Data Center Solution

GDIT is a systems integrator that provides IT systems engineering, professional services and simulation and training to customers in the defense, intelligence, homeland security, federal civilian government and commercial sectors.

GMS performed the mechanical and electrical design, installation and commissioning of a new power and cooling infrastructure solution within GDIT’s data center room located in Fairfax, VA. The cooling system consisted of an air-cooled chiller; APC In-Row cooling infrastructure; chilled water loops that were sized for growth; chilled water buffer tank; redundant parallel electrical feeds; transfer switch; initial 80kw UPS; separate wiring closet ventilation unit; and a separate solution which is now back up for the primary cooling solution consisting of  two up-flow, close-control air-conditioning units with associated dry cooler, dual pump package and electrical upgrades.

The mission critical infrastructure solution was integrated with no major downtime for the customer, despite the data center being located in the middle of an 8 storey building, which necessitated installing hundreds of feet of piping and electrical circuits.

GMS selected the APC In-Row cooling units for this project which provided GDIT with added redundancy; a more flexible cooling design for future growth; and a more energy efficient solution which translates into large savings.
