This section provides information about the servers vital to storage and backup/restore – servers running SQL Server and the backup tape device. For information about how other servers, such as the front-end Web servers and Active Directory servers, were configured, see Windows SharePoint Services Hosting Configuration and Experience, the first paper in this series. See Table 2 in the "Hardware RAID Configuration" section of this paper for information about the hard disk drive configuration on these servers.

The front-end Web servers Veritas backup agent software and Hewlett-Packard Compaq Insight Manager software. The servers running SQL Server ran Hewlett-Packard SAN software and the Veritas backup agent software. The backup server ran Veritas Backup Exec 8.60 for Windows Servers.

• DLT Tape Device: Single Operation Tape Unit (Can perform one backup or restore operations at one time, not concurrent tape operations)
