I am not making a claim to fame (OK, I am really) but the UK Power Systems Advanced Technical Support group (that is me and Gareth) dropped the term "LPAR" or Logical Partition as a New Years resolution. We like to occasionally test to see if we can influence other IBMers and the IT Industry. We now in 2011 onwards use the terms:
- Virtual Server - this is the term used by Systems Director for over three years. While I can live with that name but the abbreviation of VS - it just does not feel or sound right.
- Virtual Machine - this term is more widely used and the abbreviation of VM is readily understood in the IT industry. Even used in "Power-land" in product names like PowerVM. Of course, VM is an IBM operating system for the mainframe and used for many years (if not decades).
So the observant might have noticed a sharp decline in the term LPAR in the last 3 or 4 months. Apparently, and three months later, this change in now recommended within IBM and IBM marketing, so you will see a lot more use of the new terms. This is a change in name that I whole heartedly approve ... unlike, for example, RS/6000 to pSeries to System p to Power Systems (which now confuses the worlds fastest general purpose computers with mains electricity power supplies!). Of course, "LPAR" will turn up out of habbit on the Internet, documents and articles for many years to come and be popular with IT Luddites now that is old fashioned :-)
Oddly, I tend to use Virtual Server
and VM for short
on diagrams or presentations to save space - oh well, it is still better than the L-word.
When I think back to it, the Logical Partition (LPAR) name never did make much sense!
- Logical - means shared or pretend or not physical
- Partition - means a part of the whole and started life as a disk term as a group of sectors
OK, when the POWER4 pSeries 690 arrived in the year 2000 (approximately), we used the "LPAR" term to explain the carving up of a large machine in to parts - where the system admin person decides the number of CPUs but not the actual physical CPUs allocated ... hence Logical. I am not sure in 2000, we were expecting "LPAR" to become such an over used term or noun - but I could be wrong.
So if you want to be seen as young, hip, modern and receptive to new thoughts and movements (and not stuck in your ways, old fashioned or out of date):
and call it what it actually is:
Comments welcome - where did I put that those flame proof clothes?
- Virtual Server or Virtual Machine (VM)
