Rightsizing Ethernet

By George Hervey, Principal Architect, Marvell

Implementation of cloud infrastructure is occurring at a phenomenal rate, outpacing Moore’s Law. Annual growth is believed to be 30x and as much 100x in some cases. In order to keep up, cloud data centers are having to scale out massively, with hundreds, or even thousands of servers becoming a common sight.

At this scale, networking becomes a serious challenge. More and more switches are required, thereby increasing capital costs, as well as management complexity. To tackle the rising expense issues, network disaggregation has become an increasingly popular approach. By separating the switch hardware from the software that runs on it, vendor lock-in is reduced or even eliminated. OEM hardware could be used with software developed in-house, or from third party vendors, so that cost savings can be realized.

Though network disaggregation has tackled the immediate problem of hefty capital expenditures, it must be recognized that operating expenditures are still high. The number of managed switches basically stays the same. To reduce operating costs, the issue of network complexity has to also be tackled.

Network Disaggregation
Almost every application we use today, whether at home or in the work environment, connects to the cloud in some way. Our email providers, mobile apps, company websites, virtualized desktops and servers, all run on servers in the cloud.

For these cloud service providers, this incredible growth has been both a blessing and a challenge. As demand increases, Moore’s law has struggled to keep up. Scaling data centers today involves scaling out – buying more compute and storage capacity, and subsequently investing in the networking to connect it all. The cost and complexity of managing everything can quickly add up.

Until recently, networking hardware and software had often been tied together. Buying a switch, router or firewall from one vendor would require you to run their software on it as well. Larger cloud service providers saw an opportunity. These players often had no shortage of skilled software engineers. At the massive scales they ran at, they found that buying commodity networking hardware and then running their own software on it would save them a great deal in terms of Capex.

This disaggregation of the software from the hardware may have been financially attractive, however it did nothing to address the complexity of the network infrastructure. There was still a great deal of room to optimize further.

802.1BR
Today’s cloud data centers rely on a layered architecture, often in a fat-tree or leaf-spine structural arrangement. Rows of racks, each with top-of-rack (ToR) switches, are then connected to upstream switches on the network spine. The ToR switches are, in fact, performing simple aggregation of network traffic. Using relatively complex, energy consuming switches for this task results in a significant capital expense, as well as management costs and no shortage of headaches.

Through the port extension approach, outlined within the IEEE 802.1BR standard, the aim has been to streamline this architecture. By replacing ToR switches with port extenders, port connectivity is extended directly from the rack to the upstream. Management is consolidated to the fewer number of switches which are located at the upper layer network spine, eliminating the dozens or possibly hundreds of switches at the rack level.

The reduction in switch management complexity of the port extender approach has been widely recognized, and various network switches on the market now comply with the 802.1BR standard. However, not all the benefits of this standard have actually been realized.

The Next Step in Network Disaggregation
Though many of the port extenders on the market today fulfill 802.1BR functionality, they do so using legacy components. Instead of being optimized for 802.1BR itself, they rely on traditional switches. This, as a consequence impacts upon the potential cost and power benefits that the new architecture offers.

Designed from the ground up for 802.1BR, Marvell’s Passive Intelligent Port Extender (PIPE) offering is specifically optimized for this architecture. PIPE is interoperable with 802.1BR compliant upstream bridge switches from all the industry’s leading OEMs. It enables fan-less, cost efficient port extenders to be deployed, which thereby provide upfront savings as well as ongoing operational savings for cloud data centers. Power consumption is lowered and switch management complexity is reduced by an order of magnitude

The first wave in network disaggregation was separating switch software from the hardware that it ran on. 802.1BR’s port extender architecture is bringing about the second wave, where ports are decoupled from the switches which manage them. The modular approach to networking discussed here will result in lower costs, reduced energy consumption and greatly simplified network management.

Making Better Use of Legacy Infrastructure

By Ron Cates, Senior Director, Product Marketing, Networking Business Unit

The flexibility offered by wireless networking is revolutionizing the enterprise space. High-speed Wi-Fi®, provided by standards such as IEEE 802.11ac and 802.11ax, makes it possible to deliver next-generation services and applications to users in the office, no matter where they are working.

However, the higher wireless speeds involved are putting pressure on the cabling infrastructure that supports the Wi-Fi access points around an office environment. The 1 Gbit/s Ethernet was more than adequate for older wireless standards and applications. Now, with greater reliance on the new generation of Wi-Fi access points and their higher uplink rate speeds, the older infrastructure is starting to show strain. At the same time, in the server room itself, demand for high-speed storage and faster virtualized servers is placing pressure on the performance levels offered by the core Ethernet cabling that connects these systems together and to the wider enterprise infrastructure.

One option is to upgrade to a 10 Gbit/s Ethernet infrastructure. But this is a migration that can be prohibitively expensive. The Cat 5e cabling that exists in many office and industrial environments is not designed to cope with such elevated speeds. To make use of 10 Gbit/s equipment, that old cabling needs to come out and be replaced by a new copper infrastructure based on Cat 6a standards. Cat 6a cabling can support 10 Gbit/s Ethernet at the full range of 100 meters, and you would be lucky to run 10 Gbit/s at half that distance over a Cat 5e cable.

In contrast to data-center environments that are designed to cope easily with both server and networking infrastructure upgrades, enterprise cabling lying in ducts, in ceilings and below floors is hard to reach and swap out. This is especially true if you want to keep the business running while the switchover takes place.

Help is at hand with the emergence of the IEEE 802.3bz™ and NBASE-T® set of standards and the transceiver technology that goes with them. 802.3bz and NBASE-T make it possible to transmit at speeds of 2.5 Gbit/s or 5 Gbit/s across conventional Cat 5e or Cat 6 at distances up to the full 100 meters. The transceiver technology leverages advances in digital signal processing (DSP) to make these higher speeds possible without demanding a change in the cabling infrastructure.

The NBASE-T technology, a companion to the IEEE 802.3bz standard, incorporates novel features such as downshift, which responds dynamically to interference from other sources in the cable bundle. The result is lower speed. But the downshift technology has the advantage that it does not cut off communication unexpectedly, providing time to diagnose the problem interferer in the bundle and perhaps reroute it to sit alongside less sensitive cables that may carry lower-speed signals. This is where the new generation of high-density transceivers come in.

There are now transceivers coming onto the market that support data rates all the way from legacy 10 Mbit/s Ethernet up to the full 5 Gbit/s of 802.3bz/NBASE-T – and will auto-negotiate the most appropriate data rate with the downstream device. This makes it easy for enterprise users to upgrade the routers and switches that support their core network without demanding upgrades to all the client devices. Further features, such as Virtual Cable Tester® functionality, makes it easier to diagnose faults in the cabling infrastructure without resorting to the use of specialized network instrumentation.

Transceivers and PHYs designed for switches can now support eight 802.3bz/NBASE-T ports in one chip, thanks to the integration made possible by leading-edge processes. These transceivers are designed not only to be more cost-effective, they also consume far less power and PCB real estate than PHYs that were designed for 10 Gbit/s networks. This means they present a much more optimized solution with numerous benefits from a financial, thermal and a logistical perspective.

The result is a networking standard that meshes well with the needs of modern enterprise networks – and lets that network and the equipment evolve at its own pace.

Further Empowerment of the Wireless Office

By Yaron Zimmerman, Senior Staff Product Line Manager, Marvell

In order to benefit from the greater convenience offered for employees and more straightforward implementation, office environments are steadily migrating towards wholesale wireless connectivity. Thanks to this, office staff will no longer be limited by where there are cables/ports available, resulting in a much higher degree of mobility. It will mean that they can remain constantly connected and their work activities won’t be hindered – whether they are at their desk, in a meeting or even in the cafeteria. This will make enterprises much better aligned with our modern working culture – where hot desking and bring your own device (BYOD) are becoming increasingly commonplace.

The main dynamic which is going to be responsible for accelerating this trend will be the emergence of 802.11ac Wave 2 Wi-Fi technology. With the prospect of exploiting Gigabit data rates (thereby enabling the streaming of video content, faster download speeds, higher quality video conferencing, etc.), it is clearly going to have considerable appeal. In addition, this protocol offers extended range and greater bandwidth through multi-user MIMO operation – so that a larger number of users can be supported simultaneously. This will be advantageous to the enterprise, as less access points per users will be required.

Pipe

An example of the office floorplan for an enterprise/campus is described in Figure 1 (showing a large number of cubicles and also some meeting rooms too). Though scenarios vary, generally speaking an enterprise/campus is likely to occupy a total floor space of between 20,000 and 45,000 square feet. With one 802.11ac access point able to cover an area of 3000 to 4000 square feet, a wireless office would need a total of about 8 to 12 access points to be fully effective. This density should be more than acceptable for average voice and data needs. Supporting these access points will be a high capacity wireline backbone.

Increasingly, rather than employing traditional 10 Gigabit Ethernet infrastructure, the enterprise/campus backbone is going to be based on 25 Gigabit Ethernet technology. It is expected that this will see widespread uptake in newly constructed office buildings over the next 2-3 years as the related optics continue to become more affordable. Clearly enterprises want to tap into the enhanced performance offered by 802.11ac, but they have to do this while also adhering to stringent budgetary constraints too. As the data capacity at the backbone gets raised upwards, so will the complexity of the hierarchical structure that needs to be placed underneath it, consisting of extensive intermediary switching technology. Well that’s what conventional thinking would tell us.

Before embarking on a 25 Gigabit Ethernet/802.11ac implementation, enterprises have to be fully aware of what all this entails. As well as the initial investment associated with the hardware heavy arrangement just outlined, there is also the ongoing operational costs to consider. By aggregating the access points into a port extender that is then connecting directly to the 25 Gigabit Ethernet backbone instead towards a central control bridge switch, it is possible to significantly simplify the hierarchical structure – effectively eliminating a layer of unneeded complexity from the system.

Through its Passive Intelligent Port Extender (PIPE) technology Marvell is doing just that. This product offering is unique to the market, as other port extenders currently available were not originally designed for that purpose and therefore exhibit compromises in their performance, price and power. PIPE is, in contrast, an optimized solution that is able to fully leverage the IEEE 802.1BR bridge port extension standard – dispensing with the need for expensive intermediary switches between the control bridge and the access point level and reducing the roll-out costs as a result. It delivers markedly higher throughput, as the aggregating of multiple 802.11ac access points to 10 Gigabit Ethernet switches has been avoided. With fewer network elements to manage, there is some reduction in terms of the ongoing running costs too.

PIPE means that enterprises can future proof their office data communication infrastructure – starting with 10 Gigabit Ethernet, then upgrading to a 25 Gigabit Ethernet when it is needed. The number of ports that it incorporates are a good match for the number of access points that an enterprise/campus will need to address the wireless connectivity demands of their work force. It enables dual homing functionality, so that elevated service reliability and resiliency are both assured through system redundancy. In addition, supporting Power-over-Ethernet (PoE), allows access points to connect to both a power supply and the data network through a single cable – further facilitating the deployment process.

The Challenges Of 11ac Wave 2 and 11ax in Wi-Fi Deployments How to Cost-Effectively Upgrade to 2.5GBASE-T and 5GBASE-T

By Nick Ilyadis, VP of Portfolio Technology, Marvell

The Insatiable Need for Bandwidth: Standards Trying to Keep Up

With the push for more and more Wi-Fi bandwidth, the WLAN industry, its standards committees and the Ethernet switch manufacturers are having a hard time keeping up with the need for more speed. As the industry prepares for upgrading to 802.11ac Wave 2 and the promise of 11ax, the ability of Ethernet over existing copper wiring to meet the increased transfer speeds is being challenged. And what really can’t keep up are the budgets that would be needed to physically rewire the millions of miles of cabling in the world today.

The Latest on the Latest Wireless Networking Standards: IEEE 802.11ac Wave 2 and 802.11ax

The latest 802.11ac IEEE standard is now in Wave 2. According to Webopedia’s definition: the 802.11ac -2013 update, or 802.11ac Wave 2, is an addendum to the original 802.11ac wireless specification that utilizes Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) technology and other advancements to help increase theoretical maximum wireless speeds from 3.47 gigabits-per-second (Gbps), in the original spec, to 6.93 Gbps in 802.11ac Wave 2. The original 802.11ac spec itself served as a performance boost over the 802.11n specification that preceded it, increasing wireless speeds by up to 3x. As with the initial specification, 802.11ac Wave 2 also provides backward compatibility with previous 802.11 specs, including 802.11n.

IEEE has also noted that in the past two decades, the IEEE 802.11 wireless local area networks (WLANs) have also experienced tremendous growth with the proliferation of IEEE 802.11 devices, as a major Internet access for mobile computing. Therefore, the IEEE 802.11ax specification is under development as well.  Giving equal time to Wikipedia, its definition of 802.11ax is: a type of WLAN designed to improve overall spectral efficiency in dense deployment scenarios, with a predicted top speed of around 10 Gbps. It works in 2.4GHz or 5GHz and in addition to MIMO and MU-MIMO, it introduces Orthogonal Frequency-Division Multiple Access (OFDMA) technique to improve spectral efficiency and also higher order 1024 Quadrature Amplitude Modulation (QAM) modulation support for better throughputs. Though the nominal data rate is just 37 percent higher compared to 802.11ac, the new amendment will allow a 4X increase of user throughput. This new specification is due to be publicly released in 2019.

Faster “Cats” Cat 5, 5e, 6, 6e and on

And yes, even cabling is moving up to keep up. You’ve got Cat 5, 5e, 6, 6e and 7 (search: Differences between CAT5, CAT5e, CAT6 and CAT6e Cables for specifics), but suffice it to say, each iteration is capable of moving more data faster, starting with the ubiquitous Cat 5 at 100Mbps at 100MHz over 100 meters of cabling to Cat 6e reaching 10,000 Mbps at 500MHz over 100 meters. Cat 7 can operate at 600MHz over 100 meters, with more “Cats” on the way. All of this of course, is to keep up with streaming, communications, mega data or anything else being thrown at the network.

How to Keep Up Cost-Effectively with 2.5BASE-T and 5BASE-T

What this all boils down to is this: no matter how fast the network standards or cables get, the migration to new technologies will always be balanced with the cost of attaining those speeds and technologies in the physical realm. In other words, balancing the physical labor costs associated to upgrade all those millions of miles of cabling in buildings throughout the world, as well as the switches or other access points. The labor costs alone, are a reason why companies often seek out to stay in the wiring closet as long as possible, where the physical layer (PHY) devices, such access and switches, remain easier and more cost effective to switch out, than replacing existing cabling.

This is where Marvell steps in with a whole solution. Marvell’s products, including the Avastar wireless products, Alaska PHYs and Prestera switches, provide an optimized solution that will help support up to 2.5 and 5.0 Gbps speeds, using existing cabling. For example, the Marvell Avastar 88W8997 wireless processor was the industry’s first 28nm, 11ac (wave-2), 2×2 MU-MIMO combo with full support for Bluetooth 4.2, and future BT5.0. To address switching, Marvell created the Marvell® Prestera® DX family of packet processors, which enables secure, high-density and intelligent 10GbE/2.5GbE/1GbE switching solutions at the access/edge and aggregation layers of Campus, Industrial, Small Medium Business (SMB) and Service Provider networks. And finally, the Marvell Alaska family of Ethernet transceivers are PHY devices which feature the industry’s lowest power, highest performance and smallest form factor.

These transceivers help optimize form factors, as well as multiple port and cable options, with efficient power consumption and simple plug-and-play functionality to offer the most advanced and complete PHY products to the broadband market to support 2.5G and 5G data rate over Cat5e and Cat6 cables.

You mean, I don’t have to leave the wiring closet?

The longer changes can be made at the wiring closet vs. the electricians and cabling needed to rewire, the better companies can balance faster throughput at lower cost. The Marvell Avastar, Prestera and Alaska product families are ways to help address the upgrade to 2.5G- and 5GBASE-T over existing copper wire to keep up with that insatiable demand for throughput, without taking you out of the wiring closet. See you inside!

Marvell and Mythware Introduce “Classroom Cloud” in Primary and Secondary Schools

By Yong Luo, Marvell China CSI Technical Support Director

Recently, Marvell and local China customer Nanjing Mythware Information Technology Co., Ltd. (Mythware), cooperated to create a brand new wireless network interactive teaching tool –the Mythware Classroom Cloud. Compact and exquisitely designed, this wireless network teaching solution is the first brand new educational hardware product based on Mythware’s more than 10 years of experience in education informatization and multimedia audio and video technologies.

mythware

The introduction of the Mythware Classroom Cloud, as well as its supplementary interactive classroom software, effectively solves some common wireless network equipment-related teaching application challenges, such as instability, frequent dropping offline and data transmission errors. Thus, the innovative Interactive teaching can be successfully carried out wirelessly. This not only enhances the efficiency of teaching, but also brings new vigor and vitality into primary and secondary classrooms.

mythware2

The Mythware Classroom Cloud incorporates a complete set of Marvell high-performance Wi-Fi enterprise-class wireless solutions, offering 2.4G and 5G operating frequency bands, and wireless throughput of up to 1900Mbit/s. The solution includes a dual-core 1.6GHz CPU – the ARMADA® 385. It also uses Marvell’s Avastar® 88W8864 – an 802.11ac 4X4 Wi-Fi chip. And, last but not least, the unit boasts a four-port Gigabit Ethernet transceiver, Marvell’s Alaska® 88E1543. Marvell’s solutions have been widely used in the Cisco enterprise cloud and Linksys high-end routers.

The Marvell ARMADA 385 CPU chip, with super data processing and computing capability, is built into the Mythware Classroom Cloud. It provides strong protection for sending and receiving large-capacity cloud files in the classroom. The CPU also provides abundant interfaces, so you can connect hard drives directly through the SATA 3.0 interface, which helps the Mythware Classroom Cloud to support up to 8TB of storage.

This is especially important for schools with poor network conditions. Teachers can upload resources such as courseware to the Classroom Cloud’s hard drives before school time, and call on the resources directly in class. That enables students to enjoy multimedia teaching resources immediately and without interruption, effectively solving problems caused by inaccessible networks or limited network bandwidth. The Mythware Classroom Cloud enables full real-time interconnection between teacher’s and student’s end devices, sending and receiving documents, arranging homework and accessing teaching resources in real time, without needing them to be forwarded by campus servers.

mythware3

One of the biggest highlights of the Mythware Classroom Cloud is that its lightweight body contains “wireless” super energy. Marvell’s Avastar 88W8864 802.11ac 4X4 wireless chip significantly improves the bandwidth utilization, as well as further upgrading data transmission capacity and reliability. It also provides trusted network support for a variety of multimedia file transmission in the wireless network teaching environment, ensuring the stability of classroom interactions.

One of its outstanding features is that teachers can use the wireless network in the classroom to send high-definition video (8Mbit/s) to more than 60+ mobile terminal devices with different operating systems, completely in sync and without delay. At the same time, teachers no longer have to worry about screen-pausing problems when broadcasting a PPT screen or demonstrating 3D graphic models.

And, when teachers use some interactive features (such as group teaching, sharing the whiteboard, initiating discussion and quick answer, survey and evaluations) during the teaching process, the problems of intermittent playback and the network dropping offline are solved.

mythware4

In addition, the Alaska 88E15433 Ethernet transceiver chip mounted in the Marvell solution provides stable and reliable Gigabit Ethernet connections, and Marvell’s 88PG877 power management chip provides voltage stability for the Mythware Classroom Cloud. It also supports flexible power supply modes: local AC and 802.3af PoE powering. With its special rotary chuck design, the Mythware Classroom Cloud equipment can be easily installed on classroom walls or ceilings.

mythware5

Mythware was founded in 2007, and for the past 10 years its main business has been educational software. Its core product – classroom interactive system software – enjoys a market share of up to 95% in China. It also supports up to 24 different languages, and is exported to over 60 countries and regions. Domestic and global users now exceed 31 million. By 2017, Mythware plans to fully transform into an integrated hardware and software supplier, focusing on intelligent hardware, big data, cloud platform, and will continue to release a large number of new hardware products and solutions. New opportunities for cooperation between Marvell and Mythware will continue to emerge.

Ethernet Darwinism: The survival of the fittest (or the fastest)

By Michael Zimmerman, Vice President and General Manager, CSIBU

The most notable metric of Ethernet technology is the raw speed of communications. Ethernet has taken off in a meaningful way with 10BASE-T, which was used ubiquitously across many segments. With the introduction of 100BASE-T, the massive 10BASE-T installed base was replaced, showing a clear Darwinism effect of the fittest (fastest) displacing the prior and older generation. However, when 1000BASE-T (GbE – Gigabit Ethernet) was introduced, contrary to industry experts’ predictions, it did not fully displace 100BASE-T, and the two speeds have co-existed for a long time (more than 10 years). In fact, 100BASE-T is still being deployed in many applications. The introduction — and slow ramp — of 10GBASE-T has not impacted the growth of GbE, and it is only recently that GbE ports began consistently growing year over year. This trend signaled a new evolution paradigm of Ethernet: the new doesn’t replace the old, and the co-existence of multi variants is the general rule. 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 years1.

Ethernet-Diversity

Hence, a new market reality evolved: there is less of a cannibalizing effect (i.e. newer speed cannibalizing the old), and more co-existence of multiple variants. This new diversity will require a set of solutions which allow effective support for multiple speed interconnect. Two critical capabilities will be needed:

  1. Ability to economically scale-down to a few ports2
  2. Support of multiple Ethernet speeds

Marvell launched a new set of Ethernet interconnect solutions that meet this evolution pattern. The first products in the family are the Prestera® 98DX83xx 320G interconnect switch, and the Alaska® 88X5113 25G/40G Gearbox PHY. The 98DX83xx switch fans-out up to 32-ports of 10GbE or 8-ports of 40GbE, in economical 24x20mm package, with power of less than 0.5Watt/10G port.

Interconnect1

The 88X5113 Gearbox converts a single port of 40GbE to 25GbE. The combination of the two devices creates unique connectivity configurations for a myriad of Ethernet speeds, and most importantly enables scale down to a few ports. While data center- scale 25GbE switches have been widely available for 64-ports, 128-ports (and beyond), a new underserved market segment evolved for a lower port count of 25GbE and 40GbE. Marvell has addressed this space with the new interconnect solution, allowing customers to configure any number of ports to different speeds, while keeping the power envelope to sub-20Watt, and a fraction of the  hardware/thermal footprint of comparable data center solutions. The optimal solution to serve low port count connectivity of 10GbE, 25GbE, and 40GbE is now well addressed by Marvell. Samples and development boards with SDK are ready, with the option of a complete package of application software.

Interconnect2

  1. In the mega data center market, there is cannibalization effect of former Ethernet speeds, and mass migration to higher speeds. However, in the broader market which includes private data centers, enterprise, carriers, multiple Ethernet speeds co-exist in many use cases.
  2. Ethernet switches with high port density of 10GbE and 25GbE are generally available. However, these solutions do not scale down well to sub-24 ports, where there is pent-up demand for devices as proposed here by Marvell.

By Yaniv Kopelman, Networking and Connectivity CTO, Marvell

As organizations continue to invest in data centers to host a variety of applications, more demands are placed on the network infrastructure. The deployment of white boxes is an approach organizations can take to meet their networking needs. White box switches are a “blank” standard hardware that relies on a network operating system, commonly Linux-based. White box switches coupled with Open Network Operating Systems enable organizations to customize the networking features that support their objectives and streamline operations to fit their business.

Marvell is committed to powering the key technologies in the data center and the enterprise network, which is why we are proud to be a contributor to the OpenSwitch Project by The Linux Foundation. Built to run on Linux and open hardware, OpenSwitch is a full-featured network operating system (NOS) aimed at enabling the transition to disaggregated networks. OpenSwitch allows for freedom of innovation while maintaining stability and limiting vulnerability, and has a reliable architecture focused on modularity and availability. The open source OpenSwitch NOS allows developers to build networks that prioritize business-critical workloads and functions, and removes the burdens of interoperability issues and complex licensing structures that are inherent in proprietary systems.

As a provider of switches and PHYs for data center and campus networking markets, Marvell believes that the open source OpenSwitch NOS will help the deployment of white boxes in the data center and campus networks. Developers will be able to build networks that prioritize business-critical workloads and functions, removing the burdens of interoperability issues and complex licensing structures that are inherent in proprietary systems.

Our first contribution is to port the Marvell Switch Software Development Kit (CPSS) to support OpenSwitch. This contribution to an industry standard NOS will enable Marvell devices to be widely used across different markets and boxes.
