Storage subsystem and its control method |
摘要 |
Provided is a storage subsystem capable of maintaining the reliability of I/O processing to a host apparatus, even if there is an unauthorized access from a processor core to a switch circuit, by applying a multi-core system to a processor. A multi-core processor is applied to a second logical address space that is different from a first logical address space to be commonly applied to multiple controlled units such as a host interface to be accessed by the processor. The switch circuit determines the processor core that issued an access based on an address belonging to a second address space, and maps an address containing in an access from the processor core to an address of a first address space.
