Power & Cooling
Commercial Power
- Dedicated underground 12,000 V feed from a newer Rocky Mountain Power substation next to downtown library. Buried under mass-transit system to reduce construction risk.
- Building load handled by 2,500 KVA (2 Megawatt) Transformer over sized for extra protection and durability. Transformer is secured externally from building.
Generator
- Two 500 KW Cummins DFED Gensets with a 18.8 Liter turbo diesel/Aftercooled KTA-19 engine. Two currently handling facility load and providing A+B redundancy.
- Low fuel consumption and rigorous testing schedule allows long term power generation for facility's needs.
Power Infrastructure
- Cummins Power Generation OTPC transfer switch gear rated for 1200 Amps at 480 Volts. Detects faults in power feeds, turns on emergency power generators, verifies power condition and if all is ok, transfers facility load to the emergency power equipment.
- Cummins Power Generation BTPC series bypass isolation transfer switch gear rated for 1200 Amps at 480 Volts. The BTPC series allows power to be routed around a failed transfer switch unit.
- Three Mitsubishi 9800 AD UPS's (Uninterruptible Power Supply) 225 KVA (190 KW). Utilizing Mitsubishi IGBT technology, power efficiency improves by providing cleaner total power to customer equipment.
- Seven (7) 480 Volt/3 Phase Power Distribution Units/Transformers (PDU)
- Two (2) 208 Volt 3Phase Remote Distribution Units (RDU)
- Active monitoring of power loads and infrastructure utilization allow accurate planing of load redundancy at the client level.
- Measurements taken every 4 hours and entered into database
Fuel Tank
- Single 366 Gal double-lined fuel tank, in basement
- 25 gallon day tank, on roof
HVAC
- Liebert Deluxe System 3 CRAC (Computer Room Air Conditioner) units connected to over-sized GlyCool cooling towers via redundant dual pump system. N+1 configuration allows full proper service work without change in temperature.
- Five (5) cooling towers, 30-45 ton cooling capacity each
- Three (3) 30-ton CRAC units
- Two (2) 20-ton CRAC units
- One (1) 10-ton CRAC unit
- Two (2) 5-ton CRAC units
- Designed to N+1 redundancy
- 2 foot return air Hot Plenum in ceiling. Utilizing new thermal technologies, a fully functional hot plenum is used to improve the delta-t, which provides better heat removal efficiency.
- 10 Feet vertical workable space above raised floor.
Bandwidth
XMission uses the industry standard 95th Percentile model to bill for bandwidth. http://en.wikipedia.org/wiki/Burstable_billing This allows you to only pay for the bandwidth you use while offering the benefits of faster speed and greater throughput.
To determine your billable utilization, otherwise known as your “95th percentile rate,” XMission measures your bandwidth usage at regular intervals over a 30.5 day period. At the end of the period, XMission will discard the top 5% of your inbound and outbound bandwidth samples separately (approximately 36 hours worth of traffic). The remaining measurement becomes your 95th percentile rate.
If your 95th Percentile Rate exceeds your Committed Data Rate (CDR), XMission will post-bill you for any overages at the CDR price per Megabit.
