2. Contract or Task Order Title. DISA Computing Center Oklahoma City Raised Floor and High Density Cooling & Power Upgrade

3. Background.

DISA Computing Centers provide routine and mission-critical computer processing resources and support to numerous Government agencies, 24 hours per day and seven (7) days a week. DISA’s operational goal is to provide high availability and redundancy to all supported programs and workloads at a Tier III redundant datacenter. The Oklahoma City computing center needs repairs and upgrades to the raised floor and high density cooling and power solutions for new information technology (IT) missions. The existing raised floor panels are wood core and must be replaced with concrete core panels for fire protection and higher floor load capacity, to meet the DOD standards.

DISA computing centers are laid out with a traditional hot aisle/cold aisle equipment rack configuration. The rack aisles are not enclosed with doors or a ceiling. The aisles are open and the rooms are typically kept cool. This is effective for racks that generate under five (5) kilowatts of heat load. Racks that generate higher kilowatts of heat require exploration of different cooling alternatives. The best way to do this is enclosing the racks in a cold aisle configuration. The cold aisle containment enclosures with IRCs provide a higher concentration for cooling the high density IT equipment racks. Additionally, another new IT mission requires secure space to be powered and cooled in a standard computing room configuration with static transfer switch (STS)/PDU pairs and CRAHs.

4. Objectives.

Upgrade the raised-access floor by replacing all access floor panels with concrete core panels; and upgrade or modify, as needed, the access flooring structure to support a floor load of 2500 pounds per square foot (psf). Clean the structural floor during the access floor replacement and upgrade the signal reference grid grounding system. Provide and install six (6 each) cold aisle containment enclosures for DISA computer equipment racks in Computer Room 147 in the southwest corner as referenced in the Design Concept Drawings at Appendix A. The racks will be arranged in linear configurations with six feet separating two rack rows. The contractor shall fully enclose six cold aisles of the proposed linear rack configurations with containment systems, complete with doors and retractable ceiling. The contractor shall provide, install, and connect eighteen new 40-kilowatt (kW) IRCs, three in each enclosure, with two (2 each) cold water manifold distribution units that will support the IRCs. Underfloor differential pressure sensors and controls shall also be installed and integrate on specified existing CRAHs. The contractor shall also provide, install, and connect a total of 16 200kVA static transfer switch/power distribution unit STS/PDU sets to support the IT equipment. Four STS/PDU sets shall support the new enclosures.
