There are presently 40 servers (Configuration
Details) in the AJL Hosting,
Inc. Web Farm. These servers are high end Linux and Windows Servers. Our
servers are currently running at 99.9% up time. Each
hosted account resides on one of these servers. Note: All DNS /
Mail / Control Panel servers run FreeBSD (UNIX) or RedHat (Linux)
and Apache (Web server). We also support Windows 2000/2003 server
along with Microsoft's .Net platform.
Servers
All AJL Hosting, Inc. Web servers are custom-built industrial
machines designed for a 24/7 Web serving environment. All of our
servers are equipped with dual-redundant, 400-watt power supplies,
hot swap drives and force-filtered cooling systems. In addition,
our NOC is equipped with an inventory of identically configured,
burned-in standby servers.
Force Filtered Cooling
All of our servers are equipped with a positive-pressure filtered-air
system. Four large fans pull filtered air into each server's protective
case, and the components within are cooled by fans that circulate
this purified air. This constant introduction of clean air into
the case creates a positive pressure environment ensuring that
dust and particles remain outside the server.
Redundant Hot Swap Power Supplies
Each server employs dual-redundant hot swap power supplies. If
a power supply were to fail, the server would continue running
with power from the alternate supply. Meanwhile, alarms would alert
a technician, who would quickly restore redundancy. In the meantime,
servers and client sites would experience no downtime.
Standby Servers
We keep spare servers online of all CPU configurations. If a
server were to experience a hardware failure, we would turn a key,
grab the handle on the drive, pull it out and insert it into an
identical standby CPU. We would then reboot the second machine,
and the server would be up and running again in a matter of minutes.
