“We believe tape encryption with LTO-4 products has the potential to become ubiquitous. Just like data compression, users can turn it on and let it do its magic.” Heidi Biggar, Enterprise Strategy Group,

September 2007



Value of the IBM Encryption Solution Highest Level of Security

– Layered Architecture uses RSA2048 Asymmetric KeyPairs to wrap Data Key for secure transmission site-to-site and business-to-business

– Leverages FIPS 140-2 Compliant Environments for Secure Key Management

Highest Degree of Flexibility– May be deployed Cross-Enterprise (Open, SystemZ)– May be deployed as a standalone Encryption Solution, or integrated

with existing Cryptography Applications (SSL, PKI Services, DB2/IMS Encryption, Planned Disk Encryption)

Simplest Administration– Use existing security infrastructure– One EKM can manage cross-platform and mixed device requirements

Lowest Total Cost of Ownership– Tape Drive Savings– Maintenance Savings– No Charge for EKM– No special appliances

TS3100 / TS3200 New HVEC Structure

Beginning September 4th, the Tape Libraries will be available in driveless configurations

Orders will now require two step process with two different part numbers : one for Tape Library + one for Tape Drive

Two new part numbers for the Tape Libraries will announce as follows:

– IBM System Storage TS3100 Tape Library Model L2U Driveless : 3573 2UL

– IBM System Storage TS3200 Tape Library Model L4U Driveless : 3573 4UL

For full functionality, the TS3100 and TS3200 Tape Libraries Driveless models require IBM LTO Ultrium Tape Drives. Part numbers for Ultrium 3 or Ultrium 4 Tape Drives remain unchanged: 95P5002, 95P5004, 95P5006, 45E2243, 23R7260, 23R7261, 95P4998, 95P5000

What They are Saying About Tape

“We ask…would (you) make the same (tape library) purchase decision again. IBM had the highest positive response in both the enterprise (84.3%) and midrange (82.1%) categories.” Storage Magazine, Quality Awards III, March 2008

“IBM ranks highly on a vision and execution basis (with the TS7700 Virtualization Engine). It has listened well to the market and responded with an up-to-date solution. IBM is well positioned today and for the future. The Tod Point Group, Nick Allen, High-End Virtual Tape: IBM Leaps Ahead with a New Grid Architecture, March 2008

“An offline tape is as “green” as it gets since no power or cooling is required for tapes that are offline. For most IT shops, a blend of disk and tape appears to be the strategy of choice for the foreseeable future.” The Mesabi Group, David Hill, Sense and Sensibility about Tape and Disk, March 2008

“The cost ratio for a terabyte stored long-term on SATA disk versus LTO-4 tape is about 23:1. For energy cost, it is about 290:1. Tape continues to provide the fiscal responsibility and functional value that enterprises require in the twenty-first century.” The Clipper Group, Disk and Tape Square Off Again, Report #TCG2008009LL, Feb 2008

"IBM’s (TS1120) flexible (encryption) key management, tape drive attributes and lower pricing win the race (vs Sun T10000).” The Tod Point Group, Nick Allen, Tape Encryption: A Must in Today’s World-IBM and Sun Square Off, July 2007

A Simple View of the Backup Process

Data is Off-site



Three Basic Approaches

Talked about today in the industry:

1. Hash based de-duplication

– Sometimes referred to as a Content Addressable Storage approach

2. Content Aware

– Assumes the best candidate to de-dupe against is an object with the same properties (name etc.)

3. HyperFactor

– A different approach based on an agnostic view of data



Hash Based Approach

1. Slice data into chunks (fixed or variable)

2. Generate Hash per chunk and save

3. Slice next data into chunks and look for Hash Match

4. Reference data previously stored

A B C D E

Ah ChBh Dh Eh

A B C D E



Content Aware Approach

1. Look through data for fully qualified file names

2. Locate previous version of file

3. Compare reference with version

4. Update reference to point to new reference

File A File B File C File D

File A extents 1,2,3,4

File A File B File C File D



HyperFactor Approach

1. Look through data for similarity

2. Read elements that are most similar

3. Diff reference with version – will use several elements

4. Matches factored out - unique data added to repository

New Data Stream

Element A Element B Element C



De-dupe Design Considerations

Redundant Data Elimination

– The grain of redundancy, 8KB, 1 MB or …

Performance

– Performance battles with Capacity

– Performance is challenged/curtailed by disk i/o

Capacity

– Backup to disk has to cope with 100’s of TBytes

– All designs can grow in capacity… but many do so at the cost of performance



Two Basic Implementations

1. Inline

– As data is received by the target device it is

• de-duplicated in real time• not temporarily stored on disk

– Data written to the disk storage is de-duplicated

2. Post Processing

– As data is received by the target device it is

• temporarily stored on disk storage– Data is subsequently read back in to be processed by a de-

duplication engine



Performance Considerations

For all de-dupe approaches, performance is the result of two processes:

– Identification of duplicate data—requires a database or index look up

– Backup payload processing

The combination of the two processes yields the overall de-dupe performance

For each de-dupe method, we’ll look at both processes independently when handling 10 TBytes



Step 1: Index Lookup

1. HyperFactor™

– Memory access even when scaled to PBytes

2. Hash Based

– Given average of an 8 KByte data slice per fingerprint

– Requires 1,250,000,000 accesses to an Index to process 10 TBytes

3. Content Aware

– File size dependant

– Given average file size of 1 MByte requires 10,000,000 accesses to an Index to process 10 TBytes



Step 2: Backup Payload ProcessingExample of How Disk Sees De-Dupe For 10 TByte Output

Is There a Meaningful Difference?



Impact of Different Speeds

Receive at 300 MB/s

Post Process @ 100 MB/sec

Backup 6 TB

– Takes approximately 6 hours

Post process then consumes the next 18 hours!

But

What about resources in support of vaulting/off-site

When de-dupe is a post-process it competes for disk resources as any other process

ProtecTIER Deduplication Appliance List Price Reductions

Enabling Business Partners and IBM sellers to compete and win without needing to special bid



ProtecTIER Appliance List Price Reduction

The Problem

– The Street Price of the Appliance is competitive, the List Price is perceived as high compared to the competition

IBM listened to . . .

– Business Partners - Although our solution is better, BPs commented about the effort required to get to a competitive street price

– Analysts and Press – Regularly praised the power of ProtecTIER but warned about the high price based on misconception that List Price is close to street price

– IBM Sellers – Commented that our high List Price often knocked ProtecTIER out of considered before merits of solution could be articulated



ProtecTIER Appliance List Price Reduction

and IBM responded with lower list prices on all 4 configurations

• 7TB ProtecTIER Appliance – 100MB/sec performance– Old List Price - $278,485– New List Price - $146,469



• 36TB HA ProtecTIER Appliance – 500MB/sec w/ High Availability– Old List Price - $934,325– New List Price - $606,013

New Lists Prices reduce effort and time required to get to competitive street price!

LTO Sales Strategy

Use the ‘silver bullet’ strategy

– IBM tape drive leadership

– LTO Gen 4 leadership

– IBM Encryption

– CPF/DPF

‘Gotchas’

– IBM does not have a LTO Gen2 offering

– Quantum will lead with cartridge density

– HP has dual ports on their LTO Gen 3

– HP will compete on price
