o Eliminated stand-alone switch costs by developing a silicon photonic wavelength-switching in each compute module and a scalable multi-dimensional switchless fabric.o Increased datacenter floor density 3x by developing “contiguous planes” of power/liquid-cooling/optical-fabric infrastructure and robotic servicing mechanisms for lights-out datacenters.o Significantly reduced system and infrastructure design costs and allowed flexible downlink/uplink port ratio by developing consolidated switch architecture.o Increased compute nodes’ network port peak bandwidth 4x while increasing high-radix switch downlink port density 4x by developing a shared switch port with WDM passive optics and TDM-based arbitration algorithms.o Reduced power consumption 2x and space requirement 10x in Exascale HPC fabric systems by consolidating photonic-copackaged switches in blade-based switch sub-chassis.o Reduced cable complexity 10x and significantly reduced deployment costs by developing multi-stage intra-chassis fiber shuffles in switch sub-chassis and employing simple inter-chassis optical trunk cables. o Reduced discrete optical transceiver density 4x by developing hot-pluggable 32-lane mid-board optical transceiver modules, a CWDM passive infrastructure and new electrical/optical connectors..o Delivered reliable and time-to-market photonic-integrated systems by creating the Houston Photonic Systems Lab and pre-developed electro-optical high-speed connectivity solutions to influence product strategy/roadmaps.o Future proof the HPE Synergy 12000 Frame by developing a photonics-ready midplane and photonic-integrated mezzanine card and switch module products.o Reduced $/port costs for servers in delivering $1B+ HPE Synergy products by developing the Rack-is-the-Enclosure architecture that optically shares high-radix “master” switch by multiple “satellite” switches in different enclosures.
