    The concept is to use heartbeat on a highly redundant setup. Active/Active fulfills that.

    Typically, Active-Active means that IO being read from or written to a
    particular logical device (LUN) can happen from either of two redundant
    storage controllers, or storage processors as you put it.

    I think this is misleading, the LUN is not used for HA heartbeat instead the datastore on top of it is used. D answer should read:

    “VMFS5 datastore backed by a Fibre Channel LUN on an 8GB active/active array”
