2.3.2 SCSI Disks
After the announcement of the 7133 SSA Disk Subsystems, the SCSI Disk subsystems became less common in HACMP clusters. However, the 7135 RAIDiant Array (Model 110 and 210) and other SCSI Subsystems are still in use at many customer sites. We will not describe other SCSI Subsystems such as 9334 External SCSI Disk Storage. See the appropriate documentation if you need information about these SCSI Subsystems.
The 7135 RAIDiant Array is offered with a range of features, with a maximum capacity of 135 GB (RAID 0) or 108 GB

The SCSI adapters that can be used to connect RAID subsystems on a shared SCSI bus in an HACMP cluster are:
