Linux development to get high availability push

06.04.2011
The Linux Foundation has formed a new working group to speed development within the Linux ecosystem that would make the operating system kernel more suitable for building high-availability (HA) systems, the Foundation announced Wednesday.

The High Availability Working Group will define a software stack for running Linux in clustered, mission-critical environments. It will also prioritize development work that still needs to be done, based on feedback from developers, vendors and customers.

Engineers from Novell, Oracle and Red Hat, among other companies, will participate in the working group, as well as leaders from Linux distributions such as Debian, Fedora, OpenSuse and Ubuntu.

"The users [of the stack] would be everyone who wants to run a Linux cluster on open-source software," said Lars Marowsky-Bree, a Novell engineer who is the working group's architect. While Hewlett-Packard offers a HA package for Linux, and Red Hat offers HA capability in a preview mode for Red Hat Enterprise Linux, users have been requesting a fully open-source and vendor-neutral package, Marowsky-Bree explained.

The Linux Foundation defines high-availability computing as systems that maintain at least 99.999 percent (or "five nines") uptime. This translates to about five minutes and 26 seconds of downtime per year.

Over the past few years, HA system builders have tended to use commodity hardware, with extra, normally redundant equipment in place to ensure the systems keep running even when individual components fail.
