Externally Attached Automated Libraries380 iSeries Handbookinstantaneous data transfer rate is 13 MB/sec. The actual throughput achieved is a function ofmany components and can vary.A maximum of two 3590s may be attached per #6501, but if run concurrently, the 3590’sperformance may be reduced. The #6534, #2729, and #2749 PCI Ultra Magnetic MediaController can support a maximum of one 3590 Model B11. For more information on thesecontrollers, see “I/O Adapters and Controllers” on page 291.The 3590 Model B11 includes the Advanced Cartridge Function (ACF), which has the sameoperational function of an Automatic Cartridge Loader (ACL), but also allows random accessof cartridge tapes. The ACF supports the 10-cartridge magazine that has ten slots for thehigh-performance ½-inch cartridge tapes and a spare slot for a cleaning cartridge. Each 3590Model B11 is shipped with the ACF, a high performance cartridge tape, a cleaning tape, and a10-cartridge magazine. Additional 3590 cartridge magazines can be ordered using RPQ8B3184.The 3590 Model B11 is supported on all iSeries and AS/400e models as an Alternate IPLdevice.The 3590 is also supported in the 3494 Tape Library Dataserver as the Model B1A. The 3590Model B11 can be field upgraded to a Model B1A.IBM 3590 High Performance Tape Subsystem Models E1A and E11The IBM Magstar 3590 High Performance Subsystem Model E11 tape drive is arack-mountable model using high performance ½-inch tape cartridges. The 3590 E Modelscan read or write twice as much data as the B1X Models on the 3590 High PerformanceCartridge Tape. With the E1X Models, the cartridge can contain up to 20 GB or with theextended length cartridge up to 40 GB of native/uncompressed data per cartridge (60 GB or120 GB with a 3:1 compression ratio respectively).Positioning• High performance solution for backup/retrieval and archive• Proven performance, reliability, and capacity for data storage needs• Large investment in Magstar 3590 tapes• Can install up to four drives in a space saving rack configuration• Leading industry standard tape solutionFully written tapes are positioned back at the load point, virtually eliminating the rewindoperation as with 3490E tape drives. The “locate” function has been enhanced to position thedrive on the proper track and location without having to sequentially search the entirerecorded tape.
