Section 11: Hard Disk Caching

Section 11 Hard Disk Caching

Note: ❏ The Basic versions of the StorPoint CD do not support hard disk caching.

This section describes how to use hard disk caching with your StorPoint CD.

Hard disk caching means that the inserted discs can be copied to a hard disk attached to the SCSI bus or the IDE bus.

The caching mechanism of the StorPoint CD involves both directory caching and complete mirroring (copying). It allows users to access the networked discs at hard disk speed.

You manage the hard disk caching facility via the StorPoint CD Web interface.

Disc Changers Because of the relatively long time needed to change discs in a changer, the data transfer rate may become unacceptably low when two users simultaneously attempt to read different discs. Hard disk caching will thus significantly increase the access speed if you are using changers.

Archiving The hard disk caching facility allows you to archive the cached discs, i.e. keep the cached discs stored on the hard disk even if the original discs are ejected from the drives. You can archive up to 255 volumes.

Capacity The number of discs that can be cached depends on the size of the hard disks as well as the size of the individual discs. About 90% of the disk space can be used for caching. For example, a 4.3 GB hard disk will allow six 650-MB discs to be cached. However, if each disc contains only 100 MB, about 38 discs can be cached on the hard disk.

A 650 MB disc is cached on the hard disk in less than six minutes.

Note: ❏ Avoid turning off the power supply during hard disk caching. However, should this happen, the StorPoint CD will restart caching the disc/discs

automatically when the power supply has been restored.
