Selective i/o prioritization by system process/thread

Abstract

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.

What is claimed is: 
     
         1 . A method comprising:
 identifying applications and processes associated with each 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; and   transmitting the priority information to a storage subsystem.
