It's not clear yet which z9 the original poster has. Moving from a z9 BC to a z114, no. There are more capacity models in the z114 and more configurable engines available but with the same capacity starting points, so there's more choice, not less. Moreover, a z114 could be an appropriate upgrade from a smaller z9 EC. It's very possible a z114 could provide *more* engines with the same overall PCI. Moving from a z9 EC to a z196, maybe, but there's still more overall flexibility. The z9 EC only permits up to the first eight engines as sub-capacity engines, while the z196 supports up to 15 sub-capacity engines. There's also a double MSU "technology dividend" in that move. (Yes, there's a technology dividend from z10 EC to z196, too -- a bit in MSU terms plus AWLC.) And presumably the original poster would be moving to AWLC on the z196, meaning sub-capacity licensing would be available, if he doesn't already have that. "Money" is overwhelmingly correlated with peak utilization, not capacity -- and with a very curvaceous curve past the base investment. If the original poster has a 6xx or 7xx z9 EC, then it's possible that they could move to a z196 with more engines in a 4xx or perhaps 5xx configuration. For example, if they've got a z9 EC 703 (1607 PCI, 229 MSUs), they could move to a z114 Y03 (1788 PCI), W04 (1595), X04 (1941), V05 (1723). They could also move to a z196 408 (1667) or 503 (1642). Every one of those options except the X04 would have fewer MSUs than the z9 EC 703. And every one of those options would have AWLC or AEWLC in addition to the MSU change. Note that both the z114 and z196 support HiperDispatch. The best thing to do is to sit down with a system architect or specialist to determine the right fit for the workloads. But, to net it out, reducing the number of engines is an unlikely *requirement*, even for money reasons. -------------------------------------------------------------------------------------------------------- Timothy Sipples Resident Enterprise Architect (Based in Singapore) E-Mail: timothy.sipp...@us.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
