What not to buy when picking a Disk Array on Ebay for your home lab. Say no to Dell MEMC KTNSTL4 FC

- This video talks to two types of disk arrays. SAS and FC (Fiber Channel) I explain why working with SAS DAS works bests because you only need a controller and cabling unlike like FC arrays. Fiber channel arrays need a FC network and VNX or other controller arrays before you can use them. Much more overhead... Enjoy!
Hardware involved:
EMC SAE 25x 205 SAS/SATA SSD JBOD array - SAS DAS
EMC Del KTN-STL4 15 bay 3.5 drive disk array - FC array (Requires a CX3 or VNX to run.) - Věda a technologie
Newbie here: I hope one day I can fully understand this video, thank you for uploading
I have deployed a few refurbished SAS shelves to clients who needed more storage for their off-site backup cache (so failure would have minimal impact) - what a simple-to-use and huge value those are. Great idea for a home lab.
Totally agree
Thank you for explaining this concept
The biggest problem with EMC on the secondary market is that the FLARE/OE disks are normally trashed or wiped. You may buy yourself a nice VNX 5200/5300 cheap, but EMC/DELL won't give you the time of day without a support contract, and the binaries/activation CDROMs are nowhere to be had.
True so you need to vet the seller a bit as I do. one out of ten buys I have a issue but so far I can address them without any support from the vendor. So far. But for getting a array for $75 I will take the risk. Try it. Vet a few vendors on Ebay, never buy without a exchange coverage so you can swap out parts if bad. It works...
well done for explanation.you are amazing
I have two of those arrays now and I love them, they're surprisingly efficient as well and they will work with any drive. I currently have one filled with 8x 200GB SLC SAS SSDs, 9x 400GB eMLC SAS SSDs and 8x 1.6TB eMLC SAS SSDs all with matching caddies witch were a pain to source.
Yea, I use the 3 TB ssd drives myself. It run well, I agree, the caddies can be a pain to source out.
I still have that disk shelf I bought 2 years ago and all those sas drives. I even bought an hba card. That's as far as I ever got. Haven't even installed it.
Do it when it works for you dude... Have some fun and learn something but only when you are ready
God Bless
Outstanding! Subscribed. Ring, Ring. The depth of consideration is applicable to many different purchasing concerns. I especially appreciate your informed thought process. Dell EqualLogic PS4100. Have you ever used the PS4100 2.5”?
Yes, I have use them but on a limited format. We played with IB and some other standards but saw the costs at the controller level and so other issues so we flip to SAS/DAS for my home solutions.. The Dell EqualLogic PS4100 and it IP-IB series of brother controllers are nice for some key roles but you have to have a lot of costs to get the mt work at the level they work best. Not cheap but nice...
@@leadiususa7394 agreed, I can see the cost to maintain over time. But that concern is offset by my motivations. My lab X3650 M5, 2x C2960s, 2x Cisco 1921 are to prep for an enterprise level position. The ancillary enterprise equipment I have is just to play with Linux.
@@SQUID_Road_Glide Very cool and have fun with it if you got it! /:>
Really my experience of FC arrays is you can put them in an arbitrated loop. So all you need is a FC card and some simplex fibre optic cables and boom you can use them like direct attach SAS shelves. In fact if you only have one shelf a standard duplex fibre cable will do. I think they dropped arbitrated loop support after 8Gbps FC but they stopped doing FC shelves and went SAS anyway I have never seen more than a 4Gbps FC shelf myself. One gets the feeling that there is some Dunning-Kruger going on here.
Blast from the past, you are correct if the HBA that you use will support the single mode. Many years ago we got one to work but the other two HBAs would not do the role like the firs so it was a Flair-code related issue with the array so we dropped it. But yes it could work.
Thank you very much.
I think this is very dependent on the persons setup and what they are trying to achieve. For your setup with one server and using the JBOD SAS shelf this makes a lot of sense, but if you had say, 3 truenas scale physical nodes that you wanted to supply block level support for, it makes a lot more sense to use one shelf and partition the 3 disk channels to three nodes over FC. Your 1 24x JBOD can't supply 3 physical machines over SAS with a set of SSD flash storage. The cost of FC is so cheap now, it makes way more sense to pickup a silkworm 300 for maybe $40 and a few FC HBAs for $10 than to get multiple shelves for multiple servers that need direct block level storage.
Totally agree with your viewpoint. But did this on the basic deployment model because most people can't buy a lot if resources off of Ebay. I may research this more down the road.
Some of this information appears to be incomplete, please comment Leadius USA!
The KTN-STL4 has a sibling, the KTN-STL3, which is straight-up SAS like your 2.5" EMC enclosure. The weird part perhaps is that the KTN-STL3 uses the same caddies (trays) and the same Fiber-Channel backplane ports, but EMC made SAS/SATA "interposer" cards which adapt SAS/SATA drives to that Fiber Channel connector. On the other side of the backplane, the KTN-STL3 sends the data out thru the same standard SAS connectors as seen on your 2.5" EMC enclosure. It's a beauty.
In addition to this, EMC did make, and you can buy, HSSDC2-to-SFP cables to connect one of these KTN-STL4 units directly to a PCI express SFP adapter, bypassing the need for a special switchgear or EMC head unit, etc. EMC also had a few older siblings for this unit, for example the KTN-STL is 2Gbit fiber channel instead of the 4Gbit capability of the KTN-STL4. Also, if toy've got the STL4, EMC did make SAS to FC "interposer" cards to go with the cadddies - it's not as fast as the STL3 but should work fine.
And there's more. EMC even made IDE to FC "interposers" a number of years back, but the enlosure and caddies for them are just slightly different. As we speak I am modifying some KTN-STL3 and STL4 caddies to accept IDE drives with IDE-to-FC interposers, a I've found the STL4 seems to recognize the old IDE drives I tried connecting. OK... the point is, there's a lot more to this, and some of the solutions are fairly simple and inexpensive. Please comment and add ideas, there are a lot of folks who would be excited to see this stuff actually work.
Yes I am aware of those added features and in some rare cases you can get away with some pretty sweet cross busing using different interposers. I use to used to look for them in the past but after EMC was bought by Dell, the water got a little mudder when it came to getting parts. I can still see one here and there but because of how rare they are you have to buy at least one extra jsut in case your interposer interface fails. You need a back. Question? do you have a source for these? I haven't look lately to be honest for I have been in the NVMe and SSD level now. These days I am using well of 300,000 IOPS or higher on my test models these days and that is something that the old days fo FC and SAS/SATA can't do anymore. Even the old school EMC and NetApp controllers are not able to do this level of IOPS. Let me know what you know and thanks for the feed back. This was a good talk.
I recently picked up an STL3 off ebay, and then shortly thereafter an STL4. Also grabbed the appropriate interposers and cables, and now have 30 drive bays for my latest hobby - chia. The STL3 is connected to an old desktop running ubuntu via an LSI 9200e, and the STL4 is connected to an r510 running ubuntu via an LSI 7204. Since speed isn't an issue for me this old hardware is a cost-effective way to provide a home for a load of old enterprise sas drives. Question: anyone know how to lower the fan speed on the STL4? Sounds like the shelf is trying to take off!
@@cryptoelder Check to see if you have a failed fan or fans. You have to look close to see if there is any failures in the PSU and the chassis. Sense you are not connecting it up as a complete system with COM cables and so on. It can't tell you if you have a issue. All it can do is spin everything up at full speed to address the possible lost fan/s. Check that first. Have fun dude!~
I literally just ordered a STL3, soo just to make sure, these will accept SAS drives right?? like even SAS SSDs, I was planning to use it as a JBOD of SAS HDDs and SAS SSD Cache drives and connecting using the SAS connector to my host. And then create a SAN over fiber channel from that host. Would this work?
Thanks for this feed back for I only focus on a few things in my video but yes you are correct for most of this and the other type class interfaces like IDE, I have not worked with much so I am not sure.
Did you need to convert the disks to 512 byte format at all? Does the SAS shelf work as a JBOD array, or does the controller handle RAID? I'm considering getting an EMC SAE VNX to connect to my TrueNAS SAN.
Yes, yes and yes... Yes the array will do any format but 512 K is preferred. You can do JBOD or RAID based on your SAS controller. I would avoid connecting full blown VNX to your server if a couple of arrays will do the trick. Having a controller array with disk arrays is a headache... Enjoy!
Why would channel groups be necessary? For example, when I had my HPE blade server attached to an MDS600, I was able four different storage pool zones. I was able to assign different hard drives (provided that they were in the same drawer) to a particular zone. The SAS switch was in the blade chassis.
Sure you can do that and yes that is allowed. The goal here was to max return and performance by type. First the SAS channels allow for correct bus so you can reroute with out lose of performance secondly it allow for dual pathing but if you group all of the same disk type for normal operations and not cross over drive classes like SATA vs.SAS. drives in the same channel You will get that max return for your disk pools plus they are grouped by default for your HBA disk pools. can you replace a 1TB SATA from SAS 1 TB dirve on the same channel yes but you will see the drop. Slowest ship of the fleet and all that. having two different type class drives on a single channel will require the controller to add a wait state to do checks that are different then the SATA drive. This was about maximizing a old SAS array to ge the most from it. Yes you can do what you say. But why not try to max it out. Check out how I got NVMe drives to work on this old array. That will blow your mind that you can move to NVMe instead of spinning disks. But you will not get eh I/O that you should with them for the I/O of the disk array is the bottleneck and not the NVMe drives. But it was fun and the heat levels when down and not as noisy. Great question by the way... Keep having fun with your IT goals!
@@leadiususa7394 The MDS600 that I was using, is a 6Gb device. What that means is that if I even have a single 3Gb hard drive, then the entire performance of that drawer was demoted down to the lowest speed. So, the RAID controller in the blade, the SAS switch, the I/O controllers in the MDS600 chassis and my Dual-Port SAS drives all had to be 6Gb compatible. The only thing that I was never too sure about, was if it's okay to mix 10K and 15K spindle speeds. The MDS600 holds two 35 hard drive drawers for a total of 70 per drawer. I believe that dual SAS controllers could handle up to four drawers. This makes a total of 280 hard drives with dual fail-over paths. The successor to this was the MDS6000, which I've never dealt with.
can you tell me the model of sas enclosure you are setting up with the ssd's i have found several on ebay but they are saying they are sas only. Which struck me funny because you have an adapter on each disk sata to sas did that come that way with yours or did you purchase those separately.
Sure, the model is EMC SAE VNX VNX6GSDAE25 2.5 SAS / SATA SSD Server Hard Drive Array Expansion JBOD DELL and I use SAS connections to the backend controllers to connect to my LSI controller. Works great!
Do they make iSCSCI controllers for the SAS drive shelfs? I literally have 4 x MD-1200's but they all have the dual SAS controllers. I was trying to make one a SAN for my entire network as opposed to having it locked to one machine.
Well... You can connect your SAS disk arrays to a basic server connecting by a cheap HBA SAS LSI controller and then use the iSCSI as a protocal with Linux or Windows. You can also add a NPU NIC that handles (offloads iSCSI traffice) for better access but that is the poor man FC SAN solution. You asked about a SAN and is FiberChannel connectivity and no you can not do that. FC is not SAS/SCSI or SATA and it is at the DM (disk management) protocol level. But you can do FCoE instead. (Known as Fiber Channel over Ethernet) You can route SAN FC like traffic over IP this way but it is not easy for you handle every liek you have SAN network but with in a IP network. As for the question can a Disk Array as a stand alone do IP / ISCSI ? some can like the HP 3PAR 6710 array and dell solutions but most need a server or a controller to connect to. Hope this helpos you some...
recommendation for 3.5" disk shelves on eBay? Plenty to choose from but you make the wrong decision and best case scenario you spend hours trying to troubleshoot issues. Worst case it simply won't work without using proprietary servers.
Agreed, that is why I go mostly with open ended (SSD rated) NetApp SAS disk arrays and some older Dell/EMC open ends SAS arrays. These work on most raid and HBA controllers with no special needs or extra hardware outside the normal stuff. Avoid FC disk arrays at all costs unless you the correct controllers to run them. BTW-Research is part of the fun... Enjoy!
you mentioned 3par having their own issues but didn't cover what. I'm considering getting my first disk array to connect to my DL380 gen8 and was considering using a 3par M6710 connecting through the SAS but after watching your video, I'm no longer sure.
Yea, the issue is that the controller want HP controller so you have to be force to run single channel path to avoid the alerms and that is a pain. Once configured the 3PAR works. But I recommend you going with the DS2246 array. They are pretty cheap and easy to work with. Here is the link to one version ad it cost. Hejoy! www.ebay.com/itm/202852351593?epid=1534596049&hash=item2f3af13e69:g:1qcAAOSwZwld8qkh&amdata=enc%3AAQAHAAAAoCiSVw2oMcQsAG3mzjTF6QPVRAGdc%2BObGdkPc2GyO9Obu%2F7Sa0zhBi%2Br2644rPb39f0gOajwdbj3HdAZh0IIEsCw08fYjhKV0%2Bcv8Giq%2Brs0cLmN4ciT8JHUWpfjtpFkMTzE6m6fV5DPhQjlMtggCgXPBz2LQq8Igy732bq%2BC1l%2BHOz%2FECjQsKD4yLSvBYR9ph%2F2%2FVP5CkibrGWh9vRXmms%3D%7Ctkp%3ABk9SR86f_sewYQ
@@leadiususa7394 would a hp 221 solve the issue? Currently orderer a lsi 9200-8e but I would consider getting a hp221if it would solve the issue. In europe, 3par seems more accessible than netapp storage arrays. Thank you for your previous explanation.
@@bogossogob Well I use the HP 800i card but it should work. The key thing with 3PAR is it want a correct path set and if you don't have the dual controller setup as recommend configuration. The DS2246 doesn't canre. As for SAS disk arrays pretty much they take anything that is SATA/SAS/SSD so it's the controller that is the pain to work with.
@@leadiususa7394 by dual controller setup you mean a full loop? eg: server controller first port -> port A in 1st controller (3PAR)-> first controller (3PAR) port B -> second controller (3PAR) Port A -> second controller (3PAR) Port B -> server controller second port? Sorry for all questions but it's my first disk array, still a lot to learn
Are there any good 3.5" jbod fibre channel disk arrays? Or to eventually use in raid1?
Well you can get a NetApp DS4246 Disk Array Shelf 6/GB W/ 24x SAS SATA Trays 2x IOM6 Expansion JBOD array. They run around $190 avg. Real cheap but do you research for the needed parts and cabling.

Check the type of controllers available and do you research but yes you have a few options...
@@leadiususa7394hanks, just ordered one of these 25 bay EMC storage arrays. They'd just work out of the box without any licensing or anything right? Like a JBOD should.
For the time being I plan to just run them on ethernet from a unraid server.
Can you also recommend me a good HBA card for the host to connect this to. Sorry to take up your time, really appreciate the reply :)
P.S: after watching your video, I ended up ordering the 2.5" array and a STL3 3.5" array, they seem to be very worth it, especially for short depth racks like mine.
@@OT-tn7ci No problem and glad to help out, Yes nothing is needed to use these arrays as JBODs arrays. You just need a HBA card and a good server chassis to use it with like a Dell R710 or 720 that has lots of RAM for you TrueNAS or Unraid so you cna do some nice RAM caching. Get your self a LSI 9200 HBA controller card 2200 6 GB or better but do your research first. You can also use a Dell RAID card as well just need to have the same type droves. That is all. Remember that you use SSD drive in any format like I do, the SSD drives will max out your 6GB bandwidth. Hey dude, have fun with this. Hope this helps some.
@leadiususa7394 Love the video. I am using a Dell R720 for my homelab (very new to the game) realized that Its going to be very very very expensive to get storage with 2.5" drives. Im trying to figure out how to add 3.5" SATA drives to the Dell and not break the bank. Im running proxmox and have TrueNAS running on proxmox with TrueNAS getting access to the LSI on IT mode, so it has full PCIe passthrough and direct access to the drives. I was wondering what I should get to essentially move away for the 2.5" drives and add 3.5" drives thats quiet and not going suck a lot of power. I have the Dell R720 running right next to my bed actually and its torarable. So hoping to not add something thats louder. The goal is to have around 15-20TB of space(currently). So nothing carzy. And should be able get this with around 4 drives with a single drive failover. Love to get some advice.

Will I don't know if you can take a EMC KTN-STL3 6 GB and place it in a FC controllers or in reverse but I would say it should work but! Not in real time fail over. Just in case you were wanting to do this in real time with your live systems. Do to the protocol swap. I say that the controllers are pretty cheap so testing this may not be a big deal cost wise to try. Hope this helps sorry not as good as I would like but have fun with this! Keep me in the loop.
Thanks for the reply. Nothing is currently running. I just have about 15 stl4s with 159 300gb fc drives that I don’t know what to do with. Any ideas? I was thinking CHIA but I’d rather just sell them I think. I just can’t find a market for them
@@DP-nw3lz Yea, you could do them (FC drives) in raid 0 group spanning of four drives, (You need about 800 GB for CHIA to work right on avg.) that is about it on the CHIA front. But I would sell most of them if you can and move to newer chassis design that can allow you play with NVMe space and SSD on SAS or IP based storage arrays... I like did... Enjoy!
@@leadiususa7394 thanks. Is there a group of people that might be interested in buying them? They don’t really sell on eBay
I found an EMC with caddeis (empty) locally for $100. Do you think it's worth it? Does it work with SATA drives? How about the noise? Is it ok for a home lab? Thanks!
What is the model number of the array? Need to know that first real fast.
@@leadiususa7394 It only says EMC model SAE on it. Controller model is 303-104-000E (has two of them). Thanks!
@@andycristea So that SAS controller belongs to a EMC SAE 25-Bay SFF Hard Disk Expansion Array . Very good array to own and it is not load after post power up mode. It does SSD/SAS/SATA/NVMe (with special adapter but not worth doing.). Nice, Now get a exrternal LSI sas 6GB controller for your system to hook it up. Do yopu research on the external correct SAS cabling to match your hook ups. Have fun and enjoy! BTW check your PDUs to make sure they are good. If bad, they will ramp up the cooling fans till replaced. heads up
@@leadiususa7394 I'll buy it then. I have a SAS 6gb HBA. I was worried about it needing proprietary stuff. Thank you!
@@leadiususa7394 I got it! Paid about $90 incl shipping and 22 empty caddies. Now I need to get some cables to get it going. Does it need two cables to see all the drives? I have an older SCSI unit with 14 bays and it needs two cables. 7 HDDs appear on each port. Is this the case with this unit?
How do you think about the Dell PowerVault MD 1400?
Well it is a still a SAS disk array so you can't go wrong. But if you want volume go with the 3.5 disk format but if you want high I/O go with the 2.5 drive format with SSD drives. No need for NVMe drives. You will not get the I/O from those drive.
@@leadiususa7394 Thanks for the response!
I am new to some of these server equipment.
Can I, and how do I connect a "Dell EMC 25x 2.5'' SAS SATA SSD Server Hard Drive Disk Array Expansion JBOD Chia" to me, Dell PowerEdge r820?
Get yourself a LSI external dual port SAS 6 GB controller 9200/300 series or better will work. do you research on your cable hook up, it will be a mini-SAS to SAS cable or a SAS to SAS cabling
How about EMC DS60?
If you are talking to the disk expansion array. I have not worked wit those arrays yet but who knows. If a SAS array has the basics SAS setup, you can't miss it up. FC or IP will not so much.
@@leadiususa7394 ok thank you. It has a sas12gbps controller
and what are you going to know! you don't know anything, this information appears to be incomplete! Dislike!
Sorry you feel that way but is nice that you can tell me. Thanks and god bless.
