HP ML150 HP Power Capping and Dynamic Power Capping for ProLiant servers techn - Page 16

Setting a power cap for a group of enclosures An administrator can use Insight Power Manager to apply enclosure dynamic power caps to a group of enclosures at the same time. Figure 9 shows six BladeSystem c-Class Enclosures that have been configured as a group in IPM. The maximum available power for the group is 39,460 watts. The lower bound of the power cap is 21,417 watts and is higher than the present maximum power measurement because it is calculated to represent the lowest reasonable power cap for the group that is sustainable under all operating conditions. Applying a power cap value of 25,000 watts to the group causes IPM and the OAs to create and apply a separate Enclosure Dynamic Power Cap to each of the six enclosures, using the same proportional allocation method described earlier for applying a group power cap to ML and DL servers. The OA within each enclosure will use this power cap to determine a blade power budget for the enclosure and to create power caps for the individual server blades. It will then continue to monitor and adjust the individual server blade power caps based on their power demands. Figure 9. Setting a power cap for a group of enclosures in IPM 16
