The original goals and design principles as outlined here are still valid for the new build, a summary:
- Low power consumption (equal or less than my current single host)
- Be as small as possible
- Silent running
- Enable high availability for VM’s
- Based completely on Microsoft technology
- Must be easily scalable and feel “enterprisy”
- Low cost solution!
For moving to the new platform I’ve decided to do a full bare metal install, no in-place upgrade.
- Reuse the existing hardware
- Reusing the nodes boot LUNs (erase and reinitialize)
- The existing VM’s are on a separate LUN and can be reused on the new platform.
- The storage design will stay the same
- Keep the domain controller on the cluster
- The network design has changed to allow for more flexibility and security
- The core VM servers (AD,DNS,etc) will move to Server 2012
- Increase security by splitting the domains
