  • 1.  Storage / Networking Stack ??

    Posted Apr 18, 2012 02:33 PM

    Hello everyone,

    I have an Esxi Server, iScsi Storage Array with one LUN available.

    I configured my ESXi Storage adapter to dynamic discovery and it could successfully access the LUN in my SAN.

    My question is :

    I haven't configured any VMkernel Ports , does LUN access takes place through the Storage Stack (VMkernel) ? Or Networking Stack of ESXi ?

    What I know is " Storage means VMKernel port group " ,, I haven't configured any ,, what happen then when I configure vmkernel port binding ? do I access the lun in a different way ?

    Sorry , I'm still a beginner..

    Thanks in Advance.

    Welcome to the Community - If you are referring to the ESXi Software iSCSI Adapater it will actually use both the Storage stack and Network stack - the storage stack to maange the storage and the traffic will be carried by the network stack -

    By default a vmkernel is created when you intsall ESXi - so unless you created a new vmkernel port used specifically for iSCSI your iSCSI traffic is sharing the management port -
