IBM z/OS - Manual (Page 4)

The variable data center needs to be able to respond to
the ever-changing demands that occur when you sup-
port multiple diverse workloads as a single entity. It must
respond to maintain the quality of service required and
the cost of utilizing the resources must refl ect the chang-
ing environment. The zSeries Intelligent Resource Director
(IRD), which combines three key zSeries technologies,
z/OS ® Workload Manager (WLM), Logical Partitioning and
Parallel Sysplex ® technology, helps ensure that your most
important workloads get the resources they need and con-
stantly manages the resources according to the changing
priorities of the business. With Workload License Charges
(WLC), as the resources required by different applications,
middleware and operating systems change over time,
the software costs change to refl ect this. In addition, new
virtual Linux servers can be added in just minutes with
zSeries virtualization technology to respond rapidly
to huge increases in user activity.
The fl exible data center must be adaptable to support
change and ease integration. This is achieved through
a combination of open and industry standards along
with the adaptability to direct resources where they are
required. The zSeries, along with other IBM servers, has
been investing in standards for years. Key is the support
for Linux, but let’s not forget Java ™ and XML and industry
standard technologies, such as FCP, Ethernet and SCSI.
Finally the on demand data center must be designed to be
resilient. The zSeries has been renowned for reliability and
availability. The zSeries platform will help protect against
both scheduled and unscheduled outages, and GDPS ®
enables protection from loss of complete sites.
The New zSeries from IBM – Impressive Investment -
Unprecedented Performance
IBM’s ongoing investment in zSeries technology has pro-
duced a re-invention of the zSeries server — the z990. The
z990 makes the mainframe platform more relevant to cur-
rent business success than ever before. Developed at an
investment in excess of $1 billion, the new z990 introduces
a host of new benefi ts to meet today’s on demand business.
The major difference is the innovative book structure of the
z990. This new packaging of processors, memory and I/O
connections allows you to add incremental capacity to a
zSeries server as you need it. This makes the z990 a fl ex-
ible and cost-effective zSeries server to date.
IBM’s investment in zSeries doesn’t stop here. To solidify
the commitment to zSeries, IBM introduces the “Mainframe
Charter” that provides a framework for future investment
and a statement of IBM’s dedication to deliver ongoing
value to zSeries customers in their transformation to on
demand business.
