Storage subsystem device driver scheduling I/O servicing according to priority of identified process

摘要

Systems, methods, and apparatus to identify and prioritize application processes in one or more subsystems. Some embodiments identifying applications and processes associated with each application executing on a system, apply one or more priority rules to the identified applications and processes to generate priority information, and transmit the priority information to a subsystem. The subsystem then matches received requests with the priority information and services the processes according to the priority information.

1. A method comprising:
identifying applications and processes associated with each identified application executing on a system by calling an operating system routine; applying one or more priority rules to the identified applications and processes to generate priority information, at least one of the one or more priority rules including an administrator defined priority rule; transmitting the priority information to a storage subsystem device driver; and executing the storage subsystem device driver to:
store, on the storage subsystem, the priority information in a table;match storage subsystem processes with a priority in the table, the storage subsystem processes being processes of the identified processes; andschedule storage subsystem process servicing according to the matching.
