Network Infrastructure Overview
Our redundancy is multi-tiered with N+1 internal device elements as
well as entirely redundant chassis allowing any routing device to fail
without interrupting client data connectivity. All core routing and
switching equipment is state of the art Cisco.
Tier-1 Premium Bandwidth Providers
Our Tier-1 Providers
Providing the highest quality Internet connectivity
and performance is our top priority. Fitting with this we have exclusively
selected premium Tier-1 bandwidth providers, ensuring minimal latency
and excellent reach ability on a global basis. We are proud to feature
direct connectivity with MCI/UUnet, AT&T, and Savvis/Cable &
Wireless. Our aggregate connectivity reaches an astounding 4,500+ networks
just a single network away from our uplinks.
SBC Diverse Path OC-48 Fiber
OC-48 Flashwave 4500
Fiber connectivity to the facility is supplied by an SBC OC-48 diverse
path fiber optic sonet ring. Featuring level 7 path diversity the sonet
ring has multiple entry points into the facility as well as connectivity
directly to multiple carrier offices. There is no shared physical path
at any point in the entire sonet loop. This design allows for uninterrupted
service even in the event of a fiber cut, or other direct CO equipment
failure. The optical equipment fabric is capable of supporting multiple
OC-192 connections.
Cisco GSR 12000 Border Routers
Cisco GSR Routers
Our network connectivity begins at the border layer
which connects directly to the Tier 1 service providers as well as the
network core. This reliance on multiple devices each with internally
redundant systems ensures the highest levels of reliability. Each Cisco
GSR is capable of independently routing 60 gigabits of data at wire
rate while isolating any fault risk to each independent line card. Connections
to the core are derived independently enabling yet another layer of
redundancy and performance load balancing.
Cisco 6509 Sup720 Core Network
Cisco Sup720 Core
The fully redundant network core handles bandwidth
aggregation and routing for the entire network. Each Cisco 6509 Sup720
is capable of routing up to 400 million packets per second with a total
capacity of 720 gigabits per second each. This layer is fully redundant
with each unit possessing the ability to route the entire core in the
event of a device hardware or software failure. Core failure recovery
is a nearly instantaneous process and is fully automated by the self-healing
core elements.
Cisco 3550 Distribution Switches
Distribution To Servers
Final layer3 distribution to rack switches as
well as VLAN segmentation is handled by Cisco Catalyst 3550 distribution
switches. Each switch is capable of handling simultaneous wire rate
data traffic for every port configured ensuring optimal performance
and eliminating blocking potential to the core or individual rack switch.
At the rack layer Hewlett-Packard Procurve switches follow and further
enforce VLAN segmentation protocols from the distribution layer as well
as offer final customer network access.
Datacenter Power Systems Overview
Powerware 9315 UPS
The power systems feature extensive fault tolerance
and resilience at every layer. Incoming service is routed underground
to a dedicated on-site transformer. This system routes to a transfer
switch junction which also connects to the power generation facilities.
The primary UPS is a 300kva Powerware 9315 featuring redundant battery
cabinets and a full maintenance bypass allowing for service and upgrades
without interruption of power to the servers. Liebert Precision power
distribution units handle final power transformation and distribution
to racks.
Cummins Generator
Generator backup services are provided to the facility
by a Cummins 313kVa Diesel Generator featuring over 24 hours of autonomous
runtime before requiring refueling. Generator power is activated automatically
in the event of a grid failure by the transfer switch. The intermediate
load is capable of being handled for over an hour by the UPS, however
this is not necessary as the generator is active and up to speed within
16 seconds of a power failure.
Facility General Environment
Datacenter Interior
The facility includes over 11,000 square feet of
available space. Construction is built to surpass local building area
codes and seismic requirements. Industry standard hard floors are covered
with vinyl tile and overhead wiring systems are utilized for enhanced
cooling and a more secure cable infrastructure. Datacenter access is
strictly limited to technical staff. Electronic security systems control
datacenter access and are accompanied by a full compliment of motion
detecting security cameras which are strategically placed throughout
the entire facility. Furthermore the external walls are concrete poured
to a height of twenty feet.
Environmental Controls
Liebert 22 Ton AC Unit Environmental processing systems include redundant
Liebert Precision 22 ton up flow air conditioning units. Temperature
and humidity are precisely regulated year round to ensure optimal equipment
reliability. Each unit contains independent compressors and cooling
loops to further enhance fault tolerance and reliability. Air filtration
systems actively remove foreign particulates from circulation and cycle
the entire datacenter air supply in a matter of minutes.
