    Default Mpio iscsi

    Hi all,

    I have the following setup
    ESX with 2 nics dedicated for iscsi
    192.168.1.2 -> connected to switch 1
    192.168.2.2 -> connected to switch 2

    ESX with 2 nics dedicated for iscsi
    192.168.1.3 -> connected to switch 1
    192.168.2.3 -> connected to switch 2

    DDS6 box with 6 nics
    eth0 + 1 form bond0 -> 192.168.0.x (management network)

    eth2 -> connected to switch 1 -> 192.168.1.1
    eth3 -> connected to switch 2 -> 192.168.2.1
    eth4 -> unused
    eth5 -> unused

    This setup is currently working.

    Now i would like to also use eth4 and 5. Will this improve speed?
    And if so, what is the best setup?

    create a bond (802.3ad) with eth2 and 4 -> connected to switch 1 -> 192.168.1.1
    create a bond (802.3ad) with eth3 and 5 -> connected to switch 2 -> 192.168.2.1

    Or

    eth2 -> connected to switch 1 -> 192.168.1.1
    eth3 -> connected to switch 2 -> 192.168.2.1
    eth4 -> connected to switch 1 -> 192.168.1.10
    eth5 -> connected to switch 2 -> 192.168.2.10

    thx in advance

    This will be the best option as LACP bonding provides no increase in bandwidth for iSCSI traffic.
