My, aren’t we testy?i dont need any of those as there is zerto windows in my infra
this will be used for server communication running linux
even when i do setup nfs/san the server and clients will still be linux
so again is the Mellanox ConnectX-4 Dual x 100G a good choice to go with that also supports 40G?
Maybe you’ll never use Samba, but you almost certainly want to use NFSoRDMA. If so, then the cards’ RDMA capabilities are something you need to consider. AFAIK, e810 cards support iWARP, a dying/dead RDMA implementation proprietary to Intel. Mellanox ConnectX-4 cards support RoCE, which is the leading standard and which is being implemented by more and more vendors beyond Mellanox/NVIDIA.
The Mellanox card supports both 40G and RoCE, while the intel card supports
[Edit: I was mistaken: the Intel card indeed supports RoCE V2. Thanks to MountainBofh for the correction].
