QuestionQ126

Installing, Configuring, and Setup

A vSAN administrator is enabling deduplication and compression on a vSAN OSA all-flash cluster and wants the VMs to stay operational.

The details are as follows:

  • The vSAN OSA cluster has 4 nodes.
  • Existing VMs use a RAID-5 storage policy.

Which action should the vSAN administrator take to achieve this goal?

  • A Use the Allow Reduced Redundancy option
  • B Enable TRIM/UNMAP
  • C Use explicit fault domains
  • D Change the existing VM storage policy to RAID-6
Explanation

Enabling deduplication and compression on vSAN OSA reformats disk groups and evacuates their data. In a four-node cluster with RAID-5 objects, maintaining full RAID-5 redundancy during that evacuation can be impossible because all four nodes are required for the stripe. Allow Reduced Redundancy keeps objects accessible and VMs operational while temporarily reducing their protection level; full policy compliance is restored after the format conversion completes.
