Abstract: Various embodiments of systems and methods are disclosed for using priority information when handling error conditions for a storage resource. In some embodiments, a method involves detecting an error condition, which is associated with a storage resource, and selecting an error-correcting action in response to detection of the error condition. Selection of the error-correcting action is based on priority information. The priority information identifies respective priorities of several applications. At least one of the applications uses the storage resource when accessing application data.

Abstract: Disclosed is a method and apparatus for reading mirrored data. In one embodiment, a node receives a read request for data, identical copies of which are maintained on a primary storage device and any number of corresponding mirrors. A read generator coupled to the node generates a number of read operations for smaller portions of the data. Preferably, the read generator then transmits the read operations in parallel to at least two storage devices on which identical copies of the data are maintained (e.g., a primary storage device and a corresponding mirror, two mirrors of a primary storage device, etc.). The read operations may then be processed in parallel by the storage devices to which the read operations were transmitted.
