摘要
An I/O controller having separate command and data paths, thereby eliminating the bandwidth used by the commands and thus increasing bandwidth available to the data buses. Additionally, the I/O controller uses multiple dedicated data paths, for example, dedicated distributed buses, and provides increased speed due to improved hardware integration. The I/O controller employs distributed processing methods that decouple the external microprocessor from much of the decision-making, thereby providing improved operating efficiency and thus more useable bandwidth at any given clock frequency. Accordingly, the I/O controller is capable of maximizing I/O operations (IOPS) on all I/O ports by functioning at the rate of I/O connections to hosts and storage elements without becoming a bottleneck.
