Implementation

From wiki @ the zen garden

This page describes, further detailed in forthcoming documents, the layout of my network which powers several websites (this one included), services, and serves as my lab and gateway to learning about a varietary of topics. These topics range from technical ones such as networking and network management to building and maintaining servers, and everything in between. Further, this network also serves as a documentation and design platform to which I may better understand these subjects and how I can best apply knowledge gained from these experiences in my chosen career path.


The contents of this page will be continuously updated as my network expands/shrinks.

Rack Implementation

Rack implementation is broken up into several sections below.

  • Summary of Devices: Provides a list of physical devices which are currently mounted in the rack
  • Power Consumption: Details on the current power draw as measured by a Kill-A-Watt device, and power routing
  • Diagram & Details: A basic diagram showing the topology of the devices installed in the rack, and a short labeled summary as to the nodes and Vlan1 interface addresses
  • Media: Additional media/photographs related to the implementation of the rack

Summary of Devices


  • 36U Rack
  • 3 Power Distribution Units (PDU's)
  • 3 Cisco Switches
  • 3 Cisco Routers
  • 6 Physical Servers (2 presently decommissioned)

Power Consumption and Design

Media


Network

WAN connectivity is provided via a Commercial Verizon FiOS pipe which is rated at 75Mbps up/down. However, sustained speeds of 100Mbps in either direction are more common than not. Below is a recent Speedtest.net result:

Basic Topology

There is more to my topology, however, this represents the bulk of what's going on behind the scenes.
