Our Data Center

Internet Carriers: Mammoth Networks, Sprint, Internap, Hurricane Electric, XO Communications, Rocky Mountain Internet Exchange, Qwest, Level 3, Cogent, and Global Crossing.

AC Power Feed: The Xcel Energy power is delivered via an Xcel Energy transformer secondary rated at 2000Kva/1600Kw, 480Vac/277Vac, 3 phase, 4Wire located in the parking lot with a single input feed. The delivery to the main distribution center (MDC) located in the data center power room is off of switch gear which is rated at 800 amps @ 480Vac, 3 phases and located on an exterior wall of the building.

DC Plant: Lorain Marconi -48Vdc, 2400 amps. The data center can deliver up to 1920 amps, 960 amps “A” and 960 amps “B”. It has two parallel battery strings for support each having disconnects for maintenance. Each battery string consists of twenty four, 2Vdc batteries in series. The 48Vdc is used to maintain the voltage during an input power outage. There is enough battery capacity for at least 4 hours of operation. Two strings in parallel allows for one battery to fail, battery servicing, etc., and not result in disruption of service. DC distribution is through eight 250 amp -48Vdc breakers. The AC input power is from multiple 30 amp, 480Vac, 3 phase breakers located in the (MDC) located in the data center power room. Conditioned power with redundant UPS and cooling

Uninterruptible Power Source (UPS): PowerWare 9315 80/80, 80Kva/64Kw unit, output of 208Vac/118Vac, 3 phases and a Liebert 125Kva/102Kw UPS unit, output of 208Vac/118Vac, 3 phases. They are supported by two parallel battery strings for each UPS. Each battery string consists of forty, 12Vdc batteries in series. The 480Vdc is used internally to the UPS to maintain the output voltage during an input power outage. At full load, there is enough battery capacity for at least 20 minutes of operation. Two strings in parallel allows for one battery to fail, battery servicing, etc., and not result in disruption of service. The AC input power to the UPS’s are from the (MDC) located in the Colocation Facility data center power room. The maintenance bypass cabinet is for the Liebert UPS. Its output rating is 600 amps @ 208Vac/118Vac.

Generator Backup:  A power generation plant which consists of one, Cummins/Onan 800 amp, 480Vac/277Vac, 625Kva/500Kw 3 phases, diesel powered generator. The generator, fuel storage, and distribution system are located in the parking lot. The generator has a 1600 gallon fuel tank which is maintained at least 60% capacity. With the current loads, there is enough fuel for at least 24 hours of operation. The generator is controlled by an Automatic Transfer Switch (ATS) in the data center power room.

CRAC: Liebert Deluxe System 3: The datacenter has three 20 ton upflow computer room air conditioning units in the larger room and two 10 ton upflow computer room air conditioning units in the smaller room. The piping has been installed for a fourth 20 ton unit, allowing for an easy enhancement to the system. The AC units are controlled by an Auto-Changeover controller. This controls how many of the units are running, rotation cycles, and failover. The following pieces are located on a steel platform on the roof inside of a shed style enclosure: There are two water pumps and they each have a controller and are designed for redundancy. There is also a main controller unit which handles the rotation cycles and failover of the pumps. The Dry Coolers consist of three units, 6 fans per unit and are elevated on the platform for good air circulation.

Fire Suppression:  Dry pipe, double interlock pre-action fire sprinkler system. Dry-Chem fire extinguishers are also located throughout the facility for added protection.

Humidity: Electrode steam humidifiers are designed into the CRAC units. These are designed to provide clean steam humidification.

Temperature and Humidity Monitoring: Sensatronics Environmental Monitors and Probes. The monitors are network ready and have an internal web server and the probes are accurate to .5dF. The data center has 6 temperature probes located throughout the data center
monitoring the hot and cold aisles.

Physical access is controlled by a HID access control system. HID cards are issued after obtaining a copy of the driver’s license, a photo, and an application has been completed.

Video Surveillance: The Colocation Facility uses two different systems for recording of activity inside and outside of the data center. Our first system uses IP cameras that have motion detection, FTP capabilities, and a web server. These cameras are located in the most
sensitive areas of our data center. Images from these cameras are uploaded to a server. Our second system uses color cameras and a DVR. The DVR is setup to record images as motion is detected and the cameras are located throughout the data center.
