    摘要： A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch 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.

    摘要： A method of data management for efficiently storing and retrieving data in response to user access requests. The architecture comprises a plurality of disk drives over which data is distributed, and a plurality of processors, each of which is assigned to a subset of the disk drives in a modular fashion. The server architecture employs dynamic data management methods and load-balancing methods to assign user requests to processors. The modular server architecture, in combination with the dynamic data management and load balancing methods, provides both good performance (i.e., low expected-case access times and high disk bandwidth), and fault-tolerance. 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 programs.

    摘要： A queuing architecture and method for scheduling disk drive access requests in a video server. The queuing architecture employs a controlled admission policy that determines how a new user is assigned to a specific disk drive in a disk drive array. The queuing architecture includes, for each disk drive, a first queue for requests from users currently receiving information from the server, and a second queue for all other disk access requests, as well as a queue selector selecting a particular first queue or second queue for enqueuing a request based on the controlled admission policy. The controlled admission policy defines a critical time period such that if a new user request can be fulfilled without causing a steady-state access request for a particular disk drive to miss a time deadline, the new user request is enqueued in the second queue of the particular disk drive; otherwise, the controlled admission policy enqueues the new user request in a second queue of another disk drive.
