All of our servers are co-located at a Internet Service Provider (ISP) with a data center facility in downtown Denver, USA. Data center facility have over 4,000 square feet of raised floor and another 2,500 square feet of office space to support day to day business operations and on-site staff.
Located in Denver's central business district, the building we occupy 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, ISPís diesel generator will immediate start up and begin carrying the entire data center load. Building life safety systems are backed up by two separate generators.
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 Fahrenheit 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. ISP also has local and remote environmental monitoring systems in place.
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, ISP have their own security system which consists of access control systems within their own office suite and remotely monitored video surveillance.
Fire detection within the data center is provided by an early detection alarm system monitored both within our 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.
