4.2.1 XenServer Open-iSCSI initiator configuration
The XenCenter management GUI can be used to configure dedicated NICs for iSCSI storage traffic use.
Assigning a NIC for iSCSI use will prevent the use of the NIC for other functions such as host management.
However, appropriate network configuration is also required to ensure the NIC is used for the desired traffic. For
example, to dedicate a NIC to iSCSI storage traffic, the NIC, storage target, switch, and VLAN (if a VLAN is
used) must be configured so the iSCSI storage target is only accessible over the assigned NIC.
Ensure that the dedicated NICs used for iSCSI storage use a separate IP subnet that is not routable from the
XenServer management interface. Enforcing this ensures storage traffic will not be directed over the
management interface after a host reboot, which would otherwise be possible due to the initialization of the
network interfaces.
4.2.2 Assign NIC functions using the XenCenter management GUI

1. In the XenCenter management GUI, navigate to the Infrastructure view, navigate through the
objects, select the desired XenServer host, select the Networking tab, select the desired Network
