    reliability. The 3584 library Models L32 and D32 can be equipped with
    IBM LTO Ultrium tape drives and Model D42 can be equipped with DLT 8000
    tape drives. IBM LTO Ultrium tape drives are compact storage devices
    that support the highly intensive read and write operations required by
    today's open system servers. Quantum DLT 8000 drives are high
    performance storage devices supporting the DLTtape format.

    The 3584 UltraScalable Tape Library provides an excellent network data
    reliability. The 3584 Tape Library supports the IBM TotalStorage LTO
    Ultrium 1, 2, and 3 Tape Drives and the IBM TotalStorage 3592 Enterprise
    Tape Drive. IBM LTO Ultrium tape drives are compact storage devices
    designed to support the highly intensive read and write operations
    required by today's open system servers.

    The IBM Ultrium 3 Tape Drive is the third generation of LTO Ultrium
    tape drives in the IBM TotalStorage LTO Ultrium family of products.
    Ultrium 3 Tape Drives and data cartridges can be resident in same 3584
    Tape Library frame with Ultrium 2 or Ultrium 1 Tape Drives and data
    cartridges, and adjacent frames can have 3592 Tape Drives and data
    cartridges. The 3592 Tape Drives are designed to provide high levels of
    performance, functionality, and cartridge capacity supporting the 3592
    tape format, including Write Once Read Many (WORM) media support.

    The 3584 Library Models L32 and D32 can be equipped with IBM
    TotalStorage LTO Ultrium 1, 2, or 3 Tape Drives, the Models L52 and D52
    with IBM TotalStorage LTO Ultrium Fibre Channel Tape Drives, and the
    Models L22 and D22 with the IBM TotalStorage Enterprise Tape Drive 3592.
    The 3584 Models D22, D52, L22, and L52 have a smaller footprint than the
    Models D32 or L32, so they take up less floor space. The Ultrium 3 Tape
    Drives and data cartridges can be resident in the same 3584 Tape Library
    frame with Ultrium 1 or 2 Tape Drives and data cartridges, and adjacent
    frames can have 3592 Tape Drives and data cartridges. The 3584 supports
    mixed media in the same library by supporting the intermix of the Models
    D22, D32, and D52 within a 3584 library. Input/Output (I/O) stations are
    located on the Models L22, L32, or L52 to facilitate tape loading and
    unloading. The 3584 High Availability Model HA1 may be added to the 3584
    Tape Library Base Frame Models L22, L32, or L52. In conjunction with a
    service bay feature on the 3584 Model D22 or D52, the Model HA1 provides
    for the installation and operation of a second library accessor in a 3584
    Tape Library to help improve availability and performance.

    3584 UltraScalable Library Means High Performance

    Industry-leading IBM LTO Ultrium drives can be installed in 3584
    UltraScalable Tape Library Models L32 and D32. DLT 8000 drives can be
    installed in Model D42. The DLT 8000 tape drives are high performance
    drives using 4 read/write channels for high performance. To support high
    performance in a mixed media environment, Models D32 and L32 can be
    intermixed within a 3584 library, and Model L32 supports attachment of
    Models D32 or D42. Input/Output stations are located on the Model L32 to
    facilitate tape loading and unloading.

    The IBM LTO Ultrium tape drives are designed for high performance in a
    streaming mode of operation. Automatic data caching, using an expanded
    cache memory and read/write buffering, enhances performance even further.
    The UltraScalable Tape Library 3584 supports the IBM LTO Ultrium 2 Tape
    Drive in addition to the Ultrium 1 Tape Drive. The IBM LTO Ultrium 2
    Tape Drive is the second generation LTO Ultrium tape drive in the IBM
    TotalStorage LTO Ultrium family of products. The Ultrium 2 Tape Drives
    and cartridges can be resident in the same UltraScalable Tape Library
    3584 frame with original Ultrium 1 Tape Drives and data cartridges.
    Aggregate library data rates of up to 18 TB/hour (with 2:1 compression)
    for a fully configured UltraScalable Tape Library 3584 with 72 tape
    drives, allow extremely high data transfer performance. The average
    drive search time to the first byte of data is 49 seconds for the Ultrium
    2 Tape Drive, and 95 seconds for the Ultrium 1 Tape Drive. Sustained
    data rates during reads and writes on IBM LTO Ultrium 2 Tape Drives have
    more than doubled to 70 MB/sec (using 2:1 compression) and 35 MB/sec in
    native mode. The 3584 library continues to support the original IBM LTO
    Ultrium 1 Tape Drives with data rates of 30 MB/sec (using 2:1
    compression) and 15 MB/sec in native mode. The IBM LTO Ultrium 1 and 2
    Tape Drives are designed for high performance in a streaming mode of
    operation. Automatic data caching, using an expanded cache memory and
    read/write buffering, enhances performance even further.

    Cartridge move time within the 3584 UltraScalable Tape Library is
    typically less than 3.0 seconds in a single-frame library. A
    dual-gripper accessor can retrieve the next cartridge to be mounted,
    unload the current cartridge, and load the next cartridge, providing the
    following benefits:


    • Saves complete move operations
    • Further improves overall library performance
    • Offers increased redundancy and higher reliability

    When one or more Model D42 libraries are attached, an LTO gripper is
    paired with a DLTtape gripper to improve cartridge handling capability
    using mixed media within the library.

    Ultrium 2 Tape Drive

    The Ultrium 2 Tape Drive offers the following significant improvements
    over the Ultrium 1 Tape Drive:


    • Tape drive performance is more than doubled, up to 35 MB/sec native
      data transfer rate (70 MB/sec with 2:1 compression). Aggregate library
      data rates of up to 18 TB/hour (with 2:1 compression) for a fully
      configured 3584 library allow extremely high data transfer performance.
      IBM Ultrium 2 Tape Drives can read and write original LTO Ultrium Data
      Cartridges at original Ultrium 1 capacities and with improved performance
      up to 20 MB/sec native data transfer rate (40 MB/sec with 2:1
      compression).

    • The tape cartridge capacity is doubled up to 200 GB native capacity
      (400 GB with 2:1 compression), with the use of the new Ultrium 200 GB
      Data Cartridge. The 3584 library can contain up to 496 TB (992 TB with
      2:1 compression), using up to 72 IBM Ultrium 2 Tape Drives in up to six
      3584 library frames.

    • Digital Speed Matching - The Ultrium 2 Tape Drive will perform
      dynamic speed matching to adjust the drive's native data rate as closely
      as possible to the net host data rate (after data compressibility has
      been factored out). This provides the dual benefit of reducing the
      number of backhitch repositions and improving throughput performance.

    • Power Management - The Ultrium 2 Tape Drive power management function
      controls the drive electronics to be either completely turned off or to
      be in a low-power mode. These power modes occur only when the circuit
      functions are not needed for drive operation.

    • Channel Calibration - The Ultrium 2 Tape Drive channel calibration
      feature allows for customization of each read/write data channel for
      optimum performance. The customization enables compensation for
      variations in the recording channel transfer function, media
      characteristics, and read/write head characteristics.

    • Separate Writing of Multiple Filemarks - Separate writing of multiple
      filemarks causes any write command of two or more filemarks to cause a
      separate data set to be written containing all filemarks after the first.
      This feature has two advantages. First, it improves performance if a
      subsequent append overwrites somewhere after the first filemark. Second,
      write of multiple filemarks typically indicates a point where an append
      operation might occur after the first of these filemarks. This change
      prevents having to rewrite datasets containing customer data and the
      first filemark in cases if such an append occurs.

    • Ultrium 1 Cartridge Compatibility - The Ultrium 2 Tape Drive can read
      and write on Ultrium 1 cartridges with improved transfer rates.

    • Wide Attachment Options - The IBM Ultrium 2 Tape Drives come with
      SCSI Ultra160 LVD, Ultra SCSI HVD, or switched fabric 2 Gbps Fibre
      Channel attachments for connection to a wide spectrum of open system
      gigabytes to terabytes, this powerful pairing can grow with you, helping
      protect your investment.

      3584 Tape Library means high performance

      The IBM LTO Ultrium Tape Drives and 3592 Tape Drives are designed for
      high performance in a streaming mode of operation. Automatic data
      caching, using an expanded cache memory and read/write buffering,
      enhances performance even further. Aggregate library data rates for a
      fully configured 3584 Tape Library supports extremely high data transfer
      performance.

      Cartridge move time within the 3584 Tape Library is typically less
      than 3.0 seconds in a single-frame library. The dual-gripper accessor
      can retrieve the next cartridge to be mounted, unload the current
      cartridge, and load the next cartridge, providing the following potential
      benefits as compared to a single gripper:


      • Save complete move operations
      • Improve overall library performance
      • Offer increased redundancy and higher reliability

      3584 Tape Library defines high reliability

      Leading-edge technology positions the 3592 and IBM LTO Ultrium Tape
      Drives as industry leaders. Highly accurate recording is supported by an
      exclusive thin-film write module designed by IBM with read-after-write
      data verification. Data read is managed by IBM's industry-leading
      Magneto Resistive (MR) heads, designed for accuracy, high reliability,
      and durability. The 3584 drives and library robotics are
      TapeAlert-compatible, providing tape drive, and library error and
      diagnostic reporting. Drive cleaning is an automatic function that can
      be performed by the library when required by the drive, without requiring
      operator intervention.

      High granularity in library configurations

      Features and capacities are designed to match a wide variety of
      customer requirements. You can attach up to 15 Model D22, D32, or D52
      Expansion Frames to a Model L22, L32, or L52 Base Frame to tailor the
      library to match your system capacity and performance needs. This
      provides a cartridge capacity with Ultrium data cartridges of up to 6,887
      cartridges, or with 3592 data cartridges of up to 6,260 cartridges You
      can intermix cartridges and drive types in different frames and have up
      to 192 tape drives in up to 16 total 3584 library frames. If a Model D42
      Frame is attached, the maximum number of Expansion Frames that can be
      attached to the Model L32 is five.

      Model L32 (Base Frame)

      The 3584 Model L32 Base Frame is designed for IBM LTO Ultrium Tape
      Drives and LTO data cartridges. The Model L32 Base Frame has 87 to 281
      cartridge slots and support for up to 12 tape drives with an incremental
      reduction of storage slots for more than four drives or with the
      additional I/O station installed. Data capacity for the Model L32
      depends on the types of cartridges. Up to 12 logical libraries (one per
      tape drive) can be configured for each frame.

      Each Model L32 library has a standard 10-slot cartridge I/O station
      for importing or exporting LTO tape cartridges from the library without
      requiring a re-inventory. An additional 16-slot cartridge I/O is
      optionally available for 3592 data cartridges or an additional 20-slot
      cartridge I/O is optionally available for LTO data cartridges. Libraries
      containing a mixture of LTO and 3592 drive technologies must have one LTO
      I/O station and one 3592 I/O station. For bulk loading of tape
      cartridges the library door can be opened. Each time the library door is
      closed, a bar code reader mounted on the autochanger scans the cartridge
      labels enabling a re-inventory of the cartridges in the library frame in
      typically less than 60 seconds. A door lock is included to restrict
      physical access to cartridges in the library.

      Designed for availability

      If you are looking to maximize availability with minimum downtime for
      service-related activities, you will appreciate that the library
      preserves tape drive configuration settings, such as Fibre Channel World
      Wide Node Names (WWNN), when a tape drive is replaced. This helps to
      ensure that the replacement drive has the same WWNN as the original drive
      and may help avoid the need to re-IPL or reconfigure host systems. Fibre
      Channel drives require only a quiesce of the individual drive. Redundant
      hot-swap library and drive power supplies can also be replaced without
      any impact to host sytems.

      ALMS is designed to eliminate outages when adding Capacity On Demand
      (COD) storage, adding or removing logical libraries, or when changing
      logical library storage allocation. The use of ALMS may also reduce
      outages when adding expansion frames, adding or removing tape drives, or
      changing logical drive allocation.

      A Dual AC Power feature, supporting either 110 Volt ac or 220 Volt ac,
      provides a power switch to allow connection of two line cords to two
      independent customer branch circuits. This can enhance library
      availability by having an alternative power source in case of planned or
      unplanned power grid outages.

      3584 High Availability Frame Model HA1

      The 3584 High Availability Frame Model HA1 is designed to improve the
      performance and availability of the 3584 Tape Library. The Model HA1, in
      conjunction with service bay features on the 3584 Models D22 and D52,
      provide for the installation of a second library accessor that is
      designed to operate simultaneously with the first accessor and service
      mount requests in the 3584 Tape Library at the same time. It is designed
      to non-disruptively failover to a redundant accessor when any component
      of either accessor fails, which helps maintain availability and
      relibility. Additionally, this design includes the ability to add one or
      more Model D52 or D22 Frames to a 3584 Tape Library that has an attached
      Model HA1 with minimal disruption.

      Dual active accessor support is provided in a mixed media library.
      This includes any combination of 3592 and LTO Ultrium media types.
      Advanced Library Management Systems (ALMS) will be required for support
      of dual accessors and two or more 3584 frames are required in a high
      availability configuration.

      A dual accessor library will have two garage areas called service
      bays. Service Bay A (the 3584 High Availability Frame Model HA1) is to
      left of and adjacent to the L-frame, when facing the front door. Service
      Bay B (a modified 3584 Model D22 or D52) is to the right of the last
      active frame in the library. The service bays will be regular library
      frames but they will not have any drives, power supplies, or node cards.
      Storage slots within the service bays will only be used to test service
      actions.

      The actual performance of the 3584 Tape Library is determined by a
      number of factors, such as: accessor capacity, number of library frames,
      number of tape drives, location of tape drives and tape cartridges, and
      tape cartridge residency.

      Multi-Path support

      The Multi-Path Architecture of the 3584 Tape Library provides the
      capability for sharing of the library robotics. This is accomplished by
      partitioning the library into up to 192 multiple logical libraries (up to
      the number of drives installed), and providing each logical library its
      own separate and distinct drive(s), storage slots, and control path(s).
      I/O slots are shared on a first-come-first-served basis. This type of
      partitioning allows heterogeneous applications to share the library
      robotics independent of each other. Cartridges under library control are
      not shared between logical libraries, nor allowed to be moved between
      logical libraries. An example of heterogeneous sharing is a Microsoft
      Windows 2000 application using the drive and storage slots of one logical
      library, while a UNIX application uses the drive and slots of another
      logical library.

      Logical libraries can also be used for separating different
      generations of Ultrium Tape Drives and cartridges, or 3592 Tape Drives
      and cartridges, for applications which do not support mixing the drives
      in the same logical library.

      Advanced Library Management System

      The Advanced Library Management System (ALMS) is the next generation
      of patented IBM Multi-Path Architecture. ALMS provides a license key to
      enable dynamic management of cartridges, cartridge storage slots, tape
      drives, and logical libraries. Tape drives can be assigned to any
      logical library using a Web user interface. Logical libraries can be
      added, deleted, or easily changed non-disruptively. Storage capacity can
      typically be changed without any impact to host applications. ALMS is
      required when a 3584 High Availability Frame Model HA1 is installed in
      the 3584 Tape Library.

      Control Path Failover

      Two types of path failover capabilities exist: Control Path Failover
      (CPF) and Data Path Failover (DPF). Control refers to the command set
      that controls the library (the SCSI Medium Changer command set on LUN 1
      of the tape drives). Data refers to the command set that carries the
      customer data to and from the tape drives (the SCSI-3 Stream Commands
      (SSC) device on LUN 0 of the tape drives). Path failover means the same
      thing in both: that is, where there is redundancy in the path from the
      application to the intended target (the library accessor or the drive
      mechanism), the device driver transparently fails over to another path in
      response to a break in the active path.

      Both types of failover include host-side failover when configured with
      multiple host bust adapter (HBA) ports into a switch, but CPF includes
      target-side failover through the control paths that are enabled on more
      than one tape drive. DPF includes target-side failover for 3592 Tape
      Drives only by using the dual-ported interface of the drive.

      For enhanced availability you may use CPF. This optional feature is
      designed to provide automatic control path failover to a preconfigured
      redundant control path in the event of a loss of a host adapter or
      control path drive, without aborting the current job in progress.
      Support is currently provided under AIX, Solaris, and Linux when the IBM
      device driver is used. Additional operating systems support will be
      provided in the future for installed CPF users.

      Data Path Failover and Load Balancing

      Data Path Failover (DPF) and Load Balancing exclusively supports
      native Fibre Channel Ultrium Tape Drives and 3592 Tape Drives in the 3584
      Tape Library using the IBM device driver. Support is currently provided
      for AIX, Linux, and Solaris. Additional operating systems support will
      be provided in the future for installed DPF users. DPF is designed to
      provide a failover mechanism in the IBM device driver, which enables you
      to configure multiple redundant paths in a SAN environment. In the event
      of a path or component failure, the failover mechanism is designed to
      automatically provide error recovery to retry the current operation using
      an alternate, preconfigured path without aborting the current job in
      progress. This allows you flexibility in SAN configuration,
      availability, and management.

      When accessing a tape drive device that has been configured with
      alternate pathing across multiple host ports, the IBM device driver
      automatically selects a path through the HBA that has the fewest open
      tape devices, and assigns that path to the application. This autonomic
      self-optimizing capability is called Load Balancing. The dynamic load
      balancing support is designed to optimize resources for devices that have
      physical connections to multiple HBAs in the same machine. The device
      driver is designed to dynamically track the usage on each HBA as
      applications open and close devices, and balance the number of
      applications using each HBA in the machine. This may help optimize HBA
      resources and improve overall performance. Further, DPF provides
      autonomic self-healing capabilities similar to CPF, with transparent
      failover to an alternate data path in the event of a failure in the
      primary host-side path.

      Note: DPF and Load Balancing for Ultrium 3 Tape Drives, or Ultrium 2 Tape
      Drives attached to operating systems other than AIX, requires an optional
      feature. Load Balancing is not currently supported for Solaris.

      Fibre Channel connectivity

      Tape drives in the 3584 Tape Library Models D22, D52, L22, and L52 are
      designed to connect to host systems using Fibre Channel interfaces. An
      LTO Ultrium Tape Drive with a Fibre Channel interface or 3592 Tape Drive
      can be selected for attachment to host systems and servers utilizing
      Fibre Channel adapters. Fibre Channel connection distances up to 300
      meters (at 2-Gbps) are possible. By utilizing selected Fibre Channel

    Proven IBM LTO Ultrium 1 features enhanced in IBM LTO Ultrium 2 Tape

    The Ultrium 3 Tape Drive incorporates third-generation IBM LTO Ultrium
    technology. It offers the following significant improvements over the
    Ultrium 2 Tape Drive:


    • Maximum tape drive throughput data rate performance is more than
      doubled, up to 80 MB/sec native data transfer rate. Data tracks are now
      written 16 at a time. IBM Ultrium 3 Tape Drives can read and write, at
      eight data tracks at a time, LTO Ultrium 2 Data Cartridges at Ultrium 2
      rates, and read LTO Ultrium 1 Data Cartridges at Ultrium 1 rates.

      Note: Although the 3588 Tape Drive provides the capability for excellent
      tape performance, other components of the system may limit the actual
      performance achieved. Also, although the compression technology used in
      the tape drive can typically double the amount of data that can be stored
      on the media, the actual degree of compression achieved is highly
      sensitive to the characteristics of the data being compressed.

    • The tape cartridge capacity is doubled over the Ultrium 2 Data
      Cartridge up to 400 GB native physical capacity (800 GB with 2:1
      compression), with the use of the new IBM TotalStorage LTO Ultrium 400 GB
      Data Cartridge. This is achieved by increasing the linear density, the
      number of tape tracks, and the media length. The tape itself is an
      advanced metal particle tape developed to help provide durability and
      capacity.

    • Ultrium 2 cartridge compatibility - The Ultrium 3 Tape Drive can read
      and write on LTO Ultrium 2 Data Cartridges and can read LTO Ultrium 1
      Data Cartridges.

    • 2-Gbps Fibre Channel attachment - The 3588 Model F3A comes with a
      2-Gbps Fibre Channel interface for connection to a wide spectrum of open
      system servers. They are supported on AIX, OS/400, i5/OS, Sun Solaris,
      HP-UX, Microsoft Windows 2000, Windows 2003, Linux, and other open
      systems.

    • New dual stage 16 channel head actuator - designed to provide
      precision head alignment to help support higher track density and
      improved data integrity.

    • New independent tape loader and threader motors and positive pin
      retention - designed to help improve the reliability of loading and
      unloading a cartridge, and to retain the pin even if tension is dropped.
      With an independent loader motor coupled with the positive pin retention,
      the tape threads with a higher level of reliability.

    • Larger internal data buffer - There is a 128 MB internal data buffer
      in the Ultrium 3 Tape Drive as compared to a 64 MB internal data buffer
      in the Ultrium 2 Tape Drive or a 32 MB internal data buffer in the
      Ultrium 1 Tape Drive.

    • Highly integrated electronics using IBM-engineered copper technology
      - designed to reduce the total number of components in the drive, lower
      chip temperatures, and reduce power requirements, helping to provide for
      a more reliable drive. The generation 3 drive electronics are also
      designed to provide "on-the-fly" error correction capability for soft
      errors in the memory arrays in data and control paths.

    • Graceful dynamic braking - In the event of power failure, reel motors
      are designed to maintain tension and gradually decelerate instead of
      stopping abruptly, helping reduce tape breakage, stretching, or loose
      tape wraps during a sudden power-down.

  • Servo and track layout technology - There are 512 data tracks in
    Ultrium 2 verses 384 data tracks in Ultrium 1.

  • Servo and track layout technology - There are 704 data tracks in
    Ultrium 3 verses 512 data tracks in Ultrium 2 and 384 data tracks in
    Ultrium 1. High bandwidth servo system features a low-mass servo to help
    more effectively track servo bands and improve data throughput with
    damaged media in less-than-optimal shock and vibe environments.

    Guiding Mechanism guides the tape along the tape path in the IBM Ultrium
    3580. This method uses the surface of the tape, rather than the edges,
    to control tape motion. This results in less tape damage (especially to
    the edges of the tape) and less tape debris, which comes from the damaged
    edges and can accumulate in the head area.

  • Magneto Resistive (MR) Head Design - Use of flat lap head technology
    in MR heads for Ultrium 2 minimize contact and wear on the tape as it
    moves over the read/write heads.

  • LTO Data Compression (LTO-DC) - The Ultrium 2 uses LTO-DC which is an
    implementation of a Lempel-Ziv class 1 (LZ-1) data compression algorithm.
    LTO-DC is an extension of Adaptive Lossless Data Compression (ALDC) and
    an improvement over previous lossless compression algorithms. Users of
    LTO-DC can expect to achieve better data compression as users of ALDC.

  • Magneto Resistive (MR) head design - Use of flat lap head technology
    in MR heads helps minimize contact, debris accumulation, and wear on the
    tape as it moves over the read/write heads.

  • Digital speed matching - The Ultrium 3 Tape Drive is designed to
    perform dynamic speed matching (at one of five speeds, 40, 50, 60, 70, 80
    MB/sec) to adjust the drive's native data rate as closely as possible to
    the net host data rate (after data compressibility has been factored
    out). This helps reduce the number of backhitch repositions and improve
    throughput performance. Speed matching on Ultrium 3 ranges from 40 to 80
    MB/sec versus 17.5 to 35 MB/sec on Ultrium 2.

  • Robust drive components optimized for automation environments - Drive
    designed using some of the most robust components available, such as: 1)
    all metal clutch, 2) steel ball bearings in loader, 3) robust leader
    block design, 4) single circuit card, to help enhance reliability and
    prolong the life of the drive.

  • Power management - The power management function is designed to
    control the drive electronics to be either completely turned off or to be
    in a low-power mode when the circuit functions are not needed for drive
    operation.

  • Channel calibration: The channel calibration feature allows for
    customization of each read/write data channel to support optimum
    performance. The customization enables compensation for variations in
    the recording channel transfer function, media characteristics, and
    read/write head characteristics.

  • Adaptive read equalization - designed to automatically compensate for
    dynamic changes in readback signal response.

  • Dynamic amplitude asymmetry compensation - designed to dynamically
    optimize readback signals for linear readback response from magneto
    resistive read head transducers.

  • Separate writing of multiple filemarks - Separate writing of multiple
    filemarks is designed to cause any write command of two or more filemarks
    to cause a separate data set to be written containing all filemarks after
    the first. This feature has two advantages. First, it helps improve
    performance if a subsequent append overwrites somewhere after the first
    filemark. Second, the write of multiple filemarks typically indicates a
    point where an append operation might occur after the first of these
    filemarks. This change helps prevent having to rewrite datasets
    containing customer data and the first filemark in cases if such an
    append occurs.

  • LTO Data Compression (LTO-DC) - The IBM Ultrium Tape Drives use
    LTO-DC which is an implementation of a Lempel-Ziv class 1 (LZ-1) data
    compression algorithm. LTO-DC is an extension of Adaptive Lossless Data
    Compression (ALDC) and an improvement over previous IBM lossless
    compression algorithms. IBM's patented "Scheme-Swapping" compression is
    designed to look ahead at incoming data, and determine the most efficient
    storage method (either ALDC or pass-thru mode) to help provide optimal
    data compression and increased data throughput.

  • Statistical Analysis and Reporting System (SARS) - The Ultrium 2 Tape
    Drive uses SARS to assist in isolating failures between media and
    hardware. The SARS use the cartridge performance history saved in the CM
    module and the drive performance history kept in the drive flash EEPROM
    to determine the more likely cause of failure. SARS can cause the drive
    to request a cleaner tape, to mark the media as degraded, and to indicate

    3584 UltraScalable Library Features Improved Connectivity

    The 3584 UltraScalable Tape Library is designed to connect to host
    systems using any combination of Fibre Channel and SCSI interfaces.
    Customers who wish to use Fibre Channel should choose drive features
    #1476 or #1456. Customers with systems using a Ultra160 Low Voltage
    Differential (LVD) SCSI interface should choose drive feature #1474.
    Customers with systems using a Ultra2/Wide Low Voltage Differential (LVD)
    SCSI interface should choose drive feature #1454. Customers with systems
    using an Ultra/Wide High Voltage Differential (HVD) interface should
    choose drive features #1475 or #1455.

    The 3584 library, with drive features #1476 or #1456, supports
    connectivity to host systems and servers utilizing Fibre Channel
    adapters. Connection distances up to 500 meters are possible, and by
    utilizing the IBM 2103 SAN Fibre Channel Storage Hub, or the IBM 2109 SAN
    Fibre Channel Switch, or the IBM 3534 SAN Fibre Channel Managed Hub,
    distances exceeding 500 meters are possible.

    3584 UltraScalable Library Defines High Reliability

    Leading-edge technology positions the IBM LTO Ultrium 1 and 2 Tape
    Drives as industry leaders. Highly accurate recording is provided by an
    exclusive thin-film write module designed by IBM with read-after-write
    data verification. Data read is managed by IBM's industry-leading MR
    heads, designed for accuracy, high reliability, and durability. The 3584
    drives and library robotics are TapeAlert-compatible, providing tape
    drive, and library error and diagnostic reporting. Drive cleaning is an
    automatic function performed by the library when required by the drive,
    without requiring operator intervention.

    High Granularity in Library Configurations

    Features and capacities are designed to match the wide variety of
    customer requirements. The Ultrium 1 and 2 Tape Drives can be placed in
    either the UltraScalable Tape Library Base Frame 3584 Model L32 or the
    UltraScalable Tape Library Expansion Frame 3584 Model D32. You can
    tailor the library to match your system capacity and performance needs
    from 28 TB to 1,376 TB (56 TB to 2,752 TB with 2:1 compression), using up
    to 192 IBM LTO Ultrium 2 tape drives in up to 16 total 3584 library
    frames.

    Model L32 (Base Frame)

    The Model L32 Base Frame has 141 to 281 cartridge slots and support
    for up to 12 tape drives with an incremental reduction of storage slots
    for more than four drives. Data capacity for the Model L32 depends on
    the types of cartridges, up to 112 TB (at 2:1 compression) using LTO-DC.
    Up to 12 logical libraries and/or up to 12 SCSI control paths can be
    configured for each frame.

    Each Model L32 library has a standard 10-slot cartridge input/output
    station for importing or exporting cartridges from the library without
    requiring a re-inventory. For bulk loading of tape cartridges the
    library door can be opened. Each time the library door is closed, a bar
    code reader mounted on the autochanger scans the cartridge labels
    enabling a re-inventory of the cartridges in the library frame in less
    than 60 seconds. A door lock is included to restrict physical access to
    cartridges in the library.

    Expansion Frames

    The Model L32 is designed to allow expansion of the library up to
    15 Model D32 Frames. This provides you investment protection for
    your installed library, and the flexibility to expand and grow the
    3584 library to meet your increasing storage and application needs.
    If a Model D42 Frame is attached, the maximum number of Expansion
    Frames that can be attached to the Model L32 is five.
    Model D32 and D42 frames can be intermixed between LTO and
    DLTtape providing flexible configurations to meet your requirements.

    Designed for Availability

    Customers looking for maximum availability with minimum downtime for
    service-related activities will appreciate the capability for replacing
    drives and power supplies without having to re-IPL the host systems.
    Fibre Channel drives require only a quiesce of the individual drive,
    SCSI-attached drives and control ports require a quiesce of the affected
    bus.

    A Dual AC Power feature, supporting either 110 Volt ac or 220 Volt ac,
    provides two independent line cords that may be connected to two
    independent customer branch circuits. This can enhance library
    availability by having an alternative power source in case of planned or
    unplanned power grid outages.

    Multi-Path Support

    The heterogeneous sharing provided by the multi-path feature of the
    UltraScalable Tape Library 3584 provides a sharing of the library
    robotics. This is accomplished by partitioning the library into up to 72
    multiple logical libraries (up to the number of drives installed), and
    providing each logical library its own separate and distinct drive(s),
    storage slots, and control path(s). Input/output (I/O) slots are shared
    on a first-come-first-served basis. This type of partitioning allows
    heterogeneous applications to share the library robotics independent of
    each other. Cartridges under library control are not shared between
    logical libraries, nor allowed to be moved between logical libraries. An
    example of heterogeneous sharing is a Microsoft Windows 2000 application
    using the drive and storage slots of one logical library while a UNIX
    application uses the drive and slots of another logical library.

    Logical libraries can also be used for separating Ultrium 1 Tape
    Drives and cartridges from Ultrium 2 Tape Drives and cartridges, for
    applications which do not support mixing the drives in the same logical
    library.

    Control Path Failover for AIX

    For enhanced availability you may use Control Path Failover for AIX.
    This optional feature provides automatic control path failover to a
    pre-configured redundant control path in the event of a loss of a host
    adapter or control path drive, without aborting the current job in
    progress. Support is provided under AIX for both SCSI and Fibre Channel
    attachments when the IBM Atape device driver is used.

    Data Path Failover and Load Balancing

    Data Path Failover and Load Balancing exclusively supports native
    Fibre Channel Ultrium 2 Tape Drives in the UltraScalable Tape Library
    3584 using the IBM Ultrium Device Driver for AIX. When accessing an
    Ultrium 2 device that has been configured with alternate pathing across
    multiple host ports, the IBM Ultrium Device Driver automatically selects
    a path through the host bus adapter (HBA) that has the fewest open tape
    devices. This autonomic self-optimizing capability is called Load
    Balancing. Further, Data Path Failover provides autonomic self-healing
    capabilities similar to Control Path Failover, with transparent failover
    to an alternate data path in the event of a failure in the primary
    host-side path.

    110 Volt AC Attachment

    The UltraScalable Tape Library 3584 now supports a power cord for 110
    Volt ac attachment. This is an alternative to the 220 Volt to 240 Volt
    ac power cord attachment previously provided and can expand operation of
    the 3584 in open system environments that require 110 Volt ac.

    Manageability Improvements

    The following improvements in administration and support of tape
    drives and media have been included:

    With support for LTO Ultrium-format tape data cartridges, the 3588
    Tape Drive with the 3584 Tape Library can be a cost-effective solution
    for backup, save-and-restore, and archiving functions.

    Ultrium 2 Tape Drive

    The Ultrium 2 Tape Drive offers the following significant improvements
    over the Ultrium 1 Tape Drive:


    85,413c492,524

  • The ability to monitor drive TapeAlert events in order to trigger
    Call Home and SNMP traps

  • Use of the IBM TotalStorage UltraScalable Tape Library Specialist to
    remotely power cycle any canister tape drive

    cartridges are imported into the library

    High-Performance LTO Ultrium Tape Cartridge

    The tape cartridge capacity of the IBM TotalStorage Ultrium 200 GB
    Data Cartridge has doubled over the original IBM TotalStorage Ultrium
    Data Cartridge to 200 GB native capacity (400 GB with 2:1 compression).
    IBM LTO Ultrium 2 Tape Drives can read and write original Ultrium 1 data
    cartridges, and Ultrium 2 Tape Drives and cartridges can be resident in
    the same 3584 UltraScalable frame with the original Ultrium 1 Tape Drives
    and data cartridges.

    Both cartridges have been designed to provide several enhancements
    over previous tape technologies. They are designed to work with tape
    drives that have increased tape speeds and high-density data recording.
    The case is specially designed for use in automated libraries and is
    designed for repeated, unattended, trouble-free handling. The tape
    itself is an advanced metal particle tape developed for durability and
    capacity.




  • Maximum tape drive performance is more than doubled, up to 35 MB/sec
    native data transfer rate (70 MB/sec with 2:1 compression) when using the
    Ultrium 200 GB Data Cartridge. IBM Ultrium 2 Tape Drives can read and
    write original LTO Ultrium Data Cartridges at original Ultrium 1
    capacities and with improved performance up to 20 MB/sec native data
    transfer rate (40 MB/sec with 2:1 compression).

  • The tape cartridge capacity is doubled up to 200 GB native capacity
    (400 GB with 2:1 compression), with the use of the Ultrium 200 GB Data
    Cartridge.

    High-performance LTO Ultrium Tape Cartridge

    The tape cartridge capacity of the IBM TotalStorage Ultrium 400 GB
    Data Cartridge has doubled over the IBM TotalStorage Ultrium 2 Data
    Cartridge to 400 GB native capacity (800 GB with 2:1 compression). The
    Ultrium 2 Data Cartridge has a 200 GB native capacity (400 GB with 2:1
    compression) and the Ultrium 1 Data Cartridge has a 100 GB native
    capacity (200 GB with 2:1 compression). IBM LTO Ultrium 3 Tape Drives
    can read and write Ultrium 2 data cartridges, and read Ultrium 1 data
    cartridges. IBM LTO Ultrium 2 Tape Drives can read and write original
    Ultrium 1 data cartridges. Ultrium 3 Tape Drives and cartridges can be
    resident in the same 3584 Tape Library frame with Ultrium 1 or 2 Tape
    Drives and data cartridges.

    Software Requirements


    The UltraScalable Tape Library 3584 is supported on the following
    operating systems at the minimum levels indicated:

    The IBM 3584 UltraScalable Tape Library attaches to a server using a
    Fibre Channel adapter, an Ultra2 SCSI LVD adapter, or an Ultra SCSI HVD
    adapter. With IBM LTO Ultrium drives, the library can be configured to
    have up to 72 control paths and up to 72 logical libraries. The library
    contains the electronics and logic for autochanger operations. Each IBM
    LTO Ultrium tape drive contains the electronics and logic for reading and
    writing data, control of the tape drive, management of the data buffer,
    and error recovery procedures. The IBM 3584 UltraScalable Tape Library
    has its own power and cooling components.

    For mission-critical data protection needs, optimized for enterprise
    multimode and host attachment, high-cycle and start/stop intensive tape
    applications, consider the proven IBM TotalStorage 3592 Tape Drive with
    the IBM TotalStorage 3584 Tape Library or the IBM TotalStorage 3494 Tape
    Library.

  • LTO Ultrium data cartridges have been designed to provide several
    enhancements over previous tape technologies. They are designed to work
    with tape drives that have increased tape speeds and high-density data
    recording. The case is specially designed for use in automated libraries
    and is designed for repeated, unattended, trouble-free handling. The
    tape itself is an advanced metal particle tape developed for durability
    and capacity. The 3584 Tape Library supports the use of Ultrium 1,
    Ultrium 2, Ultrium 3, and 3592 data cartridges within the same library.
