Navigating Product Name Changes for Marvell Ethernet Adapters at HPE

By Todd Owens, Technical Marketing Manager, Marvell

Hewlett Packard Enterprise (HPE) recently updated its product naming protocol for the Ethernet adapters in its HPE ProLiant and HPE Apollo servers. Its new approach is to include the ASIC model vendor’s name in the HPE adapter’s product name. This commonsense approach eliminates the need for model number decoder rings on the part of Channel Partners and the HPE Field team and provides everyone with more visibility and clarity. This change also aligns more with the approach HPE has been taking with their “Open” adapters on HPE ProLiant Gen10 Plus servers. All of this is good news for everyone in the server sales ecosystem, including the end user. The products’ core SKU numbers remain the same, too, which is also good.

For HPE Ethernet adapters for HPE ProLiant Gen10 Plus and HPE Apollo Gen10 Plus servers, the name changes were fairly basic. Under this new naming protocol, HPE moved the name of the adapter’s manufacturer to the front and added “for HPE” to the end. For example, what was previously named “HPE Ethernet 10/25Gb 2-port SFP28 QL41232HLCU Adapter” is now “Marvell QL41232HLCU Ethernet 10/25Gb 2-port SFP28 Adapter for HPE”. The model number, QL41232HLCU, did not change.

The table below shows the new naming for the HPE adapters using Marvell FastLinQ I/O technology and makes it very easy to match up ASIC technology, connection type and form factor across the different products.

Inevitably, there are a few challenges with the new approach, especially for the adapters used in Gen10 servers. The first is that the firmware in the adapters is not changing. So, when a customer boots up the server, the old model information, such as 524SFP+, will be displayed on the system management screens. The same applies to information passed from the adapter to other management software, such as HPE Network Orchestrator. However, in HPE’s configuration tools – One Config Advanced (OCA) – only the new names and model numbers appear, with no mention of the original numbers. This could create confusion when you’re configuring a system and it boots up, displaying a different model number than the one you are actually using.

Additionally, it is going to take some time for operating system vendors like VMware and Microsoft to update their hardware compatibility listings. Today, you can go to the VMware Compatibility Guide (VCG) and search on a 621SFP28 with no problem. But search on a QL41401 or QL41401-A2G, and you will come up empty. HPE is also working on updating its QuickSpec documents with the new naming, and that will take some time as well.

So, while the model number decoder rings are no longer required, you will need to have easy to access cross references to match the new name to the old model. To support you on this, we have updated all our key collateral for HPE-specific Marvell® FastLinQ® Ethernet adapters on the Marvell HPE Microsite. These documents were updated to include not only the new product names that HPE has implemented, but the original model number references as well.

Here are some links to the updated collateral:

Why Marvell FastLinQ for HPE? First, we are a strategic supplier to HPE for I/O technology. In fact, HPE Synergy I/O is based on Marvell FastLinQ technology. Value-add features like storage offload for iSCSI and FCoE and network partitioning are key to enabling HPE to deliver composable network connectivity on their flagship blade solutions.

In addition to storage offload, Marvell provides HPE with unique features such as Universal RDMA and SmartAN® technology. Universal RDMA provides the HPE customer with the ability to run either RoCE RDMA or iWARP RDMA protocols on a single adapter. So, as their needs for implementing RDMA protocols change, there is no need to change adapters. SmartAN technology automatically configures the adapter ports for the proper 10GbE or 25GbE bandwidth, and – based on the type of switch the adapter is connected to and the physical cabling connection – adjusts the forward error correction settings. FastLinQ adapters also support a variety of other offloads including SR-IOV, DPDK and tunneling. This minimizes the impact I/O traffic management has on the host CPU, freeing up CPU resources to do more important work.

Our team of I/O experts stands ready to help you differentiate your solutions based on industry leading I/O technology and features for HPE servers. If you need help selecting the right I/O technology for your HPE customer, contact our field sales and application engineering experts using the Contacts link on our Marvell HPE Microsite.

Living on the Network Edge: Security

By Alik Fishman, Senior Product Marketing Manager, Marvell

Living on the Network Edge: Security

In our series Living on the Network Edge, we have looked at the trends driving Intelligence, Performance and Telemetry to the network edge. In this installment, let’s look at the changing role of network security and the ways integrating security capabilities in network access can assist in effectively streamlining policy enforcement, protection, and remediation across the infrastructure.

Cybersecurity threats are now a daily struggle for businesses experiencing a huge increase in hacked and breached data from sources increasingly common in the workplace like mobile and IoT devices. Not only are the number of security breaches going up, they are also increasing in severity and duration, with the average lifecycle from breach to containment lasting nearly a year1 and presenting expensive operational challenges. With the digital transformation and emerging technology landscape (remote access, cloud-native models, proliferation of IoT devices, etc.) dramatically impacting networking architectures and operations, new security risks are introduced. To address this, enterprise infrastructure is on the verge of a remarkable change, elevating network intelligence, performance, visibility and security2.

COVID-19 has been a wake-up call for accelerating digital transformation – as companies with greater digital presences show more resiliency3. The workforce is expected to transform post-COVID-19 with 20-45%4 becoming distributed and working remotely, either from home or from smaller distributed office spaces. The change in the working environment and accelerated migration to hybrid-cloud and multi-cloud drives a new normal, and the borderless enterprise is now a reality – driving network infrastructure to add end-to-end management, automation and security functionalities needed to support businesses in this new digital era. As mobility and cloud applications extend traditional boundaries and this borderless enterprise becomes increasingly vulnerable, a broader attack surface is no longer contained within well-defined and defended perimeters. Cracks are showing. Remote workers’ identities and devices are the new security perimeter with 70% of all breaches originating at endpoints, according to IDC research5.

This is where embedded security in network access provides essential frontline protection from malicious attacks entry points by enforcing zero-trust access policies. No traffic is trusted from the outset, and the traffic isn’t in the clear within networking devices throughout the infrastructure. Network telemetry and integrated security safeguards capable of inspecting workloads at line-rate team up with security appliances and AI-analytic tools to intelligently flag suspicious traffic and rapidly detect threats. Segmentation of security zones and agile group policy enforcement limits areas of exposure, prevents lateral movement, and enables quick remediation. IEEE 802.1AE MACSec encryption on all ports secure data throughout the network and prevent intrusion. Monitoring control protocol exceptions and activating rate limiters add layers of protection to control and management planes, preventing DDOS attacks. Integrated secure boot and secured storage provide the protection from counterfeit attempts to compromise network hardware and software.

Cybersecurity is now the dominate priorities of every organization, as each adapts to a post-COVID 19 world. Network-embedded security is on the rise to become a powerful ally in fighting the battle against ever evolving security threats. In this dynamic world, what can your network do to secure your assets?

Telemetry: Can You See the Edge?

By Suresh Ravindran, Senior Director, Software Engineering

Telemetry: Can You See the Edge?

So far in our series Living on the Network Edge, we have looked at trends driving Intelligence and Performance to the network edge. In this blog, let’s look into the need for visibility into the network.

As automation trends evolve, the number of connected devices is seeing explosive growth. IDC estimates that there will be 41.6 billion connected IoT devices generating a whopping 79.4 zettabytes of data in 20251. A significant portion of this traffic will be video flows and sensor traffic which will need to be intelligently processed for applications such as personalized user services, inventory management, intrusion prevention and load balancing across a hybrid cloud model. Networking devices will need to be equipped with the ability to intelligently manage processing resources to efficiently handle huge amounts of data flows.

How do you see what you can’t see?

But is your network edgy enough? In order to handle the growth, we’ve seen intelligence pushed to the network edge for application-aware engineering and inferencing applications running in hybrid clouds. In order to keep up with billions of mobile devices using denser applications, we addressed wireless offloading as one method to alleviate the burden on cellular networks. This approach increases the load on edge and enterprise networks with demands for intelligent flow processing capabilities to efficiently utilize the LAN and WAN bandwidth.   With intelligence and performance in place, we also need to address the growing complexity associated with “seeing” how network switching resources are being utilized. Visibility through network telemetry is fundamental to empowering AI-automation, performance, security and troubleshooting. To be proactive and predictive, networks need to be built with switches that look beyond the obvious with intelligent telemetry capabilities.

Intelligent telemetry for effective network visibility

Increased use of analytics and AI for performance monitoring, detection, troubleshooting and response has been ranked a top priority for organizations to achieve their vision of the ideal networkIT professionals leverage telemetry to define workload behaviors requiring network bandwidth timing patterns and whether applications are causing jitter or low-bandwidth issues. In general, telemetry functions have tracked events in hindsight but are now increasingly used to analyze and predict – living on the network edge means monitoring, predicting and managing the anomalies for proactive infrastructure automation and application responses.

An effective telemetry solution also requires network devices to stream a wide range of metadata for network flow and switch resource usage in real time. As streaming telemetry header formats evolve, it is equally important for the switch silicon’s pipeline to have programming abilities which adapt to changes in telemetry tools while performing at line-rate.   

Successfully living at the network edge means detecting and adjusting algorithms in real time. It won’t be enough to move intelligence to the edge and increase the performance for workloads if you can’t see what is happening within the network. Network visibility is crucial in managing workloads to reliably deliver customer and enterprise service level agreements predictively. Telemetry, Intelligence and Performance are critical technologies for the growing borderless campus as mobility and cloud applications proliferate and drive networking functions. In our next blog, we will discuss Security as part of our insights and TIPS to Living on the Network Edge.  Watch out for the edge …

The Need for Speed at the Edge

By George Hervey, Principal Architect, Marvell

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.

Wireless Offload

How do networks with dense wireless connections address the overwhelming bandwidth and connection challenges? One answer is wireless offload. Whether a big box retail store with 1,000 customers or a 60,000-seat stadium or a convention center with 200,000 attendees, the amount of data to be delivered is enormous. The cost to carry the data over wireless has hit a critical inflection point in capacity, driving the need for offload to a wired network. This trend of wireless offload requires higher and higher performance at the network edge enabling users to experience high-performance connectivity and low latency response times they’ve grown to expect.

New Performance Paradigm

Deployment of 5G and Wi-Fi 6 are enabled by advanced wireless access technologies including the use of MIMO and higher frequency spectrum. The capacity being delivered will quickly be consumed by the growing number of devices and new applications. In fact, higher bandwidth at the access layer was a major force behind the definition of Multi-Gig Ethernet. This new performance paradigm will have an impact on all layers of the network, motivating an increase in uplink port speeds to handle the added access bandwidth. Additionally, stacking link capacity will increase to facilitate efficient port deployments and help handle the growth in attached clients.

Network capacity increases enable the adoption of higher bandwidth services, support for emerging real-time applications and an expansion of concurrent active devices on networks. Ironically, the resulting trends and future innovations will continue to drive the need for increased network performance.

Performance is the second part in a series of TIPS that will discuss essential technologies for the growing borderless campus as mobility and cloud applications proliferate and drive networking functions. Telemetry challenges and insights will inspire our next TIPS to Living on the Network Edge.

Driving Network Intelligence and Processing to the Edge

By George Hervey, Principal Architect, Marvell

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.

The Need for Intelligence at the Edge
Network connectivity and traffic growth continue to increase as the rate of adoption of new data-intensive applications drive bandwidth requirements and a smarter infrastructure — an infrastructure that can, through intelligence, recognize specific application and infrastructure needs and deliver processing at the edge when necessary. While network speeds increase with advancements of multi-gigabit Ethernet and 400GE backbone connections, the bandwidth available with the latest 5G and Wi-Fi will continue to cause a bottleneck in the backhaul. Edge processing helps prevent the need for moving massive amounts of data across networks. This higher level of network intelligence allows the network to deliver complex software-defined infrastructure management without user intervention, manage inference engines, apply policies, and most importantly, deliver proactive application functionality. This enhances the user experience by offering a near real-time interactive platform with low latency, high reliability and secure infrastructure.

With bandwidth demand growing so much, how do we address it at scale? If we parallel the cloud data centers, we see that one way to scale out and handle the added bandwidth and number of nodes is to add processing to the edge of the network. This was accomplished in data centers through the use of smartNICs to offload complex processing tasks including packet processing, security and virtualization from the servers. A similar approach is being achieved in the carrier networks through the deployment of SD-WAN/uCPE/vCPE appliances placed at the edge to provide the intelligence alongside reduced connectivity costs. However, this approach becomes problematic in enterprise networks where a variety of end point capabilities are needed, and the first location of uniformity takes place at the network’s access layer.

Taking Advantage of Artificial Intelligence (AI)
Yet another challenge is created when legacy methods are used for deploying services in enterprise networks – such as centralized firewalls and authentication servers. With the expected increase in devices accessing the network and more bandwidth needed per device, these legacy constraints can result in bottlenecks. To address these issues, one must truly live on the network edge, pushing out the processing closer to the demand and making it more intelligent. Network OEMs, IT infrastructure owners and service providers will need to take advantage of the new generations of artificial intelligence (AI) and network function offloads at the access layer of the enterprise network.

TIPS to Living on the Network Edge
This is the first in a series providing TIPS about essential technologies that will be needed for the growing borderless campus as mobility and cloud applications proliferate and move networking functions from the core to the edge. Today, we discussed the trend toward expanded Network Intelligence. In Part 2, we will look at the Performance levels needed as we provide more insights and TIPS to Living on the Network Edge.

Enhanced Wireless Microcontroller Enables Affordable Design

By Sree Durbha, Head of Smart-Connected Business, Marvell

Today, we are at the peak of technology product availability with the releases of the new iPhone models, Alexa enabled devices and more. In the coming days, there will be numerous international consumer OEMs preparing new offerings as we approach the holiday selling season. Along with the smartphones, voice assistant enabled smart speakers and deep learning wireless security cameras, many devices and appliances are increasingly geared toward automating the home, the office and the factory. These devices are powered by application microcontroller units (MCUs) with embedded wireless connectivity to help users to remotely control and operate them via phone apps, voice or even through mere presence. This is part of an industry trend of pushing intelligence into everyday things. According to analyst firm Techno Systems Research1, this chipset market grew by more than 60% over the course of the last year and is likely to continue this high rate of growth.

The democratization of wireless connectivity intellectual property and the continuing shift of semiconductor design and development to low cost regions is helping give rise to new industry players. In order to help customers differentiate in this highly competitive market, Marvell has announced the 88MW320/322 low-power Wi-Fi microcontroller SoC. This chipset is 100% pin-compatible and software compatible with the existing 88MW300/302 based designs. Although the newly released microcontroller is cost-optimized, there are several key hardware and software enhancements in this chipset.

Support for extended industrial temperature operation, from -400 C through to 1050 C has been added. Unlike its predecessor, the 88MW320/322 can be implemented into more challenging application areas – such as LED lighting and industrial automation. No RF specific changes have been made within the silicon, so the minimum and maximum RF performance parameters remain the same as before. However, other fixes made have helped improve typical RF performance as reported by some of our customers when evaluating samples. Since there was no change in form, fit or function, the external RF interface remains the same as well. This enables customers to leverage existing 88MW300/302 module and device level regulatory certification on 88MW320/322. A hardware security feature has also been incorporated that allows customers to uniquely tie the chipset to the firmware running on it. This helps prevent counterfeit software to run on the chipset.

This chipset is supported by the industry-leading Marvell EZ-Connect SDK for Apple’s new Advanced Development Kit (ADK) and Release 13 HomeKit Accessory Protocol SDK (R13 HAPSDK) with software-based authentication (SoftAuth), Amazon’s AWS IoT and other third-party cloud platforms. The Apple SoftAuth support now allows customers to avoid the cost and hassle of adding the MFi authentication chip, which was previously required to get HomeKit certification. On the applications side, we have added support for the Alexa Voice Services library. With MP3 decoder and OAUTH2 modules integrated on our SDK, our solution now allows customers to add an external audio-codec chipset to offer native voice command translation for basic product control functions.

As previously announced, we continue to partner with Dialog Semiconductor to offer support for BLE with shared antenna managed coexistence software with our Wi-Fi on 88MW320/322. Several of our module vendor partners have announced support for this chipset in standalone and Wi-Fi + BLE combo configurations. You can find a complete list of modules supporting this chipset on the Marvell Wireless Microcontrollers page.

The 88MW320/322 has been sampling to customers for a few months now and is currently shipping. The product comes in 68-pin QFN package (88MW320) and 88-pin QFN package (88MW322) formats. It is available in commercial, extended, industrial and extended industrial temperature ranges in both tray and tape and reel configurations.

Watch this space for future announcements as we extend the availability of Marvell’s solutions for the smart home, office and factory to our customers through our catalog partners. The goal is to enable our wireless microcontroller solutions with easy to install one-click software that allows smaller customers to use our partner reference designs to develop their form factor proof of concept designs with hardware, firmware, middleware, cloud connectivity software, collateral and application support from a single source. This will free up their resources so that they can focus on what is most important to them – which is to work on application software and differentiation.

The best is yet to come. As the industry demands solutions with higher levels of integration at ever lower power to allow for wireless products with several months and even years of battery life, you can count on Marvell to innovate to help meet customer needs. For example, the 802.11ax standard specification is not just for high efficiency and high throughput designs, it also offers provisions for low power, long battery life designs. 20MHz only channel operation in the 5GHz band and features such as target wake time (TWT), which helps extend the sleep cycle of devices; dual sub-carrier modulation (DCM), which helps extend the wireless range; uplink and downlink OFDMA, all contribute to make the next generation of devices worth waiting for.
