Vsphere 5.5 and WFCS No Shared Disk

Hi to all...

I would like to create a SQL Always On Across Physical Hosts (ESXi and vCenter 5.5U2) (CAB, right?)

I read these 2 kb and I would like a clarification:

VMware KB: Microsoft Clustering on VMware vSphere: Guidelines for supported configurations   (1037959)

VMware KB: MSCS support enhancements in vSphere 5.5   (2052238)

In the Notes (KB 1037959), under the table, it says:

Microsoft Clustering Services (MSCS) virtual machines use a shared Small Computer System Interface (SCSI) bus. Any virtual machine using a shared bus cannot make hot changes to virtual machine hardware as this will disrupt the heartbeat between the MSCS nodes. These activities are not supported and will cause MSCS node failover: 

  • vMotion migration 
  • Increasing the size of disks 
  • Hot adding memory 
  • Hot adding CPU 
  • Using snapshots 
  • Pausing and/or resuming the virtual machine state 
  • Memory over-commitment leading to virtual swapping or memory ballooning

These notes, are applies to WFCS with Shared Disk, or even WFCS without shared disk?

In Table reads:

Thanks to all for any clarifications?
