The Path to Upgrade Data Center

With the increasing demand for high bandwidth from private cloud, public cloud data center and service providers, 25G and 100G are widely used. 200G and 400G optical devices will be successively produced and shipped from 2019. So far, most server vendors have started offering servers 25G of fiber-optic network CARDS as an I/O(input/output) option, and Ethernet’s signal transmission rate has increased from the earlier 10G to 25G, 100G or higher. While 1G, 10G and 40G currently dominate the Ethernet port market, the future demand for 25G and 100G is stronger than ever as high bandwidth is undeniably driving data centers toward greater scalability and flexibility.

Why Is 25G Coming to Data Centers?

Data centers are expanding at an unprecedented rate, driving the need for higher bandwidth connections between servers and switches. To accommodate this trend, the access network has been upgraded from 10G to 25G, providing high-density, low-cost, and low-power solutions for the connection between servers and ToR switches.

The Development History of 25G

Since its advent in 2014, Google, Microsoft, Arista Networks, Broadcom, and Mellanox have been driving the development of the 25G Ethernet standard, which is intended to enable a 25G top-shelf server network. With the increasing popularity of 25G and its rapid spread in the market, 25G will provide a comprehensive solution for the connection between server and switch in the future.

The Advantages of 25G

Before the release of 25G Ethernet standard, enterprises, operators and other data centers generally adopt the network upgrading method of 10G to 40G. With the official release of 25G Ethernet standard, 25G to 100G network upgrading method has gained more applications with the advantages of low cost, low power consumption and high density, promoting the rapid development of 100G Ethernet. Let’s take a look at the differences between 10G, 25G, 40G, and which upgrade is superior.

25G Can Provide Higher Performance Bandwidth Than 10G

In the current data center, the network connection between the server and the switch is generally between 10G and 25G. Compared with 10G, 25G is an improvement based on 10G packaging and chip technology, providing higher bandwidth and performance. The emergence of 25G enables the data center to be based on the existing network architecture without any cable interconnection, and can also support the transmission of higher rate (over 10G), meet the demand for higher bandwidth in the future network, and make the network upgrade more convenient and easy. The wiring infrastructure required for 25G and 10G transmission is basically the same, which can effectively avoid the expensive cost and the complexity of rewiring and make the network upgrade more convenient.

In addition, the 25G is similar to the 10G in that it uses a single channel of SerDes for backward compatibility, significantly reducing power consumption and costs and helping data center operators save capital and operating expenses.

Insert 25G SFP28 optical transceiver into 10G SFP+ port, what speed will we get?

Theoretically, the 25G SFP28 optical transceiver is backwards compatible with 10G SFP+ port, and its rate can reach 10G/s. However, this mode of use is not suitable for all brands of switches and optical transceivers. Considering the limitation of the fiber network card and switch port, this mode is generally not recommended.

25G Is More Suitable for High-density Requirements Than 40G

For large, high-end enterprises, the port density of the server largely determines the cost of cabling and switch infrastructure in the whole system. Therefore, compared with 40G, the cost of upgrading from 25G to 100G is relatively low. Because 25G to 100G network upgrade, the switch port is fully utilized, effectively reducing the cost of bandwidth.

It has been upgraded to a 40G network. Is it necessary to deploy a 25G network?

25G devices are expensive compared to 40G devices, so having upgraded to a 40G network, is it necessary to deploy a 25G network? Due to the cost rationalization of the 25G channel, 25G is definitely an important path to upgrade from 10G to 100G or higher in the future. If you need to increase the baud rate (signal transfer rate) or plan to upgrade the network to a higher speed (100G/200G/400G), then you must deploy the 25G network. If there is no requirement, then you do not need to deploy the 25G network.

The Prospect of 25G

At present, 25G servers and 100G switches can be seen everywhere in very large data centers. They gradually replace the earlier 10G servers and 40G switches. This network upgrade increases the throughput of the whole system by 2.5 times and reduces the incremental cost of equipment. As the Ethernet industry continues to innovate and lay the foundation for higher rate research and development, the 25G-100G upgrade model has become an important path for data centers.

25G Offers More Possibilities for 50G

As we all know, 25G can provide 2.5 times the bandwidth compared with 10G, and 50G can provide 1.25 times the bandwidth compared with 40G in the future. Currently, 50G has been proposed as the basis for 100G,200G, 400G network upgrade, but the implementation of 50G Ethernet standard still needs some time.

25G will provide more possibilities for 50G, as the implementation of 50G Ethernet can be based on two 25G channels, so it will be an alternative to the current use of four 10G channels up to 40G, reducing the cost of network equipment in the data center by reducing channel deflection. In the future, the network upgrade path may evolve from the traditional 10G-40G-100G to 10G-25G-50G-100G. In any case, upgrading a data center from multiple 25G channels to a 50G or 100G network will be simpler and more economical.

25G Lays the Foundation for 200G and 400G Network Upgrade

The 25G,50G,100G network architecture offers greater flexibility and is often used as a solution for large data centers, paving the way for later 200G/400G upgrades. At present, high-end enterprises and large data centers are shifting towards this, effectively promoting the implementation of large data centers and the interconnection between data centers. Nowadays, more and more suppliers in the market are engaged in the research and development of 200G and 400G optical devices, some of which have been successfully put into use. The implementation of 100G Ethernet is based on the development of 25G/50G. Similarly, the future network upgrade of 200G and 400G will be based on 100G. The following table lists the paths from 25G/50G/100G to 200G/400G.

Conclusion

The need for higher speed and performance in future data centers will never cease. Looking back at the evolution of 25G over the past few years, you can see that the emergence of 25G is a milestone in the next generation of data center network bandwidth and channel capacity expansion. The 25G to 100G network upgrade overturns the traditional 10G-40G network and improves the efficiency of the data center by providing higher bandwidth and port density, reducing power consumption and cost. It lays a solid foundation for the 200G/400G upgrade. Let’s wait and see how the continuous development and innovation of Ethernet will promote the new round of changes in the data center.

200G Optical Modules for the Next-generation Data Center Deployments

With 100G in wide-scale deployment today and the promise of mainstream 400G deployment seemingly ubiquitous, Cloud Data Centers are eager to take advantage of any and every opportunity to bridge the throughput gap and keep pace with the data deluge. 200G (4 x 50G) optical modules answer this immediate need head-on.

At the broader market level, while 100G technology is already mature and component integration is well established, 200G end-to-end interoperable chipsets have just recently hit the market. Looking to the past as our guide, in the short term, 200G modules are expected to emulate cost structures akin to 100G modules when they entered the market a few years ago and follow a similar downward cost curve as component integration is further standardized and volume shipments accelerate. In due course, 200G modules are expected to achieve a cost structure that’s comparable to today’s 100G modules.

While 100G CWDM is a mature and well-understood technology and will continue to ramp in the coming year, many of the big Cloud Data Center OEMs are turning their sights to 200G, to meet the pressures of enabling faster connections at scale volumes.

Google

Google started deployments in 2x200GbE transceivers in 2018 and we expect that demand for these products will peak in 2022, as Googles starts to transition to 2x400GbE modules.

Amazon

The forecast for 400GbE includes 4x100GbE DR4 modules selected by Amazon. These DR4 modules will be deployed in a breakout configuration with DR1 modules on the opposite side of the link. Effectively, each fiber will be carrying 100GbE traffic, aggregated into a DR4 module on one side. Deployments of true 400GbE transceivers will be limited in 2019-2021 to upper levels of switching in mega-datacenters and core routers. Implementation of high-radix configurations in leaf and spine networks using 400GbE connectivity will be challenging until switching ASICs reach 51Tbps capacity, probably by 2022-2023.

Facebook

Facebook is staying with 100GbE for now and plans to use 200GbE next.

More than 2.6 billion people now use its services.

Facebook publicly stated their intent to stay with 100GbE optics for now and use 200GbE or 400GbE transceivers in the next upgrade cycle in 2021-2022. Facebook’s new F16 data center network architecture， will require 3-4 times more optical connections compared to their previous design (F4). The first implementation of F16 topology will rely on 100GbE CWDM4 transceivers, boosting demand for these modules in 2020-2022.

Facebook is already the largest consumer of 100GbE CWDM4 modules. They use a sub-spec version of CWDM4 transceivers with 500-meter reach instead of 2km, also known as CWDM4-OCP (for Open Compute Project). The latest forecast database includes sub-spec CWDM4 modules as a separate category. Segmenting the sub-spec products also helped us to refine the market data collected for 2018, resulting in higher than previously reported sales.

Once these issues are resolved, the demand for CWDM4 is expected to skyrocket in the second half of 2019 and make a real difference to the market in 2020-2022. Sales of sub-spec CWDM4 modules are projected to peak in 2022, as Facebook starts the transition to 200GbE connectivity.

Conclusion

Though intermediate between 100G, and 400G – the customer demand for 200G, is shaping this market to be sizable, with deployments expected by the second half of next year. The good news for module vendors is that there are multiple component vendors, such as MACOM, who have 200G compatible components on the market today.

Comparing the cost for 100G versus 200G, we have to look specifically at the cost of components themselves. While 100G is already at the point of integration, 200G end-to-end operable chipsets have just hit the market. 200G will therefore emulate a similar price point as 100G did when it entered the market a few years ago, following a similar cost curve as integration furthers.
