7 INDUSTRY TRENDS: BUILDING BLOCKS FOR NEXT GENERATION DATACENTER Next Generation Applications Trend PaaS, Mobile, Hadoop Which Will Enable Hybrid Clouds Which Will Be Used As Building Blocks Which Will Be Deployed In CI Hybrid Cloud Trend Software-Defined Data Center Trend Converged Infrastructure Trend Elastic, Agile, Data Center Running Next Generation Apps 2 Key Changes To The Underlying Storage Market Flash Trend New Levels of Performance COTS Trend New Levels of Efficiency 7

8 All-Flash Arrays (AFA) 8

9 Evolution of All-Flash Array Architectures This research shows that flash will become the lowest cost media for almost all storage from 2016 and beyond, and that a shared data philosophy is required to maximize the potential from both storage cost and application functionality perspectives. 9

10 Why Flash? Challenge #1: Latency Bad user experience Application timeout Lost time = money 10

11 Why Flash? Latency cause: CPU HDD performance gap CPU IS FAST AND GETS FASTER DISK IS SLOW AND DOES NOT GET ANY FASTER LATENCY x 800x 10000x 11

12 Why Flash? Solution: Flash will close the performance gap CPU IS FAST AND GETS FASTER FLASH IS FAST AND GETS FASTER x 800x 10000x 12

13 XtremIO Sudden Impact - SQL Server 13

14 Business Value of next generation All-Flash-Array: lu re business will run faster Faster Applications -> Happier users More Transactions -> More sales Faster reports -> Instant business decisions Able to trade for 40 minutes extra per day = 156,000 per day 14

15 Gen 1 Flash Systems Legacy Disk Arrays The Evolution of FLASH Arrays Flash Optimized Hybrids Dual Controller Limited Scale Single Workloads Some Data Services Scale Up All Flash Arrays Dual Controller Limited Scale Single Workloads Sometimes Data Services Compromise Between Performance & Efficiency - Data Svcs Scale Out All Flash Arrays Multi Controller (16-XtremIO) Petabyte Scale Mixed Workloads In-Line Data Services Lowest TCO Highest Performance All Flash Data Center Gen 1 Gen 2 Gen 3 Gen 4 Source: Wikibon December

16 Avoiding Bad Design Choices 5 Common Things AFAs Borrow from Disk Log Structuring Uneven SSD wear Post-Process Performance inconsistency RAID Par ity Par ity Par ity Par ity SSD Wear - Write Amplification Metadata De-stage Performance inconsistency Asymmetric Controllers A P Uneven Resource Utilization XTREMIO DOES NOT USE ANY OF THESE 16

17 XTREMIO DATA PROTECTION Designed for SSD No legacy RAID baggage Highly efficient- only 8% overhead Lowest write amplification SSDs may fail in place No configuration No hot spares Adapts to failures High Performance RAID 1 Good Capacity Utilization RAID 5 XDP Superior Protection RAID 6 Copyright 2014 EMC Corporation.

18 Typical AFA System Level Garbage Collection Array Controller Huge back-end I/O amplification initiated by array controller Cannot defer process when array must free up space Big tax on array controllers to manage limits capacity 18

19 XtremIO No System Level Tax XtremIO Controller No Garbage Collection ASIC ASIC ASIC ASIC ASIC ASIC ASIC ASIC ASIC Performed by Each SSD Controller ASIC SSD controllers have ideal knowledge of the NAND Zero back-end I/O initiated by the array controllers No tax on array controllers 19

20 Why Customers Choose XtremIO Latency Latency Consistent High Performance & Low Latency Actual customer data Workload: OLTP with 8KB Block Size Latency Spikes 2-4.5ms = Gen 3 Flash Various latency spikes <1ms = XtremIO Consistent & Predictable (~0.5ms) System-Level Garbage Collection Impact Worse than Disk Latency 20-40ms = Gen 3 Flash Latency increases with capacity <1ms = XtremIO Always Consistent & Predictable XtremIO X-Brick Traditional Flash Array 20
