1 TAGITM Winter Summit 2017 Evaluating All Flash Storage for the Enterprise Presented by: John Barnard Field Solutions Manager, SHI Enterprise Solutions Group

2 Topics Four things you should know about flash memory The different classes of all-flash storage Evaluation criteria for all-flash storage

3 Four Things to Know About Flash Memory 1. Flash Can Wear Out P/E Cycles Over-Provisioning Write Optimization

4 Four Things to Know About Flash Memory 2. Flash Comes in Different Flavors SLC emlc cmlc TLC Flash Cell P/E Cycles 100,000 10,000 3, Performance Highest High High Medium Price per GB Highest High Moderate Low Bit Error Rate Low Low Low High

5 Four Things to Know About Flash Memory 3. Flash Fails Differently Than Spinning Disk HDD: Mechanical SSD: Bit Error Rate

6 Four Things to Know About Flash Memory 3. Flash Writes Are Expensive, Reads Are Free Asymmetric Read/Write Write Amplification Garbage Collection

7 Flash Architectures for Enterprise Storage Applications Server-Attached PCI Flash Array with Flash Cache Array with Flash Tier All-Flash Array PCIe card in application server Host CPU typically used for flash management 100s of GB Most Expensive cost-per- GB Flash as a read and/or write cache in array, or to cache file system metadata All data persisted to spinning disk Typically <1% - 5% of total capacity Sub-LUN/FS tiering, where a LUN or FS is spread across flash and disk Hot blocks/files moved to flash, cold left on disk Typically 1% - 10% of total capacity Not absolute fastest but delivers sub-millisecond IO Next-gen Tier 1 Infrastructure Efficient handling of mixed workloads Reduced physical and energy footprint

8 WHAT ALL-FLASH STORAGE CAN DO FOR YOU Greater Application Performance Responsiveness for a Digital Culture Operational Simplicity Accelerate NEXT-GEN initiatives Data Center Efficiency

9 EXPECTATIONS FOR FLASH Availability Resiliency Affordability Operational Simplicity

10 AVAILABILITY: IS THE ARCHITECTURE DESIGNED FOR NO DOWNTIME? Is the Controller Stateless? Is Performance Impacted During a Failure or Maintenance? Is Performance Impacted with Utilization at 100%? How Invisible is a Non-Disruptive Upgrade?

11 RESILIENCY: HOW IS THE DATA PROTECTED? How Many Drives Can Fail at Once? How Much Overhead is Required for Data Protection? Support for Snapshots and Replication?

12 AFFORDABILITY: DATA REDUCTION, SOFTWARE AND MAINTENANCE COSTS Data Compression Data Deduplication Global vs Optional Data Reduction Inline or Post-Process Data Deduplication? Are Data Services Software Included or Additional Cost? Do Maintenance and Support Cost Increase Over Time? What s the Infrastructure Tax When Scaling? What s the Density of the Infrastructure?

13 OPERATIONAL SIMPLICITY: HOW TO SCALE THE BUSINESS How Much Array Tuning is Required? How Much Application Tuning is Required? What Application Integration is Available? Does the Flash Provide a Programmable Set of APIs? What Management Tools are Available for Flash? What Support Model Does the Vendor Offer?

14 HOW MATURE IS THE FLASH PRODUCT? Benchmark and Certifications Are Analysts, Customers and Competitors Sharing Their Opinions? Industry Analysts Customer Experience Competitive Targeting
