Configure network interface on nodes

[sand-max]

Hi guys!
I need advice for best practice of configure network in my case (cluster 6 nodes and storage iSCSI)
I have 10_Gi SFP card and 2 interface there:
- enp7s0f0
- enp7s0f1

For example I tried 2 ways for configure ones:
1:
enp7s0f0.vlan_iSCSI-1if
vmbr0 (enp7s0f0) -VMs
vmbr0 - IP_addr-management- corosync_ring0

enp7s0f1.vlan_iSCSI-2if
vmbr1 - IP_addr-management- corosync_ring1

2: Use IP on vmbr
enp7s0f0.vlan_iSCSI-1if
enp7s0f0.vlan_corosync_ring0
vmbr0 (enp7s0f0) -VMs
vmbr0.Vlan_corosync_ring0 - IP_addr-management- corosync_ring0
vmbr0.Vlan_iSCSI-1if - IP_addr- iSCSI-1if

enp7s0f1.vlan_iSCSI-2if
enp7s0f1.vlan_corosync_ring2
vmbr1.Vlan_corosync_ring1 - IP_addr-management- corosync_ring1
vmbr1.Vlan_iSCSI-2if - IP_addr- iSCSI-2if

P.S. I am afraid Is good idea set IP addr for storage on vmbr?

Hi,

it is generally no good Idea to use two NICs for all networks.
VLAN is not a dedicated network.
And this does not protect you from latency problems.
If you have HA enabled you need a dedicated corosync network.
