2. State of the Market

3. Lots of Hype in the Marketplace

4. One Size does not fit all use cases GB/$ All HDD Arrays SATA Increasing Capacity C Hybrid Arrays Traditional RAID All Flash Arrays Performance IOPS/$ Increasing Performance

7. Seven Deadly Myths Myth #1: HDD-based arrays are history – the future is all-flash Level of belief: Low Reality: Myth – Users clearly favor a “right tool for the job” approach

8. Seven Deadly Myths Myth #2: All-flash is faster than hybrid storage • 76% believe all-flash is faster • Flash can lower latency for random reads • Sequential writes is another story • Must evaluate real-world workloads rather than marketing benchmarks Level of belief: High Reality: Myth - Different media types provide varying benefits

9. Seven Deadly Myths Myth #3: All-flash always runs cooler and requires less power than hybrid storage • 75% believe this perception • Flash modules/SSD’s draw less power as raw components • Storage arrays are not just raw storage • CPU’s, cache memory, etc are required Level of belief: High Reality: Myth – Real life customer tests have proven this

10. Seven Deadly Myths Myth #4: All-flash is more reliable than hybrid storage • 40% agree. Not majority, but significant • Due in large part to proliferation of SATA in enterprise arrays • Cell failure on NAND silicon results in shorter duty cycle • Proper vibration dampening and cooling, and self-healing technology can result in failure rates as low as 0.1% per annum Level of belief: Medium Reality: Myth – Hybrid arrays can deliver true “zero touch” duty cycles of over 7 years

11. Seven Deadly Myths Myth #5: All-flash costs the same as hybrid storage • 60% do not expect price parity for several years to come • High cost of all-flash cited as single biggest barrier to deployment • Dedupe and compression claim to lower amount of raw storage • Ironically, it’s usually low performance datasets that benefit most from dedupe/compression Level of belief: Low Reality: Myth – Customers should look at real-life workloads and 5 year TCO

12. Seven Deadly Myths Myth #6: Using consumer-grade flash is acceptable for most enterprises Level of belief: Low Reality: Myth – Customers clearly see the risk of such technologies

13. Seven Deadly Myths Myth #7: Most businesses need the performance all-flash offers • 90% believe no actual need for promised performance • Less than 10% of businesses peaked above 100,000 IOPS Level of belief: Low Reality: Myth – For most orginizations, all flash arrays are complete overkill for their requirements

15. Analysts finally taking note

16. Achieving the Best of Both Worlds Balancing Cost, Growth & Risk • Only real-time Hybrid Storage available • High Performance • Low Power • True Balance of Cost, Risk & Growth • Unique 5 year inclusive warranty Traditional Enterprise HDD Storage High Performance Flash Storage Real-Time Hybrid Storage Strengths Price Proven Technology Low Risk Weaknesses Latency Perceived Reliability Density / Scale Strengths I/O Performance Low Latency Low Power* Weaknesses Finite Lifetime Mixed workload ability Cost Flash Drives for… Low Latency Random Workloads Footprint Hard Drives for… Capacity Sequential Workloads Longevity Balanced Performance Cost Reliability

17. Performance where it’s needed Intelligent Storage Element Hyper ISE with CADP High Availability Accelerated Performance Consistent Performance Scale-Out Management Delivering Highest Performance in the Storage marketplace with HDDs Delivering SSD performance with low cost, TCO and operational simplicity Zero-Touch Reliability Risk Cost Growth

18. Proof from the field • The requirement • High Performance Storage for a bespoke app – large sequential write followed by random reads • The competition • Whiptail & Violin Memory • The challenge • Be “good enough” AND help the customer’s energy problems • The result • Performance the same • Power usage 50% lower than Violin • Five year CAPEX cost 33% of Violin price • Additional concerns around Violin roadmap and serviceability

19. The X-IO Effect Reduced virtualisation support calls by 80% with capex spend at less than 70% of incumbent storage vendor Large Housing Association UK Reduced SAP Transaction times by 90% with an investment of $100,000 Industrial Manufacturer Germany Reduced virtual desktop login times by over 90% Large Independent School District - US Reduced “close of business” time from 4 hours to 40 minutes and changed storage footprint by 93% Retail Banking ISV Increased I/O performance by 25x and improved VM deployment speed by 20x Cloud Services Provider UK

20. Storage is all about Balance Risk Cost Growth • Hard drives are far from dead • Capacity where it’s needed – Don’t focus too much on IOps • Flash is a tool, not a solution • Activity based tiering can be dangerous – Use real time IO analysis • The storage marketplace is changing • Storage should provide performance and reliability – not whistles and bells • Look at 5 year TCO, not just acquisition price • Also balance $/GB and $/IOP – Not mutually exclusive
