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 disks
motor or the disks power can be turned on and off according to the backup operation state using ETERNUS SF
AdvancedCopy 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. 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 monitor-
ing the degree of changes in power consumption and temperature.
