Abstract

Official abstract text for this publication.

A method and system for manipulating a spin state of each disk in a drive array is disclosed. In one embodiment, a method includes monitoring input/output (I/O) requests to each disk drive in a disk array and identifying any disk drive as an inactive disk drive based on a number of I/O requests directed to said any disk drive for a given time interval. The method further includes moving data from the inactive disk drive to an active disk drive having a free disk space to store the data and updating metadata associated with the data using a log-structured file system for the disk array. Further, the method includes manipulating a spin state of the inactive disk drive by spinning down the inactive disk drive to conserve power. Furthermore, the method includes redirecting subsequent I/O requests for the inactive disk drive to the active disk drive by accessing the metadata of the log-structured file system.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for conserving power, the method comprising: monitoring first input/output (I/O) requests for a first disk drive; determining that the first disk drive is inactive based on a first number of first I/O requests directed to the first disk drive for a given time interval; monitoring second I/O requests for a second disk drive; determining that the second disk drive is active based on a second number of second I/O requests directed to the second d…
