Keeping or Reclaiming the Snapshot Space

A Snapshot is a point-in-time image of your volume. This image can be used for

backup or recovery purposes. See “Snapshots” on page 111 for detailed

information. Approximately 20% of the default volume is allocated for snapshot

use.

If you are certain that you will not use snapshots, you can reclaim that space on the

volume by selecting the

Reclaim Snapshot Space radio button in the Initial Setup

Wizard.

Caution If you delete the snapshot space at this time (during the volume

configuration process), you will not be able to restore it later if you decide that you

want to use snapshots. Therefore, it is recommended that you retain the snapshot

space during this initial configuration. You can always delete or reduce it from the

Storage > Snapshots page in the Administration Tool. Or, for servers with no

Snapshots license, you can simply increase your default volume size in the

Storage

> Volumes

page.

Determining Capacity

The factory default configuration reduces potential capacity in order to provide a

high degree of data protection and backup capability. By default, SnapServers with

four (4) to eight (8) disk drives are configured into a RAID 5 created during the

manufacturing process. SnapServers with twelve (12) disk drives are configured

into a RAID 6, and the SnapServer 110 and SnapServer 210 are configured as a 1-

and 2-drive RAID 0, respectively. In a RAID 5 configuration, the capacity of one

drive is used for data protection, reducing the available capacity of the server by

one drive. In a RAID 6 configuration, where two drives are used for data protection,

the available drive capacity of the server is reduced by two.

The GuardianOS runs from a protected partition, which consumes approximately

1 GB of space from each disk depending on the total capacity of the disk drive.

Approximately 20% of the default RAID is available for snapshot space and 80% of

the default RAID assigned to the primary data volume.
