Configure host iSCSI ports and vSwitches
The ESXi host requires network ports for the iSCSI connections to the storage cluster.
It is recommended that you use IP Hash as the NIC teaming policy, which requires a single VMkernel port on a single vSwitch.
The host ports and storage cluster ports used for iSCSI must have IP addresses in the same subnet.
This task lists the high-level steps for configuring the ESXi host. If you require more detailed instructions, see the VMware publication VMware vSphere Storage for your version of ESXi.
Log in to the vSphere Client, and then select the ESXi host from the inventory pane.
On the Manage tab, click Networking.
Click Add Networking, and then select VMkernel and Create a vSphere standard switch to create the VMkernel port and vSwitch.
Configure jumbo frames for the vSwitch (MTU size of 9000, if used).
Repeat the previous step to create a second VMkernel port and vSwitch.
