Consulting-Specifying Engineer - March 2009 - (Page 17) M/E/P Roundtable Lane: One trend we are seeing more of is modular/containerized systems. We have been involved in the design of containerized data centers. These systems offer several advantages including: • Quick deployment • Minimum upfront cost • Optimum use of outside air, which can reduce PUE • Potential use of multiple server technologies. I do not think the modular/containerized data centers will take over the conventional brick-and-mortar data center, but these systems do have their place in the critical environment systems of the future. Berry: An arrangement we see more often is a centralized standby genera- tion plant with local controllers installed in separate fire-rated rooms that mitigates against any single point of failures. The centralized standby generation plant can be operated at its maximum Ryan: Standby power has not changed much, but the equipment has become more sophisticated over the years in the area of monitoring.

Centralized power conditioning systems should be configured using a distributed electrical system where the load is distributed across all the conditioning units. This enables each power conditioning unit to be operated at maximum efficiency. age over batteries. They are less expensive to maintain and take up less space than batteries. The biggest changes in UPS over the past few years have been the steadily increasing efficiencies and more modular approaches to deploying capacity, all of which are great for the data center.
