IP configurations while doing Sql clustering on windows server 2008 R2

Hi there,I am doing a demo practicle for two node windows clustering later which I will be using for Sql clustering and HAG
for sql 2012.As I am novice in this and have little knowledge of Networking I would like to know for AD that we are using
what network address and IP address configuration should be for my DC which will be SAN also using iscsi and NOde1 and
Node2 which will be member domain for clustering.

As when I am validating my clustering it is giving me IP configuration and Network commumnication warnings.

I am doing practice on VMware using VMNET2 as switch.

Can anyone help me out here for proper configuration.....

Thanks in advance
