Infastructure
We
run four state-of-the-art, secure data centers monitored 24/7 by
expert network engineers to ensure maximum security and uptime
for our customers' servers. The best of breed equipment like Dell™ PowerEdge
and HP ProLiant™ Servers,
Cisco™ & Foundry™ Firewalls and Routers and premium bandwidth through a
partnership with AT&T and Cable & Wireless. Two world-class quality
Tier 1 Internet Data Centers are optimized to provide an industry-leading web,
data, and applications hosting environment. These centers are designed to stay
up and running, protected from power failure, physical intrusion and network
outages by extensive back-up power and cooling systems, multi-layered security,
and network redundancy and diversity. Our Data Centers are connected to the
Internet using the highest performing OC48/OC192 IP backbone available.
Network
Flexible,
on-demand access to network capacity of 7.2 Gigabits on an AT&T Local
Services ring that is redundant and diverse. Dual access routers
connect IDC to multiple AT&T IP backbone nodes via dual OC-48/OC-192
connections. Back-end connectivity and network services options
available include ATM, Frame Relay, private line, IP and local-switched
and circuit-switched services, with local access provided by both
AT&T and other local service providers.
Security
Security is provided
24x7 and includes guards, closed-circuit monitors, alarmed
doors with secure card-key access, biometric scanner, "man-trap" restricted
access to the data floor and options for locking equipment
enclosures (cabinets or cages). Guards maintain access to the loading dock
and access requires a card key. Security personnel also monitor
the building. Building and environmental alarms are monitored
24x7 by our staff and remotely by the Network Operations Center.
Power
Our IDCs are designed for 90W/sq ft of conditioned floor
space. Most have dual (2N) Uninterrupted Power Supply (UPS), each with multiple
modules synchronized to work in unison or independently. UPS systems receive
power from both commercial power feeders and standby generators and are designed
to support a fully loaded center for 15 minutes via its internal battery plant.
In case of a commercial power failure, banks of diesel generators in an N+1 design
(at full load) 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 equipment. During an extended commercial power outage, the diesel
generators provide power using the fuel securely stored on site. Fuel suppliers
are on standby to provide additional service.
Fire Detection & Suppresion
Smoke detection is delivered using state-of-the-art
VESDA (air sampling) smoke detection and alarm system. VESDA systems are 100
times more sensitive than conventional fire detection systems. Detectors are
grouped into zones. Fire suppression is via a pre-action dry pipe system. Once
one or more detectors sense smoke, the fire alarm panel the deluge valve
to fill the sprinkler piping with water. In case of an actual fire, the seal
on the sprinkler head will melt and discharge water on the affected area.
Cooling
The IDCs have multiple chillers and Computer Room AC
(CRAC) units to provide air conditioning to meet AT&T N+1 redundancy requirements.
The CRAC units are strategically located near the racks to deliver temperature
and humidity conditioned air to maintain a room temperature in the range of
75°F. Chilled air is distributed via 30 inch raised floor air plenum, which
provides maximum flexibility for increased power and cooling requirements.
Cable Distribution
The raised floor also houses the under-floor power and low-voltage cable
distribution system. This is an extensive network of intra-building cable and
wiring that supports both power cables as well as low voltage telco wiring
in sub-floor ladder-racking. |
