All,
I put together a quick program which calculates the actual usable space you get based on the various configuration options you can set on a filer. It's a .net application but I'm guessing it should run via wine for any *nix folks. I need to add SAS disks as an option, and if anyone knows of an authoritative source on rightsizing (I calculated the percentages based on looking at specific disk information).
Anyway, it's somewhat thrown together and not completely finished, but I thought I would see if any folks out there might find it useful before I wasted any more time on it. Also, it would be nice to see how close it gets to people's actual configurations. I'm guessing there might be some rounding errors as well as some fuzzy rightsizing.
love to get some feedback, Nick
