proxmox management interface matters?

[ieronymous]

Hi

I d like to ask about a use case scenario that I am into. Proxmox will be installed on a server with extra 10g card apart from a quad intel i350 (4x1g ports). What I want to accomplish is have a quick net path between Proxmox and a Nas server in order for Vm backups to be transferred quickly.

Do I have to setup proxmox management interface on that 10g card in order to achieve that?

If I use one of the four 1g ports for management how to dictate prox to use the 10g road when backups VMs to the other server?

Thank you

Hi,

No, actually Proxmox VE's API daemon listens on all interfaces by default, for basically all traffic heavy connections that PVE uses you can configure what network they should use, e.g., live-migration traffic, and also storage entries are configured separately.

When adding a NFS/CIFS/... storage you configure the server hostname or IP address, so it's just important that you set that such that it goes over the 10G NIC to your NAS.

If I use one of the four 1g ports for management how to dictate prox to use the 10g road when backups VMs to the other server?

Well, how would the Proxmox VE connected to the NAS and the rest of the LAN, if those are different networks (two switches, one switch with VLANs or a direct connection between PVE and the NAS) it would be straight forward, else if all is one single network (IP address wise) you could configure a specific route for the address of the NAT to go over the 10g NIC.

Probably that cleared things a little bit more. If during creating an NFS share (for a remote storage between 2 servers under linux isnt NFS the best way to setup a share?) I use the remote's server ip which corresponds to the 10g card of his, that is the one part. How then prox decides that ti will use the 10g road instead of 1g. All that knows is that it has 2 connection card upon it (1g and 10g) ...... so the next step for the answer here is how these 2 servers are connected? The answer is directly from one network card to the other (no switch involved in between).

Still, checked backup schedule both at Datacenter level and at VM level. You can only choose the storage for the backup (ok since it is remote storage that underline dictated the remote server's path) and nowhere the network path to be followed

Well, how would the Proxmox VE connected to the NAS and the rest of the LAN,

Proxmox to one main switch via 1g port for net access and management.
NAS to the same main switch via 1g port for net access and management.
Proxmox -> Nas via 10g DAC cable between their 10g cards.

So if prox and nas using a network segment of 192.168.10.0/24 for net access and management, I could go to the port that corresponds to the 10g card in proxmox gui and create a vmbr10 bridge with a different net segment for instance 172.10.10.0/24. But yet, how to tell prox to use that network instead of the default. No options during VM backup (Datacenter or local) to specify the network road I wan to be followed.

Create Datacenter -> Storage item with that 10G subnet and select backup option.
