HD2 frames can be installed in the leftmost library position (frame position 1) and
offer drive-capable models that support up to 16 HD2-compatible tape drives when
in frame position 2 or higher.
Note:
Non-HD2 frames cannot be upgraded to HD2 frames.
TS4500 tape library delivers high performance
The IBM TS1060 LTO Ultrium, IBM TS1050 LTO Ultrium Tape Drives, and TS1140
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,
helps enhance performance even further. The TS4500 tape library is designed for
high data transfer performance.
Cartridge move time within the TS4500 tape library can be as fast as 3.0 seconds
or less in a single-frame library. The dual-gripper accessor is designed to retrieve
the next cartridge to be mounted, unload the current cartridge, and load the next
cartridge, helping provide the following potential benefits as compared to a single
gripper:
• Save complete move operations
• Improve overall library performance
• Increase redundancy and reliability
TS4500 tape library defines high reliability
Leading-edge technology positions the TS1140, TS1060 LTO Ultrium, and TS1050
LTO Ultrium Tape Drives among the top leaders of the industry. 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 Magneto Resistive
(MR) heads, designed for accuracy, high reliability, and durability. The TS4500 drives
and library robotics are TapeAlert-compatible, and are designed to provide tape
drive and library errors, 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 address a wide variety of customer
requirements. You can attach up to three Model D25 or D55 expansion frames to a
Model L25 or L55 base frame to tailor the library to match your system capacity and
performance needs. This provides a cartridge capacity with Ultrium 6 data cartridges
of up to 4,690 cartridges with up to 11.7 PB of physical capacity per library (up
to 29.3 PB with 2.5:1 compression), or with 3592 data cartridges of up to 3,550
cartridges with up to 14.2 PB of physical capacity per library (up to 42.6 PB with 3:1
compression).
Model L25 (base frame)
TS4500 tape library Model L25 is a base frame designed for TS1140 or 3592 Tape
Drives and 3592 data cartridges. The Model L25 base frame has up to 660 cartridge
slots (up to 550 in frame 1) and support for up to 16 tape drives (up to 12 in frame
1). Up to 16 logical libraries (one per tape drive) can be configured for each frame.
Each Model L25 library has two standard 16-slot cartridge I/O stations for importing
or exporting 3592 tape 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 is designed
to scan the cartridge labels enabling a re-inventory of the cartridges in the library
frame in as little as 60 seconds. A door lock is included to restrict physical access to
cartridges in the library.
Model L55 (base frame)
TS4500 tape library Model L55 is a base frame designed for IBM TS1060 LTO Ultrium
Fibre Channel, IBM TS1050 LTO Ultrium Fibre Channel Tape Drives, and LTO data
