Abstract
An invention is provided for highly scalable data storage. The invention includes a logical storage device having a logical device queue, where the logical device queue includes a plurality of command slots for storing input/output commands. Also included is a plurality of I/O worker processes, each associated with a command slot of the logical device queue, and a logical device queue process which is associated with the logical storage device. When a command is placed in the logical device queue, the logical device queue process provides an index for the command to an I/O worker process associated with the command slot storing the command. The I/O worker process then obtains the command from the logical device queue and facilitates completion of the command.
