IBM AS/400e

Magnetic Media Controllers
390 AS/400e System Handbook
Only the 1.03G, 1.96G, 4.19G, 8.58G, and 17.54G disk units are supported under RAID-5
with #6502.
The #6522 High Performance Controller, which was available on 9402 Models 2xx and 4xx, is
functionally equivalent to #6502 and will be converted to #6502 if upgrading to a 7xx model.
New orders should include the #6532 or #6533 instead of the #6502.
#6512 High Performance Controller (4M Cache) SPD
The #6512 disk controller provides unprotected, mirrored, or RAID-5 protection for internal
disk units and includes a 4M write cache for better performance and improved device
utilization.
The #6512 is supported on the 9406 models that have SPD card slots. The #6512 controls
disk units installed in the #5051, #5052, #5058, #8052, and #9051 Storage Expansion Units
and the #5061, #5082, and #5083 Storage Expansion Towers.
On the 9406 Model 720 with the #9364/#5064 System Unit Expansion and the #9331
Expansion Unit for SPD Cards, the #6512 supports up to 15 disk units within the System Unit
Expansion.
The #6512 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
disk units. Disk units not supported in a RAID-5 array can also be attached to the same
#6512 in either unprotected or a mirrored environment.
Only the 1.03G, 1.96G, 4.19G, 8.58G, and 17.54G disk units are supported under RAID-5
with #6512. The #6512 occupies one I/O card slot position. On new orders, the #6532 should
be ordered, instead of the #6512.
#6513 Internal Tape Device Controller SPD
This feature provides a two-byte wide SCSI interface for attachment of one or two internal
tape drives in the 9406 Model 730, 740, and SB1 System Unit. On the 9406 Model 720 with
the #9364/#5064 System Unit Expansion and the #9331 Expansion Unit for SPD Cards, the
#6513 supports up to three internal tape drives located in the System Unit Expansion.
Provides support for up to four internal tape drives in the #5072 and #5073 System Unit
Expansion Towers. The #6513 provides attachment for the following internal tape devices:
• #1349 1.2 GB ¼-inch Cartridge Tape Unit Kit
• #1350 2.5 GB ¼-inch Cartridge Tape Unit Kit
• #1355 13 GB ¼-inch Cartridge Tape Unit Kit
• #1360 7 GB 8mm Cartridge Tape Unit Kit
• #1379 1.2 GB ¼-inch Cartridge Tape Unit Kit
