Storage Professionals’ Pain Points


�Protection of data

�Data is copied to another media,

original data are being kept on disk

�Restore means data loss!

�All updates after the last backup are lost

�Recovery is required (redo-logs)

� Long-term data retention

� Original data is moved

� Efficient archive search capabilities

are required

� Archive does not replace backup!

� Archived data need to be backed up,too

� Retention and compliance regulations

Backup ArchiveInformation Retention

Information Availability


A backup solution consists of

� Backup policies

� One or more backup products– TSM, BRMS etc from IBM– Symantec Netbackup/BackupExec, EMC Networker, HP Data Protecter, Microsoft DPM,

…

� Integration with server applications as needed– E.g. TSM for DP, Mail, TSM FlashCopy Manager

� Enabling disk functions for fast backup/restore

� The most cost efficient storage hierarchy that fulfills the customer’s Service Level Agreement– Disk and/or– Virtual tape and/or– Physical tape

� Consulting services

� Migration services

� Implementation services


An archive or retention solution consists of

� Archiving policies

� One or more archiving products– IBM Content Collector, Content Manager, TSM HSM, …– ISV products

� The most cost efficient storage hierarchy that fulfills the customer’s Service Level Agreement– Disk and/or– Specialize archiving appliance (Information Archive, DR550)– Virtual tape and/or– Physical tape

� Consulting services

� Migration services

� Implementation services


If you only sell a hammer, every problem is a nail:

� Disk-only vendors have only one storage technology to offer: disk!– Disk / VTL solution

+ Performance+ RTO & RPO+ Compliance- Data Protection- Costs / TCO- Relaibility

� Tape-only vendors have only one storage technology to offer: tape!– Tape

+ Compliance+ Security+ Data protection+ TCO - Performance

� To meet all goals: Blended Solution– Combination of Disk+Tape+VTL+Dedup– Depending on the customer requirements– We can do it all – tailor made– Plus SW, plus services

Disk vs tape

� Disk technology: only moderate improvements in speed and latency– Growing needs for streaming analytics, requires high IOPS– Growing need for massive digital data archival, requires low TCO

� Solid-state memory technology is addressing the high IOPS segment more efficiently than disk

Currently Flash technology: What will come after Flash?

� Tape has addressed, so far, the low TCO segment more efficiently than disk

Can it maintain its substantial cost/GB advantage over disk?

� Tape is low cost, green, excellent density/sqm, portable, secure, compliant

� IBM has tape solutions from desktop units to robots with more than 20,000 slots and up to 192 drives

� “self describing tapes” are being developed (first step = LTO5)


Reduce your Storage infrastructure by up to 25 times reducing floor space, energy and cost!

� Up to 10 times improvement in data recovery times

� Eliminates tape operators and tape handling

� Eliminates physically shipping cartridges for offsite archive

� Provides the performance of disk backup at the cost of tape

�100% Data Integrity

Disk Based Backup and Recovery priced competitively with tape!

Protect More. Store Less: ProtecTIER


What does ”up to 25 times mean”

� Assume I make 1 full backup per week for 4 weeks

� And 1 full backup per day for 7 days

� Then I need to have 4 + 7 = 11 logical versions of my data in my backup storage

� Full backups may/will contain data unchanged since last backup

� How much unique data do I need to store?

� Storing unique data only = deduplication

� This deduplication can happen in– Software (e.g. incremental for ever, DB/mail agents)– Hardware

• Compression en route to backup device • Deduplication in device

� Can the same data be deduplicated twice?– Sure, e.g. once in the backup server and once across servers

� But you cannot get the total benefit twice!


What makes a good deduplication candidate?

� Many full backups vs incremental backups

� Low data change rate – Data can change because of

• ”organic” data change• Operational procedures, e.g. frequent reorganizations of databases

� No ”messing around” with data– Source encryption, compression not good for dedup

� TSM with client compression, incremental forever, lots of DB and mail agents might not be the best candidate

� Backup solution with full backups etc would be excellent candidate– BRMS, ISV backup products

� Archive data is probably not a good candidate


Is deduplication the only argument for virtual tape?

� Certainly not!

� Restore time is faster at least for smaller amounts of data

� LAN free backup solutions work much better with VTL (can save lots of physical tape drives)


IBM Deduplication Products

� HW (virtual tape):– TS7610 Appliance Express (open distribution) up to 5TB capacity after dedup– TS7650 Appliances up to 36TB– TS7650G Gateway up to 1PB– TS7680G Gateway for z/OS up to 1PB– Entry to enterprise class performance, availability, reliability– Inline deduplication, no server performance impact

� HW (other)– N Series ”post processing dedup” of all data– Some performance impact

� SW– TSM v6 post processing dedup– Some performance impact

Introducing IBM Information ArchiveNext Generation Information Retention Solution

A universal, scalable, and secure storage repository for structured and unstructured information

A fully integrated archive appliance

Addressing the complete information retention needs of mid-size and enterprise clients

Application support including IBM ECM and Optim with policy harmony

Announced Oct 6, 2009Pricing & Availability update Jan 26, 2010General Availability Feb 5, 2010


What is cool about IA?

� Compliance (SOX etc) functionality

� Integrated TSM server

� Backend tape attachment supported

� Compared to a TSM server and disks and tapes:– Compliant– Turn key solution

� But of course, TSM and disks and tapes is an option, there has to be a business case

� Most often that business case will be driven by compliance needs!


Your opportunity:

� Sell from biggest storage portfolio available (SSD, disk, virtual tape, tape, IA)

� Combine with servers for backup and archiving

� Combine with IBM SW solutions

� Or offer open solution tested with ISV SW

� Technologically leading portfolio

� And add your own knowhow, expertise, market knowledge


Where we need your help

� Spread the messages:– The most complete solution = the IBM solution– Customers should have the widest choice possible, no vendor lockin– Tape is definitely not dead– VTL, IA etc YES we have the best solutions if the customer needs them

� Identify the opportunites– Customers with good dedup potential (incl non-TSM customers)– Customers with archiving needs– Customers with uncontrolled storage costs

� Use all IBM– STG – SWG– MTS– IGF– Competitive information
