MAID for Green: Energy Conservation with
Fujitsu ETERNUS Storage Systems
A Fujitsu White Paper
http://www.fujitsu.com/us/
Abstract
Today, because of strong demand for storage capacity, customers are faced with serious issues of power and cooling in their data centers. The density of today's storage systems, the insatiable demand for storage and the rising cost of energy are forerunners of an impending energy crisis in the data center
Fujitsu's ETERNUS storage systems deliver features designed to address the power and ecological demands of our customers. Using the virtualization features of ETERNUS storage systems, such as RAID migration, RAID expansion and LUN concatenation, ETERNUS storage systems deliver the capability to improve capacity utilization. Improved capacity utilization means reduced power demand which results in cost savings. All of the ETERNUS storage systems support ECO mode based on MAID (Massive Array of Idle Disks) technology that spins down infrequently accessed RAID groups. With effective use of ECO mode customers may realize power saving of 20% or more from their ETERNUS storage system.
