It may sound revolutionary, but it’s really quite simple. In
the highly unpredictable world of On Demand business,
you should get what you need, when you need it. And you
should pay for only what you use. Radical? Not to IBM. It’s
the basic principle underlying IBM capacity on demand for
the IBM System z10.
Changes have been made to enhance the Capacity on
Demand (CoD) experience for System z10 EC customers:
• The number of temporary records that can be installed
on the Central Processor Complex (CPC) has increased
from four to eight.
• Resource tokens are now available for On/Off CoD.
The z10 EC also introduces a architectural approach for
temporary offerings that can change the thinking about on
demand capacity. One or more fl exible confi guration defi ni-
tions can be used to solve multiple temporary situations and
multiple capacity confi gurations can be active at once (for
example, activation of just two CBUs out of a defi nition that
has four CBUs is acceptable). This means that On/Off CoD
can be active and up to seven other offerings can be active
simultaneously. Tokens can be purchased for On/Off CoD
so hardware activations can be prepaid.
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.
Capacity on Demand – Temporary Capacity:
The set of contract documents which support the various
Capacity on Demand offerings available for z10 EC has
been completely refreshed. While customers with exist-
ing contracts for Capacity Back Up (CBU) and Customer
Initiated Upgrade (CIU) – On/Off Capacity on Demand
(On/Off CoD) may carry those contracts forward to z10 EC
machines, new CoD capability and offerings for z10 EC is
only supported by this new contract set.
The new contract set is structured in a modular, hierarchi-
cal approach. This new approach will eliminate redundant
terms between contract documents, simplifying the con-
tracts for our customers and IBM.
Just-in-time deployment of System z10 EC Capacity on
Demand (CoD) is a radical departure from previous System
z and zSeries servers. This new architecture allows:
• Up to eight temporary records to be installed on the
CPC and active at any given time
• Up to 200 temporary records to be staged on the SE
• Variability in the amount of resources that can be acti-
vated per record
• The ability to control and update records independent
of each other
• Improved query functions to monitor the state of each
record
• The ability to add capabilities to individual records con-
currently, eliminating the need for constant ordering of
new temporary records for different user scenarios
• Permanent LIC-CC upgrades to be performed while
temporary resources are active
These capabilities allow you to access and manage
processing capacity on a temporary basis, providing
increased fl exibility for on demand environments. The CoD
offerings are built from a common Licensed Internal Code
– Confi guration Code (LIC-CC) record structure. These
Temporary Entitlement Records (TERs) contain the infor-
mation necessary to control which type of resource can be
accessed and to what extent, how many times and for how
long, and under what condition – test or real workload.
Use of this information gives the different offerings their
personality.
