AIXpert Blog is about the AIX operating system from IBM running on POWER based machines called Power Systems and software related to it like IBM Systems Director, PowerVM for virtualisation and PowerSC for security plus performance monitoring and nmon
Finally, I have the types of memory by POWER7 model double checked. I refreshed the table in part 1 but thought I should make sure every one sees the final version so I have not mislead people. Only the Power 770/780 and Power 797 have Near memory. All the smaller machine operate a Local memory meaning on the same same POWER7 chip and Far memory for any access to another POWER7 chip's memory.
Update in 2016: Please note this blog is from 2011 during the initial POWER7 days and technology has moved on with faster CPUs and memory in addition there has been software improvements. I am amazed how many good computer people read this and assume this blog is true to all time! Virtual Ethernet is faster now but there is also a warning here. Here is an analogy. Most vehicles can do 10 MPH (including me on a bike), most cars can do 100 MPH (including my family car) but very few vehicles can do 1000 MPH. That last times ten multiplier is... [More]
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... [More]
