ARISTA DCS-7050SX-64 R going for US$125.00 | EBay

[tinfoil3d]

I have the 40g version of 7050 family, they can be pretty noisy but they're okay with 30% speed(still a little bit of high frequency)
Hard for me to compare now as i moved everything in the rack in a dedicated room so i don't know how loud it is anymore. Everything is super loud there.
idr, i think it was "environment fan override 30" or something among the lines, autocomplete will help you with this
These were ~300 USD half a year ago at their website. Again, from my experience, "dedicated networks" were reliable.

does the fan control command also control the PSU fans or are those pretty quiet as is?

They all comply with the set speed, but PSUs take a little longer to change speed. Otherwise afair it was pretty quiet. I can't distinguish any sounds right now, i can only confirm that my cli shows they all change together when i do fan-speed override.

Well now for some thread necromancy, but I think it might be appropriate. These switches are still out there and still a deal

I just got one of these myself. I understand that third party SFP+ are probably not supported by default. I also understand that the old method of putting the enable3px file in the root of the flash doesn't enable them either. Is there a known workaround aside from knowing someone at Arista who might give you an unlock code?

And how do you know if a transceiver is unsupported? I tried one and it shows as errdisabled but I don't know the reason why - it could be something else I guess.

Running 4.28.9M on it, which is the highest version in the 4.28 train I could find in the wild.

 

[lamune]

Thanks all - got the transceiver issue sorted out.

How? please write here, so we will know.

 

[BobTB]

Do these switches need some licensing to allow all the features?

 

[ano]

no

 

[lamune]

Here's what I learned. Arista will give you a key to override the module detection if you have a valid support contract, or maybe ask them nicely I guess. The format of this config command is:

service unsupported-transceiver name key

so it would look something like

service unsupported-transceiver sthforums 1a2b3c4d

Since it's a licensed thing probably best to not share it however if you were to search the internet for that command you might find something.

Probably not a bad idea to also add this:

errdisable recovery cause xcvr-unsupported

you also can avoid the need to reboot the switch after entering the commands (and saving them to running-config) by doing this to restart the related service:

bash sudo kill -9 XcvrAgent

If it's done correctly your transceivers will come out of errdisabled

can you run SoNIC on this switch?, otherwise, are the Arista firmware upgrades freely available?

EOS images are not publicly available for download without a support contact. There is a thread here, however, where people who are looking for such things can make it known, and…

The price on these sure has gone up since I bought mine.

No, SoNIC is not supported on this hardware. It'll boot, but has no drivers for the switch chips on it.

I am told by one vendor that is the lack of PSU that have push the prices so high.

Thanks. It seems the cheapest alternative is DCS-7050QX-32 for around usd 300.

I implemented an Arista DCS-7050SX-64-R late last year, and my experiences:

1. I have 1 server connected vis 2M DAC/Twinax cables - SFP+ ports to Broadcom BCM57810 2P cards, and 10G Copper SFP+ modules to X540-AT2 LOM adapters (not precisely supported for Hyper-V on Windows Server 2022)
2. I have 2 other servers connected via DAC/Twinax cables to 4P intel X710 CNA adapters and 1 server with (1) Broadcom BCM57810 2P card and (1) 2P X710 CNA card.
   1. on the X710 ports, I am having trouble getting the ports to connect on the switch after reboot, I have to explicitly set the Speed/Duplex on the network card to 10GBps. I might need better DAC cables for this).
   2. I do not have this problem on the Broadcom cards, but have a little instability with Hyper-V VMs that I have yet to track down.
3. The Uplink to the house network is a Cat6E cable across my garage to a Buffalo 8P Multigig Switch, using a SFP+ Copper module.I initially tried a generic Copper 10 G Module, but the switch did not support it. I had to go to FS.COM and buy an "Arista approved" module, which cost 30% more than the generic module (and nullified the existing modules that I was using on cards and another SFP+ port switch), costing an additional $300+ expense but work just fine.

I am still trying to enable some of the more advanced features like 802.1Q VLAN and LACP port aggregation, but my other devices have limited support for these capabilities, so I will have to upgrade those later. Overall, I am happy with the switch.

i really want one of these to simplify my switching infrastructure and just get countless 10gbe ports, and i love the ability to adjust the fan speed in the CLI, but has anyone compared the fan noise to the ICX7250 models? i do like those switches but theyre too loud. louder than everything in my rack even with slightly slower fans

I don't own an ICX7250 or know how loud or quiet they are. I do own several Arista 7050's, and they are not quiet switches - they are data center grade switches where noise is not a concern. Turning down the fan speed in the CLI helps a lot, but if you want silent or very low noise you're not going to be happy with them.

these aristas are in another league fan noise wise than the little 7250s lol. you're talking about ~180w of idle load heat to dissipate versus 50
