I am new to Storage engineering so may not be asking questions the correct way. So bear with me. This is in context of deploying Vsphere 5.0 with Netapp FAS 6000 series storage. The esxi 5.0 hosts will run almost all kinds of vms ( windows , linux , database servers etc) . I have been reading some stuff NFS vs. iSCSI in a VMWare environment | The SAN Technologist, there is also one by netapp and vmware research .
The earlier post had some criticism on NFS based datastores, but the research paper shows that almost all protocols offer same kind of performance. So then how to decide on one over the other ?
Also can iSCSI or NFS based datastores be always given to the hypervisor first and then they are made available to guests or can guests have direct access to the same. Would appreciate some reference to read on this stuff.
