Patrick, by now, I think the entire milky-way galaxy knows you like to have a key lessons learned segment. Keep up the great work. It really simplifies the life of the average IT guy.
Absolutely correct
There are other galaxies! Geez, talk about self-centred! 🙄
@@ServeTheHomeVideoj
I just bought six of these to use as storage switches. They're cheap, quick, and they support MLAG so it made them great for the use case with our low server density.
MLAG is great
Yea that is a great use case.
So MLAG isn't affected by the CPU performance issues? Ie you're getting full 25/100Gbps on your MLAG links?
@@Fellhahn MLAG is just a special form of LACP link and is run by the switch chip, not by the CPU. This is true for all Mikrotik devices that support MLAG.
Even on CRS326 switches you can MLAG the 10 Gbit ports and they will still run at full speed and let you "aggregate" across switches. The CPU in those switches is also weak.
@@marcogenovesi8570
This is super interesting to me as I am experiencing issues (i.e. 10-minute random downtimes) after I configured LAGs on my current 1Gbps switch, which I can't troubleshoot at all since the switch only logs "link aggregation group 01 down" with no further debug possible :(
A colleague who manages our Cisco access switches at work recommended me Mikrotik switches (as I'm not going to pay Cisco prices for my home network) and I am looking to buy one (hence watching this video), this MLAG sounds very interesting if it doesn't experience the CPU bottleneck (the LAGs "performance" of my switch when tested with iperf is worse than using single 1Gbps links instead of LACP LAGs).
I have a few questions if you don't mind, please:
Is MLAG only aggregating links going to different switches?
Does MLAG require special support from the device at the other end, on top of the standard LACP support?
And also, does anyone know if the CLI for Mikrotik switches provides any kind of debug info, for troubleshooting random connectivity issues?
Thanks a lot!
Would work great for moving ISOs around my homelab
please be more specific, you mean linux isos, right? right?
@@leitenlexid84 this bad boy can move so many linux distros
How many ISOs do you need?
@@3s0t3r1c Yes
Same with my home videos...
I got one shortly after it came out and I'm extremely happy with it. I was looking for an upgrade from 10G to something faster and the choices were pretty crappy until this popped up in my search results. I'm using it as a desktop switch to connect everything at or near my desk. At the moment, it provides various 40G, 25G, 10G and 1G connections for my workstation, several NAS systems, home office and internet access. It's much more convenient to use the CRS510 rather then the CRS504 for this use case. The slow connections are a bit of a waste of a SFP28 port, but being able to have everything handled by one switch and not needing a second switch was a win in my book.
I've removed the stock fans and the top cover and replaced it with a 3D printed hood in which I've mounted a 120mm Noctua fan that pulls out air directly from the power supply, the switch chip and the SFP cages. The switch is totally fine with the removal of the fans, the fan headers are standard 3-pin and it also doesn't bother that I've just connected one fan at the moment. Before I had the 40G optics in, it temperature controlled the fan and it was mostly off. After the 40G optics went it, the Noctua fan is now on all the time, but you can't hear it, it's basically as quiet as a passive switch.
Great feedback
Hi, can you share the file for the hood? Sounds like a nice mod
What switch is this one replacing?
I want to say thank you for all the hard work you do and all the videos !! YOU GUYS ROCK !! Good work Patrick & Crew !
Thanks!
I am now on my second mikrotik switch in my home lab thanks to your videos ❤
Welcome to the club
nice. as long as you do not plan to have a MLAG setup with MT those switches are a price/performance killer
I have this switch, it works great with various modules, much more options in the settings than your usual managed switch.
Thanks for the awesome review 😊 I’ve got a 510 and 504 in a throughput testlan setup, very happy with them. The 510 is on my desk, replaced the fans with noctua’s to make it less noisy.
Super cool! How are the temps on your optics?
Thanks for the review. Looking forward to 10GbE switches reviews 👍
Working on them today
I got 2 CRS510. I love them.
Awesome!
Nice!! Very jealous!
@@Darkk6969 No need to be. Well I cant use the whole 100Gbit on the QSFP28 Ports because my servers limit me. It is a money sink if you wanna saturate them! 😛
I still love them on a technical level, but in order to really use them in my home lab, I need some more time! :-)
Yep, it's cool how cheap 10/25/100G is for the homelab, while at work getting 1/10GbaseT switches is annoyingly more expensive than 1G. 🙃
10Gbase-T is a power hog
@@marcogenovesi8570 yeah for 10G best to stick with optical or DAC cables
The Aliexpress 10gT switches provide much more value then these for home users.
@@marktackman2886 if you need 25/100G, anything 10g will provide zero value, no matter how cheap it is.
@@marktackman2886 I wouldnt trust a firmware from aliexpress switch
I did the breakout cables on the CRS504 instead. Very happy with it so far, and it gave me a very easy transition from 40GbE.
That is the right answer for many folks
Patrick, I love your content, but please start at least mentioning L3HW offloading on these switches. Many times it's been mentioned that CPU routing on these things leaves nearly everything to be desired. However most of the CRS lineup will also L3 route, wire speed, with no CPU impact with some limitations of course. We use a lot of these switches to build internal BGP fabrics with L3HW offloading enabled, and performance is fantastic in that regard. Yes, what is offloadable does vary a bit switch to switch, but also saying that these things can't route due to CPU performance is also a bit misleading.
We go into that in the main site review
we need more companies that make things like this
Totally agreed.
used to work for an isp that only did mikrotik. they were always way cheaper and better than the competition if you didnt need the support contracts.
Great feedback
we're an ISP in brazil ourselves and we almost exclusively use mikrotik for the same reason, their pricing is very very hard to beat for the features.
Thank you for Showing Amazing Devices which are Beyond from our hands. Please Show Business firewalls with 8+ ports and Open source Networking devices.
ALMOST…. went with this but ended up going with the crs504 4x100gb switch.
It was super cheap and lets me upgrade from SFP28 via breakout cables to full qsfp28 in the future.
The only negative was the cost of the breakout cables 😅😞
Btw I highly recommend a noctua fan swap (at least with the crs504) if you are going to keep it nearby. The fan drone was annoying 😑 but some 3-pin noctuas fixed that in a jiffy 😌
I think a lot of folks will like the CRS504
I do love more options 🙂
About power supplies - do they operate in load sharing or active-standby? is it configurable? would be great to evaluate the thermals if PoE is used and if the fans work less in this scenario (reduced heat dissipation from psu)
Audio was inconsistent in this and the last couple of vids.
Also, would love to see some run-downs of DAC Fan out cables, and also some vendors offerings for programable DAC/Optics
Would also love to see DC power usage info w/o the AC psu's connected for devices that support redundant/DC power in options.
It'd be cool to find a good Layer 3 25-Gig switch for Inter-VLAN routing, non-blocking, hardware offload, all that. This switch would be perfect for single VLAN stuff for the server VLAN or main internal LAN but need something as a core Layer 3 homelab switch right before hitting the edge gateway/router.
Great stuff as always STH, Keen to see a review on the new QNAP QSW-M7308R-4X as a competitor to this
Would be great if they released a 16 x QSFP28 port model.
And here I was hoping they would make an 8-port * 100gig model…was a big ask🤣🤣🤣🤣
You want a 16-port version….i would buy it if they did😎
why stop at 16x, why not 48x
he ain't gonna buy one anyway.
@@marcogenovesi8570 cost would be the main factor. That’s why I would prefer an 8-port…when you factor in cost and economies of scale….the difference in price may be negligible…but it always depends on if they want to pass on some of those savings to the consumer.
@@mikealthomas1 the switch chip for an 8 port is bigger and more expensive. I doubt Marvell prices bigger chips in a way that makes that more convenient
Your talk about the underperforming processor... Does that include vlan and qos?
VLAN and QoS is handled by switch chip, not CPU
How deep is the packet buffer? Ran into issues with their 10G models going down to 1G with network video.
Does the fan control under System > Health work properly with custom PWM percentage settings?
Have a few different MikroTik switches and for example the CRS312-4C+8XG-RM ignores custom settings which leads to the known “fans-are-off-for-a-while-and-then-they-ramp-up-annoyingly-loud” cycles like on many/all other MikroTik switches that have fans. Many models can avoid this by increasing the default minimum fan speed from 0 % to something like 15 %, preventing the heat soaking of the switches while still staying pretty quiet.
I’ve got a set of these switches and the fans work like they should. There were some changes around the fans in routeros lately, update to 7.14 and see what happens.
I just bought one of these the other day after watching your CRS504 review. I think another thing to note is that the Mikrotik switches not only support the standards-compliant backward compatibility with SFP+, but they actually support SFP too. It really simplifies your cabling situation if you're going to have to use breakouts on the 504.
Watching some other reviewers they have a similar homelab setup to me: 1 workstation, 1 fast storage array somewhere else, and then you need to uplink this thing to your core switch (or make it your core switch). So they end up using SFP+ to join their L2 at 10G but the QSFP28 is purely just to get two hosts talking from across the house/workspace.
On a totally separate technical note, having watched a few of your recent reviews, I hear this weird flanger effect in the highs in your audio, particularly with speech. I'm listening on Adam A7X studio monitors and hear it also in my HD599's. I don't know if it's a de-esser acting up, phase issues between mics (maybe you have a lav + room mic out of phase?), or some kind of AI noise reducer? I hear this in other videos sometimes and imagine I'm crazy but I sent it to an audio engineer friend just now who says he hears it too.
Strange. Sennheiser MKH-416 on the sitting set and DPA 4061 or 4071 on the standing one, but only one mic per. We do need to get someone to work on audio. These are straight out of mic.
Just wondering - Does your audio engineer friend think they could create a profile to fix? I want to hire someone to make our sound comes out better on both sets. Right now, everything is unprocessed so it would probably be good to have presets for both sets that I can have our editors drop on. If they think they can do it have them shoot me a note at patrick at servethehome
@@ServeTheHomeVideo Just messaged him. Hell shoot you an email!
The reason why I have to select this router instead of the other 4x100GB is that to my rack I get only 10GB uplink, how could I insert it to the 4x100GB switch? So this is my choise MikroTik CRS510-8XS-2XQ-IN
About power consumption without attachments - that is more like without plunged in devices that consume power. Passive/Short DACs don't consume noticeable power.
MikroTik….please make an 8 port * 100GB switch!!!!
The 4-Port is good…but an 8-Port would be awesome😎😎😎😎.
Optional/Nice to have: more processor power.
Or do 2 versions:
1. An 8-port version, which will need a better processor and more memory(basically the 4-port * 100GB upgrade)
&
2. A proper 8-port with a good processor and memory to do routing/switching.
More expensive switch chip sadly :-/
I am going to strongly disagree with you on the more processing power.
Its a switch, use it as such. If you want a router then buy one, Mikrotik themselves already have beasts on that front. Look at the block diagram on Mikrotik's site (Its under support and downloads) the connection between the switch chip and the central CPU is just 1Gbps so throwing more CPU at it would really be pointless if a single core is already reaching about half the capacity of that link.
@@ServeTheHomeVideo yeah, I think if it goes above 8-port(16 port sounds good…but the cost) the cost may be a bit crazy. And once it goes over $2.5k…then people will start considering the used market for data center switches.
However, if we don’t show MikroTik that we would like higher port switches…they wouldn’t know.
It depends on “demand” and if it then makes economical/business sense to “supply”.
What's the use case for 8x 25G or 4x 100G ports? Wouldn't you at those speeds need at least 24-48 ports?
What if you have a smaller setup? Like an office, store, or whatever?
24-48 100Gb ports? Are you running a whole datacenter?
To move things faster, let me tell you flinging around a 500gb VM on 1gbps really makes you think hard about shutting down the whole server and juggle drives around instead.
Do these support RocE? And PTP? It’s hard to find this info.
no
noob networker question, if your opensense router is controlling dhcp/vlans do you still need to manage them at switch level or is that only to control say port 2 tied to x vlan thing.
Somebody correct me if I get this wrong in regards to your scenario...if opensense is controlling VLANs and DHCP,
you still need to configure other switches to support the VLANs on their ports for them to function properly because once traffic hits the switch and if no vlans are configured it will consider any traffic as untagged and associate it with the default vlan, vlan 1
You need to set in the switch what ports go on what VLAN. This is what all managed switches are for
I barely have the need for 10GbE. My train of thought is if you need 10GbE and don't have a team of users accessing the data, you use more local storage. My current system has 12TB of NVME storage (3x4). However, with how cheap some of this 25gig and 100gig gear is getting I might as well..... right? lol
poe to power the switch? wow. so is it safe to assume this switch expects you to already have another switch which is Poe+ so that would then power this other switch filled to the brim with sfp+ ports?
You can dead end a poe power injector. Then run a cat 6 to power the switch in some remote area without needing to higher an electrician or drape up extension cords. In some places half the lighting runs off POE these days just because hiring the IT guy is far cheaper than hiring an electrician.
I wish the videos would start with the pricerange so I know if I want to keep watching
We put an entire section on pricing List v. Street and so forth.
Anyone know if these would be compatible with SMPTE 2110 IP Video, this could be a game changer paired with blackmagic’s recent IP announcements
I’d like to know as well 😊I think it must have RocE support
SMPTE 2110 IP is just UDP under the hood, no fancy routing or anything, should work just fine.
@@zyxwvutsrqponmlkh but usually it would require rdma style transfer afaik for efficiency, maybe also PTP for camera sync. Hence my uncertainty
Spend more money on optics/NICs than you would on the switch.
That is very possible with this.
(laughing in DAC cables)
@@marcogenovesi8570 People don't understand that they should only use optics for long range installs. If your machines are all in the same rack as your switch then you should use DACs.
@@mohammedgoderPeople are silly. But I was using a 1 meter fiber cable to connect my PC to a Mikrotik switch. Because a DAC didn't work and the switch didn't like my NIC. Until it was fixed in a firmware update.
@@timramich I feel that pain.
Intel NICs up until their 10G line were all locked. So you could only use Intel optics unless you did some firmware hacking (I may or may not have done such a thing). I don't know if that also applied to DACs or if it was just optics. Regardless there is a way to unlock them.
My upgraded TrueNAS reads at 7.5GB/s and writes at 3.2GB/s. I NEED THIS :|
Yes.
Yes I really need a $1k switch in my home network.
I was all stoked at 15 watts then I saw the price 😢
Sure but if you want 25GbE and 100GbE you are spending a lot on NICs and optics already
You say that about mikrotik pricing, but I still can’t find a good deal on a crs305
Doubleradius has them in stock at MSRP. Just got a couple the other day. Streakwave ships faster but they are out right now.
So, if you use both the QSFP28 ports, you cant use any of the SFP28 ports? Is that right?
nope
No. You can even break the QSFP28 ports into 4x SFP28 ports and get more 25GbE if you want.
i really wish, mikrotik would offer switchOS for lineups like this, or - for this instance - for all switches from which you don't expect much L3-capabilities. it would lower the entry-barrier sooo much, and let's be honest: RouterOS is way overkill and overcomplicated for just switching-needs.
That is very fair.
A bit expensive for home. They could do two barrel jack inputs instead of these custom psus, they cost a fortune.
That is probably correct. Or do 1 AC and 1 DC for redundancy.
@@ServeTheHomeVideo POE only :P
I swear they are going to put a solar panel on one and some 18650 batteries inside something one of these days.
@@zyxwvutsrqponmlkh Redundancy on POE should be possible too :)
@@Cowayger It tis. Google, POE splitter or PEO extractor.
Is 25Gb NIC really cheap? Not sure about that statement.

Nvidia connectx6 - 500$.
Connectx4 25Gb also exist and are cheap

@@MultiKylieminogue from where? i have been trying to find cheap used nics with dual sfp28 ports but the cheapest i found was $200 CAD on ebay :c
Plenty of sub $40 USD ConnectX-4 LX on ebay.
ConnectX-4 Lx on ebay can usually be had for like $30-40 these days.
Nah, with bugs around and general indolence about introducing industry standards I made mistake of buying mikrotik once. While it is a fun toy for home lab, SMBs will struggle and small enterprises will feel lack of features every other brand (including Ubiquiti) has for many years
5 power inputs, you can power your 100gb switch off POE... Because reasons. I swear this is going to be shoved up in the ceiling tiles somewhere and the new guy is going to really be scratching his head at how this monster of a mini switch is running with no obvious power supply.
Also, classic Mikrotik to pare a $300 switch chip with a $3 CPU. Leave everything unlocked in software but kneecap the hardware enough to force people to buy the router versions for a lot of use cases, when $20 more in CPU and ram would have made a product substantially more versatile.
A a typical 20 dollar cpu would not have enough pci lanes or network interfaces included to make this a good router. I’m glad they make dedicated switches with simple cpus and dedicated routers with complex cpus.
@@stephanszarafinski9001 This switch chip has an unused pcie lane and 2 more unexposed 25gbps interfaces. They are only talking to it via 1gbps.
do not ever bridge ether1 to one of the (q)sfp ports to avoid software bridging and take advantage of the marvell instead.
and do not plan any sophisticated L3 stuff on those. at top most some basic inter-vlan-routing but nothing further and you're good to go with it for what it is ... a SWITCH
Yes. The management port is on the Qualcomm not the Marvell chip
@@ServeTheHomeVideo yep, i know. working with mikrotik for about 10 years now ;)
Such a nice router!
Switch not router
Cheap, $825.
About $2/Gbps. If you need high speed, this is cheap
As a network engineer I am going to price this differently. I do not think this is worth $800-$1000 for a home user. This is a $500 device. The DC power/redundancy feels like trickery to inflate the price.
It's cheaper than pretty much everything else in its class, what makes you say it's "not worth X"
@@marcogenovesi8570 because its bottom of the barrel in its class, the price premium is not there with this amount of ports and class of chip
You call that cheap??!
I thought this was "Serve the Home" not "Serve the Enterprise Data Centre"!!
Huh? I mean first off, STH is the largest enterprise DC review site (and has been for many years. We have reviewed 8x GPU servers since 2017, blade GPU servers since 2016. Very strange comment. Second, compared to other 100GbE switches, this is cheap upfront and even cheaper to run. Check out our other 25GbE and 100GbE switch review video from vendors other than MikroTik like Dell and so forth.
yeah, have you seen the prices of other switches with similar features? Now you probably don't need it in your home but the review isn't wrong
