The IBM® TS4500 tape library is a next-generation tape
solution that offers higher storage density and integrated
management than previous solutions. This IBM Redbooks® publication gives you a close-up view of
the new IBM TS4500 tape library. In the TS4500, IBM delivers the
density that today's and tomorrow's data growth require, with the
cost-effectiveness and the manageability to grow with business data
needs, while you preserve existing investments in IBM tape library
products. Now, you can achieve both a low cost per terabyte (TB)
and a high TB density per square foot because the TS4500 can store
up to 5.5 petabytes (PBs) of data in a single 10-square foot
library frame, which is up to 3.4 times more capacity than the IBM
TS3500 tape library. The TS4500 offers these benefits: High availability dual active accessors with integrated service
bays to reduce inactive service space by 40%. The Elastic Capacity
option can be used to completely eliminate inactive service
space. Flexibility to grow: The TS4500 library can grow from both the
right side and the left side of the first L frame because models
can be placed in any active position. Increased capacity: The TS4500 can grow from a single L frame up
to an additional 17 expansion frames with a capacity of over 23,000
cartridges. High-density (HD) generation 1 frames from the existing TS3500
library can be redeployed in a TS4500. Capacity on demand (CoD): CoD is supported through entry-level,
intermediate, and base-capacity configurations. Advanced Library Management System (ALMS): ALMS supports dynamic
storage management, which enables users to create and change
logical libraries and configure any drive for any logical
library. Support for the IBM TS1150 tape drive: The TS1150 gives
organizations an easy way to deliver fast access to data, improve
security, and provide long-term retention, all at a lower cost than
disk solutions. The TS1150 offers high-performance, flexible data
storage with support for data encryption. Also, this
fifth-generation drive can help protect investments in tape
automation by offering compatibility with existing
automation. Support of the IBM Linear Tape-Open (LTO) Ultrium 7 tape drive:
The LTO Ultrium 7 offering represents significant improvements in
capacity, performance, and reliability over the previous
generation, LTO Ultrium 6, while they still protect your investment
in the previous technology. Integrated TS7700 back-end Fibre Channel (FC) switches are
available. Up to four library-managed encryption (LME) key paths per
logical library are available. This book describes the TS4500 components, feature codes,
specifications, supported tape drives, encryption, new integrated
management console (IMC), and command-line interface (CLI). You
learn how to accomplish several specific tasks: Improve storage density with increased expansion frame capacity
up to 2.4 times and support 33% more tape drives per
frame. Manage storage by using the ALMS feature. Improve business continuity and disaster recovery with dual
active accessor, automatic control path failover, and data path
failover. Help ensure security and regulatory compliance with tape-drive
encryption and Write Once Read Many (WORM) media. Support IBM LTO Ultrium 7, 6, and 5, IBM TS1150, and TS1140 tape
drives. Provide a flexible upgrade path for users who want to expand
their tape storage as their needs grow. Reduce the storage footprint and simplify cabling with 10 U of
rack space on top of the library.
This guide is for anyone who wants to understand more about the IBM
TS4500 tape library. It is particularly suitable for IBM clients,
IBM Business Partners, IBM specialist sales representatives, and
technical specialists.
