10 Gbps connection from my backup server to vcenter

Hi Experts,

my backup server 2012R2 has 2 NIC interfaces, one 1Gbps and one 10Gbps.
My Vcenter has the same.

I want to make my vcenter backups over the 10Gbps interface but this is not working.
From my backup server I can ping the vcenter device.

What is still wrong ?

More than likely a routing issue with traffic going through the 1 Gbps card. The easiest way to solve this would be to give the 10 Gbps cards IP addresses in a differrent subnet to the 1 Gbps cards.

Drop and disable the 1GB nic.

The ip address of the 10G nic is absolutly different network.

1G = 10.2.1.90
10G = 192.168.40.11

This is really weird.
From backup server I can ping the vcenter over 192.168.40.11.
But I cannot connect to vcenter.
Do I have to enable the 10G interface on vcenter site ?

My NETAPP is on the same subnet 192.168.40.0
Here I can connect from backup server to NETAPP.

if you can ping vCenter Server, you should be able to connect?

did you check, if the firewall was enabled?

did you check 902, 80 and 443 TCP ports ?

yes now I am connected.
So I can reach the vcenter through the new NIC.

But when I check the backup server, the data is not coming over the 10G NIC it is still over the 1G NIC.
On my backup server I have set to 10G NIC and IP4 and no other NIC is allowed.

How this can be ?

disconnect the 1GB backup nic?

when I disconnect 1GB nic, then the whole vcenter goes down and all connections.

On my backup server I have set a host entry -> vcenter 192.168.40.11
This works and I can connect to my vcenter over the 10G nic.

But when backup starts I cannot see any traffic on the 10G nic inside the vcenter.

Why its so weird ?

what is the backup server?

is it supposed to backup vCenter Server ?

I use Backup Exec with vmware agents.
The backup goes to deduplication storage array. This array is direct attached with 6Gbps adapter.

no the server goes directly to vcenter, not to esxi.
The vcenter has the second nic with other subnet.
