Most people forget that it’s not the sequential performance that counts.. it’s
the 4K random performance and even for NVMe-SSD’s, a redundant 10G connection
between the hosts will be absolutely sufficient.
However split it up in pairs so the one pair takes care of ceph/vsan, the other
of the
Well, that requires some math I guess, but certainly not less than 10Gbps...
You need to be aware of client vs replication traffic between storage nodes
(hosts, whatever) and do some math...
With single NVMe, being able to push 1GB/s at minimum = 8 Gbps ( 8Gbps per
single NVMe device)...and
