QUALITY OF SERVICE POLICY SETS

摘要

Disclosed are systems, computer-readable mediums, and methods for receiving client quality of service values associated with a first client. Client metrics of a volume in a storage system are determined for the first client. The client metrics reflect usage of the storage system by the first client. A client load value based is determined upon the client metrics. A quality of service management policy for the first client is determined from a plurality of quality of service management policies based upon the client load value. Each quality of service management policy comprises a formula based on a quality of service parameter. A client target performance value is determined based upon the formula of the quality of service management policy and the received client quality of service values. Performance of the storage system is adjusted for the first client based upon the client target performance value.

1. A method comprising:
receiving client quality of service values associated with a first client; determining client metrics of a volume in a storage system based upon use of the volume by the first client, wherein the storage system stores data from a plurality of clients, and wherein the client metrics reflect usage of the storage system by the first client; determining, using a processor, a client load value based upon the client metrics; determining a quality of service management policy for the first client from a plurality of quality of service management policies based upon the client load value, wherein each quality of service management policy comprises a formula, and wherein at least one formula includes a variable; calculating a client target performance value based upon the formula of the quality of service management policy that includes the variable, a value of the variable, and the received client quality of service values; adjusting performance of the storage system for the first client based upon the client target performance value; and adjusting performance of the storage system for a second client of the storage system based upon a second formula and different client target performance value associated with the second client.
