A network storage controller for transferring data between a host computer and a storage device, such as a redundant array of inexpensive disks RAID, is disclosed. The network storage controller includes at least one channel interface module which is connected to a passive backplane, and selectively transfers data between the host computer and storage device and the passive backplane. The network storage controller also includes at least one controller memory module 104, 108, which communicates with the channel interface module 136, 140 via passive backplane 116, and processes and temporarily stores data received from the host computer or storage device. In applications where redundancy is required, at least two controller memory modules and two channel interface modules are used. The controller memory modules may mirror data between one another using the passive backplane and a shared communication path on the channel interface modules, thereby substantially avoiding the use of host or disk channels to mirror data.
