• Eco-mode schedules are executed according to the date and time that are set in the ETERUS
DX Disk storage system. 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.
• Up to eight 2.5" drives or four 3.5" drives can be activated at the same time in a single drive
enclosure. When these maximums are exceeded, the first eight 2.5" drives or four 3.5" drives
are activated, followed by the rest of the drives in matching increments for each size. If the
number of drives that are activated in a single drive enclosure is increased, the time for drive
activation takes longer, causing the response times for the server to increase, which may
result in access paths being lost. To prevent this from occurring, the RAID configuration and
drive installation must be taken into consideration.
