Sub-Capacity Possible Benefits
 Grow Hardware Capacity Independently of Software Capacity
– Pay for software only based on the LPAR(s) where the software executes
– Grow software with 1 MSU level of granularity
– Spike into "spare" capacity without software charges
– Manage utilization without having to turn engines on and off
 Flexibility to Pay for What you Need each Month
– In the case of ELA, your monthly payments are fixed and your actual sub-capacity
monthly software inventory value is compared against your MLC cap
 Pay on Average Utilization, not Maximum Utilization
– Highest observed rolling 4-hour average utilization across a month
– Sub-Capacity Reporting Tool manages measurement/reporting

z/VSE V4 – New Pricing Metric & Sub-Capacity!
 z/VSE V4:
– z/Architecture (64-bit) mode only
z10 EC, z10 BC, z9 EC, z9 BC, z990, z890, z900, z800
– Up to 8 GB real processor storage
 z/VSE Price/Performance Through New Pricing Metric
– Midrange Workload License Charges – MWLC
Low full capacity price points
Sub-capacity option
Available on System z10 and System z9 servers only (z10 BC, z10 EC,
z9 BC and z9 EC)
 Additional Price/Performance Through Sub-Capacity
– Some hardware footprint consolidations more attractive now
 MWLC requires current servers (z10 BC, z10 EC / z9 EC / z9 BC) and
z/VSE V4
– Presence of z/VSE V3 or VSE/ESA forces full-capacity pricing
* z9 BC A01 is priced zELC, not MWLC

– Java work ONLY directed to zAAPs by z/OS 1.6+
 Can help lower cost of computing for Java technology-based
application servers
– Attractively priced on z10 EC, z10 BC, z9 EC, z9 BC, z990, and
z890.
– No IBM software charges on zAAPs
 Required Elements
– z/OS 1.8* or higher
– zAAP hardware feature
– Java SDK 1.4.1
* Originally supported with z/OS1.6 which is no longer a supported release
18

IBM System z Integrated Information Processor
(IBM zIIP)
 Specialty engine for the System z9 and System z10 server designed to help:
– Customers integrate data across the enterprise
– Improve resource optimization and lower the cost of ownership for eligible data serving workloads
 z/OS manages and directs work between the general purpose processor and the zIIP
– Number of zIIPs per server not to exceed number of standard processors
– No changes anticipated to DB2 for z/OS V8 applications
 DB2 for z/OS V8 was the first IBM exploiter of the zIIP with
– z10 EC, z9 EC and z9 BC
– z/OS 1.8 or later (Available with z/OS 1.6 which is no longer a supported release)
– DB2 for z/OS V8 or later
– Additional zIIP function with XML

System z Top Gun
zNALC – a great value!
System z New Application License Charges (zNALC) for z/OS
Attractive pricing for z/OS operating system for qualified new workloads on the
System z platform
Customers looking to add new applications to System z as well as existing NALC
and z/OS.e customers will be interested in zNALC.
zNALC provides:
 Single Qualified New Workload pricing metric across System z product line
 LPAR-level granularity
– Sub-capacity announced and supported – no need for full machine dedicated to new
workload
 zNALC ‘Qualified New Workload’ Criteria replaces NALC Fixed Application List
– A wider choice of workloads
 Improved z/OS pricing
– Incremental Price/Performance improvements including Parallel Sysplex® Aggregation
 No separate z/OS product or product number
24
© 2008,2009 IBM Corporation
System z Top Gun
zNALC expands the definition of ‘qualified new
workload’
 zNALC can provide more choice of qualifying applications*
 zNALC provides a definition of Qualified Applications:
– Qualifies a range of commercially available UNIX and Microsoft Windows
applications
– Qualifies a range of enterprise application data serving workloads
– Qualifies a range of Java™ language business applications running under
WebSphere Application Server
– See the zNALC announcement letter for terms, conditions, and details
 NALC was applicable only to a short list of select applications
 z/OS.e disables or disallows certain products, applications, and
workloads
* zNALC is available only on LPARs dedicated to a qualified new workload application. In general, qualified applications are those that IBM
considers 'new workload', such as Java language business applications running under WebSphere Application Server, Lotus ® Domino™,
SAP, PeopleSoft, and Siebel among others.

Learning Points - System z Software Pricing


System z Monthly License Charges (MLC) pricing is typically used for DB2, CICS, IMS,
MQSeries, COBOL compilers, PL/1 compilers, Domino, z/OS, z/VSE.

z/OS.e disables or disallows certain products, applications, and workloads (such as IMS, CICS)
and supports z800/z890/z9 BC/z10 BC servers only.

zNALC replaces z/OSe and NALC for reduced z/OS pricing for qualified workloads across all
System z Servers..

Parallel Sysplex License Charges (PSLC) applies to qualified Parallel Sysplexes and
significantly lowers software prices by aggregating capacity across the entire qualified Parallel
Sysplex.

WLC Sub-Capacity Software pricing is determined by the processor capacity used during the
peak rolling four hour average for the LPAR(s) in which the software is running.
