Marvell Driving Network Intelligence and Processing to the Edge

In the previous TIPS to Living on the Edge, we looked at the trend of driving network intelligence to the edge. With the capacity enabled by the latest wireless networks, like 5G, the infrastructure will enable the development of innovative applications. These applications often employ a high-frequency activity model, for example video or sensors, where the activities are often initiated by the devices themselves generating massive amounts of data moving across the network infrastructure. Cisco’s VNI Forecast Highlights predicts that global business mobile data traffic will grow six-fold from 2017 to 2022, or at an annual growth rate of 42 percent1, requiring a performance upgrade of the network.

Marvell Driving Network Intelligence and Processing to the Edge

The mobile phone has become such an essential part of our lives as we move towards more advanced stages of the “always on, always connected” model. Our phones provide instant access to data and communication mediums, and that access influences the decisions we make and ultimately, our behavior.

According to Cisco, global mobile networks will support more than 12 billion mobile devices and IoT connections by 2022.1 And these mobile devices will support a variety of functions. Already, our phones replace gadgets and enable services. Why carry around a wallet when your phone can provide Apple Pay, Google Pay or make an electronic payment? Who needs to carry car keys when your phone can unlock and start your car or open your garage door? Applications now also include live streaming services that enable VR/AR experiences and sharing in real time. While future services and applications seem unlimited to the imagination, they require next-generation data infrastructure to support and facilitate them.

Versatile New Ethernet Switch Simultaneously Addresses Multiple Industry Sectors

By Ran Gu, Marketing Director of Switching Product Line, Marvell

Due to ongoing technological progression and underlying market dynamics, Gigabit Ethernet (GbE) technology with 10 Gigabit uplink speeds is starting to proliferate into the networking infrastructure across a multitude of different applications where elevated levels of connectivity are needed: SMB switch hardware, industrial switching hardware, SOHO routers, enterprise gateways and uCPEs, to name a few. The new Marvell® Link Street™ 88E6393X, which has a broad array of functionality, scalability and cost-effectiveness, provides a compelling switch IC solution with the scope to serve multiple industry sectors.

The 88E6393X switch IC incorporates both 1000BASE-T PHY and 10 Gbps fiber port capabilities, while requiring only 60% of the power budget necessitated by competing solutions. Despite its compact package, this new switch IC offers 8 triple speed (10/100/1000) Ethernet ports, plus 3 XFI/SFI ports, and has a built-in 200 MHz microprocessor. Its SFI support means that the switch can connect to a fiber module without the need to include an external PHY – thereby saving space and bill-of-materials (BoM) costs, as well as simplifying the design. It complies with the IEEE 802.1BR port extension standard and can also play a pivotal role in lowering the management overhead and keeping operational expenditures (OPEX) in check. In addition, it includes L3 routing support for IP forwarding purposes.

Marvell Link Street 88E6393X

Adherence to the latest time sensitive networking (TSN) protocols (such as 802.1AS, 802.1Qat, 802.1Qav and 802.1Qbv) enables delivery of the low latency operation mandated by industrial networks. The 256 entry ternary content-addressable memory (TCAM) allows for real-time, deep packet inspection (DPI) and policing of the data content being transported over the network (with access control and policy control lists being referenced). The denial of service (DoS) prevention mechanism is able to detect illegal packets and mitigate the security threat of DoS attacks.

The 88E6393X device, working in conjunction with a high performance ARMADA® network processing system-on-chip (SoC), can offload some of the packet processing activities so that the CPU’s bandwidth can be better focused on higher level activities. Data integrity is upheld, thanks to the quality of service (QoS) support across 8 traffic classes. In addition, the switch IC presents a scalable solution. The 10 Gbps interfaces provide non-blocking uplink to make it possible to cascade several units together, thus creating higher port count switches (16, 24, etc.).

This new product release features a combination of small footprint, lower power consumption, extensive security and inherent flexibility to bring a highly effective switch IC solution for the SMB, enterprise, industrial and uCPE space.

Understanding Today’s Network Telemetry Requirements

By Tal Mizrahi, Feature Definition Architect, Marvell

There have, in recent years, been fundamental changes to the way in which networks are implemented, as data demands have necessitated a wider breadth of functionality and elevated degrees of operational performance. Accompanying all this is a greater need for accurate measurement of such performance benchmarks in real time, plus in-depth analysis in order to identify and subsequently resolve any underlying issues before they escalate.

The rapidly accelerating speeds and rising levels of complexity that are being exhibited by today’s data networks mean that monitoring activities of this kind are becoming increasingly difficult to execute. Consequently more sophisticated and inherently flexible telemetry mechanisms are now being mandated, particularly for data center and enterprise networks.

A broad spectrum of different options are available when looking to extract telemetry material, whether that be passive monitoring, active measurement, or a hybrid approach. An increasingly common practice is the piggy-backing of telemetry information onto the data packets that are passing through the network. This tactic is being utilized within both in-situ OAM (IOAM) and in-band network telemetry (INT), as well as in an alternate marking performance measurement (AM-PM) context.

At Marvell, our approach is to provide a diverse and versatile toolset through which a wide variety of telemetry approaches can be implemented, rather than being confined to a specific measurement protocol. To learn more about this subject, including longstanding passive and active measurement protocols, and the latest hybrid-based telemetry methodologies, please view the video below and download our white paper.

Storing the World’s Data

By Marvell, PR Team

Storage is the foundation for a data-centric world, but how tomorrow’s data will be stored is the subject of much debate. What is clear is that data growth will continue to rise significantly. According to a report compiled by IDC titled ‘Data Age 2025’, the amount of data created will grow at an almost exponential rate. This amount is predicted to surpass 163 Zettabytes by the middle of the next decade (which is almost 8 times what it is today, and nearly 100 times what it was back in 2010). Increasing use of cloud-based services, the widespread roll-out of Internet of Things (IoT) nodes, virtual/augmented reality applications, autonomous vehicles, machine learning and the whole ‘Big Data’ phenomena will all play a part in the new data-driven era that lies ahead.

Further down the line, the building of smart cities will lead to an additional ramp up in data levels, with highly sophisticated infrastructure being deployed in order to alleviate traffic congestion, make utilities more efficient, and improve the environment, to name a few. A very large proportion of the data of the future will need to be accessed in real-time. This will have implications on the technology utilized and also where the stored data is situated within the network. Additionally, there are serious security considerations that need to be factored in, too.

So that data centers and commercial enterprises can keep overhead under control and make operations as efficient as possible, they will look to follow a tiered storage approach, using the most appropriate storage media so as to lower the related costs. Decisions on the media utilized will be based on how frequently the stored data needs to be accessed and the acceptable degree of latency. This will require the use of numerous different technologies to make it fully economically viable – with cost and performance being important factors.

There are now a wide variety of different storage media options out there. In some cases these are long established while in others they are still in the process of emerging. Hard disk drives (HDDs) in certain applications are being replaced by solid state drives (SSDs), and with the migration from SATA to NVMe in the SSD space, NVMe is enabling the full performance capabilities of SSD technology. HDD capacities are continuing to increase substantially and their overall cost effectiveness also adds to their appeal. The immense data storage requirements that are being warranted by the cloud mean that HDD is witnessing considerable traction in this space.

There are other forms of memory on the horizon that will help to address the challenges that increasing storage demands will set. These range from higher capacity 3D stacked flash to completely new technologies, such as phase-change with its rapid write times and extensive operational lifespan. The advent of NVMe over fabrics (NVMf) based interfaces offers the prospect of high bandwidth, ultra-low latency SSD data storage that is at the same time extremely scalable.

Marvell was quick to recognize the ever growing importance of data storage and has continued to make this sector a major focus moving forwards, and has established itself as the industry’s leading supplier of both HDD controllers and merchant SSD controllers.

Within a period of only 18 months after its release, Marvell managed to ship over 50 million of its 88SS1074 SATA SSD controllers with NANDEdge™ error-correction technology. Thanks to its award-winning 88NV11xx series of small form factor DRAM-less SSD controllers (based on a 28nm CMOS semiconductor process), the company is able to offer the market high performance NVMe memory controller solutions that are optimized for incorporation into compact, streamlined handheld computing equipment, such as tablet PCs and ultra-books. These controllers are capable of supporting reads speeds of 1600MB/s, while only drawing minimal power from the available battery reserves. Marvell offers solutions like its 88SS1092 NVMe SSD controller designed for new compute models that enable the data center to share storage data to further maximize cost and performance efficiencies.

The unprecedented growth in data means that more storage will be required. Emerging applications and innovative technologies will drive new ways of increasing storage capacity, improving latency and ensuring security. Marvell is in a position to offer the industry a wide range of technologies to support data storage requirements, addressing both SSD or HDD implementation and covering all accompanying interface types from SAS and SATA through to PCIe and NMVe.
