Hi,
because i'm interested in economical areas of MF and not that familiar with special engine zIIP, I would like to have some information:
Usual - with classic CP - z9 or z10 software is licensed by OTC (on time charge) or MLC (monthly license charge) + maintenance.
Now I would like to make use of zIIP.
a) With sw - other than DB2 - is zIIP eligible?
b) How does this impact my charging? Need those MLC contracts to be converted to WLC (workload license charge)?
c) Are there experiences how much the benefit (proportial quantity) using zIIP maybe?
d) What is the standard ration sw parts are using zIIP?

Any hint is appreciated.

Thx

Google is your friend. Googling ziip processor returned an IBM hit that says:

What it does

The IBM System z Integrated Information Processor (zIIP) is available on all System z10 and System z9 server. It is designed to help free-up general computing capacity and lower overall total cost of computing for select data and transaction processing workloads for business intelligence (BI), ERP and CRM, and select network encryption workloads on the mainframe.

Eligible workloads include portions of the following:

* DB2 for z/OS V8 and DB2 9 for z/OS exploit the zIIP capability for portions of eligible data serving and utility workloads.
* z/OS Communications Server exploits the zIIP for eligible IPSec network encryption workloads.
* z/OS XML System Services is enabled to take additional advantage of the zIIP for eligible XML workloads.
* z/OS Global Mirror (zGM, formerly XRC Extended Remote Copy) enables DFSMS SDM (System Data Mover) processing associated with zGM/XRC to be eligible for the zIIP
* z/OS Communications Server exploits the zIIP for select HiperSockets large message traffic
* IBM Global Business Services can enable the Scalable Architecture for Financial Reporting (SAFR) enterprise business intelligence reporting solution for zIIP.
* Intra-server communications â€“ z/OS CIM Server processing eligible for zIIP (with z/OS V1.11).
* zAAP on zIIP capability - Optimize the purchase of a new zIIP or maximize your investment in existing zIIPs by enabling zAAP-eligible workloads to run on zIIPs. (additional terms and conditions apply).

The zIIP's execution environment accepts eligible work from z/OS, which manages and directs the work between the general purpose processor and the zIIP. IBM will not impose software charges on zIIP capacity
What it means

The zIIP, in effect, better enables data to be centralized on the mainframe. The ease and economy of this solution helps break down the walls between transactional datastores on the mainframe and applications that run on distributed computers. Workloads on zIIP can help connect, manage, extend, and protect the data and transactions that originate from the mainframe. With the zIIP capability, the System z9 and System z10 mainframe helps minimize the need to maintain duplicate copies of the data and provide better security between the applications and the data. Thus, zIIP can help your business by:

* Helping to improve resource optimization.
* May help lower cost of computing for eligible workloads.
* Help secure network data and help keep data stores resilient

Whether or not there will be any impact upon software charges, you need to check your contract with your vendor. There may or may not be any savings from using specialty processors -- there's too much variation in contracts to say for sure without knowing the details of that specific contract.
