I'm planning to run an rsync command on Server A, to copy 40GB of files to Server B.

Server A is a production server, Server B is not.

If I run rsync on Server A, can the command detrimentally affect the performance of that server? It needs to continue to work as an FTP server during the transfer.

"Can rsync detrimentally affect the performance of the source server?"

Yes, of course, any new load can detrimentally affect the performance of a server - but you've not let us know the spec or utilisation of the source or target servers, their NICs or the bandwidth, latency and utilisation of the links between them - so we can't answer this with any degree of certainty.

For sure, rsync is gonna take all the possible bandwitch to transfer the data but you can always use the option --bwlimit like so:

rsync --bwlimit=5000 /foo user@serverB:/bar

This will limit transfering speed to 5Mb/s

Or you can also use ionice as already pointed out.
