You probably all know the relatively simple RAID boxes exporting a bunch of SATA disks as one big drive via FC, SAS or iSCSI, like the HP StorageWorks MSA2000, Infortrends EonStore series or many different other models from different manufacturers.
Is it possible to create such a device with Linux, a few disks and an FC controller, using the controller in the reverse direction than usual?
This would come handy to test some ideas and concepts in an emerging SAN environment.
