Chapter 10. Attaching an external tape device to the SAS
RAID Module
The SAS RAID Module has four 3.0 GB external SAS Ports that you can use to
attach an external SAS storage tape device. This chapter describes the installation
process for the following supported tape devices:

Tape device considerations
To create a successful backup solution using SAS storage tape devices, consider the
following:
v
The backup software that you use must support the operating environment,
including connectivity topologies, tape devices, and operating systems.
v The SAS RAID Module does not support configurations where multiple servers
are able to access the same tape device simultaneously. However, this type of
configuration may be supported by application software offered from third
parties.
v
For optimal backup performance, do not mix tape devices with disk storage
devices on the same HBA port.
v
Use zoning to isolate different types of traffic when you use an SAS connectivity
module for both disk and tape operations for different servers. For information
on modifying the SAS zoning, see the IBM Storage Configuration Manager
online help.
v LAN-free drive sharing is not supported for the SAS-based tape libraries covered
in this section. Instead, use dedicated backup servers or LAN-based backup
operations.
v
The predefined zones that ship with the SAS switch have external ports enabled.
Ensure that only one application is accessing the tape device at a time.
