2. 2 Solutions Road Show 2014 March 2014 | India Data that is highly valuable to the business and can be used for deriving business intelligence, financial analysis, etc. Read and write percentages Transfer sizes Sustained vs. bursty I/O patterns Data accessed frequently vs. cold, rarely accessed data Heavily read vs heavily written data Data optimized for tiering vs caching Performance Access patterns and frequency I/O patterns Business value Hot data that needs to be retrieved extremely fast without latency IOPS vs. throughput What characterizes your workloads? Traditional “one size fits all” data storage strategy is inefficient Each type of data needs to be treated differently to align the application performance with capacity and cost requirements

3. 3 Solutions Road Show 2014 March 2014 | India New form factors: PCIe cards, appliances, shared storage Virtualization is increasing the demand for random I/O with the “mixer effect” Flash prices falling faster than HDDs but still considerably higher than 15K HDDs Multi-core processors drive up processor utilization and demand for more I/O per server Flash adoption is accelerating Pent-up demand for improving application performance at the right price point 15K HDD $/GB Flash SSD 7.2K HDD

4. 4 Solutions Road Show 2014 March 2014 | India Flash storage can be deployed at various layers to accelerate application performance Server-based cache (Tier-0) Flash drives placed directly on high speed PCI bus in application servers Caching software enables server to leverage flash storage as an extension of memory cache SSD tiering in shared storage A few SSDs can be added to the array to dramatically increase performance for targeted workloads OR An entire storage tier can be deployed on SSDs so that complete volumes and datasets can be fit in flash COMING SOON: Fluid Cache for SAN Benefits of Fluid Cache extended to the entire SAN for maximum performance and reliability Storage Network Client Network Dell Fluid Cache for DAS on PowerEdge Dell Compellent All-Flash or Hybrid-Flash Array
