Installing, Configuring, and Setup

An organization needs to configure a new storage policy with these requirements:

  • Failures to tolerate = FTT 1/RAID-5 (Erasure Coding)
  • Number of disk stripes per object = 8
  • IOPS limit for object = 0
  • Object Space Reservation = Thin provisioning
  • Flash read cache reservation = 0%
  • Disable object checksum = No
  • Force provisioning = No

The administrator creates the policy through storage-policy-based management and assigns it to a 100GB virtual machine on a four-node vSAN OSA cluster to test the results of the new storage policy.

How many components per host will be created for the virtual machine's storage objects on the vSAN datastore?

  • A 1
  • B 2
  • C 8
  • D 32
Explanation

For vSAN OSA, RAID-5 with FTT=1 is a 3+1 layout: three data components plus one parity component across four hosts. A stripe width of 8 creates eight such stripes. Because each stripe places one component on every host in the four-host cluster, each host contains 8 components.
