IBM pumps up Linux virtual machines on mainframe OS
Organizations running Linux in virtual machines on the mainframe will soon be able to throw more workloads onto the system thanks to an update to the z/VM operating system that now scales across 32 processor units, compared with the previous version that scaled to 24. The new release, z/VM Version 5.3, is expected to begin shipping on June 29, but IBM detailed updates to the operating system on Tuesday.
