Maximum size of a mapped network drive on Windows Server 2016 RRS feed

  • Question

  • I have a HP 3par system via File Persona. I need to add mapped network drives to my Windows Server 2016 from at least 50TB. I'm using SMB protocol.

    Someone told me the maximum size Win Server 2016 accept is 32TB. I'm currently looking for information but haven't found anything from HP or Microsoft.

    Could someone confirm this for me please?

  • Hi,

    Thanks for posting in our forum!

    I didn't find the official documentation about the size of the disk for network mapping.

    As far as I know, I don't think there is such a limit in Server 2016.

    Because our experimental environment is limited, we can't help you with this test. I also suggest you go to HP forum and ask HP experts if there are such restrictions.

    >>Someone told me the maximum size Win Server 2016 accept is 32TB. 

    This means that the maximum size of NTFS disk in cluster of 8K is 32TB. The value of this cluster can be changed manually. That is to say, if we change the size of the cluster, we can create disks up to 256TB.

    https://docs.microsoft.com/en-us/windows-server/storage/file-server/ntfs-overview

    In short, As long as you can create 50TB disks, there should be no problem mapping to 2016 via the network.

    Hope this can help.

    Best Regards,

    Daniel
