Reduce complexity and accelerate your migration with a deployment-ready framework

Dell Mainframe Re-hosting Reference Architecture

Third-party product and sizing guidelines captured in an end-to-end framework to Simplify migration and modernization with a practical roadmap help reduce for success Today’s businesses are looking for ways to reduce costs and enhance operational migration effectiveness by moving existing mainframe applications to flexible, modern project time and IT systems. However, complex supporting environments consisting of proven standards and procedures, in addition to a mature third-party product infrastructure minimize risk. commonly associated with mainframe applications can add complexity and impact your decision and timeline to migrate. By providing a framework which addresses not only specific application requirements, but also the related operational infrastructure commonly found on mainframe systems, the Dell™ Mainframe Re-hosting Reference Architecture (MRRA) provides an end-to-end roadmap for moving mainframe application environments to industry-standard systems.

Tested and tuned IT framework simplifies migration Key benefits Dell offers Operational and Infrastructure-related assessment services to better • End-to-end framework for re- understand existing mainframe and distributed environments, in terms of hosting mainframe workloads on infrastructure, skills, processes, standards and products. One of the key deliverables open systems of these assessment services is a fully tested, tuned and documented reference • Offers extensive compatibility with architecture to support a re-hosted mainframe workload on distributed systems. It legacy environments to help reduce addresses the criteria essential for you to design, deploy and maintain successful migration risk, time and complexity mainframe migration implementations. Based on Dell Mainframe Re-hosting • Preserves existing investments in software and select third-party infrastructure products, Dell MRRA helps reduce personnel, code, data and end user migration risk, cost and deployment time, and assists you in efficiently moving interfaces mainframe workloads to robust and cost-effective platforms. The flexible nature of • Provides a practical platform for Dell MRRA simplifies migration to an existing distributed-computing infrastructure future application evolution or eases a move to a new target implementation. Considerable emphasis in Dell MRRA is placed on the third-party products that offer key functionality such as scheduling, print and output management, systems and performance management, database management and security. Unlike alternative approaches that can limit you to an individual product suite, Dell MRRA provides an open framework that enables you to tailor a mainframe migration implementation to your specific business needs.

After deployment, the Dell MRRA can enable you to further modernize your application environment with enhancements to basic functionality, system interoperability and end-user interfaces. Dell MRRA demonstrates how re-hosted applications can be extended with technology such as Dell Service Builder and Dell Web Connect. These software products can provide the ability to generate web services against 3270-based applications, or to dynamically translate 3270 data streams into web interfaces.

Multi-layered deployment architecture addresses the complete picture Every time you utilize the Dell MRRA, you can rest assured that Dell has completed the due diligence required to architect a complete implementation designed to deliver results. The Dell MRRA application architecture consists of distinct platforms (see Figure 1): • Application and database servers - Provides the necessary production platforms for supporting the re-hosted workloads. Solutions running on these platforms include Dell Mainframe Re-hosting software, relational databases and supporting third-party products. • Development - Includes all the necessary development, debugging and test-related solutions required to support and modernize the re-hosted applications. • Systems management - Provides a dedicated platform for monitoring the health of the application and systems environment.

The Dell MRRA can be implemented to meet elevated availability requirements. A systematic approach is taken to illustrate redundancy, fault isolation and rapid recovery options.

The Dell MRRA scales from small, single or dual-processor servers up to massive symmetrical multi-processing systems, all using the same binary code. As resource demands grow with more users, transactions, data sets or other variables, the architecture can scale seamlessly to meet evolving needs.
