Externally Attached Automated Libraries366 iSeries HandbookThe 3490E Models F00, F01, F11, and library mode F1A can attach to these controllers:• #6501 Tape/Disk Controller (SPD) requires the #2895 Interposer• #6534 Magnetic Media Controller (SPD)• #2729 PCI External Tape Controller• #2749 PCI Ultra Magnetic Media ControllerThese 3490E Models cannot beshared between iSeries and AS/400e servers.For more information, see “I/O Adapters and Controllers” on page 291.Write support for the 18-track cartridge tape is provided at OS/400 V4R2 or later when the3490 is configured in F-mode. This also allows therandom mode to be selected for the ACLand use of the USEOPTBLK performance parameter on CL commands.The 3490 F1A is the tape component of the 3494 library can be installed in any new3494-L10 or in any new or existing 3494-D10. The 3490 F1A can be upgraded to or from the3490 F11. The Model F1A cannot be intermixed with a Model CxA within a single frame of a3494. There is no 18-track write support or USEOPTBLK support on the Model F1A.IBM Magstar MP 3570 Tape Cassette SubsystemThe 3570 uses a unique, robust, heavy usage tape cassette that isapproximately half the size of the IBM 3490/3590 cartridge tapes. The tapecassette capacity is 7 GB uncompressed and up to 21 GB per cassette withLZ1 data compaction. This tape cassette provides fast access to data byhaving two tape spools with the load point in the middle of the tape. The tapenever leaves the cassette and maintains a self-enclosed tape path. This unique patheliminates tape thread time and ensures higher reliability.The 3570 Tape Subsystem is based on the sametechnology as the IBM 3590 High Performance TapeSubsystem (but media is not interchangeable).PositioningThe advantages of 3570 tape libraries are:• Fast access to data is required such as storagemanagement, network serving, mixed digitallibraries, and image processing• High I/O-intensive operations with multi-useraccess is required• Automated backup and restore or automated archive storage and retrieval are required
