[Wlug] MySQL Server Hardware

[John Westcott, IV]

Howdy All,
  I work in a place that has traditionally used Sun Sparc hardware 
running Solaris to host a production MySQL environment.
  We are going to be replacing our database servers this year and I am 
trying to determine if I want to maintain the norm or if I want to try 
to change.
  I am interested to see what other people use for hardware/OS for a 
production MySQL installation that requires a high amount of uptime.
  Thanks in advance for any replies.
