Evaluating and Comparing the Latest Ethernet Switches and PHY Chips

The Ethernet market is marked by technology transitions, which often result in large shifts in vendor share. Over the past several years, large data-center operators have increased the pace of technology innovation, creating markets for new speeds and new physical layers. These dynamics are behind the introduction of high-density 100G Ethernet switch chips, which also serve the new 25G and 50G Ethernet standards. The same operators also have a huge appetite for data-center interconnect (DCI) bandwidth, creating early demand for 400G Ethernet.

In Ethernet switches, Barefoot Networks, Broadcom, Cavium, Centec, Innovium, Marvell, and Mellanox are competing to win market share in data centers. These vendors are adding 100G Ethernet support along with new features for SDN and NFV. For data centers, most PHY development now focuses on 100GbE retimer chips using 25Gbps serdes technology, with 50Gbps PAM4 on the horizon.

The large size of the Ethernet switch and PHY market continues to keep it a competitive environment. "A Guide to Ethernet Switch and PHY Chips" breaks this market into three growth segments:

  • Data-center switch chips
  • 10GbE PHYs for copper (10GBase-T)
  • 100GbE gearbox PHYs and 25Gbps retimers

Unlike typical market research, this report provides technology analysis and head-to-head product comparisons. Which chips will win designs and why? How will these vendors be positioned as 100GbE ramps? Only The Linley Group’s unique technology analysis can provide this forward-looking view.

We Sort Out the Technology and the Key Vendors

“A Guide to Ethernet Switch and PHY Chips” begins with an extensive overview of this dynamic market. The report provides tutorials that help you decipher the myriad of acronyms and Ethernet standards. We explore the target markets and applications for Ethernet silicon, followed by an explanation of the common attributes of these products.

Following these introductory chapters, the report delivers a complete chapter on five leading switch vendors: Barefoot Networks, Broadcom, Cavium, Intel, and Marvell. Each vendor chapter includes company background information, full details of announced products, a discussion of the vendor’s roadmap where available, and our conclusions about the vendor and its products. Then, for each product segment, we include a chapter covering other vendors and a chapter comparing the products in the segment.

Product-segment chapters include coverage of switch chips and PHY chips. We cover switch chips from Centec, Innovium, and Mellanox. For the physical layer, we focus on 10Gbps Ethernet-over-copper chips and 100Gbps gearbox PHYs and retimers. Covered PHY vendors include Aquantia and Inphi. Finally, we offer our outlook for the leading vendors in each segment and for the overall market.
