Ceph storage and Mellanox 40/56G

[anona]

Hello,
Does proxmox support Mellanox 40/56Gbps NIC.
Want to connect 3+ node each of dual cpu, 128gig ram and 120gb ssd for proxmox which will be connected to Ceph storage with 24x SSD.
Is there any redundancy option for Ceph storage in case if one storage fails it switch to secondary storage?
Can we scale the solution by adding nodes and storage on the fly?
Thanks in advance.

I think you should call out Connect-x Version, and possibly the Mellanox Card numbers. Ive been trying to get OFED and some older Mellanox Infinihost III versions, pre connect-x 3, connect-x 4, connect-x 5 and no luck getting drivers recognized. You can ping me if you want my tech lead to build drivers if the source is avaialble and you need drivers.

no, you need to use bonding

yes, sure, you can grow or reduce the cluster on the fly.
