SERVER RESOURCE ALLOCATION
First Claim
1. A method for processing transactions between a network file system (nfs) server and nfs clients, said method comprising:
- assigning a class designation to a workload request at an nfs client;
sending said workload request to said nfs server;
initiating an nfs workload handler and a resource table at said nfs server in response to receiving said workload request from said nfs client;
calculating a relative priority of said workload request from said nfs client among other existing workloads of other nfs clients to provide a prioritized listing of workload requests; and
allocating nfs resources by said nfs server based on a sum total of all current classes of workload requests at said nfs server.

Abstract
A method, programmed medium and system are disclosed which provide for end-to-end QoS for a set of processes that comprise a workload over nfs. A set of processes that comprise a workload such as the processes of a WPAR, or an entire LPAR are given a class designation and assigned priority/limits. The data are then passed to the server which allocates resources based on the sum total of all the current classes and their priorities and/or limits. This requires re-engineering the nfs client code to be workload-aware and the nfs server code to accommodate the resource allocation and prioritization needs of the nfs clients.

11. A computer program product for enabling processing of transactions between an nfs server and nfs clients, the computer program product comprising computer readable program code configured such that when such program code is read by said nfs server, said nfs server is operable for:
-
receiving a workload request from an nfs client, said workload request having been assigned a class designation by said nfs client; initiating an nfs workload handler and a resource table at said nfs server in response to receiving said workload request from said nfs client; calculating a relative priority of said workload request from said nfs client among other existing workloads of other nfs clients to provide a prioritized listing of workload requests; and allocating nfs resources by said nfs server based on a sum total of all current classes of workload requests at said nfs server. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A network file system (nfs) server configured for processing transactions with nfs clients, said nfs server comprising:
-
means for receiving a workload request from an nfs client, said workload request having been assigned a class designation by said nfs client; means for initiating an nfs workload handler and a resource table at said nfs server in response to receiving said workload request from said nfs client; means for calculating a relative priority of said workload request from said nfs client among other existing workloads of other nfs clients to provide a prioritized listing of workload requests; and means for allocating nfs resources by said nfs server based on a sum total of all current classes of workload requests at said nfs server. - View Dependent Claims (22, 23, 24)

25. A network file system (nfs) including an nfs server and a plurality of nfs clients connected in a network, said nfs server being configured for processing transactions with said nfs clients, said nfs system comprising:
-
a plurality of nfs clients; an nfs server coupled to said nfs clients; means at said nfs client for assigning a class designation, a priority designation and appropriate limits to a workload request of said nfs server; means for sending said workload request to said nfs server; server means for receiving a workload request from an nfs client, said workload request having been assigned a class designation, a priority designation and appropriate limits by said nfs client; server means for initiating an nfs workload handler and a resource table at said nfs server in response to receiving said workload request from said nfs client; server means for calculating a relative priority of said workload request from said nfs client among other existing workloads of other nfs clients to provide a prioritized listing of workload requests; and server means for allocating nfs resources by said nfs server based on a sum total of all current classes, priorities and limits of workload requests at said nfs server, said nfs system further including means for modifying processing at said nfs server to accommodate said nfs allocation of resources and means for making said nfs client aware of said allocating of nfs resources at said nfs server; means for adding said nfs allocation of resources to a resource table at said nfs server; and means for passing said prioritized listing of said nfs client workload requests down to underlying levels at said nfs server, said underlying levels including a task scheduler, file system and disk input-output (I/O) system at said nfs server, wherein said allocating is accomplished on a continuing basis upon receiving additional workload requests from one or more nfs clients, said nfs system further including deleting information associated with said nfs client from said resource table upon completion of said workload request from said nfs client.
