® ™ Protec. TIER Vision and Design Criteria 1. Data-agnostic factoring of up to 25 times or more 2. Unmatched performance up to 1000 MB/s or more 3. Unequaled scalability: up to 1 PB physical data 4. Enterprise-class data-integrity: Not hash-based 5. Simple, non-disruptive deployment 6. Supported in most hardware and software environments No other dedupe technology meets all these criteria! 4 © 2011 IBM Corporation

® ™ Deduplication Algorithms - Types Content Aware Hash Based Hash Value • Assumes the best candidate to Text de-dup against is an object with similar attributes (eg file name, file type) • De-dup ratios are lower since even a tiny difference within the boundary causes the match to fail • Sepaton Protec. TIER Hyper. Factor Pointer • Hash table grows as more backup data is stored • As the repository fills, backup speeds decrease since it takes longer to check the bigger table • Eventually the Hash Table can’t fit in memory and backup speeds decrease seriously • Hence this algorithm is only suited to smaller devices: it doesn’t scale well • Data Domain, Falcon. Stor • Very fast algorithm since it processes backup stream to find possible matches then offloads work to disk to confirm the match • Algorithm can index 1 PB of physical disk using a 4 GB index that fits in memory, hence no performance degradation as the repository grows • Hence scalable for large repositories 7 © 2011 IBM Corporation
Production Customers Deployment Results ® ™ 8 © 2011 IBM Corporation
® ™ Deduplication Algorithms – Post vs Inline Post Processing Deduplication • Backups run first without de-dup • Separate de-dup algorithm runs thereafter • Requires extra disk space to hold the interim full-sized copy of the backup • Used when the de-dup algorithm is not fast enough to run inline Inline De-Duplication (eg Hyper. Factor) • De-dup runs as part of backup process • Uses less disk • Once save is done, the entire process is done • Only possible with a fast de-dup algorithm like Protec. TIER Hyper. Factor 9 © 2011 IBM Corporation

® ™ Virtual Tape on IBM i – Questions to Ask Your Vendor Overall Speed and Single Stream Speed Virtual Tape Devices shine when they can run a large number of mediumspeed backup streams. IBM i customers often need a small number of very fast streams. Be sure to understand the single stream performance provided to make sure your Virtual Tape Device will meet your needs IBM i Single Stream performance depends on the VTL disk type/amount Backup Scheduling LPAR 11 pm 11: 30 pm Midnite 12: 30 am 1 am 20 160 200 200 IBM i 01 IBM i 02 Protec.
