Abstract
A data storage system has at least three data storage disks and a plurality of processing nodes in communication with the data storage disks. Each of the processing nodes shares access to the data storage disks, and each of the processing nodes includes a distributed lock manager that allows or denies access to selected stripes of data storage sectors on any of the data storage disks. Each of the processing nodes includes an interface to a private communication link to a single one of a plurality of host operating systems.
