Our Network

Video Integration's Network

Dual OC3 (310 Mbps) Connections
Our Network is connected to redundant OC-3 Backbones via UUNet and Cable & Wireless. Redundancy is provided using BGP based routing. BGP allows for carrier independent routing; so if one carrier goes down, BGP routing automatically moves the traffic to the carrier that is up.

Dedicated Connection
Some web providers operate an additional dial-up Internet service which slows down their connection to the Internet. We are not Internet Access providers - our scalable bandwidth lines are entirely dedicated to web hosting.

Machine Uptime Monitor
We have programs that ping your server every minute to make sure that the box is accessible from within our network as well as from outside our network. If the server cannot be pinged, the script will send you an e-mail and page our system engineers immediately. That way, you are always informed about the performance of your server and our network.

Web Server Monitor
One of our tools monitors the Apache web server on a one minute interval to ensure that it is up and serving pages. Every minute, we request a page from the http daemon. If it does not respond, our script will flag it and test it next time through. After 3 attempts the tool executes a reload on the http daemon. Then a minute later it will request a page again. If there is still no response, after one more attempt, a page is sent to our support to manually look into the situation. This script works to make sure that your server is serving pages 24/7.

Memory Monitor
This monitoring tool will make sure that no process takes up more than a certain percentage of your machines available memory. If a process consumes more than the maximum allotment, it will be temporarily killed off and the situation will be reported to our NOC staff.

Port Monitor
We actively monitor all commonly used ports, not only to make sure that they are open, but to verify that they are actually passing data. The script does this by asking for data. if the port does not respond, it will be restarted by the monitoring tool.

Automated Security
Video Integrations provides a full range of security services to ensure the safety and integrity of mission-critical data. As more businesses harness the power of the web, reliable and secure public communication is an ever-increasing need.

Firewalls
A firewall is a security device that secures the server from possible attacks. It is placed between the server and the Internet to moderate and document requests for data access according to a predefined set of security policies. Every Video Integrations server comes equipped with a firewall, they are the finest Cisco Systems firewalls and are managed by Video Integrations security engineers. In addition to the individual server firewalls, our entire network is secured through a circuit level firewall, providing one more level of security for mission-critical data.

Automated Security Monitoring
We proactively monitor system processes on each server as well as across our entire network. These monitoring programs are designed to halt and report all intrusions to the system and provide our customers with the peace of mind they need to conduct secure business transactions from your servers.

Network Operations Center (NOC) Features

Backbone Internet Connectivity

Redundancy is provided using BGP based routing. BGP allows for carrier independent routing; so if one carrier goes down, BGP routing automatically moves the traffic to the carrier that is up.

Premises

Physical facility is housed in a poured concrete sealed underground room, making it resistant to natural disasters.

State of the art security monitoring system including intelligent card access and 24x7 video surveillance.

Raised floors that push air up through force filtered-air up through server cabinets.

Power Redundancy

The facility has a three stage monitored power redundancy system.

Nashville Electric Service Power Grid.

EMG 100 KVA UPS system.

300 KVA Kohler diesel generator (with 72 hour fuel supply that can be refueled).

In the event of a NES power outage the EMG UPS will provide power to the room for up to 90 minutes. Within 7 seconds of a failure the Kohler diesel generator will be at full operating capacity with a run time of 3 days, that will be refueled once 50% is used.

Diverse Communications loops

The facility has two diverse Sonnet Rings for communications backbones (Through Adelphia and BellSouth). If a fiber cut occurs anywhere, the traffic is automatically re-routed.

Two diverse fiber paths exiting the building at opposite ends. This protects against outages due to a fiber cut on one circuit.

Facility Equipment


The facility backbone consists of Foundry Gigabit switches, HP ProCurve switches and Cisco routers and external firewall.

Full Tape Backup System on network with daily updated backups.

Our Network is connected to redundant OC-3 Backbone connections through UUNet and Cable & Wireless.

Hardware

Intel & AMD Servers
Your site will be hosted on one of our continuously monitored, high performance servers. We only use the highest quality parts and test all servers before we put an clients on them.

Force-Filtered Cooling
All the drives, motherboards, and power supplies of our computers are in cases with a positive pressure filtered air environment. Two large fans pull air into the protective case through filters, and the components within are cooled by fans which circulate this purified air. The constant introduction of clean air into the case creates a positive pressure environment, ensuring that dust and particulates are swept out and never in. Raised floors that push air up through force filtered-air up through server cabinets.

Standby Servers
We keep spares on-line of all CPU configurations. If your server were to experience a hardware failure we would literally turn a key, grab the handle on your drive, pull it out, and insert it into an identical standby CPU. We would reboot the second machine and your site would be up and running again in a matter of minutes.

Hot Swap Drives
The drives and drive bays of our servers are all constructed from high-grade aluminum, and rest in a Shock Mounted Drive Cage, which adds to the durability of the hardware. The drives are hot swappable, which means that if any part of the server were to fail we could simply insert your drive into an identical standby machine. This entire process takes under 5 minutes. In addition, we backup our servers nightly. If a drive has a problem, all we have to do is copy your backup (never more than 24 hours old) onto a standby machine which is already on-line. Your site is up and running within a matter of minutes.

Redundant Hot Swap Power Supplies
Each server has dual redundant hot swap power supplies. If one of these power supplies were to fail, the server would not go down because each power supply is capable of running the server by itself, indefinitely. Meanwhile, alarms would alert our technicians to the problem; they would restore redundancy by swapping out the failed unit with one of our spares and then service the old unit. During all this, your site would never be down.
