IBM eServer zSeries 900 Servers

zSeries 800 zSeries 890 zSeries 900 zSeries 990
  • Balanced system design enables optimal use of system resources in dynamic e-business environments

  • Expanded range of models provides even greater scalability and performance

  • Linux® for zSeries™ supports the new 64-bit z/Architecture™ and extends choice in application flexibility

  • Self-managing… simplicity in an otherwise complex world

IBM extends server leadership Complexity is a way of life for businesses today. An average business must contend with five different architectures in its e-business infrastructure. The challenge customers face is how to manage all of these resources effectively while transforming their infrastructures. Compounding the problem is the projected shortfall of IT skills and the significant growth of the Internet.

This may sound like a daunting task, but IBM® is designing its IBM eServer™ product line to be self-managing so customers can concentrate on their business needs. At the core of many infrastructures is the IBM eServer zSeries 900 (z900) powered by z/OS™. Specifically designed to handle the massive growth in transactional and data demands of the e-business world, z900 and z/OS intelligently manage a multitude of diverse workloads within a single server, out to the network and to data, all according to each customer's business priorities.

z900 servers now offer 42 air-cooled models, ranging from 1- to 16-way, including 16 2xx models offering up to approximately 20 percent improvement over the original 1xx models. These servers can be configured in numerous ways to offer outstanding flexibility for speedy deployment of e-business solutions. Each z900 can operate independently or as part of a Parallel Sysplex® cluster of servers. In addition to supporting z/OS, the z900 can host tens to hundreds of Linux images running major commercial applications and open source applications using z/VM™.

The IBM eServer product line is backed by a comprehensive suite of offerings and resources that provide value at every stage of IT implementation. These tools can help customers test possible solutions, obtain financing, 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 Services experts can help with business and IT consulting, business transformation and total systems management services as well as customized e-business solutions.

Powerful z900 servers are based on the z/Architecture, which enables applications to have large memory and can help eliminate bottlenecks associated with the lack of addressable memory. It supports a new standard of performance and integration by expanding on the balanced system approach of the IBM S/390® architecture.

As the connected world becomes increasingly demanding, servers will need to provide faster data access and continuous data availability, as well as improved flexibility and efficiency of data — all with lower cost of ownership. zSeries I/O connectivity and networking features can help customers attain these goals. Additions to CPU, memory and I/O capacity enables z900 to respond quickly to workload spikes. A robust I/O subsystem complements the great number of processors and large main memory. Native FICON and Fibre Channel Protocol (FCP) devices provide improved performance, greater configuration flexibility, and lower total cost through channel consolidations. Furthermore, IBM's intent to provide FICON cascaded director support will mean improved fiber infrastructure utilization and additional cost savings.

High speed interconnects for TCP/IP communication, known as HiperSockets™, let TCP/IP traffic travel between partitions at memory speed, rather than network speed. A new, higher performing Gigabit Ethernet feature is one of the first in the industry capable of achieving line speed: one gigabit per second. IPv6 support enables more addresses to allow for larger configurations. The result is ultra high speed communications within the server, between servers, to devices and out to users, thereby allowing greater integration between traditional and Web applications for maximum e-business effectiveness.

Intelligent Improving capacity, bandwidth, and performance is good — but managing these resources to meet your business goals is even better. Save time and money with zSeries self-optimizing and self-healing functionality.

zSeries servers automatically direct resources to priority work through Intelligent Resource Director (IRD). The zSeries IRD combines the strengths of three key technologies: Workload Manager, Logical Partitioning and Parallel Sysplex clustering.

This powerful combination of z900 servers and z/OS provides the ability to intelligently self manage numerous operating system images executing on a single server, as a single compute resource, with dynamic workload management and physical resource balancing across logical partitions. In short, the system can dynamically allocate processors, channel paths and channel-andcontroller work across multiple virtual servers to ensure that the unpredictable needs of e-business workloads can be managed according to business priorities.

The zSeries and z/OS extend the power of Workload Manager from the edge of a network to the heart of data. Business priorities are used for realtime prioritization of network and I/O requests when combined with Cisco technology and through the IBM Enterprise Storage Server™. The Sysplex Distributor function of z/OS provides intelligent load balancing of TCP/IP traffic across a Parallel Sysplex cluster. Dynamic Virtual Internet Protocol Addressing (VIPA) support extends the workload distribution and availability features of Parallel Sysplex technology to the TCP/IP network.
