Marvell Powers HPE Servers with Next-Generation Ethernet Technology

By Todd Owens, Technical Marketing Manager, Marvell

Data is the new currency for many businesses today.  The ability to access, analyze and act on data has become a competitive advantage for many companies.  While much attention is paid to the storage devices and compute required to optimize data processing, the I/O infrastructure is often overlooked.  The reality is that I/O technologies are just as important as the core count of the CPU or storage capacity and latency of the storage array.  The time is now to future-proof your network and that’s where Marvell is here to help.

Marvell has been a long-time Hewlett Packard Enterprise (HPE) supplier of I/O technology used in the HPE ProLiant, Apollo, HPE Synergy, and HPE Storage offerings.  Over the past year, a new generation of Ethernet I/O has begun making its way into these HPE platforms.  Based on Marvell® FastLinQ® QL41000 and QL45000 Ethernet technology, these new adapters are allowing HPE customers to “future-proof their network” connectivity for what’s to come in the near future of data centers.

The QL41000 and QL45000 adapter technology provides several new capabilities not found in other I/O offerings for HPE.  Advancements include:

  • Universal RDMA – provides customers with flexibility through concurrent support for both RDMA over Converged Ethernet (RoCE) and iWARP RDMA protocols on the same adapter.
  • SmartAN™ Technology – enables auto-negotiation for transitioning from 10GbE to 25GbE connections. SmartAN automatically configures the adapter for bandwidth and error code correction based on the cabling configuration and switch port settings the adapter is connected to.
  • Storage Offload – Converge Network Adapter offerings include full hardware offload for iSCSI and FCoE protocols which greatly reduces the CPU resources required for transmitting storage traffic compared to the use of software initiators.

 

These are in addition to enhanced DPDK performance (up to 36Mpps bi-directional) and support for SR-IOV, TCP/IP stateless offloads, IEEE 1588 time stamping and more.

The FastLinQ 41000 series technology can be found in next-generation Flexible LOM Rack (FLR) and standup PCIe adapters for HPE ProLiant and Apollo servers.
Models include:

  • HPE Ethernet 10Gb 521-T Adapter
  • HPE Ethernet 10Gb 524SFP+ Adapters
  • HPE Ethernet 10/25Gb 621SFP28 Adapter
  • HPE Ethernet 10/25Gb 622FLR CNA
  • HPE StoreFabric 10Gb CN1200-T CNA
  • HPE StoreFabric 10/25Gb CN1300R CNA

These adapters allow HPE Server customers to future-proof their Rack and Tower servers with RDMA for use in Hyper-Converged Infrastructure (HCI) and Software Defined Storage (SDS) solutions; and make the transition from 10GbE to 25GbE connectivity seamless at the server.  These I/O devices are ideal for customers considering Microsoft Azure Stack HCI or VMware vSAN environments, or the deployment of any latency sensitive application.

The FastLinQ 45000 series technology can be found in next-generation mezzanine adapters for HPE Synergy, including:

  • HPE Synergy 10/20/25Gb 4820C Adapter
  • HPE Synergy 25/50GbE 6810C Adapter

With Universal RDMA support improved DPDK performance and high-bandwidth capability, these adapters are ideal for customers with VMware ESXi or Microsoft Hyper-V deployments, and for Telco or high-frequency trading applications.

Since many applications today will start to require more I/O performance and low latency RDMA, HPE’s next-gen Ethernet adapters will go a long way in future proofing networking connectivity for server customers.

RoCE or iWARP for Low Latency?

By Todd Owens, Technical Marketing Manager, Marvell

Today, Remote Direct Memory Access (RDMA) is primarily being utilized within high performance computing or cloud environments to reduce latency across the network.  Enterprise customers will soon require low latency networking that RDMA offers so that they can address a variety of different applications, such as Oracle and SAP, and also implement software-defined storage using Windows Storage Spaces Direct (S2D) or VMware vSAN.  There are three protocols that can be used in RDMA deployment: RDMA over InfiniBand, RDMA over Converged Ethernet (RoCE), and RDMA over iWARP.  Given that there are several possible routes to go down, how do you ensure you pick the right protocol for your specific tasks?

In the enterprise sector, Ethernet is by far the most popular transport technology.  Consequently, we can ignore the InfiniBand option, as it would require a forklift upgrade to the I/O existing infrastructure – thus making it way too costly for the vast majority of enterprise data centers.  So, that just leaves RoCE and iWARP.  Both can provide low latency connectivity over Ethernet networks.  But which is right for you?

Let’s start by looking at the fundamental differences between these two protocols.  RoCE is the most popular of the two and is already being used by many cloud hyper-scale customers worldwide.  RDMA enabled adapters running RoCE are available from a variety of vendors including Marvell.

RoCE provides latency at the adapter in the 1-5us range but requires a lossless Ethernet network to achieve low latency operation.  This means that the Ethernet switches integrated into the network must support data center bridging and priority flow control mechanisms so that lossless traffic is maintained.  It is likely they will therefore have to be reconfigured to use RoCE.  The challenge with the lossless or converged Ethernet environment is that configuration is a complex process and scalability can be very limited in a modern enterprise context.

Now it is not impossible to use RoCE at scale but to do so requires the implementation of additional traffic congestion control mechanisms, like Data Center Quantized Congestion Notification (DCQCN), which in turn calls for large, highly-experienced teams of network engineers and administrators.  Though this is something that hyper-scale customers have access to, not all enterprise customers can say the same.  Their human resources and financial budgets can be more limited.

Going back through the history of converged Ethernet environments, one must look no further than Fibre Channel over Converged Ethernet (FCoE) to see the size of the challenge involved.  Five years ago, many analysts and industry experts claimed FCoE would replace Fibre Channel in the data center.  That simply didn’t happen because of the complexity associated with using converged Ethernet networks at scale.  FCoE still survives, but only in closed environments like HPE BladeSystem or HPE Synergy servers, where the network properties and scale are carefully controlled.  These are single-hop environments with only a few connections in each system.

Finally, we come to iWARP.  This came on the scene after RoCE and has the advantage of running on today’s standard TCP/IP networks.  It provides latency at the adapter in the range of 10-15us.  This is higher than what one can achieve by implementing RoCE but is still orders of magnitude below that of standard Ethernet adapters.

They say, if all you have is a hammer, then everything looks like a nail.  That’s the same when it comes to vendors touting their RDMA-enabled adapters.  Most vendors only support one protocol, so of course that is the protocol they will recommend.  Here at Marvell, we are unique in that with our Universal RDMA technology, a customer can use both RoCE and iWARP on the same adapter.  This gives us more credibility when making recommendations and means that we are effectively protocol agnostic.  It is really important from a customer standpoint, as it means that we look at what is the best fit for their application criteria.

So which RDMA protocol do you use when?  Well, when latency is the number one criteria and scalability is not a concern, the choice should be RoCE.  You will see RoCE implemented as the back-end network in modern disk arrays, between the controller node and NVMe drives.  You will also find RoCE deployed within a rack or where there is only one or two top-of-rack switches and subnets to contend with.  Conversely, when latency is a key requirement, but ease-of-use and scalability are also high priorities, iWARP is the best candidate.  It runs on the existing network infrastructure and can easily scale between racks and even long distances across data centers.   A great use case for iWARP is as the network connectivity option for Microsoft Storage Spaces Direct implementations.

The good news for enterprise customers is that several Marvell® FastLinQ® Ethernet Adapters from HPE support Universal RDMA, so they can take advantage of low latency RDMA in the way that best suits them.  Here’s a list of HPE Ethernet adapters that currently support both RoCE and iWARP RDMA.

With RDMA-enabled adapters for HPE ProLiant, Apollo, HPE Synergy and HPE Cloudline servers, Marvell has a strong portfolio of 10Gb or 25GbE connectivity solutions for data centers.  In addition to supporting low latency RDMA, these adapters are also NVMe-ready.  This means they can accommodate NVMe over Ethernet fabrics running RoCE or iWARP, as well as supporting NVMe over TCP (with no RDMA).  They are a great choice for future-proofing the data center today for the workloads of tomorrow.

Redefining the Connected Home

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

The concept of a fully ‘connected home’ has been discussed for more than 20 years. However, widespread proliferation has taken far longer than anyone could have originally imagined. For a long time, deployment activity seemed to be limited to a relatively small number of high value installations. These installations were generally complicated to implement and their operation was not very user-friendly. Most importantly, they were composed of an amalgamation of isolated subsystems from different suppliers rather than a single universal system.

Even as home automation started to become accessible from smartphones and tablets, market fragmentation meant that each aspect of the automation technology installed within a home was still based on its own proprietary mechanism that needed a separate app to control it. As a result, home automation systems have often proven inconvenient and frustrating for those operating them and has unquestionably held back their adoption by consumers. The industry fragmentation and lack of interoperability between different vendor ecosystems meant that the consumer couldn’t really take advantage of the connected capabilities of all the various platforms.

The industry is innovating with solutions that seem finally likely to help broaden the appeal of home automation and accelerate its future progression. Through its HomeKit™ technology, Apple is looking to consolidate all the various verticals under a single, comprehensive home automation ecosystem that works together easily and securely. The HomeKit Accessory Protocol (HAP) is enabling hardware from different suppliers involved in home automation to communicate with Apple products (iPhone, iPad, Apple Watch) via a single, consistent, complete platform. This is done via wireless technologies like Bluetooth® Low Energy technology, as well as IP connectivity. The list of different ‘behaviors’ covered by the HomeKit hardware and software technology is extensive. Selecting a playlist for the audio system, turning on the lights in a particular room, remotely starting up home appliances (such as a washer/dryer), adjusting the heating and cooling, and activating the door entry system are just a few examples. But, because all of these functions are controlled via the Apple Home app or by asking Siri (rather than multiple apps), they can now work in tandem. For instance, settings can be configured so that if the curtains in a room were drawn, then the lighting would simultaneously turn on, or the ambient lighting could be changed to fit a certain music playlist.

Marvell is placing itself at the forefront of next generation smart home development through its support of Apple HomeKit. Our family of wireless SoC devices was the first in the industry to secure certification for the original HAP specification three years ago and has consistently been at the forefront as evidenced with our latest HomeKit Accessory Protocol Release 9 (HAP R9) specification. The low power 88MW30x ICs each possess an integrated microcontroller with Cortex®-M4 processing core, plus single-band IEEE 802.11n Wi-Fi® functionality. The truly transformational change this time is our SoCs’ certification for iCloud implementation, which enables remote control of HomeKit compliant devices using voice as well as the HomeKit App using iCloud® remote access. This means that OEMs serving the home automation market will be able to make their systems much more streamlined and convenient to seamlessly implement through iCloud. As a result, new use cases are now possible. For example, you can remotely start your thermostat to heat or cool your home using the Apple Home app (or Siri® voice control) while you are still on your way home from work and have the right temperature set for when you arrive.

This technology is showcased in the Marvell® EZ-Connect® HAP software development kit (SDK), which is designed to facilitate the implementation of HomeKit-enabled home automation accessories – accelerating our OEM customers’ design cycles and allowing products to be brought to market more quickly. Complementing its 802.11n wireless connectivity, the incorporated bridging functionality also allows interfacing with equipment using other RF protocols like Bluetooth low energy technology. For example, Marvell has partnered with a leading Bluetooth low energy vendor to offer a combo module reference design that is commercially available today through one of our module vendor partners, Azurewave. Our emphasis on security, encryption and memory partitioning allows secure, over-the-air firmware upgrades so that customer applications can run securely from external Flash memory while being encrypted on the fly. Our SDK also supports Amazon’s popular AWS cloud platform and Google’s Weave/Cloud as alternatives. To accompany the SDK, Marvell intends to provide OEMs with all the collateral necessary to get their products through the HomeKit certification process as rapidly and painlessly as possible and into the market quickly. Useful project examples are also provided.

Marvell understands how crucially important a robust software solution is to enable a hassle free home automation user experience and has developed industry leading software capabilities in support of Apple HomeKit. This has allowed us to get ahead of the game.
