In 2003 we saw the emergence of the 10GbE server adapter market with only several 
Intel is the dominant 10GbE adapter market player. They are viewed by many as the commodity option who checks the majority of the feature boxes while delivering reasonable performance. Both Mellanox and QLogic are the exascale players as their silicon carries Infiniband specific features which they’ve convinced this market are important. In storage Chelsio rules as they’ve focused considerable silicon towards offloading the computational requirements of iSCSI. For the low latency and performance over BSD compliant TCP and UDP sockets sought by the financial traders of the world, Solarflare is king. This leaves one remaining actor, Broadcom, and in fact, they were acquired by Avago who also picked up Emulex. The word is they’ve dramatically cut their Ethernet controller development staff right after having completed their 25GbE controller ASIC, which may be why we’ve not seen it reach the market.
So as the 10GbE market sees feature & performance gains as the silicon is migrated over the next several years to 25GbE and 50GbE expect to continue seeing these four players dominate in their respective niches: Intel, Mellanox, Qlogic, Solarflare & Chelsio. I view this final phase as the fifth wave.
