Storage Configuration and
Expansion
Note
Much of the configuration discussion presented here is not applicable to Snap
Servers with fewer than four (4) drives. For Snap Server 110 and 210, see the User’s
Guide for Snap Server 110 and 210 for storage configuration guidelines.
Snap Servers with four or more drives are preconfigured as a single
RAID 5, and Snap Server 110 and 210 are preconfigured with a single
RAID 0. Each server’s disk space is preconfigured with a single volume
encompassing 80 percent of available capacity and a single share pointing
to the volume. The default storage configuration reserves 20 percent of the
data space for snapshots (including servers that require a license to activate
snapshots). If the default configuration is appropriate for your needs, you
need only create the directory structure, set share access permissions, and
(optionally) schedule snapshots.
You may have requirements that demand a different configuration. For
example, if the information on a Snap Server is mission-critical but
infrequently accessed, creating a RAID 1 may be a more suitable
configuration. In another example, some administrators prefer to keep
certain sensitive data, such as financial records, in a separate file system for
added security.
