Goal

We have 10 application servers that are used in our Dev, Test, and Production environments. We have continuous need for additional HW to either bring up additional environments, as described bellow, or to run specific support applications and or scripts.
Currently we need applications servers for the following:

  1. SmartSite Beta environment where we stage new tools and or new Sakai versions
  2. Server where we can run our support scripts such as
    • DB Helthcheck, which detects full table scans
    • Number of sites created in form of a spreadsheet
  3. Apache to host ucd-gateway and ucd-help
  4. Apache to host maintenance and outage pages
  5. Apache to host maven1/maven2 repositories
  6. Environment to host the SCORM tool while in development
  7. Having four separate environments, DEV, TEST, INTG, PROD. We always trade off one of these environments

Given the budget constraints, we are not really in a position to purchase new HW and thus need to find other solutions to accommodate our HW needs. One of the potential solutions is to virtualize one or more of our environments to optimize the use of our available HW.

All of our applications nodes have enough CPU and RAM resources in order to run more than one virtual machine. The initial goal is to virtualize the following HW/Environments:

  1. node: Sakai 2.5.x for QA and practice roll out environment. Hardware needed now. We can use smartsite_ng1 and the corresponding RAC instance for smartsite_ng for this environment now. After the roll out, we can return it to the Beta environment usage.
  2. node : sakai-dev/test/intg, not needed now (isaac)
  3. node : smartsite-beta (provided with Banner data but for users to play with), hardware needed by end of March
  4. node : most of the supporting scripts, apache to run maintenance pages, ucd-gateway, and ucd-help -- production executables, hardware needed now
  5. node : redundant of node 3, hardware needed now
  6. node : sakai-beta 2.5.x -- one release ahead of our current release, hardware needed later
  7. node : sakai contrib -- new tools that we don't have in prod yet but we want to evaluate, using stubing for this now
  8. node : smartsite contrib -- Tools: SCORM and course evaluation, hardware needed now
