We've got our BL460c G7 running ESXi4.1 with Lefthand P4300.
Currently we use iSCSI Software Adapter to connect to the storage and is working ok. But I just noticed
that there're 2 iSCSI adapter (Emulex OneConnect) with this blade named vmhba0 and vmhba1 both has the sam WWN.
My question is that can I use this instead of the iSCSI Software adapter ?
What is the benefit of using this ?
And how this is connected to the Lefthand P4300 ? through NIC ?

A hardware adaptor offloads the iSCSI traffic from the OS to the hardware.
It is certainly acceptable to use a hardware adaptor.
It is just another network adaptor, you configure it similarly.

Yes, you can use this instead of software iSCSI and this gives an added advantage in handling the stacks better and there should be a performance improvement also, provided the network on ESXi are configured in right manner.
Check the below guides for best practices and how to setup hardware iSCSI adapters.
