We are installing an ESS in the next couple of weeks and I'm interested
in any recommendations anyone has on appropriate volume sizes for the
database and storage pools on this device.

Currently, we are OS/390 V2.10 with everything on an RVA2 with 3390-3
device sizes.  With the ESS, you can go up to 'mod-27' sizes.  Any
guidelines out there for mod-3 vs. mod-9 vs. bigger would be
appreciated.

Thanks,
