HP Software Cluster products
The HP Software Cluster products include HP Serviceguard and the technologies built on top of it.
These topics are discussed in the following sections.
What is HP Serviceguard?
HP Serviceguard is available as a stand-alone product and as part of the mission-critical operating
environment (MCOE). It protects mission-critical applications from hardware and software failures. To
deploy Serviceguard, you organize multiple systems into a cluster. You then create packages (each
with its own IP address) for your important applications. Each package can run on multiple nodes in
the cluster. (You do not need to modify your applications to work with Serviceguard.) With the cluster
and packages configured, Serviceguard monitors the health of each of the systems and packages. If a
failure occurs, Serviceguard automatically restarts an application (fails over the application) on a new
system or partitionreducing or even eliminating application downtime.
Serviceguard packages provide a simple, flexible framework for managing application resources.
You can create up to 150 packages; multiple packages can run on each of the nodes within the
cluster. Figure 1 illustrates example components of a Serviceguard package.
