Can I have multiple vROps instances connect to the same vCenter server and pull data from it? If so, what is the performance impact of doing this on the vCenter server?
Yes you can. It should not hurt vCenter.
Basicly vCenter is only used as a proxy to get to the ESXi host. Data is pull directly from the ESXi hosts.
Quote from here: The overhead of running vRops - Michael Ryom
vRops talks through vCenter and as such it put loads on it, but how much. As it turns out not a lot… CPU load is five to ten percent every five minutes for a duration of 30-60 seconds. What about memory then? 40-50 MB every five minutes, that is all.
Hope this answer your question
