VxRail and availability

Jump to solution

Dear expterts,

I have 2 questions about availability.

1. What is the consequence when the SSD disks fails in a node?

2. If one node fails completely, will the replacement be a online event?

If the SSD fails the disk group is associated with is down.  VSAN will operate for another hour and if the drive is not back online or replaced it will begin a rebuild to ensure that the FTT requirements are met.

In the case of a node replacement, obviously it's not an online event for the node you're replacing but the others continue to operate normally.

Hi Franz,

I suggest you to look at the following manual in the UNDERSTANDING EXPECTED FAILURE BEHAVIOR section. It has the answer for those questions.
