System z On/Off Capacity on Demand

  
Pricing MLC zIPLA Sub-Capacity Sysplex Reference

On/Off Capacity on Demand (CoD) from IBM allows customer to enable and disable hardware engines to meet temporary peak business needs. On the System z platform, this hardware offering is available exclusively on the z10 EC, z10 BC, z9 EC, z9 BC, z990 and z890 servers. Charges related to both hardware and software are tied to the duration of the temporary enablement and the capacity enabled.


Daily On/Off Capacity on Demand (CoD) Software Charges
IBM offers daily software charges to complement our On/Off CoD server offering. In a System z environment, the daily On/Off CoD charges will apply to eligible products running on the System z server where customers activate the On/Off CoD server offering, to enable temporary engines.

Daily On/Off CoD software charges apply to select System z software products, licensed under the International Product License Agreement (IPLA). IPLA software generally describes a category of IBM software products with a license fee at the time of purchase and an annual maintenance charge, known as Subscription & Support.

When ordering a System z server with On/Off CoD capability, customers sign the "Customer Initiated Upgrade (CIU) and IBM eServer On/Off CoD - Attachment" (Z125-6611) which requires customers to provide IBM with a list of the program numbers and descriptions of the IPLA programs (and their parent programs, if applicable) which are licensed on that server.

For On/Off CoD on System z, software charges are calculated based upon the amount of temporary capacity (e.g. MSUs) and the duration the temporary capacity is available (in days). Here is an example:

  • Amount of temporary capacity will be determined by evaluating the difference between the customer's permanent z990 capacity compared with the customer's (permanent + temporary) z990 capacity. For example, if a customer has a 6 engine z990 server (352 MSUs) and adds two engines, making it temporarily an 8 engine z990 server (448 MSUs), the temporary capacity will be 448 MSUs - 352 MSUs for a total of 96 MSUs

  • Duration will be judged in days, where a day is any contiguous 24-hour period. For example, an activation period that begins on September 15th at 1pm and lasts until September 16th at 3pm is 26 hours, which counts as two days in the context of On/Off CoD.

  • Most software products with On/Off CoD charges have published prices in terms per "MSU-day" (though some products have On/Off CoD charges in terms per "Processor-day"). To determine the total number of MSU-days, multiply the amount of temporary capacity by the number of days. In the example, above, this would be 96 MSUs multiplied by 2 days for a total of 192 MSU-days.

As of the 27 April 2006 announcement (PDF, 85KB), customers may apply excess entitled license capacity for individual products towards On/Off CoD events, thus potentially avoiding daily On/Off CoD software charges on those products.

  • For example, if a customer has installed one z9 BC capacity setting S04 (111 MSUs) and he wants to use On/Off CoD to add temporary capacity, he could temporarily upgrade to a z9 BC capacity setting T04 (124 MSUs). He plans to keep this temporary capacity installed for less than 24 hours, which would result in 13 MSU-days. The 13 MSU-days result is calculated by multiplying one day (one 24 hour period) times the amount of additional capacity (111 MSUs increasing to 124 MSUs).
  • If a daily On/Off CoD eligible program such as WebSphere® Application Server executes on this server, the customer would previously have had to pay a daily On/Off CoD charge of 13 MSU-days for WebSphere Application Server. Now, under the new terms, if the customer has an excess entitled license capacity for WebSphere Application Server, and his total entitled license capacity is large enough to support a server with 124 MSUs, then he will not incur any On/Off CoD charges for WebSphere Application Server for this On/Off CoD event. Note: These calculations are done individually for each product since a machine may have multiple IPLA products for which the customer has excess entitlements while other products do not.
  • Customers who are interested in taking advantage of these new terms must sign the "Amendment for On/Off CoD for Software Charges" (Z125-7391). Customers must explicitly request that IBM apply any excess entitlements, and they must inform IBM of any updates to their IPLA product(s) usage on all their machines. All requests must be sent by email to the appropriate email contact address.
  • Since the calculations of Daily On/Off CoD charges and determination of excess entitlements are done each month covering all On/Off CoD events which happened the previous month, excess IPLA entitlements will be taken into account in each subsequent month as long as they exist.

Customers may choose to have their IBM Business Partner perform the invoicing of Daily On/Off CoD charges instead of being invoiced directly by IBM. If the IBM Business Partner agrees to perform this invoicing, the customer and the IBM Business Partner must notify IBM of this arrangement by the end of the month during which On/Off CoD was used by sending an email to the appropriate email contact address.


On/Off Capacity on Demand Impact on Monthly Software Charges

The On/Off CoD Offering only encompasses hardware and IPLA software. In other words, it provides a daily fee for items which a customer would otherwise have had to purchase permanently. The On/Off CoD Offering does not offer any special terms for monthly license charge (MLC) software. Hence, MLC under OOCoD is considered "business as usual".

Here's an examination of the On/Off CoD impacts on the MLC metrics:

  • for Parallel Sysplex License Charges, Full-Capacity Workload License Charges, Full-Capacity Entry Workload License Charges - IBM business rules state that a hardware upgrade must last a minimum of 30 days. So, if a customer adds an On/Off CoD engine on March 12th then IBM will consider that the downgrade occurs on April 12th, from an MLC perspective. In this example, March MLC is not affected due to Full-Month Billing. In this example, April MLC is charged at (permanent capacity + one temporary engine) due to Full-Month Billing.
  • for Usage License Charges, Sub-Capacity Workload License Charges, Sub-Capacity Entry Workload License Charges - IBM business rules state that customers must collect required SMF records and send the required Sub-Capacity report by the deadline (monthly Sub-Capacity Report for Sub-Cap pricing and yearly IFAURP Report for ULC). There is no manual adjustment to the reports permitted if a temporary engine is added under On/Off CoD. Therefore, an On/Off CoD event that occurs in March may a) affect May's billing under Sub-Capacity pricing or b) affect next year's billing under Usage License Charges -- assuming that the Usage License Charges reporting window is set to the calendar year.
