Storage Expert components include a set of rule scripts and a rules engine. The rules engine runs
the scripts and produces ASCII output, which is organized and archived by Storage Expert’s report
generator. This output contains information about areas of VxVM configuration that do not meet
the set criteria. By default, output is sent to the screen, but you can redirect it to a file using
standard UNIX redirection. See the VERITAS Volume Manager Administrator’s Guide for more
information.
Cluster Functionality (Optional)
VxVM includes an optional, separately licensable clustering feature, known as Cluster Volume
Manager, that enables VxVM to be used in a cluster environment. With the clustering option,
VxVM supports up to 16 nodes per cluster. See the VERITAS Volume Manager Administrator’s
Guide for more information.
VERITAS Volume Replicator (Optional)
VERITAS Volume Replicator (VVR) is an optional, separately licensable feature of VxVM. VVR
is a data replication tool designed to maintain a consistent copy of application data at a remote site.
It is built to contribute to an effective disaster recovery plan. If the data center is destroyed, the
application data is immediately available at the remote site, and the application can be restarted at
the remote site.
VVR works as a fully integrated component of VxVM. VVR benefits from the robustness, ease of
use, and high performance of VxVM and, at the same time, adds replication capability to VxVM.
VVR can use existing VxVM configurations with some restrictions. Any application, even with
existing data, can be configured to use VVR transparently.
See the VERITAS Volume Replicator documentation for more information.
