I think you'd need 3 FC-AL adapters to get 300MB/sec.  

What sort of a machine are you going to put this in?  You shouldn't
saturate a single 64/66 PCI bus, but there won't be a lot of space left
over for, say, networking, or anything else.  Two PCI busses would be
Better.  I think you'll want some pretty decent processors, and a
boatload of ram if you're going to do this with software striping.  What
platform are you thinking of using?  SPARC, SGI?  Not x86, we trust.
