I have a nutanix block with four nodes. I mean four node cluster.
I have a query about fault tolerance. Currently it is set as RF-2
Each node has 6 disks. 4 hdd and 2 SSD
4*800 gb hdd
2* 200 gb sad
OS is AHV.
1) Assume, if one host completely fails, then the vm will be restarted on other host and it will continue to run without any issues.
2) If one disk fails(either HDD or SSD or both at the same time)from first AHV, then there will be no impact.
3) If two disk fails from two hosts(1st AHV and 2nd AHV) at the same time(assume one HDD fails on both the nodes), then what will be the impact for all the running vms in the cluster?
4) If two disk fails from two hosts(1st AHV and 2nd AHV) in different time I. E 30 mins gap(assume one HDD failed in 6AM in first node and another HDD failed at 6.30 AM in second node), then what will be the impact for all the running vms in the cluster?
Could someone please advise?
