Right now I'm in the process of getting quotes etc for upgrading our existing FAS2020 (dual head) at our primary site and FAS2020 (single head) at our dr site to a newer filer and have received quotes from Netapp and EMC and am concerned with the performance that a newer filer will offer. Right now on the 2020 we are running into a cache buffer full issue (according to netapp support) Is there any really good data collection utility that will analyze all the performance metrics of the filer/esx hosts/virtual machines and spit out a nice little graph/numbers etc to make sure that the solution that we are looking at can first off improve our existing solution and allow for growth? Dell has a DPACK utility that gave me some good information but the more information I can get the better off I am going to be.

You have OnCommand UM installed ? Or you can ask support to provide the graphs from a perfstat collected.
Other way to look you problem statement is to provide new set of requirements viz. IOPs Read/Write/Sequential/Random and space capacity and it will be size accordingly.
