Craig,

The GRIO looks like software to me:

sgi.com

I have e-mailed SGI for the information about their FC setup, but my guess is point-to-point, based on the fact they have used this set-up for SCSI interfaces before.

A relevant excerpt:

"XFS is a very high-performance filesystem with support for contiguous data (reduced I/Os) and both direct (non-buffered) and asychronous I/O. SGI has
demonstrated I/O through the filesystem in excess of 500 MBytes/second. Customers have demonstrated and documented high I/O and bandwidth as well. For
example, Tom Ruwart, Director of the Army High Performance Computing Lab at the University of Minnesota, has successfully tested an early "alpha" version of
XFS on a large 377 gigabyte filesystem. Using 24 SCSI channels and 24 Ciprico RAIDs, Tom measured direct I/O throughput of:
186 megabytes/second sustained read or write speed, 1 process
330 megabytes/second sustained read speed, 4 processes "
