I have two DELL R750xs servers with two SFP+ ports and two 1GB ports. I need to configure the replication of virtual machines between the two nodes. Do I necessarily have to do it via the SFP+ ports or can I also use the 1GB ports? Consider that you would like to set a response time of n. 1 minute. There will be 4 machines to replicate
 
It depends.
How much data changes each minute on those 4 guest's disks? If it's less than what the network and in turn the replication can handle, it should be fine.
 
There are 4 virtual machines, I can't quantify how much data. One of these is a s.o. windows d is the one that...
 
If it's below what you can send per minute over the 1Gbit network, it should be fine.

I'd suggest running it over the 1Gbit network and monitoring it in case the network becomes the bottleneck.
 
I understand. Listen, I initially told you that I have 2 10GB SFP+ ports available on the two servers. Can I configure the two sfp+ ports managing 2 replica virtual machines on the first port and two other virtual machines on the second port? Let me explain better, can I replicate two specific virtual machines on SFP+ port 1 and the other two on SFP+ port 2?
 
Splitting replication traffic over different links is not supported.
You can set a migration network and it will be used for replication, but all replication traffic will go over that network then.
