IBM z/OS manual To huge increases in user activity, Tools for Managing e-business

The variable data center needs to be able to respond to the ever-changing demands that occur when you sup- port multiple diverse workloads as a single entity. It must respond to maintain the quality of service required and the cost of utilizing the resources must refl ect the chang- ing environment. The zSeries Intelligent Resource Director (IRD), which combines three key zSeries technologies, z/OS® Workload Manager (WLM), Logical Partitioning and Parallel Sysplex® technology, helps ensure that your most important workloads get the resources they need and con- stantly manages the resources according to the changing priorities of the business. With Workload License Charges (WLC), as the resources required by different applications, middleware and operating systems change over time, the software costs change to refl ect this. In addition, new virtual Linux servers can be added in just minutes with zSeries virtualization technology to respond rapidly

to huge increases in user activity.

The fl exible data center must be adaptable to support change and ease integration. This is achieved through a combination of open and industry standards along with the adaptability to direct resources where they are required. The zSeries, along with other IBM servers, has been investing in standards for years. Key is the support for Linux, but let’s not forget Javaand XML and industry standard technologies, such as FCP, Ethernet and SCSI.

Finally the on demand data center must be designed to be resilient. The zSeries has been renowned for reliability and availability. The zSeries platform will help protect against both scheduled and unscheduled outages, and GDPS® enables protection from loss of complete sites.

The New zSeries from IBM – Impressive Investment -

Unprecedented Performance

IBM’s ongoing investment in zSeries technology has pro- duced a re-invention of the zSeries server — the z990. The z990 makes the mainframe platform more relevant to cur- rent business success than ever before. Developed at an investment in excess of $1 billion, the new z990 introduces a host of new benefi ts to meet today’s on demand business.

The major difference is the innovative book structure of the z990. This new packaging of processors, memory and I/O connections allows you to add incremental capacity to a zSeries server as you need it. This makes the z990 a fl ex- ible and cost-effective zSeries server to date.

IBM’s investment in zSeries doesn’t stop here. To solidify the commitment to zSeries, IBM introduces the “Mainframe Charter” that provides a framework for future investment and a statement of IBM’s dedication to deliver ongoing value to zSeries customers in their transformation to on demand business.

Tools for Managing e-business

The IBM ^product line is backed by a compre- hensive suite of offerings and resources that provide value at every stage of IT implementation. These tools can help customers test possible solutions, obtain fi nancing, plan and implement applications and middleware, manage capacity and availability, improve performance and obtain technical support across the entire infrastructure. The result is an easier way to handle the complexities and rapid growth of e-business. In addition, IBM Global Ser- vices experts can help with business and IT consulting, business transformation and total systems management services, as well as customized e-business solutions.
