interface on the SCSI ports. 3590s shipped on or after 29 January 1999, or with feature
#5790 have an Ultra SCSI interface.
Both interfaces allow attachment to the AS/400 system using one of the following controllers:
• #6501 Tape/Disk Device Controller (requires #9410 Interposer for AS/400)
• #6534 Magnetic Media Controller (SPD)
• #2729 Magnetic Media Controller (PCI)
The 3590 has an instantaneous data transfer rate of 9M/sec when attached using fast and
wide SCSI-2. Performance is further enhanced by a 4M buffer. When attached using Ultra
SCSI to a #6501 or #6534, the instantaneous data transfer rate is 17 M/sec. When attached
using Ultra SCSI to a #2729, the instantaneous data transfer rate is 13 M/sec. The actual
throughput achieved is a function of many components and can vary. A maximum of two
3590s may be attached per #6501, but if run concurrently, 3590 performance may be
reduced. The maximum distance between the AS/400 system and the 3590 is 25 meters (82
feet). The #6534 and #2729 Magnetic Media Controller can support a maximum of one 3590
Model B11. For more information on these controllers, see “Magnetic Media Controllers” on
page 383.
The 3590 Model B11 also includes the Advanced Cartridge Function (ACF), which has the
same operational function of an Automatic Cartridge Loader (ACL) but also allows random
access of cartridge tapes. The ACF supports the 10-cartridge magazine that has 10 slots for
the high-performance ½-inch cartridge tapes and a spare slot for a cleaning cartridge. Each
3590 Model B11 is shipped with the ACF, a high performance cartridge tape, a cleaning tape,
and a 10-cartridge magazine. Additional 3590 cartridge magazines can be ordered using
RPQ 8B3184.
The 3590 Model B11 is supported on all AS/400 models except for 9401, D02, E02, and F02.
For PowerPC-based models, the 3590 is supported as an Alternate IPL device. For AS/400
IMPI models, the 3590 requires OS/400 V3R1 or V3R2. It is supported as an Alternate IPL
device on IMPI models only with RPQ 843945, but is not supported for Alternate IPL on 9404
Models D10 and D20.
This RPQ is required because IBM software, PTFs, and MULIC/FULIC tapes will not be
distributed on 3590 media. A second tape drive, in addition to the 3590, must be specified as
a valid Alternate IPL device. The RPQ includes IBM service instructions for attaching the
3590 as an Alternate IPL device, and a license to make a copy of the MULIC/FULIC tape on
3590 tape media.
The 3590 is also supported in the 3494 Tape Library Dataserver as the Model B1A. The 3590
Model B11 can be field upgraded to a Model B1A.
