11 Why IBM De-duplication IBM s capability to integrate Virtualization and Data de-duplication IBM s unique capability to leverage key acquisitions - Diligent Over 30 years experience with storage virtualization IBM s plans to deploy De-duplications across the storage portfolio Complete range of skills to support De-duplication across the enterprise Implementation with Virtual Tape, Tivoli Storage Manager, and N series Integration of Software, Disk & Tape for tiered storage IBM s Data De-duplication Offerings Virtual Tape De-duplication IBM System Storage TS7650G ProtecTIER De-duplication Gateway Virtualized Tape and De-duplication for the Enterprise Software De-duplication Tivoli Storage Manager (TSM) Extended Edition V6.1 De-duplication within the Backup/Recovery application Network Attach Storage De-duplication N series advanced Single Instance Storage (A-SIS) De-duplication for IBM NAS offerings 11

12 IBM TS7650G ProtecTIER De-duplication Concepts Changing the Data Protection Game Protect More Store Less ProtecTIER reduces the required backup disk capacity by up to 25X s or more 12

13 TS7650G ProtecTIER Overview Virtual Tape Library FC Backup Server TS7650G Disk Array Software solution that resides on standard Linux server Emulates a tape library unit, including drives, cartridges and robotics Uses FC-attached disk array as the backup medium Protect More Store Less TM Represented capacity Master Server Backup Server ProtecTIER Server Physical capacity Up to 25X the physical capacity 13

14 Real World Impact of HyperFactor Telecom Nominal Data Protected (TB) 190 Physical Capacity (TB) 13 Retailer Financial Manufacturing TS7650G ProtecTIER De-Duplication Gateway, Clustered FC Switch TS7650G x 2 2 Node Cluster Backup Servers Active-active true clustered nodes High performance (900MB/s sustainable) Highly available Backup Arrays High capacity, highly scalable Easily manageable Two nodes working together One repository 14

15 ProtecTIER Vision and Criteria: 1. Data-agnostic factoring of up to 25x 2. Enterprise Class inline performance: 450 MB/s per one nodes (can up to 900 MB/s) 3. Unmatched scalability: 1 PB physical data % data-integrity during de-dupe process 5. Simple, non-disruptive deployment 6. Software-only solution: hardware agnostic No other Most de-dupe elements of technology new-data backed meets up all today these criteria! already exist in previous backups New Data Stream Repository Memory Resident Index FC Switch TS7650G Disk Arrays Backup Servers Ratio of Repository to Index: 250,000 : 1 Filtered data 15

17 De-duplication Technique : Three Basic Approaches HyperFactor A different approach based on an agnostic view of data Hash based de-duplication Sometimes referred to as a Content Addressable Storage approach Content Aware Assumes the best candidate to de-dupe against is an object with the same properties (name etc.) HyperFactor Approach 1. Look through data for similarity New Data Stream 2. Read elements that are most similar 3. Diff reference with version will use several elements Element A Element B Element C 4. Matches factored out unique data added to repository 17

18 Hash Based Approach 1. Slice data into chunks (fixed or variable) A B C D E 2. Generate Hash per chunk and save A h B h C h D h E h 3. Slice next data into chunks and look for Hash Match A B C D E 4. Reference data previously stored Content Aware Approach 1. Look through data for fully qualified file names File A File B File C File D 2. Locate previous version of file File A extents 1,2,3,4 3. Compare reference with version File A File B File C File D 4. Update reference to point to new reference 18

19 Hash and content aware de-duplication approaches require a tradeoff between compression and performance Because of HyperFactor s breakthrough approach, ProtecTIER does not have this fundamental limitation De-Dupe/ Performance Frontier De-Dupe Ratio ProtecTIER TB Performance/Scalability PB 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 19

20 Step 1: Index Lookup HyperFactor Memory access even when scaled to PBytes Processing 10 TB requires only RAM-based index searches index search is never a bottleneck Hash Based Given average of an 8 KBytes data slice per fingerprint Requires 1,250,000,000 accesses to an Index to process 10 TB a major bottleneck Content Aware File size dependant Given average file size of 1 MByte requires 10,000,000 accesses to an Index to process 10 TB- a major bottleneck Step 2: Backup Payload Processing Example of How Disk Sees De-Dupe For 10 TBytes Output 1 HyperFactor Inline 10 TB Output HyperFactor Read 10 TB 1x Computational Difference 2 Hash Based Inline 10 TB Output Hash Based 0x 20

21 Step 2: Backup Payload Processing Example of How Disk Sees De-Dupe For 10 TByte Output 3 Hash Based Post Process 10 TB Output Hash Based Write 10 TB Read 10 TB 2x 4 Content Aware Post Process 10 TB Output Content Aware Write 10 TB Read 10 TB Read 10 TB 3x Computational Difference Combining I/O Activity for 10 TBytes Approach I/O Accesses to Index Disk Payload (TBytes) HyperFactor Hash Inline Hash Post Content Aware 0 > 1 Billion * > 1 Billion ~10 Million * This can be hosted in memory if the mapped area is small. When dealing with a 10 TByte payload this is not likely. 21

22 Is There a Meaningful Difference? Time Will Tell! Case Study: Impact of Different Post-Process De-dupe Speeds Profile Receive at 300 MB/s Post 100 MB/sec Backup 6 TB Takes approximately 6 hours Post process then consumes the next 18 hours! So, it takes 24 hours to process 6 TB 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? Actual performance: 6 TB / 24 Hrs = 69.4 MBPS 22

23 Inline Processing Backup Server ProtecTIER VT Tape Library Truck De-Dupe SLA is Met 8:00 PM 2:00 AM 8:00 AM 8:00 PM Post Processing De-Dupe Overlap Backup Server VTL Tape Library Truck De-Dupe De-Dupe 8:00 PM 2:00 AM 8:00 AM 8:00 PM Post Process Performance Calculations Both the ingest rate and the de-duplication rate must be considered in assessing true performance Vendors claim high throughput for the ingest rate, but ignore the post process window Example: Post Process de-dupe of 6 TB Ingest 6 hours Vendor claims 300 MBPS performance De-dup 18 additional hours* but vendor neglects the post process window Actual performance: 6 TB / 24 Hrs = 69.4 MBPS 23
