The SGI shared memory systems, the most current of which is called "UV", is a NUMALink interconnected design.  They have a number of ASICs that implement the interconnect and protocol and bridge to the Intel processors intra-processor link, which is called QPI.

The SGI cluster products use Infiniband for interconnect.
