•
Eco-mode schedules are executed according to the date and time that are set in the ETERNUS DX. To turn
on and turn off the disk motors according to the schedule that is set, use the Network Time Protocol (NTP)
server in the date and time setting in ETERNUS Web GUI to set automatic adjustment of the date and time.
•
If the number of drives that are activated in a single drive enclosure is increased, the time for system activa-
tion may take longer (about 1 to 5 minutes). This is because all of the disks cannot be activated at the
same time.
•
Even if the disk motor is turned on and off repeatedly according to the Eco-mode schedule, the failure rate
is not affected comparing to the case when the motor is always on.
Power Consumption Visualization
The power consumption and the temperature of the ETERNUS DX can be visualized with a graph by using the
ETERNUS SF Storage Cruiser integrated management software in a storage system environment. The ETERNUS
DX collects information on power consumption and the ambient temperature in the storage system. Collected
information is notified using SNMP and graphically displayed on the screens by ETERNUS SF Storage Cruiser.
Cooling efficiency can be improved by understanding local temperature rises in the data center and reviewing
the location of air-conditioning.
Understanding the drives that have a specific time to be used from the access frequency to RAID groups enables
the Eco-mode schedule to be adjusted accordingly.
