4. Why Customers Choose XtremIO
Actual customer data | Workload: OLTP with 8KB Block Size
35TB Traditional Flash Array10TB XtremIO ‘X-Brick’
IOPS
Traditional Flash Array
= 4x more expensive
• 70K IOPS for 35TB Traditional
Flash Array
• 70K IOPS for 10TB XtremIO All-
Flash Array
Latency
Latency Spikes • 2-4.5ms = Traditional Flash
• Various latency spikes
• <1ms = XtremIO
• Consistent & Predictable (~0.5ms)
Latency
• 20-40ms = Traditional Flash
• Latency increases with capacity
• <1ms = XtremIO
• Always Consistent & Predictable
System-Level Garbage Collection Impact
Worse than
Disk Latency

5. Workload Distribution (Based on $)
Note:
(1) Algorithm based on taking into consideration all workloads in multi-workload scenarios and finding % share in total # of observations.
(2) Data pulled on 1.1.2015.
• In Q1’14, VDI was the primary WL with 42% share
• In Q4’14, DBs was the primary WL with 54% share
• VSI share has increased every quarter from 8% to 30%

6. Why did Flash need a new Architecture?
• SSD has it’s own unique strengths
• SSD also has some unique weaknesses
• What’s good for Traditional Disk can be BAD for SSD

• Clustered N-Way Active Controllers
• RDMA Infiniband Backplane
• Scale-Out up to 6 X-Bricks
• Scales from 5TB to 120TB RAW

9. Optimized for SSD – No Overwrites
SSD writes are penalized!
• SSD’s have limited life
• Cell erasure
• Write Amplification
Optimized for partial stripe writes
Leverages random access
Drive based garbage collection – No System IO cost
