Abstract
A SATA-compatible storage controller that can be configured to allow computers assigned to multiple different computer domains connected by at least one switch fabric to share resources of a common set of storage devices. The storage controller includes a plurality of virtual storage controllers, each providing an interface to a respective computer domain connected to the switch fabric, a virtualization mechanism configured to implement link layer virtualization for the common set of storage devices, and a split serial advanced technology attachment (SATA) protocol stack, the processing of which is partitioned between the respective virtual storage controllers and the virtualization mechanism.
