TierPoint Oklahoma City DC2 Facility Attributes
Built for Strength, Security, Connectivity
Our new DC2 facility (opening Fall 2015) is a carrier-class, carrier-neutral facility with enhanced construction
features designed to battle the elements including enhanced resistance to wind and water with a reinforced foundation to withstand moderate seismic forces. Built on our 15 acre data center campus, the
facility is fortified to help ensure the safety and security of your data and systems, with tilt-up concrete
panels surrounding each section of the building creating multiple layers of physical security.
Building Construction and Floorplan
The new TierPoint Oklahoma City data center (DC2) is a Tier III facility that totals 69,867 sq ft of space,
including 21,118 sq ft of office space (2 floors), 34,219 sq ft of raised floor (30”) and 14,530 sq ft of
support space.
The facility is constructed of tilt-up concrete panels surrounding each section of the building (office space,
data center, and support space) creating multiple layers of physical security. The structural steel framing
and load bearing concrete shear walls for the data center area of the facility were designed to withstand
moderate seismic forces in accordance with the International Building Code, which is approximately
a magnitude 5 earthquake. It was also designed to resist the wind pressures calculated in accordance
with the International Building Code for 165 mph wind speeds. The enhanced F scale lists an EF3 tornado
as having wind speeds ranging from 136 mph to 165 mph. The structural steel framing and load bearing
concrete shear walls for the data center area of the building will adequately resist the wind pressures
associated with the range of wind speeds up to an EF4 tornado.
The roof is designed to not only handle significant wind resistance, but more importantly to resist any
penetration of moisture. The roofing system is constructed of the following separate elements to protect
against moisture:
1 Structural Steel Framing – Structural steel beams, bar joists trusses and roof decking create the
base for the attachment of all other elements of the overall roofing system.
2 Dens Deck Substrate – 5/8” thick fiberglass reinforced sheathing board that is mechanically attached
to the structural steel framing.

3 Vapor Barrier Membrane – This membrane consists of single ply of modified Bitumen sheeting
which will prevent the transmission of moisture vapor into or out of the building (depending on the
season) and will allow specific control of the level of humidity within the Data Center. This membrane
is applied with an adhesive fastening versus mechanical fastening to ensure that the vapor barrier
membrane is not compromised.
4 Rigid Insulation Boards – A five inch thick layer of rigid insulation boards is installed over the vapor
barrier membrane using adhesive that insures there are no penetrations in the vapor barrier.The insulation
boards keep the interior of the space at a controlled temperature, protecting against the hot and cold
extremes of the outside air temperature.
5 Dens Deck Substrate – 1/4” thick fiberglass reinforced sheathing board is adhered to the rigid
insulation, providing a protective surface over the insulation layer as well as a solid surface for the
adhering of the roofing membranes above.
6 Base and Top Membranes – Two separate plies of roofing membranes (prefabricated, reinforced,
homogenous styrene-butadiene-styrene (SBS) block copolymer modified asphalt membranes) are
applied over the previously installed roofing elements. Both reinforced membranes will be saturated
and coated on each side with an SBS modified bitumen blend. This adhering method insures that there
are no penetrations in the vapor barrier and the roofing membrane will shed water to the outside
perimeter and away from the conditioned envelope of the building.
The raised flooring is manufactured by Tate, sits at a height of 30 inches and utilizes a stringer system with
concrete filled panels designed to support a standard load of up to 2,500 pounds. Additional weight can
be supported with tile bracing. Under floor access is restricted to TierPoint Operations and Engineering
personnel and approved escorted vendors.
The data center space is 12 feet from top of raised floor to ceiling height. Customer cages may be
installed to restrict access from slab to roof if necessary.
The facility has two staging rooms approximately 230 sq ft each that can be reserved for unpacking and
staging of equipment prior to installation.
Electrical Systems
The building is fed from two different substations through two different entry points with a total capacity
of 5,000kVA (redundant 2,500kVA transformers at each entry). Other features include:
• A common generator bus with N+1 redundancy powered by (4) Cummins two megawatt standby
diesel generators totaling 8,000kW total (6,000kW of capacity with redundancy)
• Each generator is supplied from an internal 300 gallon day tank which is fed from a below ground
exterior 30,000 gallon tank.
• The generators are exercised weekly for 30 minutes with no load. They are tested quarterly with
current facility load and are tested annually with an external load bank for 4 hours each. As part
of this process the generators are operated to the maximum load.
The UPS systems are installed in 500kW increment pairs up to 6,000kW assuming a full 1+1 redundant
design supporting a 3,000kW IT load. Power feeds into tenant space are delivered by independent A&B
power systems each with dedicated switch gear, UPS plant, RPPs and in rack PDUs.

Cooling Systems
The data center is designed to support an average of 125 watts per square foot utilizing three 450 ton
chillers and multiple Liebert CRAH units in an N+1 configuration. It is designed to operate at 100%
cooling with 20% of the systems offline. Traditional hot and cold isle configurations are in use in all tenant
spaces. Temperature sensors are integrated into all CRAH units, supply and return. A second temperature
system is installed in all cold and hot isles every 6th cabinet. The temperature readings are integrated into
our building automation system and Struxureware - Data Center Operations by Schneider Electric.
Data Connectivity
All native fiber to the facility utilizes two separate building entrances through (8) four inch ducts containing
multiple one inch innerducts. Current fiber providers include AT&T, Cox Communications,Verizon, Chickasaw,
and Cogent. TierPoint DC2 is also connected to via multiple private fiber paths to TierPoint DC1 for
connectivity and redundancy.
Physical Security
Both TierPoint DC1 and DC2 are located within TierPoint’s privately owned 15 acre campus, surrounded
by 10 foot fencing with barbed wire topping. A double electronic gate is located at the only entrance to
campus and is tied to the access control system. The entrance to the facility is protected with a grass
berm and concrete reinforced bollards. Other security features include:
• The parking lot and all surrounding areas of the building are illuminated dusk to dawn
• All motion in and around the building will be monitored by our on-site security personnel 24 hours
a day, 7 days a week, 365 days a year and recorded through our dedicated DVR camera system.
• Access control is located on all entrance doors for the building as well as all entrance/exit doors for
the data center space and all support areas.
• A single mantrap is present to gain access to the data center hallway intersecting the data center
space. All doors entering tenant areas are also tied to our access control system.
• Approved customers and vendors must initially register onsite in TierPoint’s proprietary biometric
authentication system. Once registered, anyone visiting the facility must check in with Security and
authenticate through our proprietary biometric authentication system which includes signature
and photo capture (with time stamp).
• Interior and exterior cameras are utilized extensively throughout the facility. All motion is recorded
24x7x365 utilizing a DVR system with dedicated RAID5 storage. Security and support personnel
constantly monitor the cameras.

Fire Suppression
The data center and all support spaces are protected with a pre-action dual interlock dry pipe system that
is pressurized with nitrogen. The purpose of this feature is two-fold: first to monitor piping for leaks and
second to hold water from system piping in the event of inadvertent detector operation.
Detectors are located under the raised floor, within the data center space, and in the return plenum
above the ceiling. The advantage of using pre-action fire sprinkler systems is that dual action is required
for water release. This feature provides an added level of protection against inadvertent discharge.
All aspects of the fire suppression system are inspected and maintained annually.
Water Detection
Water detection rope and sensors surround the entire exterior of the data center, chilled water piping,
plumbing fixtures (bathrooms, drains, faucets), and fire suppression system. The system is monitored
24 by 7 with remote alerting.
