The operational status of the cache refers to the health of the cache on a host, virtual machine, or disk. The factors that determine cache health depend on the resource: for a VM, whether caching is enabled, whether cache space has been allocated, and so on. A green status icon for a host, virtual machine, or disk always indicates operational health.
The operational status value indicates the current operating status of the cache for a virtual machine or disk. The status of a disk, for example, may be set to Degraded when cache operations show high latency in periods of extremely heavy read and write activity. After cache operations return to normal latency readings, the disk operational status is set back to Normal.
The operational status icons displayed in the Flash Accel Management Console show the status of hosts, virtual machines, and disks. The icons should be green for all devices caching data.
