Speaker:
Alan Robertson, Senior Software Engineer, IBM.
One of the capabilities most-often identified as being necessary for Linux to be considered a world-class server operating system is High-Availability (HA) services.
High-Availability systems provide the illusion of continuous operation for a cluster of computers where one computer takes over for another in the event of hardware or software failures and planned administrative events.
Linux-HA (http://linux-ha.org) is the oldest, best known and most widely-written about open source HA system available.
The recently released Linux-HA Release 2 extends the capabilities of Linux-HA far beyond anything available in the past, and provides basic capabilities comparable to any commercial HA package.
This release provides capabilities for integrated resource monitoring, larger clusters, for sophisticated resource dependency models, and for integration with cluster filesystems like Red Hat's GFS, and Oracle's OCFS2.
