Embodiments of methods to communicate a timestamp to a storage system are generally described herein. Other embodiments may be described and claimed.

Methods to communicate a timestamp to a storage system

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.

Selective I/O prioritization by system process/thread

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

Methods and apparatuses for identifying types of data streams and communicating stream information to improve performance of data storage devices are disclosed. Method embodiments generally comprise identifying one or more isochronous requests among a plurality of requests which may be issued to a data storage device, assigning a completion deadline an isochronous request, and communicating the isochronous request and completion deadline information to the data storage device. Apparatus embodiments generally comprise a request identifier to identify an isochronous request, a logic module to assign a completion deadline to the isochronous request, and a communication module to communicate the isochronous request and the completion deadline to a data storage device. Alternative apparatus embodiments may include a monitor module to monitor a system process operating in the system and determine if the system process issues isochronous requests. Various embodiments may process asynchronous requests, including prioritized asynchronous requests, with the isochronous requests.
