Industry Trends – Data footprint growth More data being stored, copied, backed up, protected Sparse, Duplicate Files and Content Original Data. Copies – Data proliferation and expanding data Primary Database, DSS, Training, Test, Backup, BC, DR, HA, Email, File serving Dev QA, Operational, Archive, Compliance Needs In addition to storage space capacity, App-a App-b App-c IOPS and MBPS to move data needs to be considered. 10 TB 8 TB 2 TB RAID 1+0 RAID 1 RAID 5 10 TB 8 TB 2 TB 8 TB Multiple data footprint by data protection factor (e. g. RAID level and mirroring) along with spares and free space to account for actual disk space 10 TB 10 TB 10 TB 8 TB 2 TB 8 TB 2 TB 8 TB 2 TB Challenge: More data to back up, protect and manage Solution: Reduce footprint impact: Archive, compress, dedupe, tiered storage See “Business Benefits of Data Footprint Reduction” www. storageio. com Source: “The Green and Virtual Data Center” (Auerbach) © Copyright 2008 Storage. IO Group All rights reserved. www. storageio. com

Hot Storage Topic – Data Footprint Reduction Archiving, compress (on- and off-line), deduplication • Develop an overall data footprint reduction strategy – Address online primary, secondary and off-line data – Combine archiving, compression and dedupe in strategy • Archiving and pruning with data classification – Database, email, unstructured block and file – Big benefit, costly to deploy (people, hardware, software) • Compression for online and off-line storage – Can be applied to most any data type for some benefit – Online real-time compression for active primary data • Single Instance Storage (SIS) and deduplication – Initially targeted at backup and archive – Look into scaling capabilities and claims by vendors See “Business Benefits of Data Footprint Reduction” www. storageio. com © Copyright 2008 Storage.

General Comments Basic premises – gain management insight and control • Look beyond consolidation to enable and sustain growth – Be in position to support future growth. It’s just a matter of time! • You can’t go forward if you can’t go back! – Time to re-architect data protection, BC and DR with new techniques. • You can’t delete what you have not preserved – Assuming customer data has some value, preserve before deletion. • Archiving is for more than regulatory compliance purposes – Implement tiered storage, boost performance, address PCFE. • You can’t manage what you or your customer don’t know about – Identify what data, files and objects you have: insight. e at www. storageio. com and www. thegreenandvirtualdatacenter. com © Copyright 2008 Storage.

Closing Comments Basic premises – gain management insight and control • Many approaches depending on your customers’ issues – Help customers do more with what they have to sustain growth – Help customers shift from energy avoidance to energy efficiency • Avoid simply moving IT problems around – Help your customers gain control of data and infrastructure issues – Solve problems and issues to enable your customers to grow • Instead of race to replace tape, revamp data protection architecture • Instead of race to consolidate data centers, enable remote management • Balance between future and what works today – Leverage what works and what customers are buying – Land sales and revenue on shipping products while selling the future – Help your customers develop strategies for moving forward © Copyright 2008 Storage.
