Roadmap to the Megaplex (Hardbound copy request)
The “Roadmap to the Megaplex” report comprises six steps to NonStop modernization and to the Megaplex. (A collection of server blades acting together as a single system using multiple types of operating systems, databases, and other computer resources.) Each step includes: an introduction, a profile of a major vendor and the technologies that help implement the step, a modernization case study, a simulated return on investment example, a benefit checklist, and alternative vendor product. Step 4: Availability Modernization: The process of changing from the traditional availability and disaster recovery methods to a continuous-readiness program. The vendor/product profiled is Gravic’s Shadowbase, which provides for active/active processing and zero-downtime migration and upgrades.

White Papers:

Shadowbase® Streams for Application Integration
The Shadowbase product suite from Gravic, Inc., distributes real-time critical data to applications throughout the enterprise. Uses for Shadowbase products include achieving high or continuous availability by synchronizing active or passive redundant systems, integrating applications, feeding data warehouse and real-time business intelligence facilities, and driving ETL (extract, transform, and load) utilities. Shadowbase Streams, a member of the Shadowbase software solutions set, streams data generated by one application to other applications and facilities. Shadowbase Streams for Application Integration provides the facilities for integrating existing applications at the data or event-driven level in order to create new and powerful functionality for the enterprise.

Choosing a Business Continuity Solution to Match Your Business Availability Requirements
Business continuity encompasses those activities that an enterprise performs to maintain consistency and recoverability of its operations and services. The availability of application services provided by an enterprise’s IT infrastructure is only one of many facets of business continuity, albeit an extremely important one. Application availability depends upon the ability of IT services to survive any fault, whether it is a server failure, a network fault, or a data center disaster. An enabling technology for achieving high availability and even continuous availability for application services is data replication. Selecting the right data replication technology to achieve your business continuity goals is the focus of this white paper. We also summarize the Shadowbase® suite of replication products from Gravic, Inc. Shadowbase software provides the full range of replication technologies to satisfy the most demanding IT availability requirements.

Using Shadowbase to Eliminate Planned Downtime via Zero Downtime Migrations
How to totally eliminate planned downtime for your application services when performing migrations, upgrades, conversions, or other disruptive system activity, regardless if performing a homogeneous or heterogeneous project. This paper explains the exclusive Shadowbase Zero Downtime Migrations (ZDM) approach to improve your application availability for providing high and even continuous availability application services.
