Abstract
A method for enforcing a service discrimination policy in a storage system. The service discrimination policy enforcement method can include monitoring load metrics for physical resources required to access content stored within the storage system. A request to access the content stored within the storage system can be received. A corresponding guaranteed service level can be identified from the request. In consequence, a particular one of the physical resources can be selected to service the request based upon a determination that the selected physical resource can service the request while satisfying the guaranteed service level at a load indicated by the monitored load metrics.
Claims15
A storage system comprising:
- storage media comprising physical resources for accessing content stored in said storage media;
- a storage system controller coupled to said physical resources, said storage system controller provisioning individual ones of said physical resources to respond to requests to access said content;
- a resource monitor configured to monitor load metrics for said physical resources;
- and,
- a service level policy enforcement processor programmed to access service level terms and, based upon said service level terms and said load metrics, to selectively provision individual ones of said physical resources to respond to requests to access the content stored in said storage media.
In a storage system, a service discrimination policy enforcement method comprising the steps of:
- monitoring load metrics for physical resources required to access content stored within the storage system;
- receiving a request to access said content stored within the storage system;
- identifying from said access request a corresponding guaranteed service level;
- and,
- selecting a particular one of said physical resources to service said request based upon a determination that said selected particular one of said physical resources can service said request while satisfying said guaranteed service level at a load indicated by said monitored load metrics.
In a storage system, a machine readable storage having stored thereon a computer program for enforcing a service discrimination policy, said computer program comprising a routine set of instructions for causing the machine to perform the steps of:
- monitoring load metrics for physical resources required to access content stored within the storage system;
- receiving a request to access said content stored within the storage system;
- identifying from said access request a corresponding guaranteed service level;
- and,
- selecting a particular one of said physical resources to service said request based upon a determination that said selected particular one of said physical resources can service said request while satisfying said guaranteed service level at a load indicated by said monitored load metrics.
