Update for all. The deployment finally detect the SAS collected storage. After 
manual compile the driver for the RAID control PCI card.Nir is correct. FC 
detect anything that is not "NFS, iSCSI". As this time it also detect a local 
connected SATA SSD.

Correct. FC in oVirt means actually not "iSCSI". Any device - including local
devices - that multipath expose, and is not iSCSI is considered as FC.

This is not officially supported and not documented anywhere. I learned
about it only we tried to deploy strict multipath blacklist allowing
only "iscsi"
or "fc" transport, and found that it broke users' setups with sas other esoteric
storage.

Since 4.4 is the last feature release, this will never change even if it is not
documented.
