X-IO Technologies All Flash Arrays – Saviour of the storage world ? October 2013 Jim Litke Principal Systems Engineer X-IO

X-IO Technologies – Confidential State of the Market

X-IO Technologies – Confidential Lots of Hype in the Marketplace

X-IO Technologies – Confidential 4 One Size does not fit all use cases Increasing Performance SATA Hybrid Arrays Traditional RAID All Flash Arrays Increasing Capacity GB/$ IOPS/$ Performance C All HDD Arrays

X-IO Technologies – Confidential How clear are you about the benefits offered by flash-only arrays vs. traditional HDD arrays? Market Clarity Source: Vanson Bourne Market Survey for X-IO, 2013

X-IO Technologies – Confidential 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

X-IO Technologies – Confidential Seven Deadly Myths Myth #2: All-flash is faster than hybrid storage Level of belief: High Reality: Myth - Different media types provide varying benefits 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

X-IO Technologies – Confidential Seven Deadly Myths Myth #3: All-flash always runs cooler and requires less power than hybrid storage Level of belief: High Reality: Myth – Real life customer tests have proven this 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

X-IO Technologies – Confidential Seven Deadly Myths Myth #4: All-flash is more reliable than hybrid storage Level of belief: Medium Reality: Myth – Hybrid arrays can deliver true “zero touch” duty cycles of over 7 years 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

X-IO Technologies – Confidential Seven Deadly Myths Myth #5: All-flash costs the same as hybrid storage Level of belief: Low Reality: Myth – Customers should look at real-life workloads and 5 year TCO 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

X-IO Technologies – Confidential 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

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

X-IO Technologies – Confidential 15 Analysts finally taking note

X-IO Technologies – Confidential Achieving the Best of Both Worlds Traditional Enterprise HDD Storage High Performance Flash 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 Balanced Performance Cost Reliability Hard Drives for… Capacity Sequential Workloads Longevity Flash Drives for… Low Latency Random Workloads Footprint Real-Time Hybrid Storage Only real- time Hybrid Storage available High Performance Low Power True Balance of Cost, Risk & Growth Unique 5 year inclusive warranty Balancing Cost, Growth & Risk

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

X-IO Technologies – Confidential 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 Proof from the field

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

X-IO Technologies – Confidential Storage is all about Balance 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
