A recent example is the announcement of our HiWire Switch cable and open-source implementation with Microsoft that helps realize Microsoft’s vision for a network-managed dual-ToR architecture, overcoming complex and slow legacy enterprise approaches, simplifying deployment, and improving connection reliability in the datacenter. The multi-billion dollar data infrastructure market that we serve is driven largely by hyperscalers, HPC and 5G infrastructure.
We partner with Microsoft on our HiWire Switch AEC and open-source implementation that helps realize Microsoft’s vision for a highly reliable network-managed dual-Top-of-Rack (ToR) architecture (a network architecture design in which computing equipment located within the same or an adjacent rack are, for redundancy, connected to two in-rack network switches, which are, in turn, connected to aggregation switches via fiber optic cables), overcoming complex and slow legacy enterprise approaches, simplifying deployment and improving connection reliability in the data center.
