> 9 September 2003 Update
This update includes:
- New EWLC pricing metric for z800s.
- An Example Demonstrating Lower z/OS Monthly Charges
due to IBM's Mainframe Charter Initiatives.
- A graphical analysis showing the pricing evolution of z/OS below
- The LPAR-PRICING-L discussion list is also
now available specifically for LPAR Pricing topics.
9th, IBM announced LPAR Pricing for z800s with Entry Workload
License Charge (EWLC). Similar to Variable Workload License
Charge (VWLC) for the z900 and z990 EWLC will use the combined
simultaneous 4-hour rolling average of the LPARs a product executes
in as the basis for the product's charge each month. This provides
more granularity than zELC which was based on the hardware capacity,
regardless of the actually utilization of the machine. The chart
at the right shows the monthly charge for z/OS on the various
z800 models, click here for a larger
image and more information. Once you choose EWLC you cannot
go back to zELC if you did the analysis wrong!
|Last month on 22Aug2003,
IBM introduced their Mainframe
Charter. (It was the subject of the August
update.) One initiative of the charter discussed lower monthly
charges for simultaneous 4-hour rolling averages less than 315
MSUs. A second initiative was the “resizing” of
the z990 models. The chart at the
right shows the impact of both these changes, click here
for a larger image and more information.
|Another view of the z/OS Pricing Evolution
is shown by examining the range from 1 to 375 MSUs. This highlights
the lowering of the entry point for Variable WLC to 3 MSUs,
as well as the mainframe charter related z/OS "price per
MSU" changes below 315 MSUs. Click here

discussion list is for discussing issues and questions
about LPAR Pricing for zSeries machines. IBM's
Workload License Charge is available for z900s,
z990s, and z800s. IBM's new Entry Workload License
Charge is available for z800s only. Related topics
of other pricing metrics are welcome, as well
as issues related to software asset management.
