Turning a Linux PC into a SAN Storage Device ?

Turning a Linux PC into a SAN Storage Device ?

I wonder if any of you guys can help me out with this; I'm pretty new
to all of this so please forgive me if I ask any daft questions...!

We currently have a FC network, to which is attached a Sony high data
rate tape drive - this all works fine, we can read/write data to this
device from attached FC clients OK.

What we need to be able to do, is also connect a Linux PC to the FC
network, and read/write data to it, the same way as the Sony drive. The
data could either be on one of the PCs disks, or on a tape drive
attached via SCSI to the PC.

Obviously the PC isn't a "normal" FC storage device, and the
application on the clients won't be able to talk to the PC in the same
way as the Sony drive.

Is there some way we can make the Linux PC appear as a FC storage
device - so that no changes are required at the client end (which are
running a more specialised, realtime OS) and we can access just like we
do to the Sony drive ?

The PC is a Dell Precision PC, running RedHat Enterprise 3 WS, and is
fitted with a QLogic QLA2200 FC HBA. It is fitted with SCSI hard drives
and CD/DVD, and also has a LTO2 tape drive attached via SCSI.

Any suggestions ?

We need to achieve a data transfer rate of at least 20MB/s.

Many thanks for your help !
