Martha, we found it is better to go with some xstor but not a lot we found it is better to page to xstor than dasd we tried it with a lot of XSTOR and a little XSTOR so 30 central and 5 expanded sounds good
munson 201-418-7588 From: Martha McConaghy <[email protected]> To: [email protected] Date: 12/16/2010 01:56 PM Subject: Expanded storage question Sent by: The IBM z/VM Operating System <[email protected]> I know that this question has come up numerous times in the past, but I'm don't recall ever seeing a consensus on it. I know that z/VM needs expanded storage. However, deciding how much is the trick. We will be moving to a z10 early in the new year. I'm trying to decide how to divide the storage. If an LPAR is going to be running a lot of Linux guests (some of them quite large), is it better to put as much storage into main as possible with a small expanded....or cut back on the amount of main and put it towards expanded? I've done the former in the past. However, we now have a lot more Linux servers than ever before, some of which are running pretty heavy apps, like Oracle. The current LPAR does do a lot of paging to expanded and disk. While there will be more storage on the z10, it isn't a lot amount more. So, for example, if I have 35G to use for 1 LPAR, would it be better to define 30G main and 5G expanded or 25G main and 10G expanded?
