12 September 2007 — Data centers strive for high availability but unlike other mission-critical facilities, data centers are typically built with commercial DDC control systems.
Control systems have been identified as the most frequent source of HVAC system problems. Industrial control systems differ from commercial systems in their use of more accurate and rugged sensors and devices, signal types and wiring methods. Industrial controllers are more robust, have higher performance, faster networks and more flexible programming capability. Redundancy options with industrial controls can address the most difficult control issues without relying on “passive automation”. A data center design is presented which includes industrial grade sensors, redundant PLC processors, redundant PLC I/O network, redundant SCADA servers and remote programming and monitoring capability over the internet.
