PowerLinux is the combination of a Linux-based operating system (OS) running on PowerPC- or Power ISA-based computers from IBM.
A survey released by the Linux Foundation in April 2012 showed IBM as the fifth-leading commercial contributor over the past seven years, with more than 600 developers involved in more than 100 open-source projects.
PowerVM for Linux dynamically adjusts system resources to partitions based on workload demands-across up to 640 VMs per server (20 micropartitions per core).
The April 2012 releases by IBM of PowerLinux were designed specifically to run the Linux kernel on the company's POWER7-based systems.
POWER-based servers are virtualized to provide 60 to 80 percent utilization, compared to a typical 40-percent rate for x86 processors.
The PowerVM virtualization program has a Common Criteria Evaluation Assurance (CC) level of 4+, with zero security vulnerabilities reported, as well as unlimited memory use.
