You have an option of 1 or 2 or 3 or 4 engines. Keep in mind one buys engines and adapts the power to them, i.e. 1-CP or U01=270MIPS, 2-CP or O02=252MIPS or 3-CP or M03=249MIPS, see the chart for the IBM 2096 offers (73 of them). Really depends on if you need engines for LPARs and dispatching or engines for MIPS in one box. I opted for engines to dispatch. My CF is dedicated and never looked to see if it could double as a CP engine. If it did, not sure about how it affect software billing. Upgrading the z800 is always a possibility depending. I upgraded an IBM 2064- 102 to an IBM 2064-103 even after the 2064 was declared obsolete through a special arrangement with IBM and N/C; although the z9BC was a done deal. I would not buy excess capacity until you need it and it can be turned on with a credit card because the available engines are all being used as spares or you can up the processing power of existing engines in very small increments. Would recommend you look at Crypto Accelerators for SSL and Crypto Cooprocessors for encryption needs. These engines are only a few thousand dollars compared to the CP engines which are are down from the $90-120K into the $50-60K range. Also would look at firms like Mainline, etc, and also IBM to make it a horse race for your dollars. IBM may not win but you can get a brand new z9BC from those third party sources with just as good as service. Just gotta love the competition these days.
