Improve the maximum random access performance - I/O offloading

ETERNUS DX8700 S2 has I/O offloading for improving the maximum random access performance.
When I/O offloading is not set, two CPU cores in a controller process I/O and other two cores process RAID. When the I/O offloading is set, the two cores that processed RAID are to be offloaded and process I/O, a total of four cores can process I/O.
Distributed processing by four cores improves IOPS[1] performance and meets high requirement of random access.
