Network
Operations Center (NOC)
features raised
flooring. This enables a constant flow of conditioned air and
helps to maintain uniform room temperature at all times. In
addition, raised flooring reduces static and ensures a
professional, computer grade environment for our servers.
The facility is equipped with a
Raytheon fire suppression system, designed to immediately
extinguish fire and protect equipment and personnel. The
command center is controlled via automatic doors to further
secure and protect the equipment.
Finally, the NOC is located in
a secure, monitored, "class A" building with a
minimum number of approved personnel allowed access to highly
sensitive areas and equipment. A detailed record of employee
and visitor entry is maintained at all times.

Uninterruptible
Power System
|
|
To guard against local power failures, OnNet has two
industrial-grade, three phase Liebert UPS systems. These act
as back-up batteries, maintaining uninterrupted power in case
of surges or power outages. |
| In addition,
the NOC is supplied with triple power feeds from the
utility company. In the event of a power outage,
the data center is equipped with a 1500 KVA ONAN diesel
generator. The generator is tested every week.
When a power outage is detected, the generator will
start automatically within 15 seconds. With one
tank of gas in the generator, it can power 15000 servers
for 36 hours. Fuel can be added to keep the
network up and running indefinitely. |
|
Industrial-Grade Air Conditioners
OnNet's NOC has two Liebert ten-ton industrial air
conditioners, which condition our computer rooms and
operations center. Our computer room is kept at an optimal
temperature of 65 degrees fahrenheit.
Custom
Web Servers
|
OnNet uses only top of the line web servers
including IBM servers and our own custom-built
industrial machines designed. All are designed for a
24/7 web serving environment. All OnNet servers are
equipped with dual redundant 450-watt power supplies,
hot swap hard drives and
force-filtered cooling systems. In addition, our NOC
is equipped with an inventory of identically
configured, burned-in standby servers.
We use only up-to-date powerful
servers. Unlike some low-end hosting companies,
we do not use any Celeron, AMD and Cyrix chips.
We back up all servers and provide facilities so you
may backup your site as well.

All
new servers are configured with a minimum of:
Raid-5
Dual Pentium III Class Processors
1.0 Gig of RAM
SCSI Hard Drives for faster performance
Mirrored Hard Drive
Backup facilities
Red Hat Linux 7.3
|
Standby
Servers
|
We keep spare servers on-line 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.

Force
Filtered Cooling
All of OnNet's web 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 which circulate this purified air.
This constant introduction of clean air into the case creates
a positive pressure environment ensuring dust and particles
remain outside of the server.
Hot
Swap Seagate Drives
The drives and drive bays of all OnNet servers are
constructed from high-grade aluminum, and rest in shock
mounted drive cages, which adds to the durability of the
hardware. OnNet's drives proudly feature the lowest failure
rate in the industry.

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.
Connected to Three Backbones
The OnNet NOC is located literally "OnNet" with GlobalCenter
(GC), Qwest Communications and GTE through
three separate bandwidth-on-demand connections which enter the
city in our building.
GC, a Tier 1 provider
whose 13,000-mile fiber optic network and Dense Wave Division
Multiplexing (DWDM) technology provide an enormous 460
gigabytes per second (Gbps) of capacity worldwide, has an
Asynchronous Transfer Mode (ATM) fiber node located just a few
floors below the OnNet NOC.
Qwest comes into the
city with an OC-12 line and plans to upgrade their connection
to an OC-48 in the near future. They also have an ATM fiber
node floors below the OnNet NOC. Our Qwest connection enables
us to offer additional redundancy and better routes to Europe,
Latin America and Asia. With our carriers, our router has up
to 150,000 possible routes to send each packet of traffic.
Genuity, a division of
GTE, is our third Tier One Internet backbone. Genuity provides
excellent network performance as a result of their high-speed
peering arrangements with other Tier One Internet backbone
providers. The GTE global network delivers customers directly
onto the Internet via a high-speed connection to its private,
super-capacity backbone, including 17,000 miles of fiber and
OC192 capacity. It is comprised of more than 800 U.S. local
access points and approximately 1,500 international local
access points in more than 150 countries.

|
Furthermore, because of these
unique connections, OnNet does not need to link to the
Internet though an OC3 or T3 Telecom circuit. Instead,
independent cables run inside our building directly from the
NOC to all three carriers points of presence. These lines can
handle the bandwidth of a T3 or an OC3 with DWDM. Plus, they
handle several times the bandwidth of an OC3. Whatever your
bandwidth needs may be, OnNet has the scalability to meet
them.

Network
Redundancy
We use intelligent end-user routing software called Border
Gateway Protocol (BGP), between Qwest, FGC and GTE, who use
the same protocol. BGP identifies which path is the most
efficient for each data packet and then routes the packet to
its destination on the fastest path. This increases the speed
at which web pages sent from our NOC arrive at their
destination.
Studies have shown that the
most common reason for downtime is circuit failure on Tier 1
provider backbones, the major data highways. To guard against
this potential problem, we have three Tier-1 providers. If one
experiences problems, we can route traffic down the other one.
Furthermore, because we are OnNet with GlobalCenter, Qwest and
GTE, we share their digital distribution architecture, which
includes private peering network connections to major Internet
carriers such as MCI, Sprint, UUNET, EUNET, AT&T, AOL,
Best, Erols, Global Crossing, IBM Advantis and others. These
private peering arrangements allow us to exchange packets of
data with every major backbone carrier in a one-to-one
environment quickly and efficiently.
In addition, FGC has high-speed
links to eight public exchanges including both MAE East and
West and several NAPS. Through these public exchanges,
customers have the ability to reach their site, no matter from
where they are coming on the Internet.

Network
Reliability
Industry analysis reveals that 70% of downtime over ten
hours with any ISP is caused by telephone circuit failure.
Since our NOC is in the same building as Global Center, Qwest
and GTE, circuit failure is virtually eliminated because there
is no phone circuit between us and our providers. Instead,
there is a direct connection between our Cisco 7500 routers
and theirs.
Our providers also have peering
connections with other major Tier 1 providers, which allows
traffic to be switched to alternate backbones should the need
arise.
Raw
Performance Equals Low Latency/High Throughput
Too often providers operate their networks at three to four
times responsible capacity. As a result, their corresponding
transfer times reach over 300ms. Our network daily average is
27% of its capacity, with midday peak spikes reaching only 33%
capacity. Under normal conditions, clients will be carried off
our network in less than 15 - 80ms over a five minute average
at any time of day or night.
