Conducted at the DataDirect Technologies' mainframe products development lab in Sugar Land, Texas, test parameters compared the previous version of the DataDirect Shadow product against the current, version 7 release. Initial performance tests were run for each of the major mainframe Web services provider integration types supported by the DataDirect Shadow product including business-logic integration, screen-logic integration and data-logic integration. Test results showed an impressive 170 percent average increase in transactions per second across all three integration types with business-logic integration services delivering the greatest throughput performance increase of 300 percent.
The transformation of mainframe applications into reusable, Web services and the ability to access data via Web services are elemental requirements for an organisation when evolving toward a SOA. The barrier for entry into SOA is higher with mainframe systems given the processing costs associated with Web services. These costs are expected to increase as mainframe SOA adoption matures and the complexity of Web services on the mainframe grows.
DataDirect Shadow version 7 was designed to improve performance and lower costs associated with mainframe SOA enablement. As the first mainframe integration middleware to capitalise on the inherent performance and cost advantages of the IBM specialty engines, DataDirect Shadow version 7 opens the System z9 Integration Information Processor (zIIP) to additional workloads beyond DB2, including mainframe data queries to IMS, VSAM, Adabas and IDMS, as well as SOAP/XML parsing for the transformation of business logic and screen logic into Web services. With the DataDirect Shadow product's patent-pending design, SOA integration processing and data queries can be diverted from the mainframe's General Purpose Processor (GPP) and offloaded to the zIIP and/or System z Application Assist Processor (zAAP) specialty engines.
In the Gartner, Inc. research brief, IBM Mainframe Specialty Engines Affect General Purpose Processor Performance, May 27, 2008 analysts John R. Phelps and Mike Chuba conclude in their recommendations, "specialty engines, regardless of multiprocessing (MP) ratio impact, represent the most attractive price/performance environment for a mainframe..."
"From a technology perspective, we have solved the bulk of mainframe integration challenges with SOA. The bigger hurdle has been making SOA cost effective for the mainframe, which the DataDirect Shadow product delivers through its unique ability to divert processing intensive workloads away from the mainframe GPP to non-measured specialty engines," said Gregg Willhoit, chief architect of the Shadow product at DataDirect Technologies. "Performance tests conclude on average, 76 percent of DataDirect Shadow version 7 processing can be diverted to the zIIP specialty engine, with improved performance and the potential for significant cost savings."
Costing models using the DataDirect Shadow mainframe SOA performance benchmarks demonstrate how an organisation can lower the mainframe Total-Cost-of-Ownership (TCO). Assume a 20 percent Compound Annual Growth Rate (CAGR) for the System z computing power calculation, Millions of Instructions Per Second (MIPS), with a current capacity utilisation rate of 66 percent, and an average incremental SOA processing load of 10 percent. With traditional solutions, an organisation will require a mainframe capacity upgrade in the first year in order to avoid capacity constraints. Utilising DataDirect Shadow version 7 for Web-services transformation and assuming a 70 percent SOA offload rate to the zIIP specialty engine, the organisation could potentially delay a mainframe capacity upgrade for another 12 months. In addition, the total MIPS required are on average 6.8 percent less due to the efficiencies of DataDirect Shadow version 7. Consider the fully loaded costs of a single mainframe, where licensing software based on MIPS can run into the hundreds of thousands of dollars, the savings provided by DataDirect Shadow version 7 are significant and provide a measurable way to reduce the TCO for the mainframe.
