I do not disagree with what you said, but they,ve got one single CEC and one of the questions was whether they'd need two *ICFs*. While I agree that two CF partitions are a must as soon as you go multi-CEC, I don't see much benefit in having two CF partitions on a single CEC. ICF processors is another point to discuss. What is the better choice, two ICFs and no more spare or one ICF and one spare? Not sure whether a CF partition can survive an ICF failure when there is an available spare, but if it does this answers the question I think. If not, well, with two ICFs and no spare you've got a safety net for the ICF but what about the SAP? Talking about storage for the CF partition: This really only depends on what structures you place in the CF and how heavy they're used. If you only use XCF, GRS, JES2, OPERLOG, LOGREC and Catalog Sharing, you're probably far below 1GB. If you start DB2 data sharing, if can quickly grow.
