After you enable
the video caching feature, the appliance starts caching videos from the
configured video sources. The status of disk usage is depicted in the Cache
Disk Usage graph on the Global Settings tab of the Video Caching page, as shown
in the following screen shot.
Note: The appliance
uses 10% of the allocated disk space for management purposes. When the disk
usage reaches 90% of the allocated disk space, that is an indication of the
disk being full. To cache more video objects, the appliance removes the least
used objects from the video cache. You need not clear the cache unless the
cache serves stale video objects.
