When Virtual SAN is enabled in manual mode for the host cluster, you can manually combine specific cache devices with specific capacity devices to define disk groups on a particular host.

In this method, you manually select devices to create disk groups for each host and add at least one capacity device and one cache device to each disk group.


  1. Navigate to the Virtual SAN cluster in the vSphere Web Client.
  2. Click the Configure tab.
  3. Under Virtual SAN, click Disk Management.
  4. Select the host and click the Create a new disk group icon ().
    • Select the flash device to be used for cache.
    • From the Capacity type drop-down menu, select the type of capacity disks to use, depending on the type of disk group you want to create (HDD for hybrid or Flash for all-flash).
    • Select the devices you want to use for capacity.
  5. Click OK.


The new disk group appears in the list.
