We use a mix. ECK DASD for the system and also for high attention data (some systems with db2 bundled) Because it's easy and safe to handles, we use VM Secure. And really stable.
Some customer data is on NFS mounted NAS. And we are just starting to use FCP, via defined EDEV. Will use it for customer data. Since we use SSI, and also at need really moving guests between our two systems, you have to take this into consideration when choosing disk type. It depends, as usually :-) Tore Agblad Infrastructure Architect - Mainframe zOpen HCL Technologies Ltd.

They are: 1) Everything on 3390 storage 2) Everything on non-3390, external disk via a fiber card 3) A combination of 1 & 2 What are the thoughts on using these? Is one preferred over the other?
