QuestionQ61

Performance-tuning, Optimization, and Upgrades

A three-node vSAN OSA cluster supporting a business-critical, I/O-intensive workload is running out of capacity. Each host has five disk groups, with four capacity disks in each disk group. The administrator needs to increase the vSAN datastore capacity as soon as possible.

What should the administrator do?

  • A Enable Deduplication and Compression on the cluster level
  • B Add additional capacity by adding a disk on one host and creating a storage pool
  • C Add additional capacity by adding a vSAN ReadyNode to the cluster
  • D Add additional capacity disks to each disk group
Explanation

vSAN OSA supports up to five disk groups per host and up to seven capacity devices per disk group. Since every host already has five disk groups but each group has only four capacity disks, adding capacity disks to the existing disk groups directly increases datastore capacity without waiting to deploy and add another host.
