 Superior automation solution
The Magstar 3494 Tape Library, a tape automation system, consists of individual frame units for modular expansion that provides a wide range of configurations. This flexibility enables organizations to start small and grow in an affordable and incremental manner.

The basic building block of the Magstar 3494 is the Lxx Control Unit Frame, which contains a library manager, a cartridge accessor, up to two tape drives, and slots for the storage of tape cartridges. To the Lxx frame, you can add drive frames, storage unit frames, the Magstar Virtual Tape Server, and a high-availability model to create a maximum configuration of 16 frames and two service bays.

The Magstar 3494 supports both Magstar 3590 Model B1A/E1A and 3490E Model F1A tape drives within the same library but in separate frames.
       
 Wide platform connectivity
The Magstar 3494 attaches to multiple systems, including IBM AS/400*, RS/6000*, SP*, and S/390* enterprise servers; selected systems from Sun Microsystems, Hewlett-Packard, and Microsoft** (Windows 2000); and other selected non-IBM platforms.
       
 Exceptional performance
The average mount-access time in a single-frame Magstar 3494 is only seven seconds. The Magstar 3494 can perform up to 265 cartridge exchanges per hour with a single gripper, up to 305 exchanges per hour with the optional dual gripper, and up to 610 exchanges per hour with a dual gripper and dual active accessors.(2) The exchange capability of the accessor can decrease as the number of frames increases because of increased accessor travel.

The time required to inventory tape cartridges in any single library frame (control unit, drive unit, or storage unit) is approximately four minutes.(3)
       
 Magstar Virtual Tape Server
The Magstar Virtual Tape Server has been designed to dramatically reduce tape operation costs and improve overall tape library processing performance.

Based on the IBM Seascape* architecture, the Magstar Virtual Tape Server uses virtual drives composed of RAID 5 disk arrays to cache data and then efficiently fill high-capacity 3590 tape cartridges. This helps reduce the requirements for tape drives, automation devices, media, floor space, and operations personnel. 		Sdp00171.jpg (88469 bytes)
       
 IBM 3466 Network Storage Manager support
When paired with the Magstar 3494, the IBM 3466 Network Storage Manager provides an integrated backup, archive, and disaster recovery system for medium to large distributed, heterogeneous networks. Based on proven IBM Seascape building blocks, the advanced software in this system provides a highly reliable, scalable, and versatile storage solution.
       
 High-capacity cartridges
Magstar 3590 metal particle tape can store up to 20 GB of data (60 GB with 3:1 compression) when using the Magstar 3590 Model E1A tape drive and the Magstar 3590 High Performance Cartridge Tape. This capacity increases to 40 GB (120 GB with 3:1 compression) with the new Magstar 3590 Extended High Performance Cartridge Tape.

The Enhanced Capacity Cartridge System Tape used with the IBM 3490E tape drives can provide a capacity of 800 MB of data (2.4 GB with 3:1 compression).
       
 Simplified I/O operations
A choice of two optional convenience I/O stations provides the capability to add or remove from 10 to 30 cartridges at a time without stopping the operation of the cartridge accessor. The operator can also add cartridges by opening the door of any frame and inserting cartridges in any available slot. In an Lxx Control Unit frame, a high-capacity, user-defined output facility of up to 160 cartridges is available.

An additional high-capacity, user-defined I/O facility of up to 200 cartridges is available for drive or storage frames.
       
 SNMP monitoring support
The 3494 supports SNMP alert messaging, enabling you to monitor 3494 messages from one or more SNMP monitor stations. This initial support provides more than 80 operator-class alert messages covering:
  • 3494 device operations
  • Data cartridge alerts
  • Service requests
  • Magstar Virtual Tape Server alerts
 
 Cost effectiveness
Savings can result from a combination of high performance and reduced requirements with respect to tape drives and cartridges, environmental costs, and personnel. In addition, the same tape library can be shared across multiple platforms such as S/390, AS/400, and open systems, and various non-IBM platforms.

The Magstar 3494 has a small footprint, starting at two and one-half feet wide by five feet deep. This size allows it to fit in most rooms, makes it ideal for vaults, and enables significant savings in floor space.
       
 Magstar 3494 library components
Control unit frame
The control unit frame provides the library manager, console, cartridge accessor, optional convenience I/O stations, optional tape drive, barcode reader, optional ESCON controller, and up to 240 cartridge storage cells. Standard library manager models are configured with eight control unit ports. The 3494 library manager can be expanded to support up to 32 control unit ports. The 32 port enhancement feature allows the flexibility required to add additional 3590 tape drives without having to purchase additional libraries.Configurations include: Model L10--one or two 3490E Model F1A tape drives. Model L12--zero to two SCSI-attached Magstar 3590 tape drives. Model L14--zero to two Magstar 3590 tape drives.

Drive unit frame
The Magstar 3494 drive unit frame provides the capability of adding tape drives and up to 400 cartridge storage cells. Configurations include:
 
  • Model D10--zero to two 3490E Model F1A tape drives.
  • Model D12--zero to six SCSI-attached Magstar 3590 tape drives.
  • Model D14--zero to four Magstar 3590 tape drives and an ESCON and FICON control unit (3590-A60).

A Magstar 3590 A60 control unit installed in a D14 drive unit frame can provide ESCON and FICON support for 3590 tape drives in an adjacent L12, L14, or D12 library frame.

The A60 control unit also incorporates the IBM "Call Home" function, which automatically offers a service alert when a problem occurs integral to the control unit. A service representative can be sent for installation and to transmit information to the IBM support center for evaluation. Alerts can also be sent to multiple pagers to alert key personnel.

Storage unit frame
The Magstar 3494 storage unit frame provides the capability for adding cartridge storage:

Model S10--up to 400 cartridge cells.

Magstar Virtual Tape Server-3494 Model B18 Frame
The Magstar Virtual Tape Server contains a RISC-based microprocessor, storage management functions, and up to 864 GB of disk cache (3:1 compression).

The Extended High-Performance Option enables data compression for host channel attachment and provides larger effective disk capacities, improved performance, and 64 virtual device addressing. Up to 300,000 virtual volumes can be stored in a Magstar 3494 Tape Library with two Model B18 units.

       
  High Availability Model
The High Availability Model (HA1) provides a second cartridge accessor, a second library manager, and two service frames. If the active accessor fails, the second accessor automatically performs all library tape mounts/demounts. The service bays provide a place to repair a failed accessor while library operations continue.

The second library manager remains in standby mode unless a failure occurs. If the active library manager fails, the standby takes control of the entire library.

The High Availability Model, having an optional Dual Active Accessor (DAA) feature that enables both accessors to be active simultaneously, improves the mount/demount performance of the Magstar 3494 Tape Library.
       
  Library manager
The Magstar 3494 library manager controls the following functions:
  • Accessing of cartridges
  • Placement of cartridges in slots
  • Movement of cartridges
  • Automatic drive cleaning
  • Performance optimization
  • Tape handling priorities
  • Error recovery
  • Error logging
  • Media inventory
  • Media pool management
 
 Cartridge accessor
The cartridge accessor is designed for high reliability and performance:
  • The accessor's barcode reader enables rapid inventory management by optically scanning the barcodes on the cartridges.
  • A standard accessor has a single gripper. An optional dual gripper can improve tape cartridge handling performance by as much as 40 percent.
 
 Attachment requirements
Host operating systems send data to Magstar 3590 tape drives through SCSI FICON or ESCON connections and to 3490E tape drives through ESCON, parallel channel, or SCSI connections. Host system software communicates library commands to the Magstar 3494 Library Manager via LAN or RS-232 attachment or through the ESCON and FICON or parallel channel controller.

Now, the Magstar 3494 Tape Library (using 3590 Model EIA Tape Drives) is enhanced to support the growing number of open systems servers that support native fibre channel connection as well as servers connected via the IBM SAN Data Gateway.
 
 S/390
Programming support is provided for MVS/ESA* (using either DFSMS/MVS* or Basic Tape Library Support), TPF, VSE/ESA*, and VM/ESA* operating environments. VM/ESA provides mount and demount tape support for guest operating systems such as VSE/ESA and MVS/ESA.

DFSMS/MVS, System Managed Tape, and the Magstar 3494 together provide full media independence in the library.
 
 AS/400
AS/400 support for the Magstar 3494 is provided by OS/400* and Backup Recovery and Media Services/400 (BRM Services/400).
 
 RS/6000
RS/6000 support is provided for AIX* operating environments through a programming interface for applications and user commands.
 
 Optional software
Tivoli** Storage Manager (formerly ADSM) supports MVS/ESA, VM/ESA, VSE/ESA, AS/400, AIX, Hewlett-Packard, Microsoft Windows, and Sun workstations as server platforms and Magstar 3494 as a storage management device for backing up and managing data.
