Virtual machine migration according to environmental data
First Claim
Patent Images
1. A method, comprising:
- receiving, at a controller, temperature data for servers in a data center, wherein receiving the temperature data comprises receiving inlet and outlet temperatures of the servers;
migrating, by the controller, a virtual machine from a first server to a second server to reduce a temperature at the first server;
collecting supply air temperatures for one or more computer room air conditioning (CRAC) units in the data center;
using, by the controller, the supply air temperatures and the inlet and outlet temperatures to determine an area in the data center to move the virtual machine to reduce cooling costs for the data center.

6. A non-transitory computer readable medium having instructions for causing a computer to:
-
receive inlet and outlet temperatures of servers in a data center; receive supply air temperatures of plural computer room air conditioning (CRAC) units in the data center; migrate virtual machines among the servers to increase cooling efficiency in the data center, wherein the migrating is based on the inlet and outlet temperatures and the air supply temperatures. - View Dependent Claims (7, 8, 9, 10, 11)
