Abstract
A configurable RAID subsystem includes a user data array connected to a user application via a block I/O path, and a configuration array connected to a configuration application via the same block I/O path. The user data array processes user data access commands executed by the user application; and the configuration application processes configuration commands, the user data access commands and the configuration commands communicated to the user data array and the configuration array respectively, via the block I/O path. A dynamic identification is assigned to the user data array by the configuration array, and a static identification is assigned to the configuration array.
