In 2024 I would suggest deploying 2x25G instead, via e.g. MCX4121. Pricing is similar (<$30 NICs), but:
* 2x25G throughput is higher than 40G,
* 25G latency is lower than 40G,
* you can use 25G ports as 10G ports, and
* you can use DACs to connect 4x25G <=> 100G
That last point is particularly relevant given the existence of switches like the Mikrotik CRS504, providing 4x100G ports on 25W.
- Palomides 3y agothose are all reasonable points, if I were doing mine again I would spend a little more and go up to 100gbe if you run all older mellanox gear the cx3 can do the kinda nonstandard 56gbe as well
- bombela 3y agoWhat are you doing that you need 100gbe? I am still on 1gbe... I guess I don't transfer anything bigger than a few GiB time to time.
- nickstinemates 3y agoNo individual connection other than like a cr tral storage server needs 100gbe, at least for me, but a 100gbe backplane is good for a lot of 1gbe poe devices as an example. With residential fiber/coax reaching 5gb, 1gb is not enough.
