Networking Configuration for Software iSCSI and Dependent Hardware iSCSI
If you use the software iSCSI adapter or dependent hardware iSCSI adapters, you must set up the networking for iSCSI before you can enable and configure your iSCSI adapters. Networking configuration for iSCSI involves opening a VMkernel iSCSI port for the traffic between the iSCSI adapter and the physical NIC.
Depending on the number of physical NICs you use for iSCSI traffic, the networking setup can be different.

Note
When you use a dependent hardware iSCSI adapter, performance reporting for a NIC associated with the adapter might show little or no activity, even when iSCSI traffic is heavy. This behavior occurs because the iSCSI traffic bypasses the regular networking stack.
