Abstract
An array of disk drives stores information which is accessed through multiple channels by a host computer. Different channels are coupled to different sequences of disk drives. Different disk drives can be accessed simultaneously through different channels, enabling high data transfer rates. The same disk drive can be accessed through two different channels, enabling access even if one off the channels is busy or malfunctioning. According to one aspect of the invention the channels are divided into at least two mutually exclusive sets of channels, each set providing access to all the disk drives.
