Is there an actual use for this in a homelab? Isn't 25gbps enough that no SSD will saturate it?

> While $1100 is not a low number It really is when you're talking 400G. OK there's very few ports on this, but in general if you're looking at 400g interfaces. $1100 won't even get you a genuine Arista 400G passive DAC.

wrs

I haven’t been directly involved in networking for a while, so it was funny to tune back in and see that now not only is 10Gbps apparently no big deal, they even put it on the management interface!

> The exciting part of this is that there are four 400GbE QSFP56-DD ports for a total of 1.6Tbps of network bandwidth. That I can't break down to 10gbit or 1gbit without another switch... > The list price is $1295, but these often sell at a street price of $1100 or so, making this under $0.70/Gbps It doesn't work that way... I like mikrotik, but who is this switch really made for?
