Question

A vSAN administrator has been asked to increase the usable storage capacity of an existing vSAN cluster to deploy some new virtual machines containing a large amount of data. The details are as follows:

  • Each ESXi host in the vSAN cluster is configured with two disk

groups.

  • Each disk group contains three capacity devices and one cache device.
  • Deduplication and compression are not enabled.
  • Only the default VM storage policy is in use and had not been

changed.

  • Add capacity without re-creating disk groups.

The company would like to minimize the number of devices used for cost Optimization. Which action should the vSAN administrator carry out to provide additional storage to the vSAN cluster?

Options

  • AChanging object space reservation on the default storage policy to 100
  • BAdding new capacity devices to the existing disk groups
  • CDeleting and recreating the current disk groups with a larger disk configuration
  • DCreating a third disk group on each host

Explanation

In order to increase the usable storage capacity of an existing vSAN cluster without re-creating disk groups, the vSAN administrator should add new capacity devices to the existing disk groups. This will allow additional storage to be added to the vSAN cluster while minimizing the number of devices used for cost optimization. https://docs.vmware.com/en/VMware-vSphere/6.6/com.vmware.vsphere.vsan.doc/GUID- 5A5CC5C3-F4C4-4F4D-A6B4-C9A9F36D69FE.html
