Summary of Changes
|
|
|
|
This book contains the following changes to the previous edition.
v Addition of VTS Import/Export functions
v Addition of SCSI attachment capability to VTS subsystems
v Attachment to Microsoft Windows NT processors
Changes to correct errors or omissions in the previous edition are also included.
The 3494 Tape Library automates the retrieval, storage, and control of Cartridge
System Tape, Enhanced Capacity Cartridge System Tape, and High Performance
Cartridge Tape. In conjunction with supporting software and 3490E Models C1A,
C2A and F1A, 3590 Model B1A, 3590 Model A00 or A50, 3494 Model B16 and B18
Virtual Tape Servers, and Model HA1 High Availability Unit, the 3494 allows
cartridges to be mounted and demounted automatically on tape drives.
Figure 1 on page 3 shows three possible configurations of the 3494. The 3494 is
available in multiple configurations using one control unit frame and up to fifteen
optional frames. The available frame types are:
v The tape library control unit frame, 1 or 3, includes the operator panel, a
tape subsystem (3490E Model CxA or F1A with drives, 3590 Model B1A tape
drives, or 3590 Model A00 or A50 Control Unit with drives), a library manager,
cartridge storage cells, a cartridge accessor, and if ordered, the Convenience
Input⁄Output Station. One control unit frame is required in every library
configuration.
v The optional drive unit frame 4 contains additional cartridge storage and may
contain a 3490E Model CxA or F1A tape subsystem, 3590 Model B1A tape
drives, or a 3590 Model A00 or A50 Control Unit with drives.
v The optional Model B16 Virtual Tape Server (VTS) frame 5 contains additional
cartridge storage and the controller and associated disk storage for the VTS. A
drive unit frame4 that holds the 3590 Model B1A tape drives, managed by the
Model B16 VTS, must be located to the left of the Model B16 Virtual Tape Server
frame.
v The optional stand-alone 3494 Model B18 Virtual Tape Server frame 8 contains
the controller and associated disk storage for the VTS. A drive unit frame 4 that
holds the 3590 Model B1A tape drives, managed by the Model B18 VTS, may be
located at any position in the library (except frame 1) but must be within a
distance of 14 m (46 ft.) from the Model B18.
v The optional frame 6 contains additional cartridge storage only.
v The Optional HA1 Service Bays (left 2 and right 7) contain a service area for
the accessors.

IBM 3494 Tape Library Introduction
The control unit frame provides full library function without the other optional
frames. Adding the optional frames to the control unit frame provides for additional
storage and tape drive capabilities. See Table 2 on page 25 for the cartridge
capacity of each frame.
Chapter 1. Introduction3
Functional Components
Figure 2 on page 5 and Figure 3 on page 6 show the following functional
components of the control unit frame, viewable from the front:
1 Cartridge storage cells
2 Magnetic tape subsystem
3 Rail system
4 Convenience Input⁄Output Station
|
Are located on the interior side of front doors and on the back walls of the
3494. See 1 in Figure 2 on page 5 or in Figure 3 on page 6.
The 3494 uses either the 3490E Magnetic Tape Subsystem Model C1A or
C2A, Figure 2 on page 5, 3490E Magnetic Tape Subsystem Model F1A, or
the 3590 High Performance Magnetic Tape Subsystem Model B1A, Figure 3
on page 6, with or without a 3590 Model A00 or A50 Control Unit.
The cartridge accessor is carried through the library on the rail system. The
rail system consists of two horizontal rails, one at the top and one at the
bottom.
The 3494 may have a Convenience Input⁄Output Station feature installed for
inserting or ejecting cartridges without interrupting the normal automated
operations.
Two features are available: either the ten-cartridge capacity Convenience
Input⁄Output Station as shown in Figure 2 on page 5 or the 30-cartridge
capacity Convenience Input⁄Output Station (not shown).

5 Operator panel
Note: The Convenience Input⁄Output Station feature is required for
Import/Export operations in the Model B18 VTS with the Advanced
Function Feature.
The basic operating procedures are performed from the operator panel.

Figure 3. Control Unit Frame Functional Components, 3590 (Front View)
Figure 4 on page 7 shows the following functional components of the control unit
frame, viewable from the rear:
1 Library manager
Controls all operations in the 3494. Its hardware consists of a controller,
display, pointing device, and keyboard. An optional Remote Library
Manager Console feature is also available for remote installation on a Local
Area Network (LAN) environment. During normal operations, the operator
panel controls are used to operate the 3494. The library manager is used
for error recovery, operations status, and service.
2 Cartridge storage cells
Are located on the interior side of the front doors on the 3494 and on the
back interior wall.
3 Cartridge accessor
Moves on horizontal and vertical axes, moving cartridges between the
storage cells, devices, and input and output facilities. The vision system
(barcode reader) on the cartridge accessor identifies cartridges.
4 Picker
Is the part of the cartridge accessor that actually picks cartridges. The
picker comes standard with one gripper installed or two grippers if the
optional Dual Gripper feature is installed.
5 3590 Model A00 or A50 Control Unit
is the 3590 Model A00 or A50 Control Unit.

Figure 5 on page 8 shows the functional components of the storage frame, viewable
from the front:
1 Cartridge storage cells
Are located on the interior side of the front door and on the back wall of the
frame.
2 Rail system
The cartridge accessor is carried through the library on the rail system
installed in each frame. The rail system consists of two horizontal rails, one
at the top and one at the bottom of the frame.
Figure 6 on page 9 shows the functional components of the drive unit frame with
four 3590 tape subsystems and a 3590 Model A00 or A50 Control Unit, viewable
from the front:
1 Cartridge storage cells
Are located on the interior side of the front door and on the back wall of the
frame.
2 Magnetic tape subsystems
The magnetic tape subsystems that can be installed in a drive frame are
the 3490E Magnetic Tape Subsystem Model C1A or C2A (not shown), the
3590 Magnetic Tape Subsystem Model F1A (one or two per frame), or the
3590 High Performance Magnetic Tape Subsystem Model B1A with or
without a 3590 Model A00 or A50 Control Unit.
3 Rail system
The cartridge accessor is carried through the library on the rail system
installed in each frame. The rail system consists of two horizontal rails, one
at the top and one at the bottom of the frame.
