| Abstract: |
A resource allocation manager and technique for servers within a computer system. Resources are initially allocated to servers and in order to enhance system performance, resources are reallocated based on a minimization of the maximum performance index. In one example, the server with the largest performance index is allocated additional resources and the server with the smallest performance index loses some of its resources.

What is claimed is:
1. A method for managing allocation of resources in a computer system having a plurality of servers, each of said servers having a size value associated therewith, said method comprising:
- (a) calculating a first performance index for each of said plurality of servers using its size value minus a predefined number of resources to be exchanged, such that a plurality of first performance indexes is provided;
- (b) determining a minimum server by selecting from said plurality of first performance indexes a minimum performance index;
- (c) calculating a second performance index for each of said plurality of servers using its size value plus said predefined number of resources to be exchanged, such that a plurality of second performance indexes is provided;
- (d) determining a maximum server by selecting from said plurality of second performance indexes a maximum performance index;
- (e) calculating a third performance index for said minimum server using its size value;
- (f) calculating a fourth performance index for said maximum server using its size value;
- (g) increasing the size value of the maximum server when a maximum value of said third and fourth performance indexes is greater than a maximum value of said minimum performance index and said maximum performance index;
- (h) decreasing the size value of the minimum server when a maximum value of said third and fourth performance indexes is greater than a maximum value of said minimum performance index and said maximum performance index;
- (i) repeating calculating step (a), determining step (b), calculating step (c), determining step (d), calculating steps (e) and (f), increasing step (g) and decreasing step (h) until a maximum value of said third and fourth performance indexes is not greater than a maximum value of said minimum performance index and said maximum performance index;
- (j) removing resources from each of said plurality of servers having a decreased size value; and
- (k) adding resources to each of said plurality of servers having an increased size value.
