ABSTRACT:
A disk storage system has high throughput between a disk adapter of a disk controller and a disk array. The disk adapter of the disk controller is connected to the disk array through switches. Data on a channel between the switch and a RAID group is multiplexed in the switch to be transferred onto a channel between the switch and the disk adapter and data on the channel between the switch and the disk adapter is demultiplexed in the switch to be transferred onto the channel between the switch and the RAID group. A data transfer rate on the channel between the disk adapter and the switch is made higher than that on the channel.
