Guide to Disaster Tolerant Solutions Documentation

This edition divides the contents of the former guide, “Designing Disaster Tolerant High Availability Clusters”, into the following two separate guides:

Understanding and Designing Serviceguard Disaster Tolerant Architectures
Designing Disaster Tolerant HA Clusters Using Metrocluster and Continentalclusters

The Understanding and Designing Serviceguard Disaster Tolerant Architectures guide provides an overview of Hewlett-Packard Disaster Tolerant high availability cluster technologies and how to configure an extended distance cluster using Serviceguard. It is assumed you are already familiar with Serviceguard high availability concepts and configurations.

The contents are as follows:

Chapter 1, Disaster Tolerance and Recovery in a Serviceguard Cluster, is an overview of disaster tolerant cluster configurations.
Chapter 2, Building an Extended Distance Cluster Using Serviceguard, shows the creation of disaster tolerant cluster solutions using extended distance Serviceguard cluster configurations.

The Designing Disaster Tolerant HA Clusters Using Metrocluster and Continentalclusters guide provides detailed, task-oriented documentation on how to configure, manage, and set up disaster tolerant clusters using Metrocluster Continuous Access XP, Metrocluster Continuous Access EVA, Metrocluster EMC SRDF, Continentalclusters, and Three Data Center Architecture.

The contents are as follows:

Chapter 1, Designing a Metropolitan Cluster, shows the creation of disaster tolerant cluster solutions using the metropolitan cluster products.
Chapter 2, Designing a Continental Cluster, shows the creation of disaster tolerant solutions using the Continentalclusters product.
Chapter 3, Building Disaster Tolerant Serviceguard Solutions Using Metrocluster with Continuous Access XP, shows how to integrate physical data replication via Continuous Access XP with metropolitan and continental clusters.
Chapter 4, Building Disaster Tolerant Serviceguard Solutions Using Metrocluster with Continuous Access EVA, shows how to integrate physical data replication via Continuous Access EVA with metropolitan and continental clusters.
Chapter 5, Building Disaster Tolerant Serviceguard Solutions Using Metrocluster with EMC SRDF, shows how to integrate physical data replication via EMC Symmetrix disk arrays. Also, it shows the configuration of a special continental cluster that uses more than two disk arrays.
Chapter 6, Designing a Disaster Tolerant Solution Using the Three Data Center Architecture, shows how to integrate synchronous replication (for data consistency) and Continuous Access journaling (for long-distance replication) using Serviceguard, Metrocluster Continuous Access XP, Continentalclusters and HP StorageWorks XP 3DC Data Replication Architecture.

A set of appendixes and a glossary provide additional reference information.

Table 2 “Disaster Tolerant Solutions Document Road Map” outlines the types of disaster tolerant solutions and their related documentation.
