EXECUTIVE SUMMARYPDF

Cloud-based services and the data centers required to deliver those services are driving strong demand for high-performance switch chips that can handle up to 12.8 Tbit/s in a single device. Following significant investment over the past five years, there are now more companies than ever before with competitive Ethernet switch chips. The market is rapidly moving to 100 Gbit/s connections within large data centers, but there is still a strong market for Ethernet switch chips with large numbers of 10 Gbit/s and 25 Gbit/s ports. The industry is now preparing for the move to 200 Gbit/s and 400 Gbit/s with the first switch devices in production and the first systems introduced.

Software developers have introduced enhanced network operating systems and stacks with support for software-defined networking (SDN) that will run on a wide range of hardware platforms. This development has given network operators an alternative to the software provide by switch system manufacturers. Several switch chip vendors and switch manufacturers have developed switch chips and systems that can be easily programmed through open software interfaces or using open packet processing languages, such as Programming Protocol-Independent Packet Processors (P4).

There is a strong and growing market for high-performance switch chips largely driven by the growth of public and private cloud data centers. The industry is already installing switches with 100GE ports and expecting to move to 200 GE and 400 GE toward the end of 2019 and through 2020. The latest switch chip families include devices that support 6.4 Tbit/s and 12.8 Tbit/s and provide significantly greater flexibility and features than previous generations.

The market for third-party switch operating systems and software to support for SDN continues to grow. Most network operators can now choose between software solutions provided by the switch manufacturer and these third-party solutions. Several companies have developed switch chips and systems that can be easily programmed through open software interfaces or using open packet processing languages, such as P4. Although this flexibility seems to be very well received, there is growing evidence that performance and price are significantly more important.

Multi-Terabit Switch Chips & Software details and analyzes more than 40 high-performance Ethernet switch devices, embedded SDN, operating system software and IP solutions, identifying the key requirements and highlighting the advantages they hold for equipment manufacturers and service providers. It also reviews vendor strategies and surveys component features, performance and flexibility in this important market. Further, this report profiles 15 vendors in the market.

COMPANIES COVERED

Demand for switch chips continues to grow, driven by cloud services and the huge increase in bandwidth used by high-definition video and other applications. The shift to cloud services and network virtualization has completely changed the switch market, which is now dominated by the needs of hyperscale and large data centers. In addition, much of the network functionality is shifting onto servers using NFV with physical and virtual switches forwarding packets between servers and to users.

Data Center Switching Enters the 400G Era

Heavy Lifting Analyst Notes
Simon Stanley
10/31/2018
 

The first 400G data center switches have been announced as the Broadcom 12.8Tbit/s and 8Tbit/s Tomahawk 3 switch chips start mass production.

Tomahawk 3 switch chips are used in the Arista 7060X4 Series and in new systems from Celestica, Delta Networks, Edgecore Networks and Quanta. Innovium is planning production shipments of TERALYNX switch chips before the end of 2018, Mellanox expects to be shipping the 6.4Tbit/s Spectrum-2 switch chips during the first quarter of 2019, and several other companies are developing switch chips with 400Gbit/s ports for introduction during 2019. Taken together with the introduction of 400Gbit/s QSFP-DD and OSFP optical modules, these developments will lift data center switching from 100 Gbit/s to 400 Gbit/s during 2019 and 2020.

We have seen unprecedented investment in high-performance switch chips in response to growing demand from data center operators for 400G switching and 6.4 Tbit/s, 12.8 Tbit/s or larger switch systems. More than $500 million has already been committed to three startups -- Barefoot Networks, Innovium and Nephos -- and Broadcom has introduced a new generation of all its three switch chip product lines, namely Tomahawk, Trident and StrataDNX.

Barefoot, Innovium and Nephos are believed to have important design wins, and Barefoot Tofino switch chips are shipping in the Arista 7170 series switches. Smaller switch chips with 25Gbit/s interfaces and 100Gbit/s uplinks are shipping from Centec Networks and Marvell.

Heavy Reading's new report, Multicore Processors Accelerating Network Virtualization: A Competitive Analysis, identifies and analyzes vendors developing high-performance switch chips, embedded software-defined networking (SDN) and operating systems software, as well as switch IP. The report profiles the vendors and analyses the switch chip architectures and devices, identifying their key features and highlighting the advantages they hold for service providers and system developers. The report includes not only information on switch chips, but also offers insights into how the overall switch market is developing.

The first generation of 400GE switch chips use 16nm technology and 50G PAM4 serial interfaces. Broadcom and Innovium and are the only companies so far to announce 12.8Tbit/s switches. There are now six companies shipping 100GE switch chips, including Barefoot, Broadcom, Innovium, Marvell, Mellanox and Nephos, and most have both 6.4Tbit/s and 3.2Tbit/s solutions. Some of these switch chips support important new features, including in-band telemetry. Several switch architectures support user programming, including through the use of P4; however, for most applications, performance, capacity and cost seem to be more important.

Recent investment in switch chips is also benefiting the market for 25GE and 10GE switch systems. Barefoot, Broadcom and Nephos are all shipping 16nm devices with 48 or more 10/25GE ports and up to 13 100GE uplinks. Broadcom, Centec Networks, Marvell and Nephos are shipping 28/32nm devices with 48 10GE ports and up to eight 100GE uplinks.

Most switch system suppliers provide a standard operating system configuration; however, network operators can now also choose from a growing list of third-party operating system suppliers. These include Arrcus, Cumulus Networks, IP Infusion and Pica8. All these operating systems work with most Broadcom switch chips, but some also work with switch chips from other suppliers. Many network operators are now implementing a mix of physical and virtual switching using SDN. There are also several companies providing software solutions for accelerating virtual switching and routing, managing large networks of virtual and physical switches, and implementing FPGA-based switch systems. These include 6Wind, Big Switch Networks, Corsa Technology and Packet Architects.

In conclusion, this is the most competitive switch market for many years. Data center and network operators have many more options of switch chip, switch system and switch software to choose between. Both the branded and white-box switch markets are seeing significant growth. Many switch system suppliers are working with multiple switch chip and software vendors to give their customers maximum flexibility. The leading switch chip vendors are already working on next-generation switch families based on 7nm technology that will increase the maximum switch chip capacity to 25.6 Tbit/s. The architectures of these next-generation designs will likely be heavily based on the current generation.
