We do

However in every particular case architecture is different. See there's always a block back end for any file protocol so in case of StarWind we go "classic" so failover NFSv41 and SMB3 file shares and layered on top of an HA iSCSI block layer being put on SAS (or SATA) itself. Some other companies (NetApp) do native NFS, layer it on top of SAS and expose block (iSCSI) as file put on WAFL partition. Some companies (EMC) do block and file independent (SMB3 and iSCSI and NFS).
P.S. You can get both Data ONTAP and whatever EMC is using inside their VNX arrays as Virtual Storage Appliances (firmware runs inside as a virtual machine) to play with.
