I have been reviewing various documents on how to size the Page Data Sets.I was wondering if there are any guidelines on what can be used today. This should be kept to z/OS V1.12, 1.13 and 2.1 which I think will be the more dominant operating systems in use right now. I know that the number of Slots will drive what I allocate. So I am looking for the following information. I have not done this in many years so I am very rusty. 1) How to calculate the number of slots per page datasets a) I need to base this on 3390 Mod 3/9/27/54 2) What do I need to stay away from when determining where the page datasets go a) For example, if I use a Mod27 and I need to place multiple page datasets on the volume Should they all be for the same LPAR if in a PLEX Should they all be for unique LPARs if in a Plex 3) What are the maximum values I can create a page dataset? Can I use a whole Mod3/9/27/54 for ONE page dataset? I have looked through Hot Flashes (Cheryl Watson) and MXG sourclib. I have run through some of the Redbooks and share presentations. I am now looking for real life thoughts. I also thought this would be a good topic for the archives.

My old ROT was 2-3x the real memory on the LPAR. Now that we can have 16, 32, 64GB partitions, we're talking some real DASD here.
