Storage Configuration and

Expansion

Note Much of the configuration discussion presented here is not applicable to

SnapServers with fewer than four (4) drives. For SnapServer 110 and 210, see the

User’s Guide for SnapServer 110 and 210 for storage configuration guidelines.

SnapServers with four to eight drives are preconfigured as a single RAID 5,

SnapServers with twelve drives are preconfigured with a single RAID 6,

and SnapServer 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 SnapServer 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.
