable testing needs. I use a 5 FT. SAS to SAS and I also a Mini-SAS to SAS cable myself to test my NetApp disk arrays. Hope this helps you some!
Leadius USA thanks! This will help I think my first issue is that I purchased a SmartArray card and not HBA card.
@@every1critic Side question, Are you recycle NetApp disks for use with your array? If so they are formatted in 520 sector formats. You need a HBA to reformat them before they can be used. Just a heads up. These disk are really cheap to buy but do need some prep before using them, some EMC, and IBM has the same challenge. Refer to my other video talking to reformatting to help you out.

@leadiusUSA I want to buy one, I want to use a poweredge t310, how can I connect? Can you do a video?
Yea, I did a video or two on this already. Really you just need to do your research (You need to know the basics...) on a single SAS cable hook up and get a SAS controller (Like HP 822 SAS controller) then you can setup either RAID or HBA mode. Remember to use only one SAS cable on the top controller in the back of the SAS disk array. Pop the bottom controller out for now. Until you want to add another disk array to the mix.
@@leadiususa7394 I see in this video how you explained how to connect the cable - I understand that. So I would need to buy the card and pop into the server and from there program the card.
And particular software you like to use to run the array? I was thinking of using freeNas?
Thanks for the reply
@@how2374 Well it depends on if you get a RAID controller or a HBA controller. With RAID you setup the disk groups inside the BIOS of the controller. The is no real OS level software needed outside of the monitoring software. Let do this. first ask what to do you want to do with the disk space. Use it for VMware, or IP storage for a NAS service or a media server for your videos? Make a list of what you want to do with the disks. If you want use the disks for VM machines then create a RAID 1 group and have one spare disk for fail over. If you are just doing NAS storage then RAID 6 with one spare, any between RAID 5. If you choose to use HBA, you can't set anything up in the controller BIOS. It has to be done at the OS level.
If you use a HBA controller then look at using TrueNas.com and use their free disk manager software called FreeNAS. HBA controller have some value when doing thing this way. Sorry for all the writing...
Hello Leadius!
Can you please clarify on the subject of HP Being a relatively closed ecosystem if the 3PARs come with any licensing drawbacks?
Does any 2.5" fit as an almost plug and play? can someone who's just starting out in the enterprise space buy one of these off ebay and not worry about being locked out of the device for not having the proper licenses?
Or does the license only apply if you have the mother module? as in the 3PAR just acting as a dumb shelf, no licenses would be needed?
Question 2, does the 3PAR work on a 520 byte or a 512 byte?
Question 3, does the 3PAR system support daisy chaining? as in wanting to connect more than 1 in sequence to create a large storage pool attached to a main server as a controller rather than a mother module? are there license fees/limitations that?
Thank you,
I'll answer what I can, I'm also looking to get into the 3par system,
The disk shelves m6710 and m6720 with just the SAS controllers (not the 7200/7400) can use any SAS disks, and can use 512 byte sectors as they are basically just a SAS controller.
They can be daisy chained like a standard SAS enclosure
The 7400 controllers need the disks to be 520 byte as they act as a SAS controller themselves, whereas the 6710/20 just provide a SAS connection to your HBA/RAID controller
I don't know about licencing but I think that only applies to the 7400/7200 controllers

If good then format. Then you should be able to use it. If not you may have a bad drive.
3par storage is good for file storage and backup storage, middling for small database storage, and absolutely HORRIBLE for VM storage. I know this because I work at a cloud provider that uses several 3pars (3 in Colorado, 2 in California, 2 in Chicago, 2 in Virginia, and 1 in Georgia) and they can't even handle a snapshot on a VMWare VM without bringing the VM to a crawl. We are forced to do all our customer backups during off hours because of this, which creates quite a problem for some customers with large SQL Server VMs.
The reason for this is because of how they arrange the disks. They group the disks in sets of 4 in RAID 5, and then divide chunklets of 256MB spread across the disk sets. So, the maximum read iops is can get is what 3 drives can put out and write iops is about what a single drive can put out. Because of spreading the chunklets across the disk sets means if reads from more than one VM hits a set, which happens often, slows the continuous iops available to the VMs involved. In exporting VMs directly from ESXi hosts with nothing between the host and the target of the export (a VM on another host) being one network switch, we are able to get 5-8MB/s, taking forever for VM exports.
Yes I agree. About the only thing you can do to help this is to flip to a eight disk raid group (RAID 1/0) ands set your write value (you call chunklets) to something like 16 to 32 MB write cycles. 256MB is really only good for blob and large zip files relating to basic IP NAS storage, That is bulk writing. No good for VM or DB. I would set up some the storage if possible for 16 MB for DB and 32 for VM. This will be faster and smaller write cycle so you can avoid I/O wait state on the I/O bus. Hope this helps... BYW if your controller I/O path ways are setup in 2/2 fail over then then you has ALB SAS controller setup. Doing this and having multi path ways as well, will show an improvement. (Only if you are not doing to much workload that is.)
@@leadiususa7394 Unfortunately, I'm not in our Storage Engineering department, so I have no say on such settings. The fabric is set up with failover and two separate fabrics for redundancy at every location. So, we're good there.
Our workload, however, is another matter. We're down many customers lately, having lost three of our major customers specifically because of our storage problems, and the workload is down from what it was. It's still pretty heavy in a couple locations, and those have noticeable problems.

I don't know how to flash my raid card and I don't think I want to bother. It's simply easier to not flash anything in the first place
For the HBA card you use the OS tools to see the drives for the HBA controller doesn't have a RAID OS on the board. (That is why they are so you can see disks in basic format.) A RADI controller does have a RAID OS on the card and will let you see the drive but not use them until they are 512 sector formated. TO know how to use the HBA controller go to the video I sent you about formatting 520 sector drives. They walk you thru the Centos linux steps using a HBA controller. That is why I have a USB stick with Centos and the formating tools on it. It works.

OK so I had to rebuild my unit up again with my P800i RAID card and the 6710 with my two 7000 SAS controllers in the back. I defaulted my 6710 When I setup array and it failed. Hmm so I saw when I built the array top controller was flip one way and the lower one was flit the other way. RAID port a to SP-1 port / DP-2 port goes to lower controller DP-1. Then the last connection when DP-2 to RAID port B. The paths showed only four LED for controller and I saw the issue and yes I got an alert peep. The config default back to four hook ups such as a HP 822 card being use. So I pulled out the lower controller so it was off. (It must be remove to force a single dual pathway. (not dual / dual pathway.) We only have one SAS array so we run in single dual fail over path. You will get a single peep every 20 seconds but all the drives come and can be format and use. Now to test your disk bus channel on the array. Place one drive for every 6 bay slots. So put in bay 0, bay 7, bay 13 and bay 18 like I did. Now go into your raid controller and set each drive up as RAID 0 each. Not together but as stand alone RAID 0 disk drives. next boot into MS server or Linux and detect them then format them and test a data dump on each of at the same time and see the transfer rates. Now to get rid of the single beep, when you put in your 822 controller card with four SAS ports and port 1 goes to DP-1 on the array top controller, then connect the DP-2 back to the RAID card port 2, now do that for the lower controller to complete the config using port 3 and 4. You are running in dual / dual pathway. This setup is really built for connection two or more arrays to one storage server. As for my peeper speaker, I'd tape over it so I barely hear it. (lol) That took about four hours of fun... See if this works, for my server (MS server 2019) is using these drives in single dual setup and works well. BTW I had a back disk in bus bay 0 and sent me on a path I didn't need to go. Make sure you test drives are good for use. I didn't check so I assumed it was good. (Make ass out you and me) Not! Later dude! Hope this helped you some.

Yea but don't worry so much on that front. Are you trying to buy in bulk or one at a time?
@@leadiususa7394 I bought a raid shelf that purposely came with the drives and cages to save me the headache of finding compatible drives and cages. But I have this project of making a diy shelf for hard drives and raid connected to either the mini sas or from inside the computer case on the mini sas connectors on the raid card and I needed a set of matching drives 8+.
@@anthonystrohmayer9191 Yes but they do not have to be the same make and model. Just by size. I have been doing this for 29 years now and it work with mixing as long as you don't mix RPM speeds. If you really want to get the same set of disk then shoot (For now...) the 300GB 10K SAS disk drives. Do you have a 3.5 drive shelf or 2.5?
@@anthonystrohmayer9191 here is a 300K 2.5 inch SAS Dell hard drive you can look at. www.ebay.com/itm/U709K-Dell-300GB-10K-6Gb-s-2-5-inch-SAS-HDD-Hard-Drive-HUC103030CSS600-0U709K/282651157882?epid=177505943&hash=item41cf52657a:g:M6QAAOSwTMZbhKpL Also are you using a RAID Controller or a HBA controller? If it is a RAID controller then you only need 3 or more disk drives to get your storage started and you can grow it out as you get more. HBA format is doesn't matter for you need a software RAID OS to do anything so 2 or more drives will work. Also if anyone tell that you must have the same make and model of drives, they are wrong. That only applies to enterprise level systems and that is not what you have based on your goals.

This is but a single disk expansion shelf of the 7000 series 3PAR can support up to 240 disks configured over ten disk shelves for the dual-controller 7200 model and 576 disks for quad-controller 7400c model. The system is managed via the 3PAR IMC (Integrated Management Console) or newer SSMC Web-type management interface or lastly the CLI interface. Basically, using a 3PAR expansion shelf without the actual 3PAR controllers dumbs down this complex 3PAR SAN to just a old-school SAS based disk expansion shelf. In addition, A 3PAR without HPE Support is also kind of useless for anything more than SAS expansion shelves. The actual 3PAR SAN is so complex and proprietary that things like software updates and troubleshooting can only be performed via remote HPE Enterprise Storage support ($$$) with a password only they know! In other words, using a 3PAR outside of support for anything more than a hobby is kind of like trying to fix computer regulated inverter issues on a Tesla Model X with a 1980s Chilton Car repair manual. 😄 I've been a 3PAR Admin for 9 years btw and took the $4000 class.... Lastly, never place a HBA or SCSI/SAS Controller like the author did on a metal surface or you risk shorting out the electronics and I'll give you a 👎. 😁
The goal here was to take a unit like this and reuse in a newer way for I don't really like 3PARs till I was able to use them in other formats to use the arrays for fun. Yep! I said for fun for that is what this was and is. I got these array shelves for $50 each for no one really like them much but I had some fun and shared my insights for others to enjoy and buy something cheap that they could use and the walk thru was free. Oh and BTW if you saw my (how to correct work with PC systems) you would know that the work bench was completely ground and static shielded. Been doing this for 33 year but thanks for the heads up and yes you need to worry about discharge. Have fun doing this stuff and reinvent if you can! I hate waste...
