3590 Extended High Performance Cartridge
The IBM Magstar 3590 Tape Drive supports the 3590 Extended High Performance Cartridge
Tape (Extended Length Cartridge). This tape has a native capacity of 40 GB on the 3590
Model E11 and E1A tape drives and 20 GB on the 3590 Model B11 and B1A tape drives. All
3590 B and E Models shipped on or after 04 February 2000 support the Extended Length
Cartridge. The 3590 Extended Media Support is also available as an MES upgrade feature for
installed 3590 B and E Model tape drives.
All models of the Magstar 3590 Tape Drive continue to support the 3590 High Performance
Cartridge Tape Cartridge (Standard Length Cartridge).
Performance Statistics for the 3590-E and iSeries 8xx
As you can see in the following table, the 3590 Ultra SCSI data rates, when attached to the
iSeries 8xx, are unleashed and provide up to double the tape operation performance than
was possible on the AS/400e Models 6xx and 7xx. In addition, the system maximum
throughput (concurrent tape device operations) is increased by up to 700% (as measured, not
the limit). Also, there is no longer any limitations on the bus placement concerning the
number of tape devices or the configurations with DASD.
