Harris Corporation recently earned Uptime Institute Tier III Facility Certification for its new Mid-Atlantic data center, the Cyber Integration Center. The new facility is the foundation for Harris’ Trusted Enterprise Cloud services.

Uptime Institute Vice President Julian Kudritzki spoke at the ribbon cutting ceremony for the new Harris data center.

Concurrent maintainability for Harris Cyber Integration Center

According to Uptime Institute Professional Services Consultant Chris Brown, the chilled water system is a typical solution for a Tier III data center. It is a looped piping system with strategically located isolation valves to allow sections of the piping system to be isolated for maintenance without impacting the computer rooms. The chiller-cooling tower combination utilized packaged units. The packaged units ease the design to make the control system Concurrently Maintainable. In large condenser water systems, it is difficult to operate the cooling towers without automatic control since condenser water temperature typically needs to be held in a fairly tight window. This makes running cooling towers in a local manual mode difficult. The packaged systems use on board controls that are independent of the larger building automation system.

The interesting part is the UPS system, Brown said. A typical Tier III solution is to utilize a System + System arrangement. So if the design load was 1,000 kW the design would utilize two 1,000 kW systems. The management of that type of system is easy as one only has to ensure that each dual corded computer device has a feed from each UPS. But the cost is a 50% stranded capacity (45% with a 90% redline). Also static UPS systems do not run at peak efficiency the lower they are loaded.

The Cyber Integration Center used a different approach, utilizing five separate UPS systems. By evenly distributing dual corded loads across all five UPS systems the UPS systems can be loaded to 67% in normal operations. With a loss of a single UPS the total load on each UPS will increase to 83%. This allows each UPS to be loaded to a higher utilization under normal operations. This results in less stranded capacity. Also by increasing the percent utilization, the static UPS will operate at a higher efficiency than at a lower utilization. This system is more complex to manage as the dual corded loads must be evenly distributed across all UPS systems, but the result is less stranded capacity and higher efficiency.

This facility also won an Uptime Institute Green Enterprise IT award for water usage efficiency.

Congratulations to Harris on earning Uptime Institute Tier III Certification.

Data center case studies online: 2011 GEIT Award Winners

Every year Uptime Institute hosts the Green Enterprise IT (GEIT) Awards, an international competition that recognizes projects, ideas and products that improve energy productivity and resource use in IT. Although the categories in which the Institute grants Awards may change each year, the objectives remain the same: to educate the data center and IT industries in effective ways to reduce energy consumption by shining a spotlight on innovation and best practice. Through the GEIT program, we want to recognize and support change agents who lead by example.

GEIT is no popularity contest; our rigorous judging process is designed to select projects that demonstrate groundbreaking ideas that produce quantifiable, high impact results. GEIT applications are evaluated by a panel of independent, expert judges. To insure objective evaluation, applications are reviewed in a double-blind process: judges do not know whose applications they review, and applicants do not know which judges reviewed their application. In addition, the staff ensures that Judges are not allowed to judge any Award category that includes applications from his or her own company.

Another unique feature of the GEIT Awards is the benefits winners and finalists receive: GEIT honorees are provided a platform to share what they’ve learned on the world stage. The Institute offers each winner a 30-minute session at its spring Symposium to present their case study and complimentary registrations so representatives from winning companies can network at Symposium and share what they’ve learned with peers. Finalists, likewise, are provided a free registration and are invited to present a brief overview of their projects. As in all Symposium sessions, GEIT honorees engage in Q&A with delegates after their presentation to encourage collaboration and knowledge sharing.

And case briefs and presentations are hosted on the Symposium website for the benefit of the global community. Uptime Institute is proud to present the following nine data center case studies that that significantly improve energy productivity and resource use in IT.
