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
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.
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
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.
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
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.
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.
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.
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.
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.
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).
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.
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.
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.
