Hmmmm Now this is interesting. Way back, when I was a VM systems programmer, we used to refer to a virtual machine as a, errr, virtual machine!. An LPAR, I think, was a hangover from PR/SM terminology ? Used mainly by the MVS folk. I guess the term carried on over into pSeries, POWER systems. VM or Virtual Machine does make more sense to me. <div>&nbsp;</div> Cheers!

we gonna get a new a name for WPAR's then? maybe sub machines? err wait.. that'd be SM, nevermind... virtual guests? vg's? hah nope. <div>&nbsp;</div> vApp's? nah, VMWare coined that for a total software stack of VM's.. <div>&nbsp;</div> i guess "WPAR" still makes sense on an Virtual Machine, wonder what it'll morph into over the next several years. <div>&nbsp;</div> seriously though, in my org at least they're referred to as everything from LPAR to VM's, "guest VMs" and even just plain old "images".

OK OK, point taken, I'll start saying "VM" - if somewhat begrudgingly :-) <div>&nbsp;</div> But the L word will never die !!! <div>&nbsp;</div> It'll be riddled into the system and will continue to crop up in various places as a wonderful reminder of days gone by. <br /> Eg. the HMC cli (chhwres, chsysres, etc) and libperfstat.h. <br /> If IBM want to eradicate it from our memory, they're going to need to change all these references. <div>&nbsp;</div> And on the subject of giving things names which reflect what they really are, since when has that ever been a priority ? <br /> It's all about sales &amp; marketing - and in fact you often see things mis-named deliberately to give the customer the impression it's something it's not. <div>&nbsp;</div> Which leads me on nicely to "WPAR". <br /> IMO it's not even really a guest VM, because it's not a virtual "machine" as such. More of a virtual operating system. <br /> In the Linux world, I liked the term "User Mode Linux", so how about "User Mode Operating System or UMOS". <br /> More accurate, but yuk ! <div>&nbsp;</div> Remind me, what was wrong with LPAR and WPAR ? ;-)

it must be an ibm disease to change names of something that works perfectly fine. i'll stick with lpars, wpars and vios ;-)

I would prefer seeing existing problem fixed prioritized higher than inventing new names for existing things. <br /> maybe a thread: "things we like IBM to fix in AIX, PowerVM, Tivoli Monitoring, Systems Director, PowerHA and TSM" would result in some pretty interesting feedback. anyone make a start? <div>&nbsp;</div> cheers

I can get used to changing <br /> LPAR -&gt; Virtual Server (but not the lparstat command!) <br /> but WPAR staying the same <br /> VIO Server -&gt; Utility Virtual Server (but keep the commands ioslevel, backupios and updateios) <br /> Machine -&gt; server (except in Virtual Machine, and NIM "machines") <div>&nbsp;</div> but please, PLEASE, don't let them ever change "AIX" to "IBM a" (to match "IBM i"). I hereby patent the term "IBM a" which would make all useful web searches impossible.

Does it mean that 'Unix LPAR' and 'Linux VM' are synonims? I am just preparing a document for a customer. In his mail there are both terms. I mam not sure what to do with that... Could you help me, please?

LPAR = Logical Partition is an IBM term used for Power Systems and means the same as a VM = Virtual Machine which is the normally used industry term. UNIX (like AIX) and Linux (like SUSE/Red Hat) are very different operating systems but have the same or similar concepts, user commands, programming interface and general feel.
