Smoothing the path
The systems management functions
and features of the z890 provide
incredibly robust control and
automation as well as exceptional
service-ability and availability. For
example, Intelligent Resource
Director (IRD) extends the classic
strengths of I/O priority queuing by
prioritising requests across the
channels of the z890 to move to the
workloads which require additional
connectivity via Dynamic Channel
Path Management. It can dynamically
balance CP resources across LPARs
according to business goals.
z/OS can provide an approach for
installing and configuring products: a
managed system infrastructure. This
approach, when employed, goes a
step beyond Web-based wizards by
furnishing a step-by-step installation
guide and automated system
updates. For example, Managed
Systems Infrastructure for Setup can
establish a Parallel Sysplex cluster
quickly and easily by transparently
creating the policies, parmlib
specifications and initialisation
parameters necessary to configure a
basic Parallel Sysplex environment.
The new frontier
What does the on demand era mean
for your medium-sized enterprise?
It means being able to sense and
respond to change. It means
managing risk while lowering costs.
It means greater control and
transparency with less complicated
management. And it means
maintaining a flexible IT infrastructure.
With its combination of flexible design
and advanced mainframe technology,
the IBM
^ zSeries 890 can
help your company simplify its
infrastructure and remain flexible. It
can offer your business extremely
granular growth options, along with
the power and flexibility that comes
with technology that can be
configured for general purpose
workload processing (CPs), Linux
workloads (IFL), Parallel Sysplex ICF,
as well as specialty assist processing
for I/O (SAPs) and Java-based
applications (zAAPs). All of this
comes with the world-class
mainframe qualities of service
(e.g., high availability, scalability
and security) found on the z990 –
IBM’s cornerstone e-business on
demand server. The z890 is designed
to provide a growth-focused
mainframe with advanced on demand
capabilities at a size and cost that fits
your business.
