Continentalclusters Product Features
The Continentalclusters product has the following basic features:
• Continentalclusters works with any type of data replication. A set of guidelines for integrating
your data replication technology can be found in Chapter 2 of the Designing Disaster Recovery
HA Clusters Using Metrocluster and Continentalclusters guide available at: www.hp.com/go/
hpux-serviceguard-docs.
Continentalclusters provides a pre-integrated data replication solution using HP StorageWorks
Continuous Access P9000/XP, Continuous Access EVA, 3PAR Remote Copy, or EMC SRDF
with the separately purchased products Metrocluster with Continuous Access for P9000 and
XP, Metrocluster Continuous Access EVA, Metrocluster with 3PAR Remote Copy, or Metrocluster
with EMC SRDF.
• A recovery pair in a Continentalclusters consists of one primary cluster and one recovery
cluster. One or more recovery pairs can be configured in a Continentalcluster with a common
recovery cluster. Failover of a specific package occurs in one direction from the primary cluster
to the recovery cluster. Each data center can serve as both primary and recovery cluster for
different packages. In the cascading failover configuration, the primary cluster can be a
Metrocluster using EMC SRDF or Continuous Access P9000/XP.
• Logical data replication of Oracle Databases is possible using Oracle Data Guard.
Serviceguard support for Oracle Data Guard in Continentalclusters is available in Serviceguard
toolkit for Oracle Data Guard (a separately purchased product). Other customer-selected
logical data replication solutions can be implemented as well. For more information see, HP
Serviceguard Toolkits for Database Replication Solutions User Guide available at http://
www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard Toolkit for Oracle Data Guard.
• Cluster monitoring is carried out over LAN or WAN connections. Use any LAN or WAN
connection; however, some data replication methods may require high speed connections
such as T1, T3, E3/ES or ATM leased lines or switched lines.
Support for IPv6 Protocol
Starting with Continentalclusters version A.08.00, primary and recovery clusters in
Continentalclusters can be configured with IPv6 address. Additionally, notifications provided for
cluster events can use an IPv6 address.
IMPORTANT: A mixed cluster configuration, in which one cluster is configured with the IPv4
protocol, and the other cluster with the IPv6 protocol, is not supported.
Enhanced Security Infrastructure
Continentalclusters version A.08.00 uses a secure infrastructure. The following components are
used in Continentalclusters A.08.00:
• Continentalclusters User and Group
Continentalclusters version A.08.00 uses Secure Shell (SSH) for all inter-cluster and node
communication. A special Continentalclusters user, conclusr and group, conclgrp are
used for all communication over SSH. This Continentalclusters user and the group are
automatically created when Continentalclusters version A.08.00 is installed on a node. You
