New Data center switches spell new possibilities

New Switches & Routers Spell New Possibilities 

The hyperscale, cloud and hyper converged industry — despite a pause in data center equipment growth in Q1, as we reported last week—  saw two major Ethernet product announcements so far this month. 
 
Both new platforms, announced by Mellanox and Arista respectively, are supercharged to take the data center to the next level. They play into all of the big trends of cloud hosted, mass virtualization and automation of trouble shooting through telemetry.  They also seem to set some new performance records.




Details: 
First there is Mellanox, unveiling this week its “Ethernet Cloud Fabric” (aka ECF) new switches underpinned by its  Spectrum2 chipset. Mellanox is emphasizing automated troubleshooting with telemetry, support of virtualization, scale to 400GbE, and a fully shared buffer architecture for improved performance in hyper scale cloud environments.

Mellanox ECF Platform Highlights:
  • Mellanox “What Just Happened” (WJH) Telemetry: Offers improved visibility as to the root cause of network/server problems while reducing the amount of telemetry data that needs to be stored.
  • Spectrum2 chipset, developed in house, has a fully shared buffer architecture for better microburst absorption. The new switches fairly and predictably divide traffic between servers. 
    • Fairness is an issue for ESF and ECF use cases.  It is found in Hadoop, CEPH, and SAP environments. This is where fair and predictable performance matters. 
    •  For ECF in clouds. You have to stop one tenant from robbing resources of others, whereas neighboring tenants might get robbed of another performance. 
  • Virtualization:  Mellanox makes better spine switches with increased visibility, performance and virtualization support of VXLANs.   
  • 200 Gigabit: The 200GbE switches will be useful for high speed applications like Machine Learning and NVMEoF.  
  • 200GbE will also be deployed in volume by hyperscaler / social media companies. Some large customers prefer 200G over 400G for the larger radix as it can eliminate a switching tier in a large data center

ECF Performance:
  • 8.33 Billion Packets per second 
  • 42MB Monolithic and fully shared packet buffer to provide high bandwidth and low-latency cut-through performance
  • Robust RoCE Datapath to enable hardware accelerated data movement for Ethernet Storage Fabric and Machine Learning applications
  • Half a million flexible forwarding entries to support large Layer-2 and Layer-3 networks


Next is the announcement from stalwart cloud player Arista, and it has delivered its own new products, its' R3 Series routing platforms. The emphasis is on massive throughput, density, power efficiency and price performance. 



R3 Platform Highlights
  • Throughput: Packet processing offers 8X the throughput of the previous generation R1 Series and 5X the throughput of the R2 Series. 
  • 400G Ethernet: high-density 400G ports across all platforms to support these next-generation networks.
  • New Capabilities: New R3 packet processing silicon offers significant enhancements in route scale, security and telemetry. .
  • Wide Range of Form Factors: The new R3 Series comes in a wide range of form factors, including four fixed form factors, an upgrade to our award winning 7500 family, and the brand new 7800 modular chassis with up to 460 Tbps capacity per chassis

Key Capabilities 
  • The Arista 7280R3 delivers unparalleled Performance with Dynamic Deep Buffers and VOQ for Lossless forwarding
  • Flexible design choices for 10G/25G/40G/50G/100G and 400G
  • FlexRoute™ and EOS NetDB™ for internet peering with high density and low power
  • Embedded Accelerated sFlow and IPFIX for high capacity network security and application monitoring
  • Flexible pipeline for programmable features including Algorithmic ACLs and Inband Network Telemetry for flow and packet forensic

open19 summit - The Foundation expects 2019 to be the year of deployments

5/16/2019

0 Comments

 
We attended the Open19 Foundation Summit 2019 in San Jose, CA.  The key message of the leadership team of the Foundation was that it expects 2019 to be the year where Open19 systems begin shipping.  Yuval Bachar, President of the Foundation explained that there are 8-10 companies that are deploying or seriously considering, including two mega data center operators in process of evaluation and at least 6 adopters in advanced evaluation/deployment.  Open19 does not specify what technology will be inside the systems; it only defines the form factor.  Interestingly, GPU and ARM designs are included and we heard about AMD CPU more often than we did Intel.  
 
VaporIO made a presentation about its edge data center systems.  Matt Trifiro, CMO of VaporIO explained that its systems nominally consume up to 165 kw in a 9 foot round datacenter.  It claims that Vapor IO is deploying in 6 cities, 3 to 4 data centers in each city.
ASUS and a new company, German Edge Cloud, both made interesting presentations.  Salim Fedel, Associate VP Enterprise Solutions Business Group, ASUS, presented a few of the company's Open19 oriented products, Alps19, Brick and its Network Switch.  Jason Rylands, VP of Data Center Strategy & International Sales, German Edge Cloud, made a very interesting presentation about its company's activities in Germany on how it is participating in the manufacturing industry in Germany.  There is reticence on putting manufacturing data and control on the cloud, but there is a desire to build a German-only computing system, driven in part by GDPR and part by the nation's focus on manufacturing - that's the opportunity.  German Edge Cloud has decided to use Open19 systems - accessing only the front of the racks is a big deal, it believes.
German Edge Cloud shared many examples of how it is engaging with manufacturers for real-time error tracking during the manufacturing process, using analytics, and sharing information between various companies in the German supply chain.

Keysight World San Francisco Update on 5G and Pervasive Ethernet

​We attended media briefings at the Keysight World conference held near San Francisco, California, yesterday.  Keysight World San Francisco showed a more integrated Ixia as well as a further push towards 5G, automotive and energy, and data center and telecom.  Much of the companies conversations during the event related to synergies between these technologies.  Such as how to push the automotive industry forward using 5G and the need for edge computing in 5G.  As Keysight is involved at the beginning of the launches of many new cellular technologies, it has good insights into the timeline and progress of the 5G market.

One of our key takeaways from the show is the increased pervasiveness of Ethernet in the telecom and automotive industry as well as the significant increase in constant data creation.  All this data will need robust, and more intelligent networks to transport it.  We were also impressed that Keysight World will actually take place in 10 cities around the world, with San Francisco being the first.

Another interesting observation was just how global Keysight was in looking at products, for example in one session that we attended, much of the automotive effort in the company was located in Germany.

Huawei's revenues are at risk as US puts Chinese Tech giant on its "Entity List"

5/15/2019

0 Comments

 
According to news reports and press and social media announcements by high-ranking members of US government, the US government has put Huawei on its so-called "Entity List" of the Bureau of Industry and Security (BIS).  Our read on this is it similar to what happened with ZTE during C2Q18 last year, a move that severely curtailed ZTE's shipments and revenue until ZTE made concessions and was removed from the list.  Many, but not all, Huawei products use technology only available from US suppliers. US-made semiconductors are the most significant Entity List target that Huawei needs to ship its products.  Significant US semiconductor suppliers to Huawei include Intel, Xilinx, and Broadcom.  

Huawei is such a significant vendor in many of our coverage areas, including Mobile Radio Access Networks (RAN), Ethernet Switching, and Servers, for instance, that we feel it is a good time to point out that 2019 market-level estimates may be at risk.  Additionally, since Chinese cloud services players, like Baidu, Alibaba and Tencent cannot delay their capital infrastructure build-outs, alternate suppliers may benefit.

We think it comes as no surprise to Huawei that the US is putting it under pressure.  Just over a year ago, we attended the Huawei analyst summit (April 16, 2018) and its then-chairman said in response to the question "Will Huawei find alternate suppliers for data center products, "Today, Intel is the dominant player.  Our point of view, we look forward to a more diversified landscape; but we work with Intel mainly now."  Additionally, at Huawei's most recent analyst summit (mid-April 2019), the three main keynote speakers, all high-ranking executives of the company spoke about how much progress Huawei has made in developing in-house semiconductors and what its plans are to continue developing more.  We do, however, think that despite Huawei's diversification efforts that it still has significant reliance upon key US chip companies.
