| Q1. |
What is the difference between Power Capping and Dynamic Power Capping? |
| A1. |
Dynamic Power Capping limits power consumption with circuit protection whereas current power capping and competitive power management solutions cannot provide circuit protection at the rack PDU level. Dynamic Power Capping is able to provide this protection by anticipating potential power overages and capping consumption within one second.

| Q2. |
Does Dynamic Power Capping provide special capabilities for BladeSystem evironments? |
| A2. |
Yes. In BladeSystem environments, customers will set an enclosure Dynamic Power Cap in the Onboard Administrator or via Insight Power Manager. This will allow blades that require more power to request it from other blades in the enclosure. The net result is as much as a 20% improvement in the number of servers that can be added to a specific BladeSystem enclosure or group of enclosures.
|
|
| Q3. |
Why is there a 20% improvement when using Dynamic Power Capping at the BladeSystem enclosure level? |
| A2. |
When implementing Dynamic Power Capping at the BladeSystem enclosure level, the Onboard Administrator takes advantage of the fact that server utilization (and power consumption) will vary from blade to blade within the enclosure. By temporarily borrowing power from idle blades and assigning it to busy ones, it is possible to provide the required level of power to all blades in the enclosure without performance degradation.
