I don't use z/VM for Linux, but when VMWare can give me assurances of 40 years experience in running multiple applications and all (or at least most) of the necessary buttons and knobs to load balance those applications, I will consider VMWare for production applications. > > - doug > > > > > Joseph Temple > <[EMAIL PROTECTED] > com> To > Sent by: Linux on LINUX-390@VM.MARIST.EDU > 390 Port cc > <[EMAIL PROTECTED] > IST.EDU> Subject > Re: Why Zseries > > 02/10/2005 02:10 > PM > > > Please respond to > Linux on 390 Port > <[EMAIL PROTECTED] > IST.EDU> > > > > > > >Let me add to what Joe added. >When you combine the low utilization that many (not all) dense rack >mounted servers run at it becomes even easier for z to win the >througput/KVA race.
