The z890 server, the latest addition to the zSeries family,
takes advantage of the design enhancements and new
1
technology of the z990 in a package that helps deliver
1
excellent price/performance for those customers requiring
a lower capacity entry point than that offered by the z990.
With a new superscalar microprocessor and the CMOS 9S-
SOI technology, the z890 is designed to further extend and
integrate key platform characteristics such as dynamic
fl exible partitioning and resource management in mixed
and unpredictable workload environments, providing tra-
ditional zSeries Quality of Service to emerging e-business
applications such as WebSphere
The IBM ^ zSeries Application Assist Processor
(zAAP), available on the IBM ^ zSeries 990 (z990)
and zSeries 890 (z890) servers, is an attractively priced
specialized processing unit that provides strategic z/OS
Java execution environment for customers who desire the
powerful integration advantages and traditional Qualities
of Service of the zSeries platform.
When confi gured with general purpose Central
Processors (CPs) within logical partitions running z/OS,
zAAPs can help you to extend the value of your existing
zSeries investments and strategically integrate and run
