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.
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]
I have had a couple of Power systems administrators make assumptions about the virtual Ethernet speed improvements when they install a 10 Gb IVE/HEA in a VIOS which are simply not true. I guess that if three teams have made this mistake then others are about too. So I intend here to put the record straight. The expectation is that (deliberately fully spelt out long-hand to make it very clear): When they upgrade the Integrated Virtual Ethernet (also called a Host Ethernet Adapter) from 1 Gigabit per second to 10 Gigabit per second that the...
