Yeah nah. Mainframes have:

  * hot-swap power & CPUs
  * RAS (Reliability, Availability, Serviceability)
  * vendor SLAs
  * fault containment
  * designed uptime vs achieved uptime

If you can buy replacement parts on eBay and reboot to fix problems, it’s not a mainframe.

According to Merriam-Webster:

  mainframe (noun)
  main· frame ˈmān-ˌfrām 

  1: a large, powerful computer that can handle many tasks concurrently and is usually used commercially
  2: (dated): a computer with its cabinet and internal circuits especially when considered separately from any peripherals connected to the computer

The features you list are great to have, but my setup fits the first definition of mainframe as described. If you feel this definition is not specific enough, email Merriam-Webster and don't bother me about it.

Webster is wrong. A mainframe is not a generic high performance computer (that would be HPC). A mainframe is a very specific high performance computer.

I repeat: I understand that mainframe has a specific meaning to many people, especially those who work on traditional mainframes, but I would rather you and the other user to email both Google and Merriam-Webster about their wrong definitions, and not bother me about it. I will correct my usage once they have updated the definition to your standards.
