Storage performance in data warehouse environments often translates into I/O throughput (MB/s). For online transaction processing (OLTP) systems, the number of I/O requests per second (IOPS) is a key measure for performance.

Nondatabase files, including Oracle Database software, are not discussed because management of those files is no different from a non-VLDB environment. Therefore, the focus is on the high availability, performance, and manageability aspects of storage systems for VLDB environments.
