Component

Description

Archiver

Software that automatically copies online disk cache files to archive media, such as to a disk or a tape.

Releaser

Software that automatically maintains the online disk cache of an archiving file system by freeing disk blocks occupied by eligible archived files. The software determines when to release disk blocks by using the High Water Mark and Low Water Mark threshold values that you define when you create an archiving file system. You can edit these values on the Edit Mount Options page for the file system.

Stager

Software that restores files to online disk cache. When a user or process requests file data that has been released from disk cache, the stager automatically copies the file data back to the online disk cache.

Recycler

Software that clears archive volumes of expired copies and makes volumes available for reuse.

When you create a file system through the browser interface and you select Archive This File System, the Sun QFS software configures the file system to use the Sun SAM software that is installed locally on the current server.
