Now why would I update it? Well, no matter how good your tools are, there is always room for improvement. This one is a best practise for the storage administrator and not really for the designer. There was one thing I didnt do before and it has to do with the occupancy alarm. The occupancy alarm is calculated according to the amount of disks and failover level. It shows you how much you can allocate in a pure healthy state (so that disks can fail before breaking de vRAID open). What I didnt do is giving the available free space until you hit the occupancy alarm level. So thats added here:

Nice work, you might also like this one I created a long while back (EVAQuickCalc), should still be accurate for P6000.

nice job too John. I did not use the ability to add existing LUNS with descriptions before. Maybe thats a good idea for the administrator to keep track with his environment! My approach was more from the designer/architects point of view.
For the P6x00 environments we'll have to add the Thin Provisioning and Multi-Tier functionalities.
Hans to be honest I never used the LUN's section it was more for Customers and colleagues installing EVA. I've always used it as a quick sizing tool for Customer requests, so was only really interested in the Disk group usable figures. I've not touched it in a while, but may update once I've finished tweaking a 3PAR version I'm working on.
