Overview

IBM Implementation Services for Geographically Dispersed Open Clusters (GDOC) is a multi-vendor solution designed to protect the availability of critical applications that run on UNIX®, Microsoft™ Windows™, or Linux™ operating system based servers. GDOC is based on an Open Systems Cluster architecture spread across two or more sites with data mirrored between sites to provide high availability and disaster recovery. It is designed to provide you with similar functionality for open systems that GDPS™ provides for the IBM System z™ mainframe. This type of solution can provide a much shorter recovery time for critical business applications, and is easier than recovering from tape backup, or replicating data with manually initiated recovery processes.

GDOC is a services framework and methodology that includes the integration of Veritas Cluster Server and associated software modules from Symantec Corporation. The solution comes with a base set of implementation services including:

  • Consulting and planning
  • Design
  • Solution build
  • Testing and deployment

Description

IBM Implementation Services for Geographically Dispersed Open Clusters addresses the automation, testing, and management requirements of a disaster recovery solution using proven methods and automation software from Symantec. GDOC provides the mechanisms to automate, test, and manage disaster recovery, while allowing some flexibility in the product selection for storage and replication technology. It is also designed to assist you with:

  • Implementing and managing data replication across sites
  • Automating data recovery (wide-area failover and switchover) at a secondary site
  • Managing, monitoring, and testing your disaster recovery solution

GDOC supports the following platforms:

  • AIX®
  • Hewlett-Packard UX
  • Linux
  • Microsoft Windows
  • Solaris
  • Red Hat Linux and SUSE Linux

The GDOC solution is designed to provide you with similar functionality for open systems that GDPS provides for the IBM System z mainframe. The solution typically begins with a cluster of servers that provide high availability within a data center and is extended by adding additional copies of data and additional servers at a geographically remote data center. While clustering within a data center provides high availability, clustering across data centers, with an additional remote copy of data, provides important disaster recovery capability. The end result is an improved ability to recover from a disaster quickly with minimal data loss. This type of solution provides a recovery time, for critical business applications, that is typically much shorter and easier than recovering from tape backup or replicating data with manually initiated processes.

The GDOC solution is designed to coordinate data consistency and recovery for multiple vendor operating system platforms (AIX, Solaris, HP-UX, Linux, and Microsoft Windows) between data centers. Data between the data centers is kept in sync using a data replication solution. The GDOC solution allows for different replication technologies including but not limited to: IBM DB2® HADR, IBM Metro Mirror, Hitachi TrueCopy, EMC MirrorView, Network Appliance SnapMirror, EMC Symmetrix Remote Data Facility, and Veritas Volume Replicator. The GDOC solution is applicable when the high availability and disaster recovery requirements are not met by solutions like IBM Continuous Availability for AIX, IBM Continuous Availability for Microsoft Windows, and IBM Tivoli® Systems Automation.

GDOC is a services framework and methodology that includes the integration of Veritas Cluster Server and associated software modules from Symantec Corporation. The GDOC implementation service is designed to deliver an end-to-end solution that may provide:

  • Server and data disaster recovery planning
  • Business impact analysis
  • Risk analysis
  • Bandwidth analysis
  • Enterprise architecture design
  • Network design

This solution includes the following base set of services:

  • GDOC consulting and planning — An assessment of the high availability/rapid recovery solution requirements. During the planning stage, the desired state is defined, as well as the steps needed to achieve the desired state. This stage is often accomplished through a GDOC Technology Consulting Workshop (TCW) engagement.
  • GDOC conceptual, logical, and physical design — Designs the solution infrastructure to meet the business requirements and objectives. It also provides the technical definition for the physical infrastructure.
  • GDOC non-production solution build and test — Takes the conceptual, logical, and physical design, including prototype and proof of concept if applicable, and implements it in the customer's environment in a test capacity.
  • GDOC solution roll-out and deployment — Takes the prototype and test implementations and builds an enterprise-wide roll-out strategy that enables you, with IBM, to begin a production roll-out in your environment. IBM will educate you so that you can continue this roll-out process independently.
