Abstract

An energy management system for a data center network may include a central computer to establish an energy use policy for the computer data center network. The system may also include computer nodes in the computer data center network to receive a packet which is a query that obtains energy information from the nodes and/or a transmission reservation that provides instructions for the energy use policy to be implemented at the computer nodes. The computer nodes may reallocate data traffic on the computer data center network based on the energy use policy to improve energy consumption of the computer data center network.

Claims

1. A method comprising:

establishing an energy use policy for a computer data center network;

transmitting a packet to computer nodes in the computer data center network that is at least one of a query to obtain energy information from the computer nodes and a transmission reservation to provide instructions for the energy use policy to be implemented at the computer nodes; and

reallocating data traffic on the computer data center network based on the energy use policy to improve energy consumption of the computer data center network.

2. The method of claim 1 further comprising using a load balancer to at least one of prioritize the data traffic and provide fairness in the reallocated data traffic.

3. The method of claim 2 further comprising providing fairness by permitting some quantity of lower priority data to traverse the computer data center network along with higher priority data.

4. The method of claim 1 further comprising enabling the improvement of energy consumption of the computer data center network by reducing at least one of the data traffic flow through some of the computer nodes, energy requirements of some of the computer nodes, and a number of the computer nodes used by the computer data center network during the reallocation of data traffic.

5. The method of claim 1 further comprising providing a central node to transmit the packet and a software agent at at least one of each computer node and the central node to collect the query data.

6. The method of claim 1 further comprising giving the transmission reservation priority control over the computer nodes rather than any other control measure on the computer data center network.

7. The method of claim 1 wherein the computer nodes comprise at least one of power supplies, data storage, climate controllers, communications links, and security units.
