Abstract

See full text

A host performs benchmark I/O operations for a storage system by an application on the host formulating a performance test command, providing the performance test command to a channel subsystem layer of the host that actuates communication hardware that provides signals to the storage system, and performing a plurality of benchmark I/O operations at the channel subsystem layer in response to a single performance test command by actuating the communication hardware that provides signals to the storage system. The single performance test command may result in actuating the communication hardware to read and write data at a plurality of addresses of the storage system. The channel subsystem layer may perform the plurality of benchmark I/O operations without receiving any additional data or commands from any applications on the host. A dispatch program that runs on the channel subsystem layer may receive operational data and may actuate the communication hardware.
