Section 11: Hard Disk Caching

Caching Options Hard disk caching with the StorPoint CD has two main purposes:

•Increasing performance

•Archiving discs on the hard disk

Performance Caching For performance caching, you specify the cache mode on the Server Settings Change... Caching page. These options are available:

•None - The disc will not be cached.

•Partial - Information about the directory structure and files are cached on to the hard disk, but no actual data. This speeds up the directory browsing, especially with the use of disc changers. Optionally select how much space to allocate to file caching. The file cache is a separated part on a hard disk where disc files may be cached. The more hard disk space allocated to file caching, the larger files can be stored in the file cache.

•Mirror - A copy of the disc is created on the hard disk, and thus increasing performance, especially with multiple users or frequent access of multiple files. This method takes more time to carry out when a new disc is inserted. The mirroring will be performed in the background. Until a disc has been completely cached on the hard disk, the disc will be accessible from the disc drive. If there is not enough room on the hard disk to mirror all required discs, it is advisable to only mirror the most frequently used discs and enable the file cache. The most frequently used non-mirrored disc files will then be placed in the file cache. The file caching option is only available for Partial caching.

For more information, see “Using Hard Disk Caching for Increased Performance ” on page 105.

Archiving Discs The archiving option is only available from the Discs & Drives page:

•Archive - This option does the same as Mirror and in addition saves the created image on the hard disk. The archived disc is accessible to the users even if the original disc has been ejected from the drive. Archiving can be performed manually or automatically for one or more drives.

For more information, see “Using Hard Disk Caching for Archiving Discs ” on page 106.
