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
  gazduire datacenter
OC-48 Flashwave 4500
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
Cisco GSR 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.


Facility General Environment
Datacenter Interior

Our 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 our facility external walls are concrete poured to a height of twenty feet.

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.

We are a fully managed facility, as such technical staff includes level 3 technicians on site 24 hours per day, allowing incident response times to be kept to a minimum and system integrity retained with utmost urgency. Our average support request phone call is answered within 20 seconds, with an average electronic support response time of 10 minutes.
