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.
Claims16
A method for networking, the method comprising:
- in a network domain comprising a single logical point of management (LPM) that coordinates operation of one or more devices in said network domain, respective devices of the one or more devices in said network domain having respective power and operation modes:
- managing by said single LPM, a network power policy and a data center bridging (DCB) configuration policy for said network domain based on one or more parameters of a switch and a network interface controller (NIC) that are mismatched, including
- receiving the network power policy for the network domain,
- determining respective power and operation modes for the respective devices using the received network power policy;
- adjusting respective communication parameters for communication among the respective devices to satisfy performance requirements for said communication among the respective devices in said network domain among a plurality of modes relating power consumption and communication performance of the respective devices and also to satisfy the received network power policy;
- selecting a mode of operation of said one or more devices based on said managed network power policy for said network domain;
- and
- arbitrating between two or more conflicting DCB configuration policies for said one or more devices based on a minimum bandwidth available.

A system for networking, the system comprising:
- one or more processors or circuits for use in a single logical point of management (LPM) in a network domain, wherein said LPM is operable to coordinate operation of one or more devices in said network domain, said one or more processors or circuits being operable to:
- manage a network power policy and a data center bridging (DCB) configuration policy for said network domain based on one or more parameters of a switch and a network interface controller (NIC) that are mismatched, including
- receive the network power policy,
- using the received network power policy, determine a mode of operation for the devices of the one or more devices in said network domain among a plurality of modes relating power consumption and communication performance of the respective devices;
- adjust respective communication parameters for communication among the respective devices according to the determined mode of operation;
- selecting a mode of operation of said one or more devices based on said managed network power policy for said network domain;
- and
- arbitrating between two or more conflicting DCB configuration policies for said one or more devices based on a minimum bandwidth available;
- and
- from time to time, adjust the respective communication parameters dynamically according to the determined mode of operation and changes in communication performance and power setting for the network domain.
