Linux, Fibre Channel and SAN?

cybermage asks: "I'm in the process of researching a dense storage system to provide storage for a web farm. I've found some cool boxes that provide 584GB in 2Us but am a bit puzzled about getting Linux to talk to them. After looking at this past article from July, I'm wondering if any new advances in with Linux and Fibre Channel SAN solutions and whether anyone out there has some practical advice/limitations on sharing a large SAN amongst several Linux servers?"
