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:
Eliminating Planned Downtime with Zero Downtime Migrations (ZDM), and ZDM for Active/Backup Configurations
How active/backup systems can take advantage of zero downtime migrations by using a fast and reliable failover in order to eliminate planned downtime for upgrades and migrations, and how active/active systems, comprised of two or more nodes cooperating in a common application, achieve continuous availability and eliminate unplanned downtime with zero downtime migrations.
Shadowbase® for HP NonStop®
How Shadowbase for HP NonStop is Gravic’s real-time replication solution for the HP NonStop platform.
Shadowbase® for Open Servers®
How Shadowbase for Open Servers (e.g. Oracle, MS SQL Server, and Sybase and others) is a highly efficient, extremely flexible, robust replication solution based on Gravic’s patented data replication technology and more than 30 years of experience.
Achieving Century Uptimes with Shadowbase® Active/Active Technology
How Shadowbase active/active system architecture provides disaster tolerance by maintaining a network of independent processing nodes, each having access to a common replicated database.
The Evolution of Real-Time Business Intelligence (RTBI)
How the speed of today’s processing systems has moved classical data warehousing into the realm of real-time, or event-driven business intelligence and how to leverage Shadowbase replication technology to implement a real-time event-driven architecture.
