Quality of service policy sets

A non-transitory computer-readable medium having instructions stored thereon, that when executed by a computing device cause the computing device to perform operations 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 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 based on a quality of service parameter;
• calculating a client target performance value based upon the formula of the quality of service management policy 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, wherein performance of the storage system is adjusted for a second client of the storage system based upon a different client target performance value associated with the second client;
• receiving a schedule of quality of service values associated with the first client that includes quality of service values, wherein each quality of service value is associated with a date or a time of day;
• determining the client quality of service values to use in calculating the client target performance value based upon the schedule of quality of service values;
• wherein receiving the schedule of quality of service values includes receiving a request to increase a maximum quality of service value for a time period;
• setting the maximum quality of service parameter for the first client to an increased maximum quality of service value for the time period;
• and
• resetting the maximum quality of service parameter to the maximum quality of service value after expiration of the time period.

A system comprising:

• one or more processors configured to:
• receive client quality of service values associated with a first client;
• determine 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;
• determine a client load value based upon the client metrics;
• determine 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 based on a quality of service parameter;
• calculate a client target performance value based upon the formula of the quality of service management policy and the received client quality of service values;
• and
• adjust performance of the storage system for the first client based upon the client target performance value, wherein performance of the storage system is adjusted for a second client of the storage system based upon a different client target performance value associated with the second client;
• receive a schedule of quality of service values associated with the first client that includes quality of service values, wherein each quality of service value is associated with a date or a time of day;
• determine the client quality of service values to use in calculating the client target performance value based upon the schedule of quality of service values;
• receive a request to increase a maximum quality of service value for a time period;
• set the maximum quality of service parameter for the first client to an increased maximum quality of service value for the time period;
• and
• reset the maximum quality of service parameter to the maximum quality of service value after expiration of the time period.
