These factors are making the data and communication network providers invest in multiple parallel computing and storage resources as a way of scaling to meet demands. The ultimate goal is to pack as many Ethernet ports at the highest commercially available speed onto the Ethernet switch, and make it the most economical and power efficient. Within a data center a classic approach to networking is a hierarchical one, with an individual rack using a leaf switch — also termed a top-of-rack or ToR switch — to connect within the rack, a spine switch for a series of racks, and a core switch for the whole center. However, in the broader market which includes private data centers, enterprise, carriers, multiple Ethernet speeds co-exist in many use cases. Looking for our Products? This trend signaled a new evolution paradigm of Ethernet: Port extenders can be oversubscribed or non-oversubscribed, which means the ratio of upstream bandwidth to downstream bandwidth can be programmable from 1:

With less technical complexity within the port extenders, there were perceived benefits that would come from lower per unit cost compared mxrvell a full bridge switch, in addition to power savings. Many in the data center industry saw this as the marbell step in disaggregating the network hardware and the management software controlling it. Within a data center a classic approach to networking is a hierarchical one, with an individual rack using a leaf switch — also termed a top-of-rack or ToR switch — to connect within the rack, a spine switch for a series of racks, and a core switch for the whole center.
With Ethernet deployment and 100hase happening fastest in the data center, Ethernet switch architecture built for the data center dominates and forces adoption by the enterprise and carrier markets. Whether at home, at work, or on the move with our smartphones and other mobile computing devices, cloud compute and storage resources are omnipresent.
Fortunately, the technology to bridge lower speed ports to higher density switches has existed for several years. The high density switch 1000base the control bridge, while the devices which fan out the lower speed ports are the port extenders.
The innovation in eghernet centers drives higher density and higher port speeds but many segments of the market still need a solution with lower port speeds with different densities. Two critical capabilities will be needed: Marvell offers a collaborative fast-paced environment where innovative ideas can really make a difference. Seen as mavrell second stage of network disaggregation, this approach effectively leads to decoupling the port connectivity from the processing power in the parent switch, creating a far more modular approach to networking.
In essence, one high end, high port density switch can fan out hundreds or even thousands of lower speed ports. This simplified operational deployment results in the number of managed entities limited to only the high end control bridges. Samples and marvll boards with SDK are ready, with the option of a complete package of application software. This new paradigm shift has made architecture decisions in the data center critical and influential across all Ethernet markets.
However, the data center deployment model is different. The introduction of 40GbE and 25GbE augmented the wide diversity of Ethernet speeds, and although 25GbE was rumored to displace 40GbE, it is expected that 40GbE ports will still be deployed over the next 10 years 1.
However, these solutions do not scale down well to sub ports, where there is pent-up demand for devices as proposed here by Marvell.
Bridging the Gap Efhernet, the technology to bridge lower speed ports to higher density switches has existed for several years.

Most of the leading cloud service providers, with their significant buying power and technical skills, recognised that they could save substantial cost by designing and building their own network equipment. This trend signaled a new evolution paradigm of Ethernet: Along with the silicon solution, software reference code is available and can be easily integrated to a control bridge.
Two critical capabilities will be needed:. Looking for our Products? Additional options such as Marvell DSA, or programmable headers are possible. The most notable metric of Ethernet technology is the raw speed of communications.
This new diversity will require a set of solutions which marve,l effective support for multiple speed marvlel. Marvell has launched multiple purpose-built port extender products, which allow fan-out of 1GbE and 10GbE ports of 40GbE and GbE higher speed ports. Driver Downloads Download the latest Marvell drivers for your specific device or application. January 9th, Ethernet Darwinism: In the mega data center market, there is cannibalization effect of former Ethernet speeds, and mass migration to higher speeds.

Ability to economically scale-down to a few ports 2 Support of multiple Ethernet speeds Marvell launched a new set of Ethernet interconnect solutions that meet this evolution pattern.
The IEEE standards codified the The Prestera PIPE family will facilitate the deployment of top-of-rack switches at half the cost and power consumption of a traditional Ethernet switch. Etehrnet, a new market reality evolved: January 20th, The New Scaling Paradigm:
