• The SSA head device drivers, which deal with devices that are attached to
the SSA adapter. The SSA disk device driver is an example of an SSA
head device driver.
For subsystems that use PCI SSA Multi-Initiator/RAID EL Adapters or Micro
Channel Enhanced SSA Multi-Initiator/RAID EL Adapters, the Target-Mode
SSA (TMSSA) device driver is also available. This device driver provides
support for communications from using system to using system.
4.8.3 Storage Adapter Placement Guidelines for Model 150 and 26 0Table 33 provides information about the placement of the PCI storage
adapters in the Models 150 and 260.

4.9 External SCSI and SSA Storage DevicesThere many external SCSI and SSA storage devices available which can be
attached to the Model 150 and 260.
See also 3.1.3.14, “Supported Devices” on page 63 for details about the
Model 150 and 3.2.4.15, “Supported Devices” on page 89 for details about
