Abstract
Certain aspects of a method and system for managing network power policy and configuration of data center bridging may include a network domain that comprises a single logical point of management (LPM) that coordinates operation of one or more devices, such as network interface controllers (NICs), switches, and/or servers in the network domain: The single LPM may be operable to manage one or both of a network power policy and/or a data center bridging (DCB) configuration policy for the network domain.
Claims20
A network domain device comprising:
- a plurality of communication devices, each respective communication device of the plurality of communication devices including one or more circuits configured for data communication according to respective communication parameters designated for each respective communication device of the plurality of communication device, each respective communication device of the plurality of communication devices having a respective power mode and a respective operation mode;
- and
- a logical point of management configured for data communication with communication devices of the plurality of data communication devices, the logical point of management including one or more circuits configured to determine a respective power mode and a respective operation mode for each respective communication device, the one or more circuits of the logical point of management further configured to subsequently adjust the respective communication parameters for communication among the respective communication devices according to communication performance requirements for communication among the respective devices in said network domain among a plurality of modes relating power consumption and communication performance of the respective devices.
A network domain device comprising:
- a plurality of communication devices, each respective communication device of the plurality of communication device including one or more processors programmed for data communication, each respective communication device of the plurality of communication devices having a respective power mode and a respective operation mode;
- and
- a logical point of management including one or more processors programmed for data communication with each communication device of the plurality of data communication devices, the one or more processors of the logical point of management programmed to determine a communication configuration for the network domain device and to establish a data center bridging policy based on the communication configuration, the local point of management further configured to identify a conflict among respective communication devices due to the established data center bridging policy and to arbitrate the conflict for the respective devices based on a minimum bandwidth available.
A method comprising:
- at a network domain device including a plurality of communication devices, receiving a network power policy for configuration of data center bridging;
- based on the received network power policy, selecting a mode of operation for the network domain device from among at least a best performance mode, a normal mode and a minimal mode of operation;
- for the selected mode of operation for the network domain device, establishing a domain level or sub-domain level power maximum and establishing power average capping;
- and
- adjusting power states of the plurality of communication devices.
