capacity not being used by z/OS LPARs to be allocated
to a z/VM LPAR hosting z/OS guests running Java and
DB2 workloads. zAAPs and zIIPs cost less than stan-

dard CPs, so this support might enable you to avoid
purchasing additional CPs, thereby helping to reduce
your costs both for additional hardware and for software
licensing fees.
The System z10 EC offers the Integrated Facility for Linux
(IFL) to support Linux and open standards. Linux brings
a wealth of available applications that can be run in a real
or virtual environment under the z10 EC. The System z
platform, with z/VM, provides users with the ability to scale
out, deploying hundreds to thousands of virtual Linux serv-
ers in one CEC footprint. The z/VSE
integration between z/VSE and Linux on System z to help
customers integrate timely production z/VSE data into new
Linux applications, such as data warehouse environments
built upon a DB2 data server. The mainframe offers a com-
prehensive suite of characteristics and features such as
availability, scalability, clustering, systems management,
HiperSockets and security to enable and support new and
existing environments.
Numerical computing on the chip
Integrated on the z10 EC processor unit is a Hardware
Decimal Floating Point unit to accelerate decimal floating
point transactions. This function is designed to markedly
improve performance for decimal floating point operations
which offer increased precision compared to binary floating
point operations. This is expected to be particularly useful
for the calculations involved in many financial transactions.
Decimal calculations are often used in financial applica-
tions and those done using other floating point facilities
have typically been performed by software through the
use of libraries. With a hardware decimal floating point
unit, some of these calculations may be done directly and
accelerated.
Liberating your assets with System z
Enterprises have millions of dollars worth of mainframe
assets and core business applications that support the
heart of the business. The convergence of service oriented
architecture (SOA) and mainframe technologies can help
liberate these core business assets by making it easier to
enrich, modernize, extend and reuse them well beyond
their original scope of design. The z10 EC, along with the
®
inherent strengths and capabilities of a z/OS environment,
provides an excellent platform for being an enterprise hub.

Evolving for your business
The z10 EC is the next step in the evolution of the System z
mainframe, fulfilling our promise to deliver technology
improvements in areas that the mainframe excels in—
energy efficiency, scalability, virtualization, security and
availability. The redesigned processor chip helps the z10
EC make high performance compute-intensive processing
a reality. Flexibility and control over capacity gives IT the
upper edge over planned or unforeseen demands. And
new technologies can benefit from the inherit strengths of
the mainframe. This evolving technology delivers a com-
pelling case for the future to run on System z.
