  I've used many sbus DAS FDDI boards...every one I've seen has been a
dual-width board.

  Several manufacturers are using the smaller FDDI connectors to fit two on the
plate of a PCI board (anyone know what those connectors are called?) but I
haven't seen anyone using those connectors to fit two on a single sbus board.

  I'd suggest using a SAS FDDI board (they're all over the place) and get a
small concentrator (with DAS A & B connectors) to put on the ring...then use an
M connector (SAS) to go to the SAS FDDI board.  It's another box, and it's more
expensive, but it'll save you that slot.
