Storage Guides; Factors In Choosing A Raid Type - Overland Storage SnapServer Administrator's Manual

SnapServer 7.0 Administrator's Guide

Storage Guides

Five different storage guides (wizards) are available for creating a RAID set, volume, and
share.
NOTE: If you do not have enough disk drives for the more advanced RAID set configurations,
The basic steps for storage configuration are:
1. Create a RAID set.
2. Create a volume on the new RAID set.
3. Create a share to access files on the new volume.

Factors in Choosing a RAID Type

The type of RAID configuration you choose depends on a number of factors:
• The importance of the data
• Performance requirements
• Drive utilization
• The number of available drives
For example, in configuring the disk drives of a four-drive SnapServer, the decision
whether to include a spare in the RAID depends on the value you place on capacity vs. high
availability. If capacity is paramount, you would use all drives for storage; if high
availability were more important, you would configure one of the drives as a spare.
The following table summarizes the advantages and disadvantages of each type of RAID.
