Proportional quality of service based on client usage and system metrics
First Claim
1. A method comprising:
- determining a system load value of a distributed storage system based upon a plurality of service load values calculated for services on nodes of the distributed storage system;
determining the system load value is above a predefined threshold;
calculating proportional contribution to the system load value for each of a plurality of clients based on the plurality of service load values calculated for the services;
identifying at least a first client of the plurality of clients for performance throttling based on the calculated proportional contributions;
calculating a target performance value for the first client, wherein calculation of the target performance value is based upon the calculated proportional contribution of the first client to the system load value and quality of service parameter values for the first client; and
throttling performance of the distributed storage system for the first client based upon the target performance value.

Abstract
Disclosed are systems, computer-readable mediums, and methods for determining client metrics of a volume in a storage system for a first client of a plurality of clients. The storage system stores data from the plurality of clients. System metrics of a cluster in the storage system are determined based upon use of the storage system by the plurality of clients. A load value of the storage system is determined based upon the system metrics and the client metrics. The load value is determined to be above a predefined threshold. A target performance value is calculated based upon the load value, a minimum quality of service value, and a maximum quality of service value. Performance of the storage system is adjusted for the client based upon the target performance value and the determining the load value is above the predefined threshold.
