• 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.
