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.
