534 modulating perf tiles? What energy source actually modulates the tile louvers? How much additional cost is associated with the acquisition, installation, balancing, and periodic maintenance of these tiles? Historically manually modulated perf tiles typically get bound up and fail in one position. Is there a new material or louver mechanisn being deployed to reduce the lifetime maintenance costs associated with modulating tiles?

@Rick Merritt: good article. It is interesting that they chose to use Modbus for networking facility sensors to their supervisory/monitoring/control interface (which I assume uses a function similar to an NMS: network management service). Looking at the number of facility servers (temperature sensors, electricity sensors, water temperature, flow sensors and humidity sensors), looks like they used several Modbus networks to link these together. The electricity sensors can be linked directly to their Ethernet links for NMS circumventing the Modbus connection. I was curious: the airflow openings in the floor tiles, are they controlled in a closed-loop system with feedback from temp sensors? Or, are they manual? Also, if you get an opportunity, I would love to learn about a similar expose on any of Google's data centers! Dr. MP Divakar
