•
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 Net-
work Time Protocol (NTP) server in the date and time setting in ETERNUS Web GUI to set au-
tomatic 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 activation 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 tem-
perature in the storage system. Collected information is notified using SNMP and graphically dis-
played on the screens by ETERNUS SF Storage Cruiser. Cooling efficiency can be improved by un-
derstanding local temperature rises in the data center and reviewing the location of air-condition-
ing.
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.
