  • okvm – Open source KVM over IP technology – The okvm project team in 2005 developed an open source okvm KVM Development Kit – so engineers could cost effectively roll their own integrated KVM over IP control appliances. These okvm KVM Development kits included: one okvm PCI KVM Adapter card the okvm KVM over IP software source code the source information needed to manufacture the okvm PCI KVM Adapter card (circuit diagrams, BOM,PCD layout etc) A number of the KVM PCI cards were produced – sponsored by Opengear. However this project did not find traction in the developer community. So kits are no longer available and development in this branch of the project has stopped. Also Opengear now sells a proprietary KVM over IP solution!

  • Creating a low cost, high performance ESX cluster | SPK and Associates – As Senior Systems Integrator for SPK and Associates, a California based IT services company specializing in infrastructure management services, I recently completed an interesting project.  The goal was to create an ESX cluster for a small engineering group (about 40 users).  The cluster would be used for a wide variety of applications — software repositories, QA testing of linux appliances, databases, and potentially others as well.  Other than a gigabit network switch and some PDUs, there was no existing infrastructure in place that I could leverage.<br />
    <br />
    For under $18k in hardware, and $7k in VMWare licensing, we were able to build a 2-node VCenter cluster with full HA support.  I expect this to be able to handle upwards of 60 virtual machines, based on typical usage.

  • Building a mail server on Debian 6.0 – The goal of this manual is to provide you with enough knowledge to feel confident in installing and maintaing your own mail server. Of course manuals like this already exist but during my search for knowledge I always felt like they were either not updated in a while or they just skip over some of the most interesting parts assuming you know what they are talking about[…]<br />

  • My Low End VPS Server – This document describes how to setup a Debian Linux VPS to replace your standard shared hosting account.  This document started out as a bunch of scribbles on scrap paper as I built a Virtual Private Server (VPS) into a fully functioning internet server.  It was notes on how I configured the server for the various pieces of the stack.  The need for the server was identified when I wanted to migrate my cPanel Shared Hosting account at Hostgator to a low end VPS for more control and freedom to run whatever software I wanted.  It was also a good opportunity to get back into Linux system configurations and serving web content.  As a collateral benefit, but not as the main drive, I was able to save a few dollars a month in web hosting costs.
