Abstract

The positions and relative locations of electronic devices located within an electronic equipment rack can be determined and mapped through the reading, by a mobile device, of near field communication (NFC) tags attached to the electronic devices. The mobile device can execute a method that includes reading and recording data values from sets of nearby NFC tags in conjunction with locations of the mobile device relative to a reference location. The method executed by the mobile device can include an algorithm to determine the absolute and relative positions of the electronic devices through processing of the inclusion or exclusion of NFC tag data within the sets of read NFC tag values. The absolute and relative positions of the electronic devices can be subsequently used to create a map depicting the position of the electronic devices within the electronic equipment rack.

Claims

1. A system comprising:

an electronic equipment rack housing a plurality of electronic hardware devices;

the plurality of electronic hardware devices being operatively connected within the electronic equipment rack;

a set of near field communication (NFC) tags, each NFC tag of the set of NFC tags attached to, and containing a unique serial number of, a corresponding electronic hardware device of the plurality of electronic hardware devices operatively connected within the electronic equipment rack; and

a mobile device comprising an NFC tag reader to read a set of data values from the set of NFC tags, the set of data values including unique serial numbers contained by the set of NFC tags, the mobile device further configured to measure a distance between a location of the mobile device and a reference location, and to record the set of data values read from the set of NFC tags in association with recording the distance to facilitate locating electronic hardware devices of the plurality of electronic hardware devices operatively connected within the electronic equipment rack.

2. The system of claim 1, wherein the mobile device is selected from the group consisting of:

a cell phone, a smartphone and a tablet device.

3. The system of claim 1, wherein the mobile device includes a camera configured to determine a distance between the mobile device and the reference location.

4. The system of claim 1, wherein each electronic hardware device of the plurality of electronic hardware devices operatively connected within the electronic equipment rack is selected from the group consisting of:

a server, a data storage device, a network device and a processor.
