    Yes, but that hardlimit has to expect the number to be Very
    Large in the very near future. 16K disks on a big compute farm is not

    Yes, but what if I want to see the multiple paths? Does their
    solution allow you to specify the path behind the 'realdisk'? Does it
    allow querying of the paths?
