Adding my 2 cents worth: Within the Capcity on Demand (CoD) offering for Z, there are a number of options available for different types of situations. Some have already been mentioned. A couple of useful docs:
1. IBM Redbook. Capacity on Demand SG24-7504. Almost 10 years old. Apart from some 'enhancements' to the offering (mainly to do with pricing/maintenance charges and entitlement to carry foward 'options' when upgrading to a newer Z system) and adding of the System Recovery Boost (SRB) option for the z15, the main content is still relevant. 2. zSystem Capacity On Demand User’s Guide - SC28-6943 All the CoD options i.e. CBU, CIU, CPE, On/Off CoD and SRB have T&Cs. Key point about the contracts is that some may be localised for an individual country. In addition, different CoD records have different time limits/expiration dates. Some additional points: 1. Its a given that to activate the additional capacity, the physical resource is already available in the system. 2. CPE has been mentioned. CPE is temporary access to capacity intended to replace capacity lost within the enterprise due to a planned event such as a facility upgrade or system relocation. CPE is similar to CBU in that it is intended to replace lost capacity; however, it differs in its scope and intent. Where CBU addresses disaster recovery scenarios that can take up to three months to remedy, CPE is intended for short-duration events lasting up to three days, maximum. 3. On/Off CoD. On/Off CoD is available for up to twice the ‘purchased’ capacity of a given machine. On/Off CoD upgrades are allowed for any processor configuration, up to the limit, as long as the number or capacity level of the processors is increased. Upgrades that decrease the number or the capacity level of processors is not allowed. In his response below, Tim mentions Instant Recovery. This is the same as System Recovery Boost (SRB). A few poinst about this option: 1. The name can be bit mis-leading. The 'instant' applies to the capability of ACTIVATING additional CAPACITY during/after an IPL - planned or unplanned.. 2. This is limited to a short duration i.e. minutes/hours rather than days! 3. Some the documentation states 'speed'. Remember, this refers to the 'speed' of bringing down/up of the OS and sub-systems. This is done by ACTIVATING ADDITIONAL capacity and not by changing the GHz of the processor.

First of all, what you describe was never true, not the way you describe it anyway. 1. Sub-capacity Monthly License Charge (MLC) IBM software was/is based on the monthly peak *four* hour rolling average (4HRA). A *one hour* OOCoD activation is not four hours, so it was/is mathematically impossible for your MLC to report a 4HRA equal to or even particularly near the total MSU capacity inclusive of the one hour OOCoD activation. 2. "One-Time Charge" (OTC) IBM software, a.k.a. IPLA software, allows daily OOCoD pricing -- "per MSU day." 3. You were/are also allowed to set softcapping on machines across OOCoD activation(s), and with some potential "white space" (free) capacity utilization. Sub-capacity reports will never report above the softcap(s).

With Tailored Fit Pricing peak MSUs (4HRA or otherwise) no longer matter as such. There's also now Instant Recovery on IBM z15 machines, with z/OS System Recovery Boost. There is no software reported capacity associated with legal/valid z/OS System Recovery Boost(s). >CBU won't work because the site is out of country. Does your workload qualify for Capacity for Planned Events (CPE), and are CPE's T&C compatible with cross-border requirements? -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM Z & LinuxONE -------------------------------------------------------------------------------------------------------- E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
