#6532 RAID Disk Unit Controller (4M Cache) Ultra SCSI SPD
The #6532 disk controller provides unprotected, mirrored, or RAID-5 protection for internal
disk units. It includes a 4M write cache for better performance and improved device
utilization.
The #6532 will control Ultra, Fast Wide, and Fast Narrow SCSI disk units located in the #5058
Storage Expansion Unit and #5083 Storage Expansion Tower. The Ultra SCSI disks will give
best performance when attached to a #6532 in these Ultra SCSI Expansion Units or Towers.
These Ultra SCSI disks are 17.54G Disk Unit #6714, 8.58G Disk Unit #6713, 4.19G Disk Unit
#6907, and 1.96G Disk Unit #6906.
The #6532 also supports disks installed in the Storage Expansion Units #5051 and #5052
and in the Storage Expansion Towers #5081 and #5082. None of these are Ultra SCSI Units
and Towers, Therefore, they do not provide full Ultra SCSI performance.
The #5052 and #5082 are supported for migration to the Model 7xx. For the 7xx models, the
#5058 Storage Expansion Unit and #5083 Storage Expansion Towers, which are both Ultra
SCSI, are offered. They provide full Ultra SCSI performance when the disks are attached to a
#6532. One #5058 is supported per #5081 or #5083.
On the 9406 Model 720 with the #9364/#5064 System Unit Expansion and #9331 Expansion
Unit for SPD Cards, the #6532 supports up to 15 disk units located in the system unit
expansion and occupies one card slot.
The #6532 controller supports a maximum of 16 one or two-byte disk units. A minimum of
four disk units of equal capacity are required to implement RAID-5 protection. A maximum of
10 disk units per RAID-5 array are supported. Parity information can be spread across four or
eight disks units. A maximum of four RAID-5 arrays are supported on one #6532. Disk units
not supported in a RAID-5 array can also be attached to the same #6532 in either
unprotected or a mirrored environment.
