Hi Patryk,

If I can answer for Martin... I think he is referring to what is 
described in the roadmap :

So, with pmxcfs, there is no more a single master node, that can be a SPOF.

And I can add, that if 'Sheepdog' was configured (distributed storage 
among the nodes), there will be no need for central storage as iSCSI, or 
FC, that are also SPOF, even if they have redundant Controller, Power 
Supply, multipath... etc (furthermore, they are very expensive). See :
