point. That’s not so bad, considering
the z990 is IBM’s most sophisticated
mainframe, with world-class
scalability, virtualisation, automation,
security and reliability.
The new IBM
^ zAAP,
planned to be available on the z890
and z990 servers, is an attractively
priced specialised processing unit
that provides an economical Java
execution environment for customers
who desire the traditional qualities
of service and the integration
advantages of the zSeries platform.
zAAPs are designed to assist and
operate asynchronously with the
central processors to execute Java
programming under control of the
IBM Java Virtual Machine (JVM). This
can help reduce the demands and
capacity requirements on central
processors which may then be
available for reallocation to other
zSeries workloads. The amount of
central processor savings may vary
based on the amount of Java
application executed by zAAPs, and
thereby may contribute to lowering
the overall cost of computing for z/OS
Java technology-based applications.
Best of all, IBM JVM processing
cycles can be executed on the
configured zAAPs with no anticipated
modifications to the Java
application(s).
Another new feature for both the z890
and the z990 is the OSA-Integrated
Console Controller (OSA-ICC), which
offers system console (IPL) and
operations support for multiple logical
partitions (LPARs). The OSA-ICC
enables local and remote user
console session capability, as well as
encrypted remote connection for
configuration changes. Use of the
OSA-ICC can positively impact the
ongoing costs of running your
system by eliminating the requirement
for an external controller for console
support.
The zSeries is the enterprise class
e-business server optimised for
integration, transactions and data of
the next generation e-business world.
In implementing the z/Architecture
features with new technology
solutions, zSeries models are
designed to help facilitate the IT
business transformation and reduce
the stress of Business to Business
(B2B) and Business to Customer
(B2C) growth pressure. The zSeries
represents an advanced generation
Granular growth options
When it comes to growth, the z890
offers extreme granularity. The range
of capacities for the z890 has
increased from the processor on its
predecessor, the z800 – options for
low capacity have gotten lower and
those for high capacity have gotten
higher. What does that mean to your
business? It means you can start at
the capacity level you need to simplify
your IT infrastructure, then add
additional capacity to meet your
changing needs as you grow.
Built on z990 technology
Built on the powerhouse function of
the z990, the z890 offers many of the
features and functions of the z990 at a
considerably lower capacity entry
and specialised assist processing
with zAAPs delivers a newly designed
environment for running Java
technology-based applications along
with z/OS on the mainframe. Most
importantly, the z890 gives your
business many of the same
availability, scalability and security
features of the z990 – IBM’s
cornerstone e-business on demand
server.
The z890 can provide the power and
flexibility that seemed out of reach, in
a size that’s right for your IT world.
