Data storage is just one element in the application delivery ecosystem, but it turns out that it is often the critical performance bottleneck. A number of new technologies have recently come to market that optimize storage performance. This session reviews several of these innovations and explains how performance-optimization technologies can be easily integrated into the existing storage infrastructure. Topics Include: * Understanding disk I/O patterns * SLC flash versus MLC flash versus DRAM * Packaging options for solid state storage * SQL database acceleration * MS Exchange acceleration * File system tiering acceleration * Dynamic tiered storage in a SAN array * Application-Level QoS * 3rd party caching appliances * Solid state storage and deduplication
