Chapter 4 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.
