The Data Center
Silicon Valley Web Hosting is located in the SAS 70 compliant Coresite Market Post Tower data center in the heart of Silicon Valley in San Jose, CA.
This Data Center offers an uncompromising level of physical security in addition to multi-stage fire suppression systems; redundant cooling units; and multiple uninterruptible power sources with fully conditioned power.
Physical security is maintained through the use of physical check stations (where ID must be presented before access is allowed to the facilities), closed circuit camera systems, and a combination access card, biometrics entry system, and traditional keylock entry. In the case of the access card and biometrics entry system, an access card is used to activate the palm scanner, and then the palm scanner is used to grant entry to the colocation floor. Once inside the colocation facilities all of our equipment is stored in our own locked suites.
Multi-level (redundant) fire suppression systems are used in the advent of a fire. A combination of dry chemicals and pre-action dry-pipe sprinkler systems are used to protect against fires. A typical response to fires can be broken down into three distinct phases:
When the first smoke detector detects smoke, it primes the dry pipe system and activates alarms at the security desk, facility floor and inside the server room. As a precaution, the system waits for a second alarm.
When the second smoke detector activates, it sounds an additional alarm and starts a 30 second count down to the release of the Heptafluorapropane. During the 30 seconds, the system can be overridden. At the end of the countdown the gas is released to stop the fire reaction.
If the fire continues past the Heptafluorapropane release, the dry-piped pre-action system will isolate the fire. The heat will open one of the high heat sprinkler heads and release the air pressure in the pipe. The pressure release opens the water valve allowing water to flow through the open sprinkler on to the fire. This system will only dispense water through the pipe of the opened sprinkler. The rest of the facility will be unaffected.
Environmental conditions are kept at a constant in the colocation facilities. A constant temperature of 68 degrees (plus or minus 2 degrees) Fahrenheit is maintained with a humidity at a constant of 45%. Multiple redundant cooling units are maintained with ample spare capacity; in the event of a cooling unit failure the environmental conditions inside the facilities will not be effected.
The power system is designed to provide fully filtered non-stop power. The power is drawn upon three sources; (1) commercial utility underground conduits; (2) a full battery backup system; and (3) diesel generators each with 1000-gallon fuel capacity and full-load capabilities. The system utilizes an AC-DC-AC conversion process to completely eliminate surges and under-power conditions. At the heart of the system is the Automatic Transfer Control Logic system (ATCL) which constantly monitors the power throughout the entire system.
In addition to the multiple sources of power, the system has the following features:
- Parallel redundant UPS modules
- Redundant primary 480V feeders
- Split switchboard with draw-out tie-breaker
- Redundant 500KVA K13 transformers
- 48V DC power plant with separate batteries and A+B bus for redundancy
- Dual-fed secondary switchboard and critical load distribution boards
- Maintenance bypass feeder with dedicated 500 KVA K13 transformer
- Dedicated 20 amp circuits with #10AWG (30 amp) wiring to rack plug strips, including dedicated neutrals feeding server racks
The Network Backbone
Our network is comprised of transit capacity drawn from Internap's Performance IP Service and Hurricane Electric's global footprint. In addition to our connectivity to these network carriers we are a member of the Any2 Peering Exchange located at One Wilshire in Los Angeles, CA.
Combined, these networks peer at all of the major Internet Exchange Points (IXPs) and Network Exchange Points (NAPs) world wide. Multiple connections to each IXP and NAP are maintained from different points on the networks so if major regional outages occur connectivity to these exchange points will not be lost.
In addition to public peering, all networks maintain an extensive set of private peers and session exchanges. Private peering arrangements allow us to exchange traffic directly with other networks; completely bypassing the public exchange points.
