Storage space direct NIC setup RRS feed

  • Question

  • We have a Failover cluster of 3 nodes each node having 2 x 1Gbps NICs which are teamed and used for management and VM traffic on the front (the team is also a trunk carrying traffic for multiple vlans). Team is a switch dependant LACP setup and works fine. 

    The backend storage is storage space direct and the NICs were not setup by us. I am struggling to understand how they have been setup and how they are meant to work.  The setup is - 

    2 x 10Gbps NICs per node but not teamed as far as I can tell

    There are 2 storage vlans and each NIC is a trunk allowing both vlans.  

    Each vlan is associated with a different IP subnet and NIC1 has an IP from one of the subnets with NIC2 having an IP from the other subnet. 

    So basically  - 

    NIC1 - allows vlans 10 and 11 with an IP of 192.168.3.1/27  from vlan 10

    NIC2 - allows vlans 10 and 11 with an IP of 192.168.4.1/27  from vlan 11

    Does this sound right to anybody because coming from a network background if it is trunk I would expect a vswitch somewhere ie. as in the front end.  And I just don't understand how this is meant to work as we have been told both storage NICs are active on each node. 

    Any insights would be very much appreciated.
