| 摘要 |
Methods, apparatus, and products are disclosed for providing position information to computing equipment installed in racks of a datacenter that includes: projecting, by a projection module, a plurality of optical signals to a plurality of reference points on at least one reflective surface above the racks of the datacenter, each optical signal corresponding to one of the reference points and encoding reference point position information for that corresponding reference point; detecting, by a position detection module mounted on one of the racks, one or more of the optical signals reflected off of the reflective surface; determining, by the position detection module, rack position information in dependence upon the reference point position information; and providing, by the position detection module, the rack position information to a position information consumer that uses the rack position information to identify the position of the rack on which the position detection module is mounted.
