Question: Where in the regional US is your data center facility located and what is the susceptibility to earthquake, high lightning, severe weather, flooding and other natural hazards?

Answer: Tellurian Networks' data center is located in Northwestern NJ. No recorded earthquakes, high lightning, severe weather, flooding or other natural hazards are present in this area. Occasional snow storms and heavy rain do not affect operations.


Q: What is the local proximity of the data center facility to any airports, railroads, interstates, urban and local hazards?

A: There are no local hazards near the Tellurian Networks' data center. Our data center is situated in the downtown historic district of a small town with a population of 8,000 people. There are no railroads, pipelines, airports, interstates or other hazard areas in the vicinity.


Q: What is the configuration of the Local Power Grid of the local energy provider?

A: The power system feeding Tellurian Networks' data center is fed by both the Mid-Atlantic grid as well as the Niagara grid. Tellurian Networks did not lose power when the majority of the northeast was affected by the blackout in August 2003. Tellurian also has a backup generator with over two weeks of fuel on-site.


Q: Is the data center facility designed as a dedicated standalone data center with raised floors, adequate power/UPS/cooling/grounding/lighting/space?

A: The data center facility was designed and built as a concrete and steel structure during 1999-2000. Raised floors are not used since they were traditionally used for mainframes which required cooling air from the bottom with exhaust at the top. Today, raised floors are usually an excuse to have poor wire management and create more of a hidden wiring mess than to fulfill a practical need. All wiring within Tellurian Networks data center is neatly conveyed overhead. Tellurian Networks has an N+1 UPS system with two static transfer switches in series - either UPS can fail and all power will be transferred instantly without interruption. Both UPS units are online at all times so utility or generator power is used simply to charge the batteries. All batteries are tested on a set schedule and replaced every three years. The A/C cooling units are all independent and completely redundant. N+2 redundancy is built into the A/C cooling system design and no A/C units are reliant on a single chiller tower or Glycol circulation system. All systems are grounded following NEBS and/or NEC code where applicable. The lighting in the data center is via overhead fluorescent T8 lights which are energy efficient and provide excellent work lighting. Tellurian Networks built the data center facility with plans to expand to the second floor when needed and the floors have been designed to support the weight loads of a datacenter. Tellurian Networks can triple the current size of the data center within 90 days in the same building when the need arises.


Q: Based on TIA standards, which tier does this facility rate (1-4)?

A: According to Tellurian Networks' understanding of the draft TIA-942 standard, Tellurian Networks' datacenter is between a tier 3 and tier 4 facility. Tellurian has dual power distribution paths and N+1 redundancy on all UPS systems, uses dual power supplies for all equipment, but does not have independent dual N+1 UPS units which is required for tier 4 classification. Tellurian has experienced 100% power uptime since our power system installation in 2002 including our scheduled UPS battery replacement, weekly UPS testing, and weekly generator and ATS testing. Tellurian utilizes hot and cold aisles for optimal cooling. Since the TIA standards document is still under construction, this answer may change based on the final TIA 942 standard.


Q: What type of physical access security system is at the facility such as parking, outer doors, etc.?

A: Parking is open to the public. Tellurian Networks shares the parking lot with Sprint's local central office and tandem for northwestern New Jersey. Outer doors are all controlled via proximity card and all access into and out of the data center is logged and recorded. All users entering the datacenter must provide three identiry tokens - something they are (fingerprint), something they have (ID card), and something they know (PIN code) to gain access.


Q: What type of fire suppression system is used in the data center facility?

A: Tellurian Networks' data center is protected with Cease-Fire self-contained FE227 units which work mechanically and independently without the need for electricity (which is often turned off via EPO in the event of a fire). The FE227 units also contain a dry chemical which is more effective than gas or water and does not dissipate like gas when a door is opened by the fire department. The foam is non-caustic and provides for easy clean up. FE227 is a trademark of DuPont and is chemically similar to Great Lakes Chemical's FM200.


Q: What type of UPS system is used in the data center facility?

A: Dual MGE Comet 150 Units with 45 minutes of runtime per UPS. Batteries were replaced 10/04. All batteries are scheduled to be replaced again 10/07.


Q: Do you have generator backup power?

A: Yes. Tellurian Networks has a dedicated 150KVA GenSet back-up generator which is exercised for 30 minutes every Tuesday afternoon at 1:00 PM. An adequate supply of fuel is kept on-site to run the entire data center facility on generator power for over two weeks. Additional fuel can be delivered at any time by Tellurian Networks' contracted fuel vendors.


Q: What type of automatic environmental Monitoring is in place such as temperature, humidity and/or flood?

A: Tellurian Networks monitors the inlet and outlet temperature of every A/C unit as well as the power supply temperatures of all routers, switches and server cabinets/racks. Humidity is monitored in the basement and at two points in the data center. There are flood detectors in the basement with solenoid water supply cutoffs to prevent accidental basement flooding due to any plumbing malfunction.


Q: What type of cooling system is in use and is there redundancy?

A: Tellurian Networks' data center uses unitized 5 ton split systems with roof mounted condensing units. By the Spring of 2005, an additional 20 tons of cooling will be added by the use of floor mounted 10 ton units. We insist on N+2 redundancy built for our cooling systems.


Q: Is the control center/operator room within the data center facility or in the same proximity?

A: The NOC (Network Operations Center) is on the second floor of the Tellurian Networks data center.


Q: Is there adequate spacing for heat dissipation in the server cabinets/racks?

A: Yes. Tellurian Networks follows current best practices with a hot row and a cool row since most rack mount servers provide for cooling with a front inlet and rear exhaust.


Q: Is the facility under video surveillance? If yes, what form of video recording and archiving is performed in the server and operations centers?

A: Yes. Tellurian Networks uses 24/7 video surveillance with infinite archiving for the data center. The NOC is not under video surveillance.


Q: How often is maintenance performed on the facility?

A: UPS units perform a self test weekly. The back-up generator is tested weekly. The fire suppression system is not tested, but monitored monthly via visual system health indicators. The access control and auditing system is tested every day since logs are watched and the access is used daily by Tellurian Networks' staff.


Q: Are the power cables separated from the copper data cables?

A: Yes. Power runs are via redundant A & B overhead AC bus ways with dual taps for every two cabinets/racks (giving each cabinet/rack an A and B power feed) while copper data cabling is run overhead on a different plane via cable trays.


Q: Is the fiber cabling under floor or overhead?

A: Overhead.


Q: What is the general cabling layout/configuration in use?

A: Compliant with TIA568B with 24 ports per rack.


Q: What is the electrical grounding scheme for the data center?

A: Compliant with NEC99 code


Q: Are mirrored sites available?

A: Yes. Mirrored sites are available


Q: Do you own this data center or are you sub-contracting/sub-letting space or hosting services provided?

A: This data center is owned by the principal of Tellurian Networks.
