Brocade Data Center Reports 75% Energy Savings With New Custom Cooling System by Leading Technology Providers

CMI CMSCustom Mechanical Systems (CMS), a leading provider of custom cooling/HVAC solutions for mission-critical facilities including data centers, laboratories, cleanrooms and hospitals, along with Critchfield Mechanical (CMI), the largest design build mechanical contractor in California, announced today that they have provided Brocade(R)  with critical technology for use at their new state-of-the-art data center.

The Brocade San Jose-based data center incorporates technology from CMS and CMI that provides a cutting-edge in-row cooling system with water-side economizer to minimize fan usage and maximize efficiency, saving half a megawatt of energy at full build-out. The custom cooling system from CMS and CMI has played a key role in the Brocade data center, featuring fan efficiencies superior to all other cooling options available on the market today.

“Working to build a custom solution as a team with Brocade and CMI, we delivered a superior product with higher efficiency at a low first cost,” said Dan Hyman, co-founder and principal at CMS. “We’re thrilled to be a part of one of the most energy-efficient data centers in the country, and that our custom cooling technology is helping to make that possible.”

“Building a solution customized to the client’s design needs is rewarding,” said Jennifer Fraser, project manager for CMI and engineer of record on the Brocade project. “The ability to alter and define a product, rather than be restricted by out of the box solutions was critical to the success of our team.”

Brocade’s data center and its use of custom in-row cooling units, coupled with a highly efficient chilled water plant inclusive of a water-side economizer, provides a mechanical system with a power usage effectiveness (PUE) of less than 1.3. Data centers of this size typically have a PUE of greater than 1.5. To ensure a fully-customizable and flexible product, multiple iterations of the design were produced in order to meet Brocade’s specifications; CMS also worked with the construction team to design features that will simplify maintenance and improve reliability. These features include variable speed ECM motors, fan redundancy, and a low-cost maintenance design.

“CMS and CMI have helped Brocade achieve its goal of creating a data center that represents excellence in consolidation, energy efficiency, sustainable design and technology innovation,” said Michael Hirahara, Vice President, Global Real Estate, Facilities and Services at Brocade. “They were able to provide a cost-effective, customizable in-row cooling solution that uses 75% less energy than other available designs.”

Brocade consolidated three San Jose-area data centers into its new 5,000 square-foot, state-of-the-art facility, decreasing the physical footprint requirement by 30 percent and decreasing its data center energy consumption by 37 percent. With standardized management of cooling, power management and space management, the data center is designed to significantly reduce operating expenses and deliver long-term cost savings.
