Located in Denver's central business district, the building of the datacenter has power feeds from multiple substations. Electrical service is connected to our Mitsubishi 375KVA UPS, which delivers conditioned power to the data center. In the event of a utility power failure, the diesel generator will immediately start carrying the entire data center load. Building life safety systems are backed up by a separate generator.
Cooling and humidity is controlled by 7 air handling units featuring N+1 redundancy. The HVAC units keep the operating environment in the data center at 70 degrees within 45% humidity with variation of no more than 4 degrees to temperature and 4% humidity. To ensure that optimal cooling and air circulation is available at all times, air flow studies are conducted and an analysis with infrared heat sensing cameras is performed on a regular basis. We also have local and remote environmental monitoring systems in place.
The data center facility is located in a building that has 24x7 on site security. After business hours, all individuals entering or exiting the building are required to present building credentials and sign in with onsite security staff. Upon doing so, they are only granted elevator access to the floor they need access to. Additionally, the datacenter have their own security system which consists of access control systems within the office suite and remotely monitored video surveillance.
Fire detection within the data center is provided by an early detection alarm system monitored both within the office suite and by the building's 24x7 security staff. The data center has detectors installed both above and below the raised flooring. The fire suppression system is a pre-action, dry pipe which would discharge water only from the appropriate locations when the heat in the data center increases enough to trigger a fire sprinkler head. The discharge of a sprinkler would signal the emergency power-off switch, which would simultaneously turn off the commercial electrical power to the data center and switch to UPS power.
Our network is powered by a pair of redundant Juniper M5 routers and Cisco 6500 series switches. All of the edge and core equipment is interconnected in a full network mesh to provide maximum redundancy and scalability. Internally, our network operates at 2 Gb/sec.
We maintain direct connectivity with tw telecom, Level(3), Internap and Comcast. Through these providers we maintain local peering in Denver to the following 10 networks:- Level(3) x2, tw telecom, Qwest, AT&T, Sprint, UUNET / Verizon Business, Savvis, XO, Global Crossing and Comcast.
All critical network infrastructure is monitored on 60 second intervals, both internally and externally to our network. Any potential issues with our network infrastructure are immediately escalated to company management.
