Hitachi COMPUTE BLADE 500 SERIES Management Module Setup Manual page 245

In SMP configuration, each server blade operates with the primary server
blade settings. You need not to perform setting for non-primary server
blades.

Setting EPC/APC values
The following example shows the power management flow of the APC when
the maximum power consumption is set to 2000W with power capping
disabled at two blades.
The system specifications for the example are as follows:
• APC maximum for the system unit: 2000 W
• Power consumption for modules other than server blades: 800 W
The maximum power consumption for server blades: 1200 W
• Power consumption specification for server blades:
Rating power consumption (Maximum): 400 W
Maximum power consumption when capping to the minimum value: 150
W
• Number of server blades installed: 4
• Disabled APC for server blade 0 and 1
When the total power consumption of the chassis exceeds the APC
maximum, power consumption of sever blade 2 and 3 will be limited to
200 W respectively. That is because 400 W x 2 for rating power
consumption of server blade 0 and 1 with power capping disabled is
subtracted from 1200 W, and the remaining 400 W is shared by server
blade 2 and 3, 200 W per blade.
Note: When rating power consumption of server blades with power capping
disabled is subtracted from the server blade maximum power consumption
and the remaining value is shared by other server blades, power capping
cannot be disabled if the remaining value is less than the maximum power
consumption when capping to the minimum value. See the following
example.
• APC maximum for the system unit: 2000 W
• Power consumption for modules other than server blades: 700 W
The maximum power consumption for server blades: 1300 W
