I am in the process of testing moving our user catalogs to SMS so that we can use RLS in ZOs V2.2
It all works just fine and looks like a very good performance benefit.. Historically we have a volume for each user catalog. I guess this goes back to the days of reserves, etc. All catalog type reserves are now converted, and I/O to the catalogs is typically very low using ECS sharing, and I would expect even lower with RLS buffering. So my question is, is it safe to place multiple user catalogs on a volume? I am using guaranteed space in SMS, so will be directing specific catalogs to specific volumes, so can keep 'hot' catalogs separate if needed, but I don't think the single volume per catalog is justified, especially as the trend is for volumes with more and more space. Appreciate any comments.
