1 Changing the economics of flash storage Delivering flash at the price of disk Mike Davis Director of Marketing SNIA DSI Co nference April 21, 2014

2 Flash economics are driving rapid adoption Pent- up demand for improving application performance at the right price point Multi- core processors drive up processor utilization and demand for more I/O per server, while HDD throughput remains flat Flash prices falling faster than HDDs but still considerably higher than 15K HDDs 15K HDD $/GB Flash SSD 7.2K HDD New form factors: PCIe cards, appliances, shared st orage Virtualization is increasing the demand for random I/ O with the mixer effect 1

4 Flash storage can be deployed at various layers to accelerate transactional application performance Dell Fluid Cache for DAS on Pow eredge Clie nt Network Indexing Maintains indexes to allow quicker access to data Runs on databases to accelerate locating a block of data in queries Data Warehousing Sto red data used to create reports or derive Business Intelligence Used for data mining, Server- based cache analysis, hypothesis testing, modeling Dell Compellent All-Flash or Hybrid- Flash Array Sto rage Network OLTP Manage transactionoriented applications, i.e. re tail, banking Business can be hurt if data not accessible,slow During peak usage, customer experience can be effected VDI Hosting desktop OS within a VM on a centralized server Tie ring or caching in shared storage Fac ilitate a quic k retrieval o f go ld im age s Boot storms, write allocations and latency are issues 3

6 What characterizes your workloads? Traditional one size fits all data storage strategy is unre alistic Performance expectations Access patterns and frequency Application performance semantics: Concurrent users, TPS Storage performance semantics: throughput, IOPS, performance per GB, File performance Ho t vs. cold data Read intensive vs write intensive Data o ptim ized fo r tie ring vs caching Random vs sequential Business value Data that is highly valuable to the business and can be used for deriving business intelligence, financial analysis, etc. Each type of data needs to be treated differently to align the application performance with capacity and cost requirements 5
