| The Network |
Tier-1 Premium Bandwidth
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 feature direct connectivity with MCI/UUnet, Savvis/Cable &
Wireless, and NTT/Verio. Our aggregate connectivity reaches an astounding
3,500+ networks just a single network away from our uplinks.
SBC Diverse Path OC-48 Fiber:
Fiber connectivity to our facility is supplied by an SBC
OC-48 diverse path fiber optic sonet ring. Featuring level 7 path
diversity our sonet ring has multiple entry points into our 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. Our optical equipment
is capable of supporting multiple OC-192 connections.
Cisco GSR 12000 Border Routers
Our network connectivity begins at our border layer which connects
directly to our Tier 1 service providers as well as our network
core. Our 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
Our 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 we utilize Hewlett-Packard Procurve switches
to 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
Our 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 our transfer switch
junction which also connects to our power generation facilities.
Our 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 our servers.
Liebert Precision power distribution units handle final power
transformation and distribution to racks.
Cummins Generator
Generator backup services are provided to our 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. |
