Chief Judge Gregory M.

-“identifier of the segment”
-“identifier of a segment”
-“identifier of the requested segment”
-“means, operative in response to a request from one of the client systems, for retrieving the requested segment of the file from the storage unit using the information associating the identifier of each segment stored on the storage unit with the location of each segment of the storage unit”
-“means for sending the requested segment to the client system”
-“means for sending a request, for each segment of the data requested by the application, to the storage unit on which the segment is stored”
-“means for selecting one of the storage units on which the segment is stored such that a load of requests on the plurality of storage units is substantially balanced”
-“means for scheduling the transfer of data from the storage unit such that the storage unit efficiently transfers data” and
-“means for distributing each segment, and the redundancy information for each segment, among the plurality of storage units by sending to the storage unit the segment of the data and the identifier of the segment”.
