According to the following book, there are 3 lines in the z900 series. The 101-109 have a book that contains 12 PUs, of which up to 9 can be normal processors (CP's). Even though IBM doesn't spell it out this way, the 1C1 thru 1C9 and the 110-116 actually form a single line or processors, having a book that contains 20 PU's of which up to 16 can be CP's. These machines have the same clock speed as the 101-109 line. The turbo line, which is the 2C1-2C9 and 210-216 models also have the 20 PU book, again with up to 16 MP's in the box. The clock speed on this line is faster than the other 2 lines (hence the turbo definition). According to the book, any of the three lines can be upgraded within the line by using CUoD or CIU (whatever that is).
Based on the above, my guess is that the "capacity" models simply mean they have the 20 PU book rather than the 12 PU book, thus allowing more capacity within the same box without any kind of hardware upgrade. http://www-03.ibm.com/servers/eserver/zseries/library/refguides/pdf/g326 3092.pdf Rex -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Eric Bielefeld Sent: Friday, March 24, 2006 10:40 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: z900 "Capacity Models"? I thought that the capacity model allowed you to go all the way from 1 processor to the maximum number of processors. I think the z/900 comes with books containing 8 processors each. You order 1 book if you need between 1 and 8 CPs, 2 if you need between 9 and 16, with a maximum of 3 books (I think). The capacity model allows you to go from 1 CP to the maximum, without having to install anything. You are allowed to upgrade if you started with say 3 CPs, you can go all the way up to 8 without having to install anything.
