SUSE Linux Enterprise High Availability Extension's powerful graphical and command line tools let you save time and be more productive.

Virtual servers are increasingly being used by organizations seeking to improve resource utilization and responsiveness.
Many IT managers like you are looking at clustering virtual servers together to improve services availability, since the low overhead associated with a virtual standby node makes it well suited for this purpose. As workloads become consolidated among fewer physical servers, it becomes increasingly important that those systems be highly available.

SUSE Linux Enterprise High Availability Extension is one of the few clustering solutions available in the market, today, that supports the mixed clustering of both physical and virtual Linux servers. This versatile solution offers you unprecedented flexibility, and enables you to simultaneously improve both services availability and resource utilization.

The cluster resource manager in SUSE Linux High Availability Extension is able to recognize, monitor, and manage services running within virtual servers, as well as services running on physical servers. Virtual servers can be clustered together and services can even be clustered within a virtual server. Moreover, virtual servers can be clustered with physical servers, and physical servers can be clustered with each other, extending high availability from virtual to physical workloads.

The ability to encapsulate entire workloads within virtual guests means that you can easily replicate and manage them using the tools and capabilities provided within the solution, such as DRBD, OCFS2 and cLVM2. SUSE Linux Enterprise High Availability Extension's support for virtualized environments gives you unprecedented flexibility to improve services availability as well as resource utilization.
