IBM Z10 EC - Manual (Page 4)

Just-in-time deployment of IT resources
Infrastructures must be more fl exible 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 confi guration
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 capac-
ity or for testing new applications. Capacity Backup
Upgrade (CBU) can help provide reserved emergency
backup capacity for all processor confi gurations.
An additional 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.
By having fl exible and dynamic confi guration defi nitions,
when capacity is needed, activation of any portion of an
offering can be done (for example activation of just two
CBUs out of a defi nition that has four CBUs is accept-
able). And if the defi nition doesn’t have enough resources
defi ned, an order can easily be processed to increase the
capacity (so if four CBUs aren’t enough it can be redefi ned
to be six CBUs) as long as enough server infrastructure is
available to meet maximum needs.
All activations can be done without having to interact with
IBM—when it is determined that capacity is required, no
passwords or phone connections are necessary. As long
as the total z10 EC can support the maximums that are
defi ned, then they can be made available.
With the z10 EC, it is now possible to add permanent
capacity while a temporary capacity is currently activated,
without having to return fi rst to the original confi guration.
The activation of On/Off CoD on z10 EC can be simplifi ed
or automated by using z/OS Capacity Provisioning (avail-
able with z/OS ® 1.9 and above). This capability enables the
monitoring of multiple systems based on Capacity Provi-
sioning and Workload Manager (WLM) defi nitions. When
the defi ned conditions are met, z/OS can suggest capacity
changes for manual activation from a z/OS console, or the
system can add or remove temporary capacity automati-
cally and without operator intervention.
Specialty engines offer an attractive alternative
The z10 EC continues the long history of providing inte-
grated technologies to optimize a variety of workloads. The
use of specialty engines can help users expand the use
of the mainframe for new workloads, while helping to lower
the cost of ownership. The IBM System z ® specialty engines
can run independently or complement each other. For
example, the zAAP and zIIP processors enable you to pur-
chase additional processing capacity exclusively for spe-
cifi c workloads, without affecting the MSU rating of the IBM
System z model designation. This means that adding a
specialty engine will not cause increased charges for IBM
System z software running on general purpose processors
in the server.
