When selecting a data center it is important to understand how the design aspects of this can be used to benefit your organization. The Data Center is a Class A enterprise level data center that features high availability in one of the safest locations worldwide. Features of the Data Center
Data Center Architectural Design Benefits The outside of the Data Center naturally blends in with the surrounding buildings in the office complex. It has no distinguishing feature that would identify it as an Enterprise Data Center. Once you have entered the Data Center you will begin to see the major differences between a standard office building and a secured enterprise data center. Cameras record all visitors 24x7 and the videos are archived for 45 days. Secured areas inside the data center are protected by key cards and biometric hand scanners.
The Network Operation Center Security and monitoring of the data center takes place in the Network Operation Center. From this location, data center engineers monitor security, cooling, power, and network subsystems.
The Underground Bunker The underground design of the Data Center is for additional safety. A 400-ton coolant system in the rear of the data center provides enterprise level cooling and fresh air distribution throughout the data center.
Entry into to data center is protected by a "Man Trap" that requires key card and biometric hand scans for entry. The Man Trap is protected by bullet proof glass and monitored with security cameras.
There are 2-foot cast concrete walls that surround the data center. These walls are built with dual reinforced rebar and a rubber membrane to protect it from water sources. Utilizing specifications from the Department of Energy, this data center meets requirements of highest standards and compliance. It is designed to withstand F4 tornadoes and wind speeds of up to 200 Miles per Hour. Since the data center is built securely underground, a special design was used for the ground level. The top floor of the data center has the ability to collapse inwards without damaging the underground data center.
In the event of a F4 Tornado, the upper story of the building is designed to collapse. If that does not happen, the energy will blow out the building including the internal walls that are the support structure for the top level.
In order to protect the underground area from the collapse of the ground floor level, the ceiling of the data center is a concrete court deck that features layers of rubber and fleet. The Data Center is a true underground bunker protecting your managed hosting and is considered one of the Top 10 safest data center locations worldwide.
Data Center Cooling Cooling inside a data center is one of the most important aspects of maintaining reliable managed hosting servers. Maintaining a 70 degree or less temperature inside the data center allows servers to run cooler and perform faster at higher availability. Specifically, cooler temperatures reduce the risk of overheating and hardware failure.
Raised floors have traditionally been used in data center rooms for cable management, but they reduce air flow making it harder to maintain consistent cooling. This data center was built without "raised" floors and the cabling is neatly run overhead. With a ceiling almost 15 feet high, large ducts provide direct cool air from above the racks of servers inside the data center.
The aisles of the data center are designed with optimal air flow in mind as well. Each aisle is hot or cold in an alternating pattern according to the direction the servers are racked. Using this alternating scheme and hot and cold aisles, cold air from the cold aisle is vented through the front of the server and exited via the rear of the server to the hot aisle. Warm air from the hot aisle is pulled back into the cooling system to be circulated. This design allows your server to enjoy a cool 70 degrees 24 hours a day, 7 days a week!
The Data Center Power By developing special relationship with the public utility company we were able to secure a reliable power source capable of simultaneously powering up to 25,000 servers. The data center was designed with N+1 power redundancy, which means not only all the power subsystems have automatic failover, but a 3rd unit is kept onsite as a cold spare.
The Data Center utilizes a special cabinet design built for enterprise level service. Standard rack units are 40U in size, but the additional need for cooling and spacing resulted in custom built 45U cabinets. Two 20AMP circuits are provisioned to each cabinet, each coming from a divergent power source. On the end of the every aisle you notice these strips terminate inside of the overall breaker box. Each one of these power strips are fed by an individual breaker, each one of these breakers is on a different bus on either end of the row.
Cabling, Network, Cabinets The Data Center network provides 100MB (Mega Bit) service to each of our managed dedicated servers. This 100MB connection is directly connected to a full GIGABIT core network. Cabling, fiber optics, and power are all run overhead, utilizing best practices in a telecom system data center. Every room in the Data Center is fed by to unique transformers which are also part of a redundant power supply chain.
The Core Network Access to this room his prohibited to only advanced engineers. Fiber optics enter this room to feed the Cisco 12008 GSR router that powers the network. This room maintains the same 70 degree temperature and ultra redundant cooling and power units. Keycarded caged areas provide additional Multi Level security; allowing the equipment to be separated securely on a vendor by vendor basis.
The network is fed by dark fiber directly to Level 3 in Des Moines, Iowa. From Des Moines, Level 3 provides us a virtual E-WAN service to the Equinix building in Chicago. This virtual E-WAN service allows direct connectivity to our bandwidth provider Hurricane Electric. Powered only by the top transit and IP providers, The Data Center is able to provide low latency worldwide.
The network is also fully redundant, featuring divergent paths that never exceed over 50% network utilization to the internet. Divergent paths include dark fiber, OC-48 Sonet Connections, and multiple high speed connections to different providers.
The Power Room Located in Room 3 of the data center are the major power systems that power the data center. Inside this room Dual UPS units act as backup power in the event of a primary failure. These units also have the N+1 method applied with a cold stand-by available in the event of failure. You notice over head that even this power room has air protection or air conditioning. For the power room, we even have dual, air conditioning systems. UPS inside the data center is built to maintain up to 120 minutes of supported power. UPS units are automatically configured to switch over to the diesel generators if more time is needed. By utilizing the N+1 on every component of the data center we are able to offer a financially backed 100% uptime guarantee. This data center has been rated to have less than a 1% chance of complete power failure in a 20 Year period.
Diesel Generators Diesel generators make up the third major power component of the data center. They provide an alternative method that can produce power in the event of loss of power from the utility company. The Data Center is equipped with 2 750 KVA diesel generators that have the ability to be up and running in less than 15 seconds. Contracts with 4 local fuel companies allow for an unlimited amount of fuel to run these generators, indefinitely if needed. 1000 Gallons of diesel fuel is maintained inside the generators. |
