Power management in a storage array
First Claim
1. A data storage system comprising:
- an enclosure supporting a self-contained plurality of discrete data storage devices configured for connecting with a network device via a network;
a redundant array of independent drives (RAID) container services module in the enclosure that allocates and manages a storage space of the data storage devices for storing primary and redundant data; and
a policy engine in the enclosure that continuously and qualitatively characterizes the network load to the data storage system and manages a power distribution to each of the data storage devices based on a predicted utilization that differentiates between access commands for primary data and access commands for redundant data.

Abstract
A data storage system and associated method is provided within an enclosure supporting a self-contained plurality of discrete data storage devices configured for connecting with a network device via a network. The data storage system includes a redundant array of independent drives (RAID) container services module in the enclosure that allocates and manages a storage space of the data storage devices for storing primary and redundant data, and a policy engine in the enclosure that continuously and qualitatively characterizes the network load to the data storage system and manages a power distribution to each of the data storage devices based on a predicted utilization that differentiates between access commands for primary data and access commands for redundant data.

9. A method for managing power in a pool of data storage devices, comprising:
-
placing the pool of data storage devices in a common enclosure with a policy engine in the enclosure capable of characterizing network access commands; monitoring time of day information for access commands to each data storage device differentiated between access commands for RAID primary data as opposed to access commands for RAID redundant data; calculating a statistical record of the actual utilization of each data storage device in the pool from the monitoring step findings; predicting future utilizations of each data storage device from results of the calculating step. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
