Abstract
A disk array controller apparatus (10) is disclosed having at least two logical ports (Logical Port #0-Logical Port #3) for interfacing with a host (12) and having one or more physical ports (Physical Port #0-Physical Port #4), each physical port arranged for attaching at least one disk drive to the controller, and the controller including a switch (26), the switch providing dynamically configurable data paths (30) between the logical data ports and physical data ports, responsive to the contents of a Mapping Register (24). The Mapping Register defines a desired disk drive array by specifying an association of each logical port to one of the physical ports. The mapping register can be organized as a logical mapping register, comprising a field for each logical port of the controller, and includes provision for designating a redundant array for RAID operations.
