IBM TS4500 R8 Tape Library Guide

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 requires. It has the cost-effectiveness and the manageability to grow with business data needs, while you preserve investments in IBM tape library products.

Now, you can achieve a low per-terabyte cost and high density, with up to 13 PB of data (up to 39 PB compressed) in a single 10 square-foot library by using LTO Ultrium 9 cartridges or 11 PB with 3592 cartridges. The TS4500 offers the following benefits:

• Support of the IBM Linear Tape-Open (LTO) Ultrium 9 tape drive: Store up to 1.04 EB 2.5:1 compressed per library with IBM LTO 9 cartridges.
  
• High availability: Dual active accessors with integrated service bays reduce inactive service space by 40%. The Elastic Capacity option can be used to eliminate inactive service space.
  
• Flexibility to grow: The TS4500 library can grow from 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 another 17 expansion frames with a capacity of over 23,000 cartridges.
  
• High-density (HD) generation 1 frames from the 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 IBM TS1160 while also supporting TS1155, TS1150, and TS1140 tape drive.
  

• Integrated TS7700 back-end Fibre Channel (FC) switches are available.
  
• Up to four library-managed encryption (LME) key paths per logical library are available.
  

You learn how to accomplish the following tasks:

• Improve storage density with increased expansion frame capacity up to 2.4 times, and support 33% more tape drives per frame
