How and what are Fibrechannel drives used for?

[imzjustplayin]

I don't understand the point or the use for fibre channel drives when they have SCSI drives.. I thought the only purpose for fibre channel was to link up a SAN/DAS/NAS (nas unlikely) to networked machines. This is where my knowledge about SANs/DAS' gets fuzzy. You have the drives, HBA and storage processor but I don't really understand how they all link up. Drives connect to HBA then storage processor then to network? Where does the fibre channel all fit in? Is it fibre channel drive, HBA, storage processor then fibre channel network?

What benefit would fibre channel provide over SCSI drives anyways?

fc is like an ethernet network but of hard drives. for example, you can have a fc switch and hook up lots of drives onto the switch, then ano computer with a fc card can connect to the network and use any drive

look up iscsi, it's allows block level access to a device over an ethernet network. a lot like a fc network.
