Determining location of hardware components in a cloud computing environment based on hardware components self-locating other hardware components
A method, system and computer program product for managing hardware components in a cloud computing environment. Each hardware component in a data center of the cloud computing environment detects and identifies other hardware components within a communication range of the hardware component using a wireless protocol. Furthermore, each hardware component determines its actual location as well as its relative location with respect to the detected hardware components, such as based on a triangulation of the wireless signals. Such information is transmitted to an administrative server. An inventory of the hardware components in the data center, including their current location, is then compiled by the administrative server. In this manner, a hardware component can be more easily located after being relocated in the data center. Furthermore, the administrative server will be able to balance a workload across these hardware components based on their location.
1. A method for managing hardware components in a cloud computing environment, the method comprising:
receiving location information for said hardware components in a data center of said cloud computing environment from said hardware components, wherein said location information for each of said hardware components comprises both an actual location and a relative location with respect to one or more other hardware components in said data center, wherein each of said hardware components is configured to detect one or more other hardware components within a communication range of said hardware component, wherein each of said hardware components is configured to determine its actual location and a relative location with respect to said one or more detected hardware components;
receiving identification information of hardware components detected by said hardware components from said hardware components, wherein each of said hardware components is configured to identify said one or more detected hardware components based on an identification signal received from said one or more detected hardware components; and
balancing, by a processor, a workload across said hardware components in said data center based on said received identification and location information.
2. The method as recited in claim 1 , wherein one or more of said hardware components are configured to determine its relative location with respect to its one or more detected hardware components based on a triangulation of wireless signals.
3. The method as recited in claim 1 , wherein one or more of said hardware components are configured to determine its actual location based on wireless signals received from devices at fixed locations.
4. The method as recited in claim 1 , wherein a distance from a hardware component of said hardware components to a detected hardware component is determined based on relative signal strength.
5. The method as recited in claim 1 , wherein each of said hardware components is configured to detect said one or more other hardware components within said communication range of said hardware component using a wireless protocol comprising one or more of the following: radio frequency identification, Bluetooth®, IEEE 802.11 and cellular communications.
6. The method as recited in claim 1 , wherein said workload is balanced across said hardware components in said data center based on one or more of the following policies: balancing heat distribution across said data center, consolidating workloads to co-located systems, and balancing network hops and available bandwidth across said data center.
