Backup System Infrastructure

Every backup environment has a bottleneck.

It may be a VERY FAST bottleneck, but it will determine

the maximum throughput obtainable with your

system.

(6)

What is deduplication ?

• Data deduplication (often called "intelligent compression") is a method of reducing

storage needs by eliminating redundant data.

• Only one unique instance of the data is actually retained on storage media, such as

disk or tape.

• Redundant data is replaced with a pointer to the unique data copy.

EMC DataDomain Mission …

Make this

(9)

(10)

Customer Example: 20x Footprint Reduction

One DD System

• 180TB stored

• 8TB of disk used

• 20x Reduction

• Replicated off-site

Red Line = Amount of data written to Data Domain (virtual storage)

Green Line = Disk Space Consumed (physical storage)

(11)

What are the reasons you do not have

de-duplication yet ?



Cost (disk is more expensive than tape)



Flexibility (only SAN support)



Performance (disk I/O bottleneck)



Data Safety & Reliability (only one copy on disk)

(12)

Many vendors offer the same – is it true ?

What needs to compared ?

• Speed (backup/restore)

• Flexibility (various protocols)

• Scalability (upgrade options)

• Supportability (IBM i, Open Systems, Mainframe)

• Simplicity (management, maintenance)

• Size (space, de-dupe ratio)

• Efficient replication (bandwidth reduction)

• Data Safety (the most important), Encryption

• Support (good people, local people)

• Cost (compare all costs)

Why EMC Data Domain for IBM i?

Feature

Benefit

Integrate with Ease and Flexibility  Data Domain presents IBM 3584-L32 tape library/libraries and LTO3

(3580-TD3) drives via fibre channel to IBM i hosts

Supportability



BRMS and IBM i Native Commands Support

Retain More Backups with

De-Duplication



As IBM i data is compressible, it is in the de-duplication wheelhouse



Store weeks of full backups on disk in a minimal footprint for rapid

database restores

Recover Data Reliably and

Efficiently



De-duplication with replication drives WAN-efficient disaster recovery



EMC’s Data Domain Data Invulnerability Architecture ensures reliable

recovery – DIA should resonate well with IBM I customers

Improve Performance



Unrivaled 8+ TB/hr aggregate and 1+ TB/hr single-stream, inline

de-duplication



Single-stream throughput capabilities are important to understand when

considering DB2 backups



Data Domain allows for greater parallelization of backup and restores

Simplify Infrastructure



Dedicate Virtual Resource to Each Application – Each LPAR can have

dedicated virtual drives

Deduplication Statistics for IBM i

• Outliers apply

–

In general the same concepts apply to IBM i environments

as any other environment in terms of data de-duplication.

• The following de-dupe ratios were discovered during

the test process:

–

Banking: 21×

–

Retail: 24×

–

Shipping: 52×

• Improve price / performance along with CPUs

• Keep price competitive with tape automation

• Alternative

–

Speed through spindle count

–

Huge amounts of wasted disk space

• Protects against loss of disk or system

–

Inline encryption provides immediate

protection while preserving deduplication

–

Works with all protocols and applications

officer role user for lock, passphrase, and

disable functions
