The dual disk channel design supports up to 14 disk drives. This allows for the creation of high capacity disk arrays. Each pair of disks that are connected logically form a single disk to the host system. Multiple disks or sets of disks can be joined as a group to form a larger disk. As an example, if four (4) sets of disks are connected with each set having a 4GB capacity, the user can select to concatenate (span) the sets which form a single disk drive. Therefore, the host will identify a single disk drive having an overall capacity of 4GB x 4 or 16GB.
