A customer has deployed a new vSAN cluster with the following configuration:
5 x vSAN ReadyNodes
All Flash -
12 TB Raw Storage
vSAN 8 is deployed with ESA.
New VMs are configured with a RAID-5 VM policy.
Which statement is accurate?

Which statement is accurate?
Given a vSAN 8 cluster with 5 hosts and a RAID-5 VM policy, the correct data placement scheme is a 2+1 RAID-5 configuration. This setup involves using two data components and one parity component, which is appropriate for clusters with 3 to 5 hosts. Thus, vSAN will use a 2+1 RAID-5 data placement scheme with parity.

For 3-5 hosts, the 2.1 RAID-5 data placement will be used. B : RAID-5 does not provide FTT=2 protection. For that, it will be RAID-6 (an it needs more hosts) C : It needs at least 6 hosts for 4+1 data placement. D : well, noooo
Starting with vSAN 8.0 ESA (Express Storage Architecture) VMware has introduced an adaptive RAID-5 mechanism. What does this mean? Essentially, vSAN deploys a particular RAID-5 configuration depending on the size of the cluster! There are two options, let’s list them out and discuss them individually. RAID-5, 2+1, 3-5 hosts RAID-5, 4+1, 6 hosts or more As mentioned in the above list, depending on the cluster size, you will see a particular RAID-5 configuration. Clusters of up to 5 hosts will see a 2+1 configuration when RAID-5 is selected.
