iscsi "windows iscsi" in a VMware 5.1 environment

Hi - confused around the use if a VMKernal Port for use of iscsi.

Now bearing in mind I am NOT using VMWare software iSCSI storage adapter.

Question is to use the iSCSI initiator inside a windows 2008 r2 server - do i really even need a VMkernal Port. If i only add a VMkernal Port I cant (inside windows) add an IP address in that iSCSI VLAN.  However If i add a Virtual Machine Port Group with a VLAN tag of the iSCSI VLAN - I can then add an adapter to the VM (place it in the iSCSI Virtual machine Port group) I can then ping the Netapp filer iscsi interface. Question is do I "still" need the  iSCSI VMkernal Port on the esx host? - Does the iscsi   still work on the Virtual machine port group (as long as its tagged with the iscsi vlan?)

If you are using using iSCSI within (inside a VM) it will use the network interface of the VM.

The VMKernel Portgroup is a special network interface portgroup for the host (ESXi OS) to send iSCSI and NFS traffic.

Question is do I "still" need the  iSCSI VMkernal Port on the esx host? -

No, because your host is NOT generating the iSCSI traffic, the VM is generating the traffic, which will flow through it's nic, virtual machine portgroup, vSwitch, physical uplink to destination.

You only need to use a VLAN if you are using them, and the label could be anything.

However, if you want to provision LUNs and NFS exports from your NetApp SAN directly to the ESXi host OS, you will need to use a VMKernel Porgroup as well....

Thanks Andrew, I had figured this out - basically the OS (Windows) noe ESX is handling the ISCSi traffic
