VMware vSAN Platform and Architecture

Question

A customer has deployed a new vSAN Cluster with the following configuration:

  • 6 x vSAN ReadyNodes
  • All Flash
  • 12 TB Raw Storage

vSAN 8 is deployed with ESA. VMs are configured with a RAID-5 VM policy. During failure testing, before the new platform is placed into production one of the ESXi hosts is made unavailable. Which RAID-5 data placement schemes will vSAN use with this failure condition?

Options

  • AvSAN can protect the platform using adaptive RAID 5 if the ESXi host fails to return
  • BVMware HA will migrate the storage objects to another node in the cluster
  • CSome VM data will be unavailable until the failed ESXi host is recovered
  • DThe data components on the hosts will be marked as degraded
