摘要： In one or more embodiments of the invention, communication among host agents providing high availability in a computer cluster is implemented by reading and writing to files on a shared data store. Each host agent holds a lock on a file on the shared data store corresponding to a liveness indicator for the host agent and a coordinator host agent periodically monitors the liveness indicators for host failures.

摘要： A method for restarting a virtual machine in a virtual computing system having a plurality of hosts and a resource scheduler for the plurality of hosts includes writing a placement request for the virtual machine to a shared channel that is accessible by the resource scheduler. The method further includes reading a placement result from the shared channel, wherein the placement result is generated by the resource scheduler responsive to the placement request; and restarting the virtual machine in accordance with the placement result.

摘要： A system, method, and computer-readable medium for detection and avoidance of victim services in ultra-wideband systems is provided. A detect and avoid module may calculate power averages of OFDM tones. The power of tones may then be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The ultra-wideband subsystem may be configured with known bands of victim services of other RF systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.
