You can order a 2094-S18 with 8 CPs, certainly. However, which books run the CPs is a technical implementation detail that might be in the hands of the IBM engineers. Work with your IBM IT Specialist on that issue. It could be that all 8 CPs will run (day to day) on the first book, and that may not be a bad thing. Is there a particular reason why you want 4 on one book and 4 on the other? (Or why you want 8?) >2. where can I find the actual process model ?

With 8 CPs enabled the last digit will be an 8. So it'll be a -408, -508, -608, or -708, depending on your requirements. For the -708 model all 8 engines run at full speed. My guess is you're looking at a -508 model (if you are taking four 2064-2C5 systems and migrating the workload to two z9 ECs), but that's just a guess. Of course you can also vary the number of engines if something other than 8 makes sense. The IBM IT Specialist or business partner can help you figure out what makes the most sense. >3. Can I still use the sysplex timer 9037-002 without using the STP ? Yes, you can. The z9 EC still supports the Sysplex Timers. But you might want to look at STP anyway. Consider the cost of maintenance for the Sysplex Timers, for example, as well as floor space and electricity. STP is supposed to become generally available in January, 2007. You can also make this decision separately in the future. (For example, if you want to migrate the workload first, then worry about the Sysplex Timers, say, 6 months later, that's could be a perfectly reasonable strategy.) >4. Except the 8 CPs allocate half in each book....is there another good choice? Many are possible, but you'll have to sit down with a professional to look at your workload. >5. If I buy another new one S18 model...is it too complex to interconnect >with the 2 sets of 2064-2C5...as you know the HCD ..is quite different.. I'm a little confused since it sounds like you want to replace the z900s with the z9 EC. Are you talking about interconnection during migration? By the way, if you don't have a DR system, you might consider keeping some number of the z900s (maybe not all) and moving them to another data center. Talk to your IBM or business partner contacts about this to see if it makes sense financially and technically. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
