3. Agenda • Welcome and Introductions • File Virtualisation / Data Mobility – The Problem • File Abstraction – Options • A Customer Case Study • The Business Case • Use Cases – How is Acopia Used? • Technical Overview • Demonstration • Summary and Discussion

4. Think about the daily commute: Most of these people will get given a PC to access Applications Applications create files Files have to be stored somewhere Each file consumes data storage Applications / users are becoming more sophisticated Files are getting bigger Organisations must retain and protect MOST information created.

5. Changing World of Files • 8 MPixel Camera – 16 GB SD Card – 4000 Files • 20 GB IPod - ? Files • CCTV – 4 Frames per Second – 7x24 • 240 Files Per Minute • 240 x 60 x 24 x 7 = 2,419,200 Per week • 125.8 Million Files PA • Office Files … just how many on your PC?

6. A few Customer stats… 8,600,000 email files – grown by 2,300,000 in 3 months! 55,000 home drives 1,113+ shared drives 1,100,000 duplicates 50TB+ of data 53,000,000 Office Docs - grown by 11,000,000 in 3 months! Largest file is 16GB 73% not modified >6 months

7. Value Proposition: File Virtualization Direct Attached Storage Networked Storage Virtualized Storage Islands of Storage Unified Storage Isolated Storage Simple Management Complex Management OPEX Massively Scaleable Limited Scale CAPEX Online Data Management Disruptive Data Management OPEX Increased Utilization Poor Utilization CAPEX Tiered Storage Cost vs. Data Value CAPEX

8. File Virtualization Global Presentation Namespace Clients & Applications • Persistent “proxy” that provides location independence for access to physical file storage • Non-disruptive, simplified storage management • Network-based technology • Leverages existing infrastructure • Does not require additional SW / agents • Uniquely scales • Pools together resources in Real Time for better aggregate scale and performance • Load balances across servers • Scales across the enterprise • Across switches & sites • Acopia’s ARX is unique in its ability to provide these functions File Virtualization Switch Network Storage Servers

9. Impact: Explosion in amount of file data File-based storage increasing by over50% IT budgets are flat “80% of budget keeps the lights on” Declining storage costs Cost of disk storage systems is declining >30% annually Increasing density Cost of managing storage outweighs acquisition costs Terabyte Growth Budget $/Terabyte Cost The Enterprise IT Organisation must do something different to manage this data

10. Data from IDC 2007/2008 TB Growth >50% in EMEA $/GB continues to fall by approx. 33% pa All Growth is in Unstructured data Top 3 Applications for Storage Use Email File Sharing Data Archiving 1TB decommissioned for every new 4TB Meaning: ½ Exabyte needs migration this year in Western Europe

11. Data Assessment: Content Heavy: Email/Excel/Word/PPT File and Print Document Sharing and Transactional 5% of data is 0-30 days old 20% of data is 30-90 days old 75% of data is 180 days old Findings: You are backing up and archiving the same data over and over again • File Servers or email Servers at High Utilization • Large Amounts of Duplicate Files • No File Management Understanding the Data Growth

12. Some Client Statistics: Storage Projected growth 1500 TB by end of 2007 Encompasses SAN, NAS and CAS Represents raw SAN capacity / usable NAS capacity Represents average increase of 105% pa! All used storage is backed up to tape and stored offsite

13. Client: Statistics - Backups 13 separate environments globally 1100 clients globally backed up Local server data as well as Storage is backed up Represents average increase of 82% pa 40000+ tapes collectively stored offsite

14. Engineering Company – Files Not modified in 180 Days

15. Current File Usage at a Bank Top 10 File Extensions Used (GB) Total Capacity Statistics

16. File Usage with Tiering Tiered Storage Report Capacity Used (GB) - Age on Modify Time Tiered Storage Report Files - Age on Modify Time

17. Summary – The end result

20. FAN = File Area Network • A FAN enhances standard network and storage infrastructure with technology that provides centralized,heterogeneous, and enterprise-wide network file management and control. • This technology includes a decoupling layer that separates logical file access from physical file locations and a variety of value-added file services.

21. A Simple FAN Model Information Producers and Consumers (Requesters) Global Namespace Consistent, Persistent, Reliable Namespace Wide-Area Storage Communication Optimization Optimize Remote Access and Replication Decoupling Heterogeneous “Virtual” NAS Mix and Match, Policy-Driven NAS Choice ofBest Storage Heterogeneous NAS Storage Building Blocks HighPerf NetApp Heterogeneous NAS Storage Building Blocks EMC Trad Tier-1 Trad Tier-2 IBM, HP Dell Windows High Security High Avail Linux Lowest Cost/GB …

22. IT Challenges / Business Needs Applications and Users • Files represent the largest portion of enterprise storage • Highest growth rate • Growing complexity • Mixed vendors, platforms, file systems • Increased application demands • Increased availability requirements • Enterprise-wide scope • This complexity is hampering the deployment of advanced file management services Static Mappings IP Network “Islands” of File Storage

23. Storage “Consumers” Logical Access “Decoupling” Services control Physical Access NAS Storage “Resources” FAN Targets These Challenges Applications and Users Storage • The Problem: • The tight bindings between applications and storage are preventing the evolution of storage management • The Solution: • A FAN “decouples” these relationships • This enables both basic and advanced storage management services

24. Decoupling Approaches • Client-based (out-of-band) • OS service or agent loaded on client system • Tree-level granularity with asynchronous updates • NAS-protocol specific • Hybrid (dual-band) • Combines client-based and network-based • Network-based (in-band) • Continuous network-resident decoupling • File-level granularity and synchronous updates • Support for all NAS protocols

25. Decoupling Approaches Client-based Hybrid Network-based Clients Tree-level Decoupling Tree Tree Tree File File File-level Decoupling Storage

26. “Basic” FAN Services • Migration • Move files from one server to another • Tiering / ILM • Place files via policy on the “best” storage • Load Balancing • Place files to better distribute capacity or load • Replication • Replicate files to support failover

27. Simplified Migration Flows Client-based Hybrid Network-based Clients Tree-level Decoupling Tree Map Tree Map Tree Map File Map File Map File-level Decoupling Storage

28. “On-Line” Service Capability

29. How a policy engine works Colleague saves data Policy engine Server name masked from the colleague Additional disk added quickly on demand Policies determine best location for data Policy moves unused data after 6 months Data moved to Tier 3 Tier 3 Tier 2

30. IT Challenges / Business Needs Applications and Users • Files represent the largest portion of enterprise storage • Highest growth rate • Growing complexity • Mixed vendors, platforms, file systems • Increased application demands • Increased availability requirements • Enterprise-wide scope • This complexity is hampering the deployment of advanced file management services Static Mappings IP Network “Islands” of File Storage
