IBM Linear Tape File System Enterprise Edition V1.1 (LTFS EE) was announced on June 10th at Edge2013 in Las Vegas. To help launch the product we published the draft : IBM Linear Tape File System Enterprise Edition V1.1 Installation and Configuration Guide, SG24-8143. LTFS EE for the IBM System Storage TS3500 Tape Library provides seamless integration of LTFS with IBM General Parallel File System (GPFS) by creating an LTFS tape tier. LTFS EE can play a major role in reducing the cost of storage for data that does not need the access performance of primary disk.
This IBM® Redbooks® publication helps you with planning, installation, and configuration of the new IBM Linear Tape File System™ (LTFS) Enterprise Edition (EE) V1R1 for the IBM System Storage® TS3500 Tape Library. LTFS EE is designed to enable the use of LTFS for the policy management of tape as a storage tier in a IBM general parallel file system-based
(IBM GPFS™) environment and helps encourage the use of tape as a critical tier in the storage environment.
LTFS EE can run any application designed for disk files on tape. LTFS EE supports IBM Linear Tape-Open (LTO) Ultrium 6 and 5 tape drives, and IBM System Storage TS1140 Tape Drives installed in TS3500 tape libraries. Using LTFS EE to replace disks with tape in Tier 2 and Tier 3 storage can improve data access over other storage solutions as it improves efficiency and streamlines management for files on tape. LTFS EE simplifies the use of tape by making it transparent to the user and manageable by the administrator under a single infrastructure. Figure 1 shows the overview of the LTFS EE archive solution.

Developing Redbooks pre GA can be exciting and challenging with all the last minute updates. When we decided to have the LTFS EE Redbooks publication ready for announce we knew we would have to work closely with development so we ran the residency in Tokyo where the development team is located. The team led by Ishimoto-san was incredibly helpful in providing the resources and answering our questions while we were writing the book. Here is a picture of our residency team outside the IBM Tokyo lab. They also took us to some great restaurants. The cherry blossom festival was at its peak when we arrived and lasted through most of our residency. The light pink in the background is what was left of the blossoms when we ended the residency mid April.
