100Gb ports can usually be broken down to 4*25Gb or 2*50Gb or 40Gb/100Gb, you don't really need 48 physical ports and it's more flexible.
I have Arista DCS-7060CX-32S-F, it's great.
May I ask you if you have faced this issue? Let's say I want to link older X710-DA4 4xSFP+ card to this Arista, what's my best option?
Should I set it to 40G and may use:
Intel | Intel® Ethernet QSFP+ Breakout Cable | X4DACBL3 | 920347 | 606760003 | QSFP+ to (4) SFP+ Direct Attach |
Or it's not gonna work from switch side and I need:
Intel | Intel® Ethernet QSFP28 to SFP28 Twinaxial Breakout | XXV4DACBL2M | 952303 | NDAQGF-I202 | 100GbE/4x25GbE/4x10GbE Direct Attach |
But set port as 4x25G operating in 4x10G mode, will it be accepted by NIC? As 100G breakout isn't listed in Intel® Product Compatibility Tool for X710-DA4, but for 2x25G XXV710-DA1/DA2
And what about single 40G XL710-QDA1 - will it work with regular QSFP twinax?
P.S. We're close to stick even with
MikroTik due to it's baldness and three times lower price for a new one, as technically it's more than enough for our case, yet a bit afraid of newness and no positive feedback from Mtik course trainers
