You can set up a virtual flash resource or add capacity to existing virtual flash resource.

About this task

To set up a virtual flash resource you use a solid-state disk (SSD) connected to your host. To increase the capacity of your virtual flash resource, you can add more SSDs, up to a total of eight. An individual SSD must be exclusively allocated to a virtual flash resource and cannot be shared with any other vSphere service, such as Virtual SAN.

Procedure

  1. In the vSphere Web Client, navigate to the host.
  2. Click the Manage tab and click Settings.
  3. Under Virtual Flash, select Virtual Flash Resource Management and click Add Capacity.
  4. From the list of available SSDs, select one or more SSDs to use for virtual flash and click OK.

Results

The virtual flash resource is created. The Device Backing area lists all SSDs that you use for the virtual flash resource.

What to do next

You can use the virtual flash resource for cache configuration on the host and Flash Read Cache configuration on virtual disks. You can increase the capacity by adding more SSDs to the virtual flash resource.
