IBM released z/VM 6.1 at the end of October. They had previewed it back in the spring and said it would be ready to go by the end of the year. Well, it’s ready to go. The announcement letter sums up some of the new features:

  • Enhanced performance of virtual networking environments running heavy guest-to-guest streaming workloads
  • Faster access to data when utilizing FICON Express8
  • Closer integration with IBM Systems Director to eliminate the need to download agents and help simplify the installation of those agents
  • Significantly better and more highly secure guest transactions when using Crypto Express3 as compared to Crypto Express2
  • Guest support for IBM System Storage DS8000 Extended Address Volumes (EAVs) to help simplify storage management and relieve address constraints

z/VM has become a truly important technology for IBM and mainframers alike, as the influx of people using it as the foundation to run zLinux has increased sharply over the past couple years.

And since it has been around for decades, z/VM has a lot of advanced virtualization features that other virtualization platforms don’t have, according to Clabby Analytics President Joe Clabby.

“It is the best virtualization platform,” he said. “It’s constantly raising the bar. Virtualization capabilities on the mainframe are a decade ahead of where x86 is right now, and a few years ahead of Power.”
