IBM’s server for the on demand world
Customers of every size, and across every industry are looking for ways to make their businesses more productive and more resilient in the face of change and uncertainty. They need the ability to react to rapidly changing market conditions, manage risk, outpace their competitors with new capabilities, and deliver clear returns on investments.

Welcome to the on demand era – the next phase of e-business evolution. To meet the challenges of constant change, companies must go beyond simply integrating business processes. They must have the flexibility to provide products and services to customers on demand. But success in this environment takes a new approach to business – and a new kind of IT infrastructure to support it.

The IBM zSeries 990 (z990) delivers enriched functions for the on demand operating environment. zSeries is the enterprise class e-business server optimized for mixed workload integration, high transaction processing, and data serving for the on demand world. In implementing the z/Architecture™ with new technology solutions, zSeries is designed to facilitate IT and business transformation and reduce the stress of growing business-to-business, business-to-customer, and business-to-employee computing requirements. The zSeries represents an advanced generation of servers that feature enhanced performance, support for zSeries Parallel Sysplex® clustering, improved hardware management controls, open and industry standard technologies such as Linux and Java™ , and innovative functions to address infrastructure simplification and on demand business operations.

The z990 is designed to provide a balanced system and improved price/performance. From processor storage to the system's I/O and network channels, end-to-end bandwidth is designed to deliver data where and when it is needed. With a choice of four models, the largest z990 can be configured with up to three times the processing power, four times the memory, four times the HiperSockets™, up to four times the number of ESCON® channels, up to two and one half times more FICON™ and up to twice the number external coupling links of an IBM eServer zSeries 900 (z900) Model 216 server. Each model adds to the system's total resources – so you can have the ability to scale up with z/OS and reliably handle your most critical business transactions.

Powerful
zSeries is based on the 64-bit z/Architecture, which is designed to reduce memory and storage bottlenecks and can automatically direct resources to priority workloads through Intelligent Resource Director (IRD).

With the superscalar microprocessor and the CMOS 9S-SOI technology, the z990 is designed to further extend and integrate key platform strengths such as dynamic flexible partitioning and resource management for mixed and unpredictable workloads. zSeries provides scalability, high availability and Quality of Service.

The z990 provides a significant increase in system scalability and opportunity for server consolidation by providing a multi-book system structure that supports the configuration of one to four books.

Each book is comprised of a MultiChip Module (MCM), memory cards – that can support up to 64 GB of memory per book – and high performance Self-Timed Interconnects.

To support the highly scalable multi-book system design, the Channel SubSystem (CSS) has been enhanced with Logical Channel SubSystems (LCSSs) which provides the capability to install up to 1024 ESCON channels across three I/O cages. With Spanned Channel support, HiperSockets, ICB, ISC-3, OSA-Express, OSA-Express2, FICON Express and FICON Express2 can be shared across LCSS for additional flexibility. High-speed interconnects for TCP/IP communication, known as HiperSockets, let TCP/IP traffic travel among partitions and virtual servers at memory speed, rather than network speed.

Continuing enhancements to the Open Systems Adapters provide improved throughput, enhanced virtualization with up to 4 times the supported TCP/IP connections, Large Send TCP Segmentation offload, concurrent LIC updates, a 10 Gigabit Ethernet feature and the capability to perform like a Layer 2 type device providing the capability of being protocol or Layer 3 independent.

FICON Express2 features can provide improved throughput, support for up to four FICON channels, support for up to 2 Gigabits per second high speed attachment of traditional disk and tape storage, connectivity to SCSI based open storage via Linux on zSeries, and availability enhancements with FICON Purge Path Extended. Additionally, with FICON Express and FICON Express2, FCP LUN Access Control is previewed and is designed to enhance secuirty and resource sharing on SCSI storage controllers and devices.

OSA-Express Integrated Console Controller (OSA-ICC) support can be enabled using a port on the 1000BASE-T Ethernet feature. Each OSA-ICC port is designed to support up to 120 console session connections for z990 Initial Program Load and z/OS, z/VM, VSE/ESA and TPF operational consoles. OSA-ICC also supports spanned channels.

The zSeries Application Assist Processor (zAAP) is an attractively priced specialized processing unit that provides a strategic z/OS Java execution environment for customers who desire the powerful integration advantages and traditional qualities of service of the zSeries platform.
zAAPs enable you to effectively integrate and run e-business Java workloads on the same server as your database, helping to simplify and reduce the infrastructure required for Web applications while helping to lower your overall total cost of ownership.

zAAPs are designed to operate asynchronously with the general purpose Central Processors (CPs) to execute Java programming under control of the IBM Java Virtual Machine (JVM). This can help reduce the demands and capacity requirements on general purpose CPs which may then be available for reallocation to other zSeries workloads. The amount of general purpose CP savings may vary based on the amount of Java application code executed by zAAP(s). And best of all, IBM JVM processing cycles can be executed on the configured zAAPs with no anticipated modifications to the Java application(s). Execution of the JVM processing cycles on a zAAP is a function of the IBM Software Developer's Kit (SDK) for z/OS Java 2 Technology Edition, z/OS 1.6 (or z/OS.e 1.6) and the innovative Processor Resource/Systems Manager™ (PR/SM).

Essentially, zAAPs allow customers to purchase additional processing power exclusively for z/OS Java application execution without affecting the total MSU rating or machine model designation. Conceptually, zAAPs are very similar to a System Assist Processor (SAP); they cannot execute an Initial Program Load and only assist the general purpose CPs for the execution of Java programming. Moreover, IBM does not impose software charges on zAAP capacity. Additional IBM software charges apply only when additional general purpose CP capacity is used.

Intelligent Improving capacity, bandwidth and performance is good but managing these resources to help meet your business goals is even better. The z990 can help you save time and money with its self-optimizing and autonomic capabilities.

Intelligent Resource Director (IRD) is a key feature of the z/Architecture. Together, Parallel Sysplex technology and IRD are designed to provide the flexibility and responsiveness required by on demand business workloads. These capabilities can significantly help minimize the complexities inherent in broadly distributed IT infrastructures and can help lower your total cost of ownership.

The z990 extends the power and versatility of z/OS's innovative Workload Manager from the edge of a network to the heart of the data. Business priorities are used for real time prioritization of network and I/O requests when combined with Cisco technology and through the IBM TotalStorage® 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.
