IBM Linear Tape File System Enterprise Edition V1.1 Installation and Configuration Guide

Book Description

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 an 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 that is 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 that are installed in TS3500 tape libraries.

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. The use of LTFS EE to replace disks with tape in Tier 2 and Tier 3 storage can improve data access over other storage solutions because 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.

This publication is intended for anyone who wants to understand more about LTFS EE planning and implementation. This book is suitable for IBM clients, IBM Business Partners, IBM specialist sales representatives, and technical specialists.
