Enhancing file system performance
First Claim
1. A file system that balances the loading of servers and the capacity of drives associated with the servers, the file system comprising:
- a first disk drive including a first unused capacity;
a second disk drive including a second unused capacity, wherein the second unused capacity is smaller than the first unused capacity;
a first server configured to fill requests from clients through access to at least the first disk drive; and
a second server configured to fill requests from clients through access to at least the second disk drive, and configured to select an infrequently accessed file from the second disk drive and push said infrequently accessed files to the first disk drive, thereby improving a balance of unused capacity between the first and second disk drives without substantially affecting a loading for each of the first and second servers.

Abstract
A file system that balances the loading of filers and the capacity of drives that are associated with the filers is described. The file system includes a first disk drive that includes a first unused capacity and a second disk drive that includes a second unused capacity, wherein the second unused capacity is smaller than the first unused capacity. The file system further includes a first filer that is configured to fill requests from clients through access to at least the first disk drive. The file system further includes a second filer that is configured to fill requests from clients through access to at least the second disk drive. The second filer is configured to select an infrequently accessed file from the second disk drive and to push the infrequently accessed files to the first disk drive, thereby improving a balance of unused capacity between the first and second disk drives without substantially affecting a loading for each of the first and second filers.

4. A file system to balance the loading of servers and the capacity of drives associated with the servers, the file system comprising:
-
a first disk drive;
a second disk drive including a heavily accessed file;
a first server configured to fill requests from clients through access to at least the first disk drive; and
a second server configured to fill requests from clients through access to at least the second disk drive, and configured to push a copy of the heavily accessed file to the first disk drive and to return file handles to the clients, wherein at least some of the file handles designate the second server, thereby improving a balance of loading on each of the first and second servers.

5. A distributed file system to balance the loading of servers and the capacity of drives using server-independent object positioning, the file system comprising:
-
a first server including;
a first server profile comprising information about the first server, and a first object positioner; and
a second server including;
a second server profile comprising information about the second server, and a second object positioner configured to accept the first server profile and the second server profile and to generate a second object positioning plan, wherein the first object positioner is configured to accept the first server profile and the second server profile and to generate a first object positioning plan. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
