  • VSA transport options
    Posted: 11-14-2017, 1:56 AM


    I am failing to understand some of the subtleties of VSA transport mode.  Some of these questions may seem perverse but they will help sort the options in my mind.

    Starting here : https://documentation.commvault.com/commvault/v11/article?p=products/vs_vmware/c_vmw_transport_modes.htm

    * In LAN Free HotAdd mode, can the VSA and MA be on *different* machines, rather than the same VM, as per the link? I accept this may kill the benefit of "LAN Free" but I want to understand if it is possible (as an interim / transitionary config)

    * Network based Hot Add mode *does* allow different machines.  But, covering all my bases here, can VSA and MA be *combined*? 

    * Does Network based Hot Add mode *require* the VSA to be a VM on the Vmware cluster.  The link is not clear and it seems to me to be plausible that off-cluster would work in *some* cases : eg, NFS

    * I have previously been told by CommVault that putting a firewall proxy or MA on a VM is poor config and I should not expect decent performance because the VM can never match physical.   But some of these transport modes *do* have either the VSA or the MA on a VM.  That seems contradictory - unless there are caveats for transport modes that are not well documented

    * if the VSA is off-cluster, can NBD mode be considered equivalent to Network based HotAdd mode?  Or is NBD inferior, come what may?
