[Users] which file system for shared disk?

[Piotr Szubiakowski]

Hi,
gluster is good in scenario when we have many hosts with own storage and 
we aggregate these pieces it into one shared storage. In this situation 
data is transferred via Ethernet ore Infiniband. In our scenario we have 
centralized storage accedes via Fibre Channel. In this situation it 
would be more efficient when data would be transferred through FC.

Thanks,
Piotr
