[@satoshimanabe2493]

@@MrMartinSchou By that argument, there's also no need to actually have two management ports. This switch has some pretty beefy RAM and FLASH compared to other switches, so there's a bunch of things you can do with the management ports. Anything that has to pass data through the CPU could potentially work on it, even routing. But I think my favorite answer would be "because the CPU supports it." In contrast, I have a CRS-518-16G-2S+IN, which uses a Wi-Fi SOC for its CPU...but it doesn't have Wi-Fi. Would be fun if they added the features supported by the SoC.

I think this is pretty nice option for many small businesses, which want to have new switch with ability to upgrade servers down the road in next 1-2 years to use 100Gbps for CEPH for example. I think even i could use it for 2-3 server cluster with CEPH under proxmox (yeah, 2 servers for quorum is great idea /s), so that i would still have 10 ports left for other stuff down the road (and most likely get another one to have HA after some time). Even "cheap" Supermicro servers with U.2 slots can be bought new for like 15-18k, which easily could hit stable 12GBps or more, so price-wise i think it have everything what users would need - like You said. 2k is a bargain for me.

[@marcogenovesi8570]

You can use 2 servers + Qdevice so it has quorum for Proxmox (but not Ceph), and with just two nodes you are better off with zfs and replication or even the linbit drbd block device replication than Ceph. At least imho

Of course this is a usecase that you will almost never see in the wild (As it is pretty stupid), But even with 2-3 editors in a reasonable use case you could saturate a QSFP28 port.

i am still looking for an afordable vlan/trunk switch with at least 8 downstream ports 1gig and one uplink port of at least 2.5 gig.. any suggestions?

[@39zack]

CRS310-8G+2S+IN ?

[@LakeZern]

Can you please check its speed with NICs supporting iwarp instead of Roce.

[@BattousaiHBr]

still no word on the size of the TCAM? their L3HW help page still doesn't list this switch.

[@RockTheCage55]

cheap it is but well beyond my price point for a switch.....that is for sure.

[@ServeTheHomeVideo]

That is fair. I think for a lot of folks who need/want this much 100GbE they will think this is cheap. 100GbE NICs, optics, DACs and more can be costly.

[@MoraFermi]

I wonder what kind of support these things have for redundant or “virtual chassis” type setups. Having dual path configuration, even if it’s active/standby is rather critical.

[@marcogenovesi8570]

They support bonding, LACP for basic failover/bonding and MLAG for using two switches as redundant with bonding

[@christianponopp8756]

The SFP´s will make it expensive :D

[@ServeTheHomeVideo]

I mean you can get SR optics for under $60 new

[@marcogenovesi8570]

SFPs make everything expensive

[@cjchico]

No RDMA/DCB? C'mon Mikrotik

[@AnIdiotAboard_]

The day is coming when home users get hardware of this quality. Id love to have 100 gig networking at home, i really would, i already have 10GE and GF, and its here ill be stuck for a long as time, cos nothing above comes with a god damn ethernet uplink port anymore, i might have 2.5 Gb internet, but i have a poxy stupid fiber setup they have used, with transceivers you cant remove and only 1 2.5GB Ethernet out port. I can only sit and prey

[@deepspacecow2644]

By ethernet do you mean rj45?

[@AlpineTheHusky]

I just half switched to 2.5gig....what the hell is going on

[@LiLBitsDK]

can we get a "smaller" one with like 4x 100gbit and 8x 10/25gbit? :D

[@ServeTheHomeVideo]

Check the links below for the CRS504, CRS512 and so forth

[@ServeTheHomeVideo]

Check the links below for the CRS504, CRS512 and so forth

[@LiLBitsDK]

@@ServeTheHomeVideo cheers much appreciated

[@sparkyenergia]

Does 100gbe behave like a link aggregation of 25gbe? If it does then you cant get a single file transfer going between systems at 100gb it will only be good for 25gb. Is that true or false?

[@wiziek]

why are you trolling?

[@mvs3246]

No, it does not. You get a single 100GbE link unless you split qsfp port intentionally.

[@sparkyenergia]

@@mvs3246 Nice. Thanks. Now that makes it an interesting choice between the 4*100gbe mikrotik or the 16*25gbe mikrotik switch for me.

[@itsLaUziCuh]

Can you please review this cheap switch Xiaomi Mi 10G Ethernet Switch Has 2 sfp + ports and rest 2.5gb

[@win7best]

that thing costs more then my server xd

[@davelamont]

Is it backwards compatible to 2.5 gig? LOL

[@ServeTheHomeVideo]

Ha!

[@sloppycee]

100 GB/s is faster than an Intel Core X memory bus... and we are very close to Terrabit Ethernet. I don't get it. We need an open source consumer mainframe OS

[@ServeTheHomeVideo]

1.6Tbps Ethernet will be deployed in 2027. We just did a video on a 64-port 800GbE Marvell switch two weeks ago. 800GbE would require a PCIe Gen6 x16 NIC just to handle a single port.

[@DenofLore]

Motherf*** I literally just got the last piece for my 10g homelab in. F*** right off with this bullshit 😢

[@SoraIroNaKISEKI]

😂😂 First? The vibe couple months ago was the best 2.5G switch and now we are talking in 100G.

[@ServeTheHomeVideo]

I mean last week we did 800GbE :)

[@boneappletee6416]

​@@ServeTheHomeVideo honestly all these speeds make me giddy

[@michaelgleason4791]

This channel really needs to change its name. Homelabbers aren't looking to spend 2 fucking grand on a switch.

[@ServeTheHomeVideo]

The term homelabber came after STH which has been around for 15+ years at this point. It has been the largest server, storage, and networking review site for around a decade. Most of the folks getting into homelabbing are doing so to learn things for work. For even a small business this is cheap, and we had an example of that in this video

[@twoina]

Our last firmware update downgraded random ports to 10 or 100 mbps tx. It took some time to get a fix. Mikrotik lost some of my trust with this

[@bober1019]

sfp/+ switches were ALWAYS affordable. it's the transceivers that do the work/cost alot. but the knock off brands do fine for home use. carry on, nothing new here.

[@kchiem]

"100 gig networking is not even fast anymore"

[@robgronsky4466]

Its fast enough unless your a hyperscaler.

[@platin2148]

I still didn't get a switch with enough POE++'es and SFP's so no need for 100 gig..

[@ServeTheHomeVideo]

We have the new CRS320 review recorded. It will go live in Aug

[@PedanticTwit]

You know what would get me to buy Mikrotik hardware again? Not having to use RouterOS with it. Seriously, to _hell_ with that. It's more of a pain than nftables.

[@stephanszarafinski9001]

That would be a waste, MT finally made a switch that can be a router too. So with routeros on it, you can set up the 10gbit ports as internetconnection (two connections, so dual wan is possible too), use the fast cpu as a router and have it directly providing fast internet to all your devices on the switch!

[@PedanticTwit]

@@stephanszarafinski9001 You can already do that with several Mikrotik switches, such as the crs312-4c+8xg-rm. The thing is that would suck because RouterOS sucks. It would be one thing if you could just run OPN- or PFsense on the device, but you can't. You're stuck with the horrible, sweaty ass that is RouterOS, which would mean missing basic functionality like DNSSEC support. And yes, you can always run a separate DNS server, but if you're doing that, you might run a separate router and firewall, too, making RouterOS even more pointless and unnecessary and shit. I used a Mikrotik switch as a distribution switch for a year. It was a constant headache and source of anxiety. Moving it downstream into purely an access role in a completely trusted environment where it can basically be a dumb switch was such a relief.

[@katjaczajkov8694]

around 2.460,80 EUR are not cheat, cheat is realated to around 100-400EUR or $.

[@ServeTheHomeVideo]

There are sellers with these under 2,000 EUR. For this class of switch that is cheap

[@eW0LF]

Nothing to see here since it doesn't have usable OS. Roce/rdma, MLAG et. not working or non existent. Good hardware, but's about it.

[@actckactck2042]

Although I bought the crs520, I still couldn't accept the code quality of the mikrotik team after repeated consideration. So I sold it without even unboxing it.

[@eW0LF]

@actckactck2042 and that is the reason I went for other vendors. Either used or new, they are better than Mikrotik.

[@Zecko19]

Yet any decent managed 10G switch with 10+ ports costs 50% of this in 2024 ... 🤮

[@ServeTheHomeVideo]

Yea. The challenge with 10GbE is that it is now so slow that it gets very little investment by companies for new chips. Many of the Realtek switches we are seeing were designed for things like automotive

[@kelownatechkid]

I cannot imagine shelling out 3 grand CAD for a microtik device, I am sorry but I'd take any used appliance from another company over that lol

[@chriswright8074]

Why would anyone need a 100 gig

[@jerry1333]

Since when small office need 16 x 100GbE ?! we can barely get 1 Gbe Wan connection and all our pc run 1GbE

[@ServeTheHomeVideo]

I mentioned the story in the video about someone who recognized me in LA as the MikroTik Guy that wanted to know about this switch. He has a video production studio and needs a dozen 100GbE links for editors plus a few more for storage.

[@robgronsky4466]

There are desktop and workstation motherboards with 10Gbps ethernet and pcie lanes supporting 25, 40, and 100Gbps on the consumer market. Its a bit of a trade off between storage, networking, and gpu but I love my MSI x670e ace.

Okay... I think cheap might be a bit of a stretch. Affordable, sure, but not cheap 😂

[@Cooper3312000]

Lost me at $2,000 lol. I'm cheap when I see cheap I think $100 or less.

[@deimosian]

Cheap? LOL, I got a Questone2 for $160
