To add only individual virtual machines, remove the datastore and click Add VMs instead. Select the VMs to accelerate then click OK.

fvpconfiguration16

The Flash Cluster contains only the selected VMs.

During the configuration of datastores or virtual machines to accelerate, you have to specify the Write Policy. Two options are available:

  • Write Through
  • Write Back
