Re: ASM - iSCSI and network traffic segregation
ASM/ME will need access to the SAN side to log into the VSS control volume, so since you're running that on the server that has the data it will be fine. All iSCSI related operation will occur on the SAN subnet so make sure your routing between all the interfaces on each side can reach all the other interfaces on the remote side. Not just the Group IP. So a NAT firewall can't be used between sites.
