Sorry, I completely lost focus on this thread...
Latest SV-RAID download's ReadMe lists a very small list of supported browsers:
Only browsers that support JAVA Applets are supported (Windows - IE 10/11, Chrome till v44; RedHat and SUSE Firefox till v51, Chrome till v44)
...and even these might require some additional configuration steps regarding access restrictions.
Perhaps a later version of SV-RAID will get rid of its Java base..
...and it would be great if someone in Fujitsu might drop a note somewhere somewhen, preferrably here, of course.
