Abstract
The present invention provides a storage subsystem accessing a storage resource efficiently to thereby enhance throughput. The storage subsystem adopts a configuration where respective processor packages have ownership of the respective LDEVs, wherein an I/O command from a host specifying an address extending over a division position within a single LDEV is divided, and the I/O processing is executed in a shared manner by multiple processor packages. The I/O processing is executed by allocating a processor package that processes a specific storage area with priority.
