Setting the cache state for virtual machines and disks
For the contents of a virtual disk to be cached, you must enable caching on both the disk and the virtual machine on which the disk is configured. The
cache state
determines whether caching is enabled or disabled for a VM or disk.
Note:
It is important to understand the difference between the cache state and the operational status of the cache. "Operational status" refers to the health of the cache on a host, VM, or disk, and can be affected by factors other than the cache state. The cache state for a VM and disk may be enabled, for example, but caching still may not be available because the cache space has not been allocated or formatted.

Viewing the cache state
A green status icon for a virtual machine or disk always indicates that caching is enabled. You can also view the cache state for a VM or disk on its details page.
Enabling caching
For the contents of a virtual disk to be cached, you must enable caching on both the disk and the virtual machine on which the disk is configured. You can enable caching on as many disks on a virtual machine as you want, but you must enable it on at least one disk for caching to be performed.
Disabling caching
You can disable caching globally, by disabling caching on the virtual machine, or locally, by disabling caching for individual disks on the virtual machine.
