IOP can be controlled by the same SCSI HBA. In the current HP supported configurations, the built-in SCSI channels in an IOP are used for disk card. Note: "Autoloader" tape devices for local backup are not supported at this time. Support of these devices will be available in the future.

Backup/Recovery Guide for HP
Assured Availability Systems
While HP Assured Availability Systems provide very high level of server availability, HP
recommends that backups be done at first install, at upgrade times, and periodically to
preserve data in the event of disasters. This guide provides important information to help
system administrators configure and setup the system for backup.

Backup topologies and tradeoffs
There are many backup topologies one might consider for backing up HP AA systems.
To help system administrators configure and setup backups HP recommends three
topologies.

Figure 1: Pure-local backup configuration
The first topology is a pure-local backup configuration (see figure 1). This configuration uses
a HP SureStore TapeRack with two DLT80r and two DLT40r tape drives. The two DLT80r
tape drives are configured using the Marathon Configuration Utility to be "owned" by the
CEs – each DLT80r act as independent tape drives in the CE. Backup software, such as
Veritas Backup Exec 7.3 or Computer Associates ArcServe IT 6.61, is installed on the CE
