I hope Mark has repeated his search; http://google.com?q=anil+rao+fabric and http://google.com?q=seamicro+interconnect turn up lots of info. A 2011 PDF[1] at Seamicro sez, "It is a three-dimensional torus, with both path redundancy and diversity. The fabric is FLIT-based and wormhole- routed, with integrated virtual-channel technology to manage congestion, and has a throughput of 1.2 Terabits/sec." Looks like proc boards use PCIe interconnects, like the old cPCI blades. The more interesting bit (to me) is the possibility raised in an older article[2] that Rao and Lauterbach are thinking of turning their interconnect into a datacenter-level fabric. Infiniband II, anyone?
