Description

Related Application

This application claims the priority of U.S. Patent Application 14 / 757,865 entitled "POWER MANAGEMENT CONTROL OF REMOTE SERVERS" filed on December 24, 2015.

Technical area

This application relates to the technical field of data processing, in particular to methods and devices associated with the remote control of power management of remote computing servers.

Background of the invention

The background description provided herein is for the general presentation of the context of the disclosure. Unless otherwise indicated in the present specification, the materials described in this section are not prior art with respect to the claims in this application and are not recognized as prior art by inclusion in this section.

Large information technology (IT) applications can span hundreds of servers in data centers whose annual electricity bills are in the order of hundreds of thousands of dollars. Because server power usage is difficult to predict in advance, servers in data centers are typically used with an excessive power purchase commitment, and data center customers often pay the utility bill for the overcharged obligation. According to calculations by the Uptime Institute, the initial investment cost of a data center for each kilowatt of power installed is about $ 10,000 - a sum that would be sufficient to power two servers without any special measures.

For example, the DCM control module 115 , an energy management policy on a number of other servers 110 apply in the same data center as the customer server 108 can be operated. By applying an energy management policy to servers 110 can be the cloud customer server 108 Provide cost savings for the data center by placing loads on some servers 110 increased to others of the server 110 Shut down for a net energy saving. At block 204 For example, the cloud customer server 108, e.g. For example, the DCM control module 115 , a discovery to a cloud service provider through requests from the cloud management server 120 , z. Via IPMI or Redfish API, regarding the availability of cloud servers 122 and a record of their energy management services. At block 206 can cloud management server 120 Cloud Servers 122 query to determine which of cloud servers 122 may be available and / or activated to provide energy management services. For example, the cloud management server 120 each of the cloud servers 122 to determine what any available capacity it has and whether the server includes a power management control. At block 208 anyone can use the cloud server 122 perform a diagnostic check or self-poll to determine its current capacity to handle additional workload and to determine which power management services are available. At block 210 anyone can use the cloud server 122 to the request from the cloud management server 120 respond with data or a list indicating its available capacity and indicating which power management services the cloud server 122 can provide.

At block 212 can be the cloud management server 120 create a record of the availability of the cloud server 122 and includes energy management services provided by each of the cloud servers 122 Are available. The cloud management server 120 may include additional information in the record. For example, the cloud management server 120 IP addresses include each of the cloud servers 122 assigned. In particular, the IP addresses may provide access to power management controls residing in the cloud servers 122 may be included. The cloud management server 120 may create the record that includes additional information such as passwords, other identifiers for accessing the cloud servers 122, and / or API calls to the cloud customer server 108 to enable energy management services of cloud servers 122 to influence.
