The Value of Tape and a Tiered Storage Hierarchy

ATA DiskSystem

LTO TapeLibrary

HybridDisk&Tape

* Source: Data Mobility Group , Research Study, July, 2004

7 year TCO to manage 50TB – including acquisition and power*

� Tape is intrinsically “On-Demand”

� Tape is removable and portable for optimum data pro tection

� Tape is infinite capacity… .just add more cartridges

� Tape media has a long life

� Tape is low cost

Customers require fast access to data as well as lo w costs:A tiered hybrid solution that integrates disk and t ape may address both




Tape Drive Selection Criteria

� LTO

� Open system attachment

� High capacity

� Data streaming applications

�Write Intensive applications

� Legacy technology

�WORM requirement

� 3592

� zSeries and Open attach

� High capacity & fast access

� Start stop applications

� High recall rate

� Legacy technology

�WORM requirement

� Silo attach




Surface Control Guidingprevents servo damage at end of tape

Magnetoresistive Flat Lap Headprovides better control of tape

Reduces tape wear, increasing reliability and durability

ProblemSome data is incompressible (e.g. encrypted or previously compressed data)In some cases, compression of incompressible data may actually expand the data stream

IBM Solution: Dynamic Compression Look-AheadIn situations where compression is enabled, Dynamic Compression Look-Ahead ensures the input data stream being written to Tape is not automatically expanded by the ALDC (Adaptive Lossless Data Compression) algorithmAny incompressible data stream will be redirected around the compressor

This method thus optimizes compression and maximizes cartridge capacity

Dynamic Compression Look-Ahead IBM industry leading

Product Overview

LTO Ultrium Tape Drives




IBM LTO Gen 3 Offering Highlights� Improved reliability

� Improved productivity and infrastructure simplification

�Reduced heat and operation costs

�Reduced handling and space consumption

� Improved business flexibility




IBM LTO Generation 3 – Technology Highlights� Increased rate up to 80MB/s native - via 16 track writing & increased linear density

� Increased capacity up to 400GB uncompressed - via additional tracks and track density to help reduce handling and space consumption costs

� New dual stage 16 channel head actuator - designed to provide precision head alignment to help support higher track density and improved data integrity.

� New independent tape loader and threader motors and positive pin retention -designed to help improve drive reliability.

� Graceful dynamic braking - In the event of power failure, motors are designed to gradually decelerate helping reduce breakage, stretching, or loose tape wraps.

� Larger internal buffer - the internal buffer size has been doubled over the Ultrium 2 (64MB) to 128 MB helping to improve streaming performance.

� Highly integrated electronics using IBM copper tech nology - designed to reduce components & power consumption, lower chip temperatures for more reliability
