Abstract
Proposed are a storage apparatus and controlling method to prevent deterioration in the response performance of the whole system effectively. A storage apparatus provides a host computer with one or more storage areas for reading and writing data to the corresponding storage areas based on commands from the host computer. The number of receivable commands from the host computer is managed according to preconfigured management modes for managing the number of receivable commands. The management modes comprise at least one management mode among a first management mode for managing the number of receivable commands for each of the storage areas, a second management mode for managing the number of receivable commands in host group units which are sets of one or more of the host computers, and a third management mode for managing the number of receivable commands in identification information units assigned to the logged on host computers.
