Abstract

Methods, system, and computer program products are provided for determining redundancy of power feeds connecting a server to a power supply. Embodiments include receiving, by a redundancy monitoring manager, from each of a plurality of redundancy monitoring interposers, connection information, wherein each redundancy monitoring interposer comprises a device that provides an electrical contact between a power circuit and one of a power supply, the server, and another power circuit; in dependence upon the connection information, determining, by the redundancy monitoring manager, for each power feed provided to the server, which power circuits supply the power feed; determining, by the redundancy monitoring manager, if any of the power feeds are supplied by the same power circuit; and indicating, by the redundancy monitoring manager, that the server has at least one non-redundant power feed when multiple power feeds of the server are supplied by the same power circuit.

Claims

1. A method of determining redundancy of power feeds connecting a server to a power supply, the method comprising:

receiving, by a redundancy monitoring manager, from each of a plurality of redundancy monitoring interposers, connection information, wherein each redundancy monitoring interposer comprises a device that provides an electrical contact between a power circuit and one of a power supply, the server, and another power circuit;

in dependence upon the connection information, determining, by the redundancy monitoring manager, for each power feed provided to the server, which power circuits supply the power feed;

determining, by the redundancy monitoring manager, if any of the power feeds are supplied by the same power circuit; and

indicating, by the redundancy monitoring manager, that the server has at least one non-redundant power feed when multiple power feeds of the server are supplied by the same power circuit.

2. The method of claim 1, wherein the connection information received from a particular redundancy monitoring interposer identifies the power circuits that are connected to the particular redundancy monitoring interposer.

3. The method of claim 1, wherein at least one redundancy power interposer determines the connection information by communicating with one of a power circuit, the server, and another redundancy power interposer.

4. The method of claim 1, wherein indicating that the server has at least one non-redundant power feed includes displaying a visual representation of the power feeds for the server, wherein the visual representation indicates the non-redundant power feeds and the redundant power feeds.

5. The method of claim 1, wherein the redundancy monitoring manager is integrated within one of the redundancy monitoring interposers.

6. The method of claim 1, wherein the connection information is received wirelessly from the redundancy monitoring interposers.

7. The method of claim 1, wherein the connection information is received from the redundancy monitoring interposers through the power lines.
