...and as a side comment on SAN connectivity
SAN connectivity is not required for VC...so it's up to you if you need to connect it.
On the VCB server (which we have just established should be another server), multipathing is not supported or recommended for the VMFS LUNs. That said, i usually still go with dual ports and map one to VMFS and the other to a LUN for backups to sit.
