The manufacturers didn't want to have a public discussion before because
they wanted to be first on the market (in most cases, and this still
happens today).

Most big companies use some kind of FC SAN.  If you buy stuff off eBay
FC is also affordable for home since FC disks seem to be inexpensive.
The only thing you'd need would be a FC backplane (or use T-cards) to
connect the drives.

The new SATA and serial SCSI look interesting since SATA uses the SCSI
command set (and IIRC can be connected to serial SCSI controllers, but
I could have that backwards).  The only drawback with SATA is the one
drive/controller limit.
