IBM has announced an open beta version of virtualisation software that lets x86 Linux applications run on Power processor-based IBM System p servers.

The IBM System p Application Virtualisation Environment – known as System p AVE - allows thousands of Linux applications to run unmodified on System p AIX servers. The software follows IBM's introduction of three System p servers designed to consolidate Linux workloads.

Already nearly 2,800 applications run natively on Linux on System p servers. System p AVE will allow even more applications to run unmodified, as well.

System p AVE creates a virtual x86 environment and file structure and executes x86 Linux applications by translating and mapping x86 instructions and calls to the Power architecture. Because it uses caching, an application's performance can increase over time. While there is a performance penalty of about 10% associated with the use of p AVE for some applications, the caching capability lessens it.

IBM said that allowing Linux applications to run on the System p is important as the company's recent research showed that each pSeries server sold in the first quarter of this year had an average of 30 logical Linux partitions per server.

The System p server had a revenue share of more than 30% of the 2006 Unix server market, analyst firm IDC said.

The software is expected to be available in the second half of this year.
