Abstract
Mechanisms and techniques allow a host computer system to control memory management techniques within a data storage system. The host computer system can detect a requirement of the computer system to access data in the data storage system and can identify a data access policy based on the requirement of the computer system to access data. The host can then include, within a data access request, a data access policy identifier that corresponds to the identified data access policy. The host then transmits the data access request including the data access policy identifier to the data storage system. The data storage system receives the data access request and selects a data access policy based on the data access policy identifier. The selected data access policy defining a memory management technique to use within the data storage system. The data storage system configures itself to operate according to the memory management technique and services the data access request according to the data access policy.
