      1Building a Virtualized Testbed on the Cheap – Part I: Hardware and Layout

      2Hardware Used

      I only used hardware lying around the lab, none of which is particularly powerful or modern. There will be shortcomings in the ESXi testbed, particularly a lack of 64-bit client support as none of the processors supports virtualization extensions.

      With this hardware plus a SATA RAID controller and some USB sticks, I built one virtual host, an iSCSI NAS appliance and a management workstation. It’s a flexible architecture that will allow me to easily share already built virtual machines with any additional ESXi servers I add to the network at a later time.

      4Software Used

      Most of the software used in this demonstration is either free or available as a shareware trial. Hopefully, most of you have already invested in some CD burning software.

      Thankfully, my motherboard supported dual processors, so I combined the AMD Opteron 246 processors and RAM from both Opteron machines into one chassis. Because the ESXi footprint is so small, we don’t need a hard drive in the ESXi server; we can instead boot and run the software from a 1GB USB stick.

      6Building a NAS

      I added both the 120GB hard drives from the Opteron servers to the 120GB disk already in this machine. This gave me a 360GB RAID 0 array to use for my iSCSI server. OpenFiler works with the 512MB of RAM I have in this machine, although I would recommend bumping it up to 1GB.
