Monitoring transaction requests using a policy engine within a storage drive driver to change power capability and latency settings for a storage drive

摘要

With embodiments of the invention, a more robust solution is provided using a storage driver that may already be used for the platforms operating system. This is efficient because the storage driver typically already monitors storage drive access requests, and thus knows when traffic is outstanding (performance may be critical) or when it's not outstanding (and power may be saved).

主权项

1. A non-transitory memory storage device having instructions, that when executed in a computing platform, cause it to perform a method, comprising:
monitoring, by a policy engine within a storage drive driver associated with a storage drive, storage drive access request(s) to the storage drive to detect a first storage drive access request to the storage drive; queuing the first storage drive access request; determining whether the first storage drive access is a media access request; upon positive determination, undoing any pending power-down actions for the storage drive to bring the storage drive to a fully powered-on mode to complete the first storage drive access request; and upon negative determination, partially undoing any pending power-down actions for the storage drive to bring the storage drive to a partially powered-on mode to complete the first storage drive access request.
