Solution Overview
Power consumption can be reduced by stopping disk motors when they are not being used. Making power
consumption more efficient reduces the cost of electricity, noise emissions, and CO
2
emissions.
If the backup time period is predetermined, power saving operations can be implemented effectively by set-
ting the Eco-mode schedule for backing up disk drives to only activate the disks when required. The disk mo-
tors can be also turned on and off to match the status of backup operations by using ETERNUS SF Advanced-
Copy Manager.
The graphical display when ETERNUS SF Storage Cruiser is used makes it easy to understand changes in pow-
er consumption and in temperature as well as check the effect of power saving operations and the effect of
air conditioning around the ETERNUS DX Disk storage system. This statistical data can be output to a file so
that it can be used when planning which power supply equipment and air conditioning equipment should be
used by monitoring the degree of changes in power consumption and temperature.
