Is there any advantage of locating the performance data to a remote drive? We have moved the SQL database and that made me think about the
performance data. Not sure if its possible but one thing I thought of is our Backup server might be able to access the same data so it would always be up to date
with the perf data should it be brought into service. Also we would not have to move the perf data to the backup server to keep it up to date.

Thanks,

You are welcome to attempt to set up a network for the performance data. The number of writes to the rrds can cause significant io, so I would suggest that you test this in a lab before moving it to production. If you network share experiences high io latency/wait, implementing this is ill-advised. That being said, it can help reduce load, memory, and io on the XI server. If you do a large number of bandwidth checks, you may want to look at mounting /var/lib/mrtg to a remote share as well. Remember though - io wait and latency on the share will absolutely negatively impact your XI server.

Thanks for the information/suggestion.
Will do.
