I have 3 server type 2310 with single ssd,
So if SSD FAIL on 2 different server at the same time what will happening?

If it's a three node cluster and you lose two SSDs the short answer is the cluster will fail. When you loose one SSD, it will rebuild it's stored extents on the other two SSDs to maintain a resilient state. If you lost another SSD, there isn't enough to maintain the cluster resilience all storage I/O will fail because the CVM actually lives on the SSD. The hypervisor lives on the satadom or M.2 drive depending on your generation of hardware. You loose both SSDs and you're not only looking at data loss but complete Storage I/O communication cessation.View original
