Executive Summary

The storage industry is undergoing a major transformation as flash memory technology transitions from a tool for storing cell-phone address books into an enterprise-ready performance acceleration technology for large-scale disk-storage. This new technology opens a number of options for storage managers confronting a need for increased performance. Consider a storage system supporting a typical Online Transaction Processing (OLTP) workload. Such workloads are a mix of reads and writes, random and sequential accesses. Because rotating disk drives perform poorly under random access workloads, the throughput of OLTP systems often becomes limited by the performance of even the fastest disk drives.
