IBM reveals new virtual Linux environment
|
|
IBM has announced the availability of an open beta version of its virtual Linux environment to enable x86 Linux applications to run without modification on POWER processor-based IBM System p servers. Designed to reduce power, cooling and space by consolidating x86 Linux workloads on System p servers, it will eventually be released as the roles off the tongue ‘IBM System p Application Virtual Environment (System p AVE).’

So what exactly is IBM System p AVE technology in a nutshell? Initial testing shows that clients should be able to easily install and run a wide range of x86 Linux applications on System p and BladeCenter JS20 and JS21 servers that are using a Linux operating system. These applications should run, without any change to the application and without having to predefine that application to the Linux on POWER operating system with p AVE installed. The system will "just know" the application is a Linux x86 binary at runtime and run it automatically in a p AVE environment. Behind the scenes, p AVE creates a virtual x86 environment and file structure, and executes x86 Linux applications by dynamically translating and mapping x86 instructions and system calls to a POWER Architecture processor-based system. It uses caching to optimize performance, so an application's performance can actually increase the longer it runs. Using p AVE, IBM expects ISVs that don't already have a native Linux on POWER product to be able to expand their addressable market to System p servers at minimal cost by allowing them to run their existing x86 Linux applications on these servers without having to recompile, release new media or documentation, or maintain a unique product offering for POWER technology.
