Hey!
You can use one network for your storage management i.e. Gluster.
If you are using the cockpit-ovirt UI you can simply add the two different FQDN for the
different networks during the gluster deployment itself.
Something similar to the screenshot below. As I have only one network, I mentioned the
same network for both the inputs. But as you have two different networks you can mention
the storage network in the first field and the management network in the second.

Parth,
Thanks for taking the time to answer my question(s).
I am aware that I can use different NICs for oVirt management and
Gluster, we use it across the board in several oVirt 4.3 and 4.4
clusters.
In this case, I'm looking to add an additional layer of protection by
separating the inter-host / engine communication from external
interference.
Essentially I want to create the following configuration:
1. 10.0.1.0/24: oVirt hosted engine connection to the IT network
(oVirt web management, SSH access to engine and hosts).
2. 10.0.2.0/24: oVirt hosted engine and hosts private network. (Used
for vdsm inter host communication and VM migration).
3. 10.0.3.0/24: GlusterFS.
Now granted, I can achieve the same by adding a NAT bridge and place
the hosted engine web management on 10.0.2.0/24, but it's less than
ideal.

configuration. (And rightly so, in this case).
