We have three fully redundant servers located in Tulsa, Oklahoma. All
servers run Microsoft’s IIS with Windows NT 4.0 on multi-processor
Pentiums. All servers are fully backed up weekly with modifications
backed up daily.
The "back-end" is powered by a multi-threaded version of
Visual FoxPro V. 5.0. program capable of handling over 500,000 data
requests per day. We interface directly to VFP without using any ODBC
drivers (ODBC is a very common, but slower, technique used to interface
data to the internet.) As requests come in, they are distributed to
the open channels for parallel processing. All data transfers are done
in memory so there is no overhead associated with hard-drive activity.
No ODBC or temporary files are needed. Our software is 4 - 6 times faster
than similar engines using Access or Visual Basic as their data back-end.
We are even faster than most SQL Server implementations using ODBC.
Our servers are located on a 10 megabit switched segment, connected
to a 100 megabit switched backbone. From there, traffic is handled by
core Cisco 7200 series routers, and passed on to the Internet backbone.
We currently have two T3 connections, one to Cable and Wireless in
Dallas and one to RMI.NET in Santa Clara. In addition, we have a 3 meg
SprintLink connection to Fort Worth. All transit links are fully redundant
via BGP.
These lines are also redundant locally and come in through separate
local loops. One through Southwestern Bell, and the other through MCI/WorldCom.
Additionally, the lines are separated into two separate phone closets
within the building.
We contract with WebZone Network Operations Center for 24-hour support
and traffic monitoring. The WebZone
is one of the Midwest's premier ISP's, a division of Denver-based RMI.NET,
Inc. (formerly Rocky Mountain Internet) and provides us with extremely
high speed, reliable and redundant internet connections for our servers.
