FM-200 Gas System a non-toxic, non-water based fire suppression
system; and a double pre-action dry pipe sprinkler system that fills up,
but won't release water until the tip of the sprinkler is burned.

Staffing
Technical
staff will be on hand 24/7 at the Premier Data Centers, allowing you access
to your servers at all times. Each facility has approximately 30 people
on staff and there is always more than one person on site. A multi-million
dollar Management System will also be in place at each Premier Data Center,
allowing engineers to better monitor the facility, network and equipment
from a control center. In Addition, VPS Hosting is Monitoring the network
remotely utilizing special technologically advanced interfaces.
Security
Includes
24/7 security guards at the front door and on the premises; biometric
hand scan into a Man Trap for controlled entrance/exit; video cameras
throughout the facility.
Connectivity
| |
The
Premier data centers have connections to many different Internet
backbones including UUNet, Sprint, Cable and Wireless, CRL, Qwest,
Exodus, Agis and Net Axs. We also have private and direct peering
DS3's set up between our location and that of American Online and
PSI-Net. In addition, the data center operates its own DS3 to Mae
East to peer with many of the smaller Tier One providers as well
as operating another DS3 to the ATM switch located there.
By
connecting to multiple backbones, data can be distributed through
many sources. |
This architectural
design also means that we are not dependent upon any single Internet backbone.
Thus when problems occur, we are able to reroute traffic automatically,
thereby ensuring the integrity of our network and continued access for
our high-speed dedicated server clients.
Furthermore,
by routing traffic mainly across large Internet backbones instead of sending
data through meet points (commonly referred to as NAPs), the data traffic
from our network avoids these centers of high congestion. In effect, we
have created a small-scale NAP by accessing large Internet backbones through
private peering arrangements.
In fact,
large Internet providers such as UUNet and Sprint no longer trade traffic
across meet points either. They have instead setup private connections
between their backbones. However, these private interconnects have also
become full because of the amount of traffic that they exchange. Thus,
a Sprint customer trying to access a server on UUNet's network would experience
packet loss across the interconnecting DS-3. Problems have arisen because
both companies feel the other is responsible for upgrading the circuit.
Our Backbone
Provider (NTT/Verio) does not have these problems because it pays for
usage. Thus, if the UUNet connection starts experiencing packet loss,
the NTT/Verio team is responsible for upgrading the circuit. This point
also reinforces the advantage of our network architecture. Because there
are connections to the largest backbone providers, we utilize their backbones,
where there is less data congestion. In addition, though these large backbones
may have good networks, they may not provide high-speed hosting solutions
because they have poor connectivity to other large backbones.
| |
There
is over 500 Mb of bandwidth available. Presently bandwidth utilization
is 25% during peak traffic times. Therefore, our network is very
flexible. If one of the backbones we connect to experiences problems,
we can simply choose to re-route that traffic over other paths,
thereby ensuring that users receive fast access times to sites hosted
on our network.
In
addition, a Border Gate Protocol (BGP4) is in operation. BGP is
used at a provider with more than one access point to the Internet.
It helps create a truly redundant network. In fact, in an ideal
situation, a lease line failure should result in the BGP routing
session to close on the bad leased line and the router on a working
circuit should then begin to accept the additional traffic. |
In other
words, traffic from a down circuit is re-distributed across other circuits,
thereby maintaining network integrity. Providers that are multi-homed
and correctly setup can actually be more reliable than a single backbone
provider because they have multiple paths to multiple providers.
Internal
Connectivity
A provider's
local area network is not often enough being seen as a point of latency.
The two main sources of latency for a full-time Internet connection are
the user's local area network and the Internet provider's local area network.
With networks anchored by Cisco 5500 Series etherswitches and high-end
Cisco routers (like our Cisco 7513) you are ensured exceptional routing
of data packets.
This top-of-the-line
network hardware ensures that data requests get to their destination and
back out of the network as fast as possible. We use etherswitches instead
of hubs because of their speed and their security capabilities. Whereas
only one computer plugged into a hub can talk at one time, all the machines
connected to a switch can talk at the same time. This means more data
can travel through a switch and each server acts as its own node on the
network. Furthermore, since each servers is its own node on the network,
it is difficult for hackers to trace data packets with sensitive information
(i.e. passwords) to a particular physical server.
Servers on
our network do not share a single path (T3). Instead, the servers are
connected into a high-speed ethernetswitch. This switch is connected to
the core router at the data center facility. From the core router, data
is sent back to the end user across the fastest available path.
Whereas statically
routing traffic over one path creates a single point of failure, this
distributed architecture ensures that users can access data extremely
quickly and have multiple paths both into and out of our network.
Network
Monitoring
| In
addition to its multi-homed connections and high-speed backbone, each
data center has 24/7 network monitoring. Our Network Operations Center
OnLine (NOCOL) software monitors the ports on the servers to check
if they are active. This software can monitor the web port (80), the
Real Media port (7070) or any other port which our clients have designated
as a mission-critical application running |
|
. When the
designated port is unreachable, an e-mail is sent to every member of the
technical staff. The Technical engineering staff goes into immediate action
to correct the problem.
We also have
technical personnel here 24/7 monitoring the servers. Our normal technical
support hours are 8-5 Monday through Friday PST, however, the data centers
and servers are never left unattended.
