Externally Attached Automated Libraries
366 iSeries Handbook
The 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 Controller
These 3490E Models cannot be
shared
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 the
3490 is configured in F-mode. This also allows the
random mode
to be selected for the ACL
and 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 new
3494-L10 or in any new or existing 3494-D10. The 3490 F1A can be upgraded to or from the
3490 F11. The Model F1A cannot be intermixed with a Model CxA within a single frame of a
3494. There is no 18-track write support or USEOPTBLK support on the Model F1A.
IBM Magstar MP 3570 Tape Cassette Subsystem
The 3570 uses a unique, robust, heavy usage tape cassette that is
approximately half the size of the IBM 3490/3590 cartridge tapes. The tape
cassette capacity is 7 GB uncompressed and up to 21 GB per cassette with
LZ1 data compaction. This tape cassette provides fast access to data by
having two tape spools with the load point in the middle of the tape. The tape
never leaves the cassette and maintains a self-enclosed tape path. This unique path
eliminates tape thread time and ensures higher reliability.
The 3570 Tape Subsystem is based on the same
technology as the IBM 3590 High Performance Tape
Subsystem (but media is not interchangeable).
Positioning
The advantages of 3570 tape libraries are:
• Fast access to data is required such as storage
management, network serving, mixed digital
libraries, and image processing
• High I/O-intensive operations with multi-user
access is required
• Automated backup and restore or automated archive storage and retrieval are required
