As it enables each succeeding IB speed, the company examines new markets for its leading switch and adapter architectures. For ConnectX-5, it targeted high-performance-computing (HPC) co-design. The company says its new HDR products could find a home in machine-learning applications, including embedded IoT support. By enabling the 50Gbps HDR signaling rate, Mellanox provides more port capability than the mainstream four-lane HDR. The Quantum switch implements a two-lane 100Gbps version of HDR, dubbed HDR100, as an alternative to four-lane EDR designs. The InfiniBand Trade Association roadmap specifies a 12-lane 600Gbps version of HDR too, although 12-lane implementations are few because faster 4-lane designs typically supplant them. Mellanox is ensuring that ConnectX-6 avoids being pigeonholed as an IB adapter. As with previous generations, the product handles IB and Ethernet protocols. For the switch fabric, the company offers InfiniBand-only switches and Ethernet-only switches, the latter in the Spectrum family. The search for artificial-intelligence (AI) applications has brought both IB and its largest supporter, Mellanox, to a crossroads. The design of products meeting HDR specifications has occurred well in advance of equivalent 200GbE or 400GbE switches and adapters. Yet Intel’s transition to its Omni-Path Architecture (OPA) has hindered the HPC market for IB. Mellanox focuses on establishing the performance and resource benefits of IB relative to the OPA, but as it brings IB to new markets, tackling the competition may require more than a simple one-to-one feature comparison. (Onload versus Off-Load architecture is more than a 'one-to-one feature comparison'; (Sorry, Ms. Wirbel !)
