Will it be normal to use the network interface through which the iscsi storage is connected also for ceph?

Question

network hardware

There is a storage connected on iscsi to servers. Each server has 2 dual-port cards for 10 gigabits - one for virtual machines, the second for iscsi connection.
The old servers didn't have room for additional disks, but the new ones had 6 free ones for sas ssd 2'5''.
Itching to try ceph, in the proxmox used, it seems to be easy and simple to configure. And according to some reviews, it works faster than a dedicated storage.
True, since all network interfaces are busy, the question arose - is it normal to use the network interface through which the iscsi storage is connected, also for ceph? Or is it better not to even try?

Answer 1

Will work. And how it will work depends on the load profile. If you have fewer than three servers, this will be more of a problem than a solution.
One more question - how are the cards configured?

Answer 2

I think this is bad practice. Firstly, cef is voracious, and in addition to iscsi traffic, you will also have cef service traffic and application traffic on the same grid. This can cause "congestion". But since you have two 10gbit network cards each, why not make a bond, on top of which make wilans and assign a guaranteed bandwidth to each wilan?
