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.

Claims

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.

2. The method as set forth in claim 1 wherein said nfs server processing is modified to accommodate said nfs allocation of resources and said nfs client is made aware of said allocating of nfs resources at said nfs server.

3. The method as set forth in claim 2 and further including adding said nfs allocation of resources to a resource table at said nfs server.

4. The method as set forth in claim 3 and further including passing said prioritized listing of said nfs client workload requests down to underlying levels at said nfs server.

5. The method as set forth in claim 4 and further including passing said prioritized listing of said nfs client workload requests down to a task scheduler, file system and disk input-output (I/O) system at said nfs server.

6. The method as set forth in claim 5 wherein said allocating is accomplished on a continuing basis upon receiving additional workload requests from one or more nfs clients.

7. The method as set forth in claim 6 and further including deleting information associated with said nfs client from said resource table upon completion of said workload request from said nfs client.

8. The method as set forth in claim 1 and further including assigning priorities to said workload requests from said nfs client.

9. The method as set forth in claim 8 and further including assigning limits to said workload requests from said nfs client.

10. The method as set forth in claim 9 wherein said nfs resources are allocated by said nfs server based on all current classes, priorities and limits of workload requests received at said nfs server.
