- Entrance requires badge or security entry
- Building strategically located outside of severe weather and seismic zones
- Building is rated to withstand hurricane force winds
- Ballistics-proof walls, doors, and windows
- 24-hour physical security monitors all cameras, door positions, and badge access areas
- Redundant off-site monitoring of all security systems
- Camera on each doorway
- Double man trap forces double verification and provides extra secure data center entry
- Door entrance to data center requires a badge to get in and a badge to get out
General Data Center Information
- 24 inch raised floor provides conditioned air from below to push hot air up for more efficient and effective cooling of computer equipment
- Hot air rises away, keeping customer equipment cool
- Sensor-driven cameras watching every door, aisle, cage, and cabinet, NOC, NODE, and other secure support rooms
- Steel structural supports and concrete walls
- Hurricane wind rated roof
- Additional water and weather resistance and membrane roof for further waterproofing
- Leak detection system
- Grounding connections on all posts, cages, and cabinets
Lobby Information
- Ballistics-proof walls, doors, and windows
- 24-hour physical security monitors all cameras, door positions, and badge access areas
- Redundant off-site monitoring of all security systems
- Camera on each doorway
- Double man trap
- Forces double verification and provides extra secure data center entry
- Door entrance to data center requires a badge to get in and a badge to get out
- Biometric hand scanner verifies unique hand geometry image and a heat signature before allowing entry into data center
Cage/Cabinet Information
- Locks are impossible to “pick” because they require unique laser-etched keys with magnetic signatures
- Keys can only be ordered by two people in the company
- Strong sheet metal cages. Can’t get a hand or foot hold (unscalable).
Electrical
- All electrical supply is configured in a 2N+1 model
- Redundant utility feeds and transformers
- Redundant main switch panels, each able to take full data center load and automated to fail over instantly if one shuts down to avoid downtime
- Each switch panel feeds into redundant Uninterruptible Power Supplies (UPSs) (4-500 kVA Powerware active units with 2 add’l. in reserve)
- Each UPS feeds through redundant cables into redundant Power Distribution Units (PDUs) (8-Powerware 150 kVA)
- Each PDU distributes power to power strips to each rack
- Each customer power strip is supplied by Redundant PDUs with automatic transfer to active power supply
- Cameras monitor room and alarm with motion
- 2 Megawatt diesel generator (1-Catepillar), regularly tested, for added protection
- Indefinite run time with refueling. Currently, over one week of continuous operation without refueling with current load. Locked within a sound-attenuated enclosure behind locked security fences and monitored by cameras. Critical functions are remotely monitored within data center. HVAC
- 2N+1 configuration. Two complete and separate air conditioning systems each fully capable of maintaining temperature, each with an additional CRAC unit
- Computer Room Air Conditioning (CRAC) units (14-DataAir 30-ton) are positioned around the data center.
- Filter the air to remove dust and lint
- Humidity the air to a finite set point to reduce static electricity
- Maintain temperature to within one degree
- Utilize a water/glycol mix from outside water towers for efficient cooling year around (2-Evapco cooling towers)
- Moisture containment basins and sensors ensure no moisture gets in the data center
- Separate and further redundant cooling systems for critical support areas (NOC, NODE, MIS, Security) (Liebert & Mitsubishi split systems, each < 1 ton)
Mechanical Room
- Cooling system pumps (3-60 Hp Bell & Gossett) in a 3N configuration with variable speed drives for reliable and finite cooling control
- Adjustments are controlled through a building automation system
- 10,000 gallon water tank onsite to maintain cooling systems through utility water system failures
Building Management Systems
- Prowatch building management system with on-site monitoring and control of all HVAC and cooling towers, as well as other mechanical systems.
Security Cameras
- Cameras digitally record all movement in and around the data center
- 7 pan-tilt-zoom cameras watch all perimeter areas
- Separate cameras focused on all exterior doorways
- Ademco digital controllers and recorders
- Seperate camera controller
- ProWatch video GUI, mulitple moniters
Access Control
- Biometric hand scanner verifies unique hand geometry image and a heat signature before allowing entry into data center
- Card access control throughout space
