IBM Helps Take Windows to the Mainframe
EUC with HCI: Why It Matters
IBM has made good on its promise to deliver Windows integration with the IBM mainframe via the zEnterprise System.
When IBM introduced the zEnterprise in July 2010, the company also announced plans to deliver additional general-purpose blades for the IBM zEnterprise BladeCenter Extension including IBM System x-based blades running Linux in 2011. IBM also suggested it would support Windows, and in April 2011 it confirmed its plans to deliver Windows support on z/Enterprise.
IBM says this capability is a first of its kind and is a strategic, demand-driven move by Big Blue. As of Dec. 16, this new technology enabling IBM zEnterprise System users to integrate Windows applications into the mainframe environment will become available.
The new capability allows enterprises with multitier applications--for example, Windows applications connected to mainframe data--to be integrated and consolidated on the same system. In an interview with eWEEK, Greg Lotko, vice president of marketing for System z, said this bringing together of the mainframe and distributed computing worlds is designed to ease the cost and complexity of large corporate data centers and improve management of workloads spanning mainframe and distributed environments.
"We GA'd made the system generally available in the third quarter of 2010," Lotko said. "In Q4 of last year we put out the zEnterprise BladeCenter Extension with support for IBM Power7 blades running AIX and the IBM Smart Analytics Optimizer. In Q1 of 2011 we made the DataPower blades available. In Q2 clients asked for Windows so we listened to our clients and modified our plans and said we would deliver it by the end of the year. In Q3 we delivered Linux integration, and in Q4 we're delivering Windows."
By bringing Windows and the mainframe together, IBM is helping clients innovate more freely in multiple environments across z/OS, Linux and Unix, and now Windows.
IBM's System z support for Windows means that mainframe users can gain more choice in choosing the best platform for a particular application from ERP to business analytics to transaction processing. Users also can have their front-end Windows applications integrate with applications or data on the mainframe. And they can consolidate more workloads onto the mainframe as part of their efforts to maximize technology investments. The financial impact of consolidation onto System z can be substantial, with savings of up to 70 percent in total cost of ownership compared with distributed platforms, IBM officials said.
"The effort we had to do here was largely a testing effort," Lotko said, indicating that the core technology already was in place but the new integration had to be tested.
Lotko said the new technology provides centralized management--the new capability of consolidating and centralizing management of Windows applications on x86-based IBM System x servers will be available for either of the zEnterprise systems: the z196 or z114, he said.
Through a hybrid computing approach, IBM System x blades and System x applications can be installed in a zEnterprise. No changes are required for the application, and integration and management of blades and applications are handled by the zEnterprise Unified Resource Manager, via a single console, IBM officials said. The benefit is that the application servers can be physically and logically close to the data running on the mainframe.
The hybrid capability already had been available for managing IBM Power-based workloads with operating system support for AIX- and System x-based workloads with Linux as well as a business analytics solution the IBM Data Analytics Accelerator and a multifunctional appliance for System z IBM Websphere DataPower XI50 for zEnterprise. With these capabilities, IBM's zEnterprise System is pushing a "system of systems" approach that allows disparate workloads spread across multiple systems to be managed as a single environment.
