Chapter 2 Snapserver Storage Configuration; Determining Capacity - Overland Storage SnapServer 110 Configuration And Hardware Options Manual

SnapServer Storage
Configuration
Note
The SnapServer 110 is a single disk server that does not support RAID
configurations other than the default RAID 0. The SnapServer 210 is a two-disk
server that supports RAID 0 and RAID 1. Discussions in this chapter of RAID 5,
RAID 6, and RAID 10 configurations and global hot spares only apply to
SnapServers with four (4) or more drives. For more information about RAID
configurations for SnapServer 110 and 210, see the User's Guide for SnapServers 110
and 210 on the User CD.
This section describes the default configurations of SnapServers with four (4) or
more drives and expansion arrays, how to change this configuration, how to add
capacity to the SnapServer by attaching one or more expansion arrays, and how to
prepare the server to store data.
After deploying your SnapServer storage system, you should provision and
configure the servers for optimal use in your network environment. The four
sections in this chapter provide guidelines and procedures for administrators who
are implementing a SnapServer on their network.

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 (SnapServer 110 and SnapServer 210 are configured as a 1-
and 2-drive RAID 0, respectively). SnapServers with twelve (12) drives are
configured into a RAID 6. 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, two drives are used for data protection, so the capacity is
reduced by two drives.
