I will be experimenting over the next few months (with SLES10) to see what "really" works for SAP on zLinux under z/VM using VDISK.....
I know someone who runs multiple SAP systems in production with 16 GB of swap space each, primarily to satisfy the vendor requirements. Because of CP limitations they come in portions of 2 GB, so only the first one is being used to swap, if any. He monitors the usage of the VDISKs. This works. You can imagine he was pretty upset when some support person insisted he would go allocate real disk instead, because that was better (and since he was on z/VM 5.1 then, we knew it would be very much worse). I probably need to rephrase my earlier comment in that Linux swap on real disk is good for two things: to slow down Linux and to increase the bonus of your favorite storage sales person.
