Abstract
Whenever a controller receives a message that includes a particular target ID and a particular computer's operating requirements with respect to the operation of the plurality of logical units mapped across a plurality of disk storage devices, the controller stores one set of the particular computer's operating requirements per target ID per logical unit. Each host computer in a data storage system that has substantially similar operating requirements uses the same target ID in any I/O requests to a controller. Subsequently, whenever the controller processes an I/O request from any computer that uses the particular target ID, the controller will use the particular set of the operating requirements to configure the operation of each of the logical units.
