vSAN
Hello folks,
Do you know of any good vSAN software working with CloudStack?
Thanks

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 client traffic.

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 enough clients, I would guess at least 40 Gbps
network makes sense to leverage couple of NVMe per host/storage node.
Again depends also on client IO requirements as well... Its more an art,
than a science, to make right decision.

How much is minimum bandwidth requirement for storage network in which all
underlying devices are NVMe SSD?

ScaleIO is supposed to be better/more performant...yep.

Fariborz, you also can use ScaleIO exported through iSCSI if you are ok to
go with local storage.
