The tidal wave of data continues …

• The amount of digital information continues to grow exponentially• And we need to keep more of it, longer• And the costs of losing data are increasingly unacceptable

o Lost revenueso Lost customer confidenceo Embarrassment in the marketo Fines from contracts, government agencieso CEO and CFO could go to jail

• But budgets are not increasing

2005 2006 2007 2008 2009 2010

Data created and copied is expected to grow at 48% CAGR through 2010

Storage efficiency strategies and best practices


• Storage Virtualization• Thin Provisioning

• Data Compression• Data Deduplication

• Automated Tiering• Automated Data Migration

A set of essential technologies enables storage efficiency

• Move data to the right place

• Store more with what’s on the floor

• Stop storing so much


The pressures on backup administrators are growing

Backup takes longer

Recovery takes longerCan’t buy more storage

More new data coming

Growth Backup

Manage Recover


• Short Term Retentiono Use disk for daily backup

& restore operations• Performance

o Fast backupso Even faster restoreso Meet “backup windows”

• Long Term Retentiono Cost effective capacityo Removable & transportable

• Complianceo Meet financial & regulatory

requirementso Data encryption, WORM

Using the right balance of high density tapeand high performance disk will help . . .


Compression and Deduplication use less physical storage

• Store data more efficiently• Lower Operating Expenses: Power, cooling, floor space• Keep more data online for analytics and fast restores


And data deduplication is the key to using more disk more cost effectively!

Data Deduplication Overview


Deduplication Architectures

LAN SAN

ClientServer

Storage Devices

Client side• Reduce load on

server• Reduces bandwidth

on LAN• Adds load to client• No cross correlation

among multiple clients

Server side• Allows cross

correlation of data among multiple clients

• Adds load to server

Block Storage Device• Transparent to clients and

servers• Reduces load on server

and client• Adds load to storage device• No file or format awareness


Data Deduplication Process (simplified)

FEDCBA

Data Object / Stream

Identical Chunks

Assume a Data-Object or -Stream as Subject for deduplication

Data Object is split in Chunks (fixed or variable size)

For each Chunk an identity characteristic is determined

Duplicate chunks are identified• Identical Chunks are referenced with pointers,

references.• Non-identical chunks or single instances are

effectively stored• Compression may be performed in addition.

Required Disk-Cache is reduced


Methods for Data Chunking

1. File based o One chunk is one file, most appropriate for file systemso E.g. TSM Incremental Backup forever helps eliminate redundant data

– Fixed blocko Data object is split into fixed blockso Used by block storage devices

– Format Awareo Understands explicit data formats and chunk data object according to formato Example: breaking a PowerPoint deck into separate slides

– Format agnostico Chunking is based on algorithm that looks for logical breaks or similar elements

within a data object

• Chunking method influences deduplication ratio

Data Object / Stream


Method for Determining Duplicates

1. Hashingo Computes a hash (MD-5, SHA-256) for each data chunko Compares hash with all hash of existing datao Identical hash means most likely identical datao Potential (small) Risk of Hash Collisions: identical hash and non identical datao Must be prevented through secondary comparison (additional metadata, second hash

method, binary comparison)

– Binary Comparisono Compares all bits of similar chunks

– Delta Differencingo Computes a “delta” between two “similar” chunks of data where one chunk is the

baseline and the second is the deltao Since each delta is unique there is no possibility of collisiono To reconstruct the original chunk the delta(s) have to be re-applied to the

baseline chunk

In-Line Deduplication

• Data is deduplicated before it is actually stored • Deduplication is performed as data flows into the secondary storage system

• Advantageso Processes data once, eliminates additional post-processing tasks

• Disadvantageso CPU intensive deduplication process can create performance bottlenecko One process per I/O stream

VTLBackup


Out-Band Deduplication (Post-Processing)• Data is first stored and deduplicated in the background

• Advantageso De-duplication CPU overhead no longer affects backup windowo Supports multiple I/O streamso Potentially faster restore for first version (not deduplicated)

• Disadvantageso Data is written, read and written – thus more I/O intensiveo Deduplication window must be coordinated with backup window as it take

typically longer than in-line processingo Requires larger secondary storage because first version is not deduplicated

IBM’s Virtual Tape De-duplication SW Products

• HyperFactor

• ProtecTIER ProtecTIER VT is a scalable and robust virtual tape solution that emulates

tape libraries, enabling existing backup applications to send data to the ProtecTIER disk-based platform, rather than directly to tape.

HyperFactor is a revolutionary de-duplication solution which eliminates redundant data, enabling customers to increase their effective capacity by up to 25 times. ProtecTIER is powered by HyperFactor and can radically reduce both physical disk capacity and total storage costs.

How ProtecTIER works


• Backup application writes data to ProtecTIER as it would to tape

• Only unique data is stored, existing duplicate data is referenced

• When data objects expire, references are removed and free space is reclaimed and reused

ProtecTIER Differentiation


ProtecTIER Advantage: Data Integrity

• Unique and patented HyperFactor® deduplication technology

• The only production proven deduplication solution not based on a hash algorithm

• Designed for 100% data integrity• Bit for bit comparison of data to ensure data is a

duplicate• Can NEVER lose data due to a hash collision

Although the chance of losing data from a hash collision is low, it is NOT ZERO as it is with a ProtecTIER solution


ProtecTIER Advantage: Restore Performance

• Restoring data from a ProtecTIER solution is even FASTER than backing up

• ProtecTIER can easily restore at 2800MB/sec!• High restore performance not limited to certain backup

applications or specific data sets like other vendors• High restore performance achieved on real data with

realistic 20% change rate in production environments• Never requires agents on backup servers

Other vendor’s “CPU-centric” architectures are optimized for processing hashes not moving data


• A single ProtecTIER system can support up to 1 Petabyte of useable capacity

• ProtecTIER supports the use of any IBM storage system (DS8000, DS5000, XIV, etc.) and most third party storage systems for the repository

• IBM has hundreds of ProtecTIER systems with over 100TBs of useable capacity in production environments throughout the world

• IBM always states “Useable Capacity” and never uses the deceptive “RAW capacity” terms like other vendors

The hidden costs associated with managing, maintaining, poweringand cooling multiple appliances is significant and should not be ignored!

ProtecTIER Advantage: Scalability


Many vendors claim to have Global Deduplication but create multiple separate repositories that may contain redundant data!

ProtecTIER Advantage: Global Deduplication• ProtecTIER Cluster with true Global Deduplication has been

Generally Available and in production since 2008• Supported with all major backup applications and available for

all Open Systems, System z and System I platforms• No agents or backup server upgrades required• Other vendor’s Global Deduplication capabilities are immature

and incomplete with very few if any systems in production• Other vendor’s Global Dedupe restricted to certain models,

only with NetBackup OST and require agents to be installed
