Hi Mike, Many experts have talked about XSTORE and VM using it for paging. All our defined XSTORE is being used for MDCACHE. It made a noticable difference to I/O performance for our VSE production guest. We could have done it all in regular storage but until a recent processor change, we didn't have much real storage that I wanted to give away. A new-to-us z800 came with a lot more memory than we used to have, so we configured some as XSTORE and MDC took it all. I wish I could claim good planning on our part.
