Abstract
For use with a computer system having an intelligent mass storage disk array subsystem, including a microprocessor controller, a method for the distribution of data within the disk array based upon logical commands issued by the computer system. The disk controller reads a logical command and translates the commands into multiple drive specific commands, including drive physical parameter information such as head, sector and cylinder selection. The calculation of these physical parameters is based upon a number of factors including the operating system installed in the computer system, the type of interleave scheme, if any, specified by the computer system configuration, and disk specific parameters. The physical drive requests are then placed in a queue and executed by the microprocessor controller. The method also encompasses a method for creating a disk array configuration to be loaded on all disks within the array based on existing valid disk array information and configuration information maintained by the computer system.
