Industrial-Grade Equipment for the Ultimate In
Performance and Reliability
recognizes that down time is not an option for your web site. That's
why we invest heavily in hardware and facilities that ensure your
clients are up and running on the web 24 hours a day, seven days
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
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.
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.
guard against local power failures, We have two industrial-grade,
three phase Liebert UPS systems. These act as back-up batteries,
maintaining uninterrupted power in case of surges or power outages.
With these backup systems in place, we can keep our network up and
running indefinitely without relying on external power.
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.
web servers are custom-built industrial machines designed for a
24/7 web serving environment. All servers are
equipped with dual redundant 450-watt power supplies, hot swap Seagate
Baracuda/Cheetah drives and force-filtered cooling systems. In addition,
our NOC is equipped with an inventory of identically configured,
burned-in standby servers.
of our custom 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.
Swap Seagate Drives
drives and drive bays of all servers are constructed
from high-grade aluminum, and rest in shock mounted drive cages,
which adds to the durability of the hardware. Our
drives proudly feature the lowest failure rate in the industry.
Hot Swap Power Supplies
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.
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.
to Three Backbones
NOC located in Baltimore, Maryland is OnNet with
GlobalCenter (GC), Qwest Communications and GTE through three separate
bandwidth-on-demand connections which enter Baltimore in our building.
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
comes into Baltimore 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 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
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.
because of these unique connections, We do 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, we have the scalability
to meet them.
use intelligent end-user routing software called Border Gateway
Protocol (BGP), between Qwest, GC 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.
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, @Home,
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.
addition, GC 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.
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.
providers also have peering connections with other major Tier 1
providers, which allows traffic to be switched to alternate backbones
should the need arise.
Low Latency/High Throughput
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.
We guarantee clients will be carried off our network
in less than 80ms over a five minute average at any time of day
