1. A method, comprising:
- receiving, in a storage system, an input/output request directed from a database to a storage system;
determining from the input/out request that the database corresponds to a particular one of a plurality of database classes;
classifying, in the storage system, the input/output request under at least the particular database class, wherein a database classifier is included with the input/output request to identify the particular database class;
associating, in the storage system and prior to receipt of the input/output request, a particular quality of service policy with the particular database class; and
executing the input/output request in the storage system according to the particular quality of service policy.

Abstract
In accordance with some embodiments, classification of input/output requests from a database to a storage system may be performed. Each input/output request may be associated with a database class, and each database class may be mapped to a quality of service policy. Thus, quality of service may be enforced such that different data blocks within the storage system of the database may be afforded appropriate quality of service.
