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