Is there a way to see or change the default location in Operations Manager for storing performance data for perf advisor? Ideally they would like to move it onto a cifs share mounted from a NetApp. Is that advisable or even possible? They want to seperate it from their OM Database to avoid filling up that drive and having OM stop monitoring when it goes below the 10% free space threshold.

CIFS share for perf data? IMHO, it is best to survey the disk space consumption and provide appropriate disk space, whether local disk or on a LUN.
Some KBs for your reading enjoyment: kb54774 to identify top disk space consumers, kb47586 for moving data in the perfArchiveDir, and kb54780 to determine if you have extra perf data files hanging around needlessly consuming disk space.

I was able to determine/change the current perf data path using "dfm options list perfArchiveDir". We ended up putting a UNC path to the cifs share which seemed to work and data is collecting to that now. There is no fibre channel/iscis on the server so a LUN is not an option. This is a short term fix until they get a server with a larger local disk hopefully.

To move the perf data to another location, you can use the below command
# dfm datastore setup -p \\cifs-server\cifs-share\perfdata
This command will take care of the entire process.
i.e. (create a new directory, if not available) and move the perf data to this directory & then finally point the DFM server to use the perf data from this new location.
Before running the command, make sure you have done the following steps to make sure DFM server get access to the CIFS share
1. Add a user having privileges on the CIFS share as an “administrator” on the DFM station.
