A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that 'virtualizes' a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

System and method for caching network file systems

An architecture, including a file-level protocol, for supporting sparse volumes on a storage system is provided. The file-level protocol provides coherency checking for use in retrieving data stored on a backing store remote from a storage system.

Architecture for supporting sparse volumes

A computer system having a memory for providing streaming media in one of a plurality of streaming media protocols includes a first plurality of interfaces configured to initiate reading of packet meta-data and packets of payload data from a memory, and a second plurality of interfaces configured to output streaming media packets to a client system at a requested pace, wherein the streaming media packets are determined in response to the packet meta-data, to the packets of payload data, and to a streaming media protocol requested, wherein the packet meta-data and the packets of payload data are read from the memory at a pace independent of the requested pace for the streaming media packets, and wherein the second plurality of interfaces support more than one streaming media protocol.

Methods and apparatus for pacing delivery of streaming media data

A cache memory configured to store media data to be output as a media stream includes a session data file configured to store properties of the media stream, wherein the properties may include encoding scheme, duration, and others, and a plurality of data object files, each data object file individually and directly accessible by a file system, each data object file comprising a data object configured to store only a portion of the media data.
