Our state-of-the-art data centers...
Our primary data facility is located within the CoreSite Data Center in Los Angeles, California. Our secondary data facility is located within the CoreSite Data Center located in Somerville, Massachusetts.
CoreSite’s Los Angeles data center is located in downtown Los Angeles. The 450,000 square-foot facilitiy is one of the premier data centers that you can find on the West Coast. This facility has the concrete, power and network access commensurate with the world’s great data centers. Accommodating live loads of 160 pounds per square foot, CoreSite’s Los Angeles data center exceeds minimum Seismic Zone 4 and Site Coefficient requirements by up to 15%, a fact reflected in its low insurance PML rating.
CoreSite’s Boston data center located just outside of Boston's Central Business District in Somerville. This 276,000 square-foot facility is one of the premiere data centers that you can find on the East Coast. This facility features diverse power and fiber points of entry, including access to over 20 onsite carriers and service providers as well as 100+ service providers.
The CoreSite data centers are highly secure with 24x7 manned security and biometric scanners. CoreSite staffs the site 24x7 with credited operational personnel to complete remote hands tickets, data center build-outs, cross connections and deliveries. Both locations are SAS 70 Type II-certified and exceeds the stringent standards for security and operations that Sarbanes-Oxley, HIPAA, Gramm-Leach-Bliley and other regulations require.
Cabinet, Device and Cabling Specifications
Further security of operations is ensured by encapsulating devices within dedicated cage spaces preventing unauthorized access to the monitored and locked cabinet-style racks and devices. Power cables and all network cables have been secured in conduit for added security. The front and back of each cabinet is monitored and recorded by multiple closed circuit surveillance cameras.
The data center's average temperature of 70-72 degrees Fahrenheit with 45 percent humidity is achieved through the use of 86 Airflow rooftop mounted compressed gas units (N+1). This feeds to the 86 Airflow CRAC units that supply the data center with the cool dry air pushed through the perforated floor tiles. Each unit is 28 tons, for a total of 2,408 tons of installed cooling. Each condenser also has an associated water sensor to identify any failures.
Data Center Power
The data center receives primary power feeds from two separate substations which feed into the facility through separate underground routes. The primary feeds connect to separate electrical service switchboards which are crossfed with secondary ties that feed into separate MGE UPS (Uninterruptible Power Supply) Systems. Each redundant UPS room contains 6 UPS systems (N+1) which filter out aberrations to supply clean continuous power to the customer cabinets, and infrastructure equipment.
Each UPS is connected to six two-megawatt Cummins Diesel Generators that will activate within eight seconds of power failure. Twenty four thousand gallons of fuel reside on-site to provide enough fuel to run all six generators at 100 percent capacity for 48 hours. While no condition exists in which all generators would operate under such conditions, a reference of scale would be to consider that operation of all six generators simultaneously would produce enough excess power to feed the entire local electrical grid. Power system testing includes testing of emergency switch gear at least semiannually through simulated power loss. UPS systems are tested on a monthly basis and generators are tested weekly. While the facility has experienced grid power loss, no customers have ever been affected by an outage.
A pre-action (dry pipe) sprinkler system with pressurized leak down detection has been installed above the floor throughout the data center and subdivided into multiple zones. Early warning smoke, particle and heat detectors are located above and below the floor to detect any potential problem. The system is connected to a 24/7/365 monitoring service both on and off-site. The system will only charge the sprinkler system once two detectors in a zone have been triggered. Once triggered, the thermal fuse in each sprinkler head must reach between 120 and 190 degrees to disperse water. In addition, FM-200 extinguishers are located throughout the data center to attack incipient fire outbreaks prior to sprinkler system activation.
