HP believes, based on decades of experience,
that the proper way to achieve high availability for SMP-type
systems involves clustering. We engineer our standalone systems
to be resilient and available, but the highest levels of availability
are achieved with clustering, accompanied by good operational
and system management practices.
The following links take you to pages that discuss how high
availability is defined, what it means to different businesses,
and HP's high availability solutions, documentation, and tools.
The specific focus of this page is to document a real production-level
cluster that resides in one of our Nashua, New Hampshire computer
labs. On October 27, 2000, this two-member cluster was upgraded
to TruCluster Server Version 5.0A from TruCluster Production
Server Version 1.6. Following
the upgrade to Version 5.0A, a rolling upgrade was performed
to install Patch Kit 2.
Since
the initial upgrade and patch, the cluster has been upgraded
to more recent versions of TruCluster Server and the Tru64
UNIX operating system. As of December 2001, the cluster
is running TruCluster Version 5.1 with Patch Kit 3 installed.
We
hope that the configuration and administration decisions we
have made and the lessons we have learned will help you configure
and manage your own clusters.
