It's DSS-G version 5.4a (no Omnipath to make 5.4b worth the effort) 
which is according to the release notes

   IBM Storage Scale RAID 6.0.1-PTF0-efix4

Which is newer than the versions mentioned when I was investigating, 
which are were all 5.x something.

I am don't really believe 400Gbps is actually low bandwidth so it's a 
"bug" somewhere IMHO.
