Abstract

A storage server (110) for efficiently retrieving data from a plurality of disks (212) in response to user access requests. The server comprises a plurality of processors (302) coupled to disjoint subsets of disks, and a custom non-blocking packet switch (220) for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized.
By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users.
The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.
