Aliyance
houses all of its clients' strategic Internet development projects
and managed servers at AT&T's premier Network Operations
Center (NOC) located near Seattle, Washington. Our core server
platform is comprised of Dell & Compaq high capacity rack-mount
servers, typically with dual CPU and RAID-5 configurations.
We utilize Cisco routers, Nokia Checkpoint Firewalls, and APC
MasterSwitch remote reboot controllers. Our network of servers
are housed in contiguous 72U racks, and share a 100 Mbps Aliyance
circuit to the Internet.
The
Seattle AT&T Internet Data Center utilized by Aliyance
offers businesses Internet access capacity of 4.8 Gigabits
(dual-OC48 service) on the AT&T IP Network. Network access
is redundant with path-diverse entrances and exits. Dual access
routers connect the Internet Data Center to the AT&T IP
backbone.
Security is provided 24 X 7 and includes closed-circuit monitors,
secure-card key access, biometric scanners, man traps and
alarmed doors. Guards maintain access to the loading dock
and security personnel also monitor each center. Building
and environmental alarms are monitored locally in each of
the centers by a 24 X 7 maintenance staff and remotely by
the AT&T Network Operations Center in San Diego, CA.
Each center has dual Uninterrupted Power Supply (UPS), with
multiple modules synchronized to work in unison or independently.
UPS systems receive power from commercial power feeders and
standby generators and are designed to support the full load
at 90 Watt per square foot for 15 minutes via its "external"
battery plant.
In case of a commercial power failure, multiple standby generators
are available to provide power to the center within one minute
of a commercial power outage. The one-minute gap is covered
by the UPS battery system to ensure no impact on your equipment
is experienced. During an extended commercial power outage,
the diesel generators provide power using the fuel stored
on site. Fuel suppliers are on standby to provide additional
service.
Fire suppression in the centers is achieved through pre-action
dry pipe systems and state-of-the-art VESDA (air sampling)
smoke detection and alarm systems. VESDA systems are 100 times
more sensitive than conventional fire detection systems. Detectors
are grouped into different zones. When one or more detectors
detect smoke, the fire alarm panel opens the deluge valve
to fill the sprinkler piping with water. In case of an actual
fire, the seal on the sprinkler heads will melt and discharge
water on the affected area. Water will not be discharged in
unaffected areas.
Chiller plants and multiple CRAC units provide air conditioning.
The CRAC units are strategically located to deliver lower
temperature conditioned air to maintain a room temperature
of 72°F.
AT&T Business has designed and built reliability into
the network infrastructure of each of the Internet Data Centers
through the use of proven network components, backup or failover
hardware, and configurations engineered to provide no single
point of failure. Each Internet Data Center utilizes two or
more Cisco 7513 or Cisco 12000 Gigabit routers to transmit
and receive data over high-speed connections that leave the
facility through separate exits and travel physically diverse
paths to multiple backbone nodes.
AT&T Business provisions and maintains all network connections
from the Internet Data Centers to the AT&T Global IP Network.
