Ibm System Z10 - IBM System z10 EC Reference Manual

IBM System z10 Enterprise Class (z10 EC) Overview
In today's world, IT is woven in to almost everything that a
business does and is consequently pivotal to a business.
Some of the key requirements today are the need to
maximize return on investments by deploying resources
designed to drive efficiencies and economies of scale,
managing growth through resources that can scale to
meet changing business demands, reducing risk by
reducing the threat of lost productivity through downtime
or security breaches, reduce complexity by reversing the
trend of server proliferation and enabling business innova-
tion by deploying resources that can help protect existing
investments while also enabling those new technologies
that enable business transformation.
The IBM System z10 Enterprise Class (z10
™
a world-class enterprise server designed to meet these
business needs. The z10 EC provides new levels of per-
formance and capacity for growth and large scale con-
solidation, improved security, resiliency and availability to
reduce risk, and introduces just in time resource deploy-
ment to help respond to changing business requirements.
As environmental concerns raise the focus on energy
consumption, the z10 EC is designed to reduce energy
usage and save floor space when used to consolidate x86
servers. Specialty engines continue to help users expand
the use of the mainframe for a broad set of applications,
while helping to lower the cost of ownership. The z10 EC is
at the core of the enhanced System z
ers technologies that businesses need today along with a
foundation to drive future business growth.
Just in time deployment of IT resources
Infrastructures must be more flexible to changing capacity
requirements and provide users with just-in-time deploy-
ment of resources. Having the 16 GB dedicated HSA on
the z10 EC means that some preplanning configuration
changes and associated outages may be avoided. IBM
Capacity Upgrade on Demand (CUoD) provides a perma-
nent increase in processing capacity that can be initiated
by the customer.
IBM On/Off Capacity on Demand (On/Off CoD) provides
temporary capacity needed for short-term spikes in
capacity or for testing new applications. Capacity Backup
Upgrade (CBU) can help provide reserved emergency
backup capacity for all processor configurations.

A new temporary capacity offering on the z10 EC is
Capacity for Planned Events (CPE), a variation on CBU.
If unallocated capacity is available in a server, it will allow
the maximum capacity available to be used for planned
events such as planned maintenance in a data center.
The z10 EC introduces a new architectural approach for
temporary offerings that can change the thinking about
on demand capacity. One or more flexible configuration
definitions can be used to solve multiple temporary situa-
tions and multiple capacity configurations can be active at
once. This means that On/Off CoD can be active and up to
three other offerings can be active simultaneously.

By having flexible and dynamic configuration definitions,
when capacity is needed, activation of any portion of an
offering can be done (for example activation of just two
CBUs out of a definition that has four CBUs is accept-
able). And if the definition doesn't have enough resources
defined, an order can easily be processed to increase the
capacity (so if four CBUs aren't enough it can be redefined
to be six CBUs) as long as enough server infrastructure is
available to meet maximum needs.
