Default Storage Configurations
Snap Servers are preconfigured as a single RAID 5, with a single volume
encompassing the entire RAID, and a single share pointing to the volume. The data
space is preconfigured to allocate 20 percent of the RAID to Snapshots on the single
volume and the remainder of the RAID for the file system.
• The Snap Server 4200, 4400, or 4500 is a 4-disk RAID 5 with no hot spare
• The Snap Server 14000 is an 11-disk RAID 5 and one hot spare
The following table provides details on the Snap Server’s default storage
configuration.

RAID 5
RAID refers to a collection of disk drives that act as
a single storage system.
Hot spare Not
configured
Yes A hot spare is a disk drive that can automatically
replace a damaged drive.
Snapshot pool (20%) (20%) A Snapshot is a consistent, stable, point-in-time
image of a volume (file system) used for backup
purposes. Snapshots are stored on the RAID in a
Snapshot pool, or space reserved on the RAID for
this purpose.
Volumes 1 1 A volume is a logical partition of a RAID’s storage
space that contains a file system. The default
volume (VOL0) organizes the remaining RAID
capacity (after the Snapshot pool) into a single
storage space with a single file system.
Shares 1 1 A share is a virtual folder that maps to the root of a
volume or a directory on the volume. The default
share (SHARE1) maps to the root of the volume.
The share access settings of the default share
grant access to all users and groups over all
protocols.
Snapshot
shares
None None A Snapshot share is a virtual folder that allows
access to all current Snapshots at the same
directory level as the original share on which it is
based.
Quotas Disabled Disabled A quota is a limit on the amount of storage space
on a volume that a user or NIS group can consume.
Directories None None If desired, you can use the Administration Tool
(Storage > Directories) to create a volume’s
directory structure.
