Before SAN connectivity via the vSphere 4 iSCSI software adapter can be enabled, a specific network configuration is required. To correctly enable connectivity, a VMkernel network must be created with sufficient network access to the iSCSI SAN. As a best practice, use at least two Gigabit network adapters teamed together for performance and failover. As a best practice, the VMkernel network for iSCSI should be separate from the management and virtual networks used by virtual machines.
