4. Industry Trends – Information Security Is more data being lost or stolen today than in the past? Lost tapes are actually on the decline, however… Encryption Data At Rest and In-Flight, FDE and Drive Trust, Host Software and Storage Encrypt, Key Management, Secure Digital Destruction Authorization, Authentication, Identity Management Lost tapes make good news copy, however, lost or stolen PDAs, USB devices, laptops and HDDs removed from retired storage systems are a growing threat risk. Reported along with unreported events are on the rise! Growing Awareness! Lost Data Events A key question is, can you or your business afford the risk of data being lost or stolen? Time

5. Industry Trends – Compute Continuum We are in a consolidation phase (again!) Cell Phones, PDAs, Pocket PCs Desktop PCs & Laptops Midrange & Servers Mainframes Converged Phones & Computers From Desktop to Laptop x86 and VMs From Proprietary to x86 & Hypervisors & Open LPARs/VMs Open Networking Native Linux Distribute Distribute Distribute Consolidate Consolidate 1950s 1960s 1970s 1980s 1990s 2000s 2010s SaaS Software or Storage as a Service Service Bureau Info Utilities Managed Service Providers Grid, Cloud, Web 2.0 Outsource & In-source xSPs Client Server

6. Industry Trends – Increased Density Rising demand, denser solutions, PCFE and complexity • More processing power per footprint (sq. foot or meter, cabinet U) • Performance density improvements and cost reductions continue • Same floor space occupied to host more compute capabilities • More processing cycles will be needed moving forward • More processing cycles per watt of energy consumed • Power, cooling, floor space and EHS improvements 128 Servers (Blade Centers) Single Large Server Same Footprint Different Generations over Time 24 Servers Eight Servers Four Servers Source: “The Green and Virtual Data Center” (Auerbach)

7. Web 2.0 and Online Data Data Created Continued Access Activity 8 Time Profile: Data is created, worked with and then may go idle briefly, then accessed, then idle, then active, then idle, then active… Examples: Web, reference and lookup, fixed content, Web 2.0 and social networking, media and entertainment, some email, search, seasonal or event and research-based data Solution: Online storage with variable performance to meet changing workload demands, bulk and clustered storage, MAID 2.0 and IPM-enabled storage, caching Industry Trends – Shifting Landscapes Common challenges and issues – old vs. new rules! Legacy and Transactional Data Data Created Data Goes Dormant Activity 8 Time Profile: Data is created, worked with and then goes dormant after some period of time with probability of little to no future access or use Examples: Database, email, transactional, general file serving, project-oriented data Solution: Ideal candidate for archiving off of primary or online storage to off-line and removable media or MAID-based storage combined with purging or deletion of data no longer needed to meet compliance or other commitments Source: “The Green and Virtual Data Center” (Auerbach)
