HP Power Capping and HP Dynamic Power Capping for ProLiant servers

Setting a power cap for a group of enclosures

An administrator can use Insight Control to apply enclosure dynamic power caps to a group of enclosures at the

same time. Figure 9 shows five BladeSystem c-Class Enclosures configured as a group in Insight Control. The

maximum available power for the group is 31,784 watts. The lower bound of the power cap is 15499 watts. It is

higher than the maximum power measurement because it represents 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 Insight Control and the OAs to create and apply a separate Enclosure Dynamic Power Cap to each of the

five 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
