• Sacramento CA2 Data Center

California colocation near the Bay Area and Silicon Valley

NTT's west coast data center in Sacramento, California called "The Rock℠" is the largest data center in the state of California with over 52.7 MW of high density critical IT capacity spread across three fully integrated buildings CA1, CA2 and CA3 totaling 680,000 sq. ft. of data center space.

The Rock data center services include mission-critical colocation, telecommunications, design and installation, security and project management. NTT Global Data Centers Americas technologically advanced, patented electrical infrastructure offers 2N+2® redundancy which exceeds the Uptime Institute's Tier IV standard for electrical delivery because it provides both concurrent maintainability and fault tolerance. Unlike Tier IV standard designs, NTT Global Data Centers Americas maintain fault tolerance while maintenance is underway. This system provides the highest level of provable availability in the industry, and it allows NTT Global Data Centers Americas to offer wholesale customers the most robust Service Level Agreement (SLA) in the industry: 100% Availability with no exclusions for maintenance.

CA2 is LEED Gold certified and EPA ENERGY STAR rated, with one of the lowest PUEs in the industry. CA1 and CA2 data centers are largely filled with retail and large wholesale clients.
