• Cache Full Warning Threshold — Defines the percentage of cache space used
that will trigger warning messages to the system event log.
• Begin Deleting Images — Defines the percentage of cache space used that will
trigger automatic deletion of the oldest persistent images with the lowest
retention weight on the system. Automatic persistent image deletions are recorded
in the system log.
• Cache Size — Specifies the percentage of the volume that is allocated to the
cache file. Increasing this value will allow more and larger persistent images to be
maintained. Ensure that adequate space is available on the persistent image files
