New Dell EMC 100 GbE switch tailored for east-west traffic

Dell EMC has introduced a high-density 100 Gigabit Ethernet switch aimed at service providers and large enterprises that need more powerful hardware to support a growing number of cloud applications and digital business initiatives.

Dell EMC launched the Z9264F open networking switch this week, listing its target customers as hyperscale data center operators, tier-one  and -two service providers and enterprises. The Dell EMC 100 GbE switch is designed for leaf-spine switching architectures.

“Dell’s new, high-performance, low-latency 100 GbE switch is ideally suited for large enterprises and service providers,” said Rohit Mehra, analyst at IDC. “The continued growth of cloud applications that require high-performance, east-west traffic-handling capabilities will likely be one of the key drivers for this class of switches to see increased traction.”

Indeed, Dell EMC, Cisco, Hewlett Packard Enterprise (HPE) and Juniper Networks are counting on an increase in data center traffic to sell their 100 GbE switches. So far, demand for the hardware has been robust. In the first quarter, revenue from 100 GbE gear grew nearly 84% year over year to $742.5 million, according to IDC. Port shipments increased almost 118%.

The Dell EMC 100 GbE switch is 2RU hardware available with 64, 128 or 64 ports of 100 GbE, 25 GbE or 50 GbE, respectively. Options for 10 GbE and 40 GbE ports are also available. Broadcom’s 6.4 Tbps StrataXGS Tomahawk II chip powers the switch.

Dell EMC, along with rival HPE, is marketing its support for third-party network operating systems as a differentiator for its switches. Dell EMC is selling the Z9246F with the enterprise edition of its network operating system (NOS), called OS10, or with operating systems from Big Switch Networks, Cumulus Networks, IP Infusion or Pluribus Networks.

Other options for the Dell 100 GbE switch include the open source edition of OS10 and either the Metaswitch network protocol stack or the Quagga suite of open source applications for managing routing protocols. Finally, Dell EMC will sell just the hardware with several open source applications, including Quagga and the OpenSwitch or SONiC NOS.

The starting price for the Z9264F, without an operating system or optics, is $45,000.

Trends in the 100 GbE market

While open networking is not mainstream yet in the enterprise, providing choice in terms of the complete hardware and software stack is something that large enterprises and service providers have started to look at favorably.

Several trends are driving the 100 GbE market. Service providers are redesigning their data centers to support software-based network services, including 5G and IoT. Also, financial institutions are providing services to customers over a growing number of mobile devices.

Meanwhile, cloud companies that provide infrastructure or platform as a service are buying more hardware to accommodate a significant increase in companies moving application workloads to the cloud. In 2017, public cloud data centers accounted for the majority of the $46.5 billion spent on IT infrastructure products — server, storage and switches — for cloud environments, according to IDC.

In the first quarter, original design manufacturers accounted for almost 30% of all infrastructure hardware and software sold to public cloud providers, according to Synergy Research Group, based in Reno, Nev. Dell EMC had a 5% to 10% share, which was the same size share as Cisco and HPE.

As a switch supplier, Dell EMC is a smaller player. The company is not one of the top five vendors in the market, according to IDC. Nevertheless, Dell EMC is a major supplier of open networking to the small number of IT shops buying the technology.

“While open networking is not mainstream yet in the enterprise, providing choice in terms of the complete hardware and software stack is something that large enterprises and service providers have started to look at favorably,” Mehra said.

Big Switch taps AWS VPCs for hybrid cloud networking

Big Switch Networks has introduced software that provides consistency in building and managing a network infrastructure within a virtual network in Amazon Web Services and the private data center.

The vendor, which provides a software-based switching fabric for open hardware, said this week it would release the hybrid cloud technology in stages. First up is a software release next month for the data center, followed by an application for AWS in the fourth quarter.

The AWS product, called Big Cloud Fabric — Public Cloud, provides the tools for creating and configuring a virtual network to deliver Layer 2, Layer 3 and security services to virtual machines or containers running on the IaaS provider. AWS also offers tools for building the virtual networks, which it calls Virtual Private Clouds (VPCs).

In general, customers use AWS VPCs to support a private cloud computing environment on the service provider’s platform. The benefit is getting more granular control over the virtual network that serves sensitive workloads.

Big Cloud Fabric — Public Cloud lets companies create AWS VPCs and assign security policies for applications running on the virtual networks. The product also provides analytics for troubleshooting problems. While initially available on AWS, Big Switch plans to eventually make Big Cloud Fabric — Public Cloud available on Google Cloud and Microsoft Azure.

VPCs for the private data center

For the corporate data center, Big Switch plans to add tools to its software-based switching fabric — called Big Cloud Fabric — for creating and managing on-premises VPCs that operate the same way as AWS VPCs, said Prashant Gandhi, the chief product officer for Big Switch, based in Santa Clara, Calif.

Customers could use the on-premises VPCs, which Big Switch calls enterprise VPCs, as the virtual networks supporting computing environments that include Kubernetes and Docker containers, the VMware server virtualization vSphere suite, and the OpenStack cloud computing framework.

“With the set of tools they are announcing, [Big Switch] will be able to populate these VPCs and facilitate a consistent deployment and management of networks across cloud and on premises,” said Will Townsend, an analyst at Moor Insights & Strategy, based in Austin, Texas.

Big Switch already offers a version of its Big Monitoring Fabric (BMF) network packet broker for AWS. In the fourth quarter, Big Switch plans to release a single console, called Multi-Cloud Director, for accessing all BMF and Big Cloud Fabric controllers.

In general, Big Switch supplies software-based networking technology for white box switches. Big Cloud Fabric competes with products from Cisco, Midokura and Pluribus Networks, while BMF rivals include technology from GigamonIxia and Apcon.

Big Switch customers are mostly large enterprises, including communication service providers, government agencies and 20 Fortune 100 companies, according to the vendor.

Experts skeptical an AWS switch is coming

Industry experts said AWS has no need to build and sell a white box data center switch as reported last week but could help customers by developing a dedicated appliance for connecting a private data center with the public cloud provider.

The Information reported last Friday AWS was considering whether to design open switches for an AWS-centric hybrid cloud. The AWS switch would compete directly with Arista, Cisco and Juniper Networks and could be available within 18 months if AWS went through with the project. AWS has declined comment.

Industry observers said this week the report could be half right. AWS customers could use hardware dedicated to establishing a network connection to the service provider, but that device is unlikely to be an AWS switch.

“A white box switch in and of itself doesn’t help move workloads to the cloud, and AWS, as you know, is in the cloud business,” said Brad Casemore, an analyst at IDC.

What AWS customers could use isn’t an AWS switch, but hardware designed to connect a private cloud to the infrastructure-as-a-service provider, experts said. Currently, AWS’ software-based Direct Connect service for the corporate data center is “a little kludgy today and could use a little bit of work,” said an industry executive who requested his name not be used because he works with AWS.

“It’s such a fragile and crappy part of the Amazon cloud experience,” he said. “The Direct Connect appliance is a badly needed part of their portfolio.”

AWS could also use a device that provides a dedicated connection to a company’s remote office or campus network, said John Fruehe, an independent analyst.  “It would speed up application [service] delivery greatly.”

Indeed, Microsoft recently introduced the Azure Virtual WAN service, which connects the Azure cloud with software-defined WAN systems that serve remote offices and campuses. The systems manage traffic through multiple network links, including broadband, MPLS and LTE.

Connectors to AWS, Google, Microsoft clouds

For the last couple of years, AWS and its rivals Google and Microsoft have been working with partners on technology to ease the difficulty of connecting to their respective services.

In October 2016, AWS and VMware launched an alliance to develop the VMware Cloud on AWS. The platform would essentially duplicate on AWS a private cloud built with VMware software. As a result, customers of the vendors could use a single set of tools to manage and move workloads between both environments.

A year later, Google announced it had partnered with Cisco to connect Kubernetes containers running on Google Cloud with Cisco’s hyper-converged infrastructure, called HyperFlex. Cisco would also provide management tools and security for the hybrid cloud system.

Microsoft, on the other hand, offers a hybrid cloud platform called the Azure Stack. The software runs on third-party hardware and shares its code, APIs and management portal with Microsoft’s Azure public cloud to create a common cloud-computing platform. Microsoft hardware partners for Azure Stack include Cisco, Dell EMC and Hewlett Packard Enterprise.

Juniper adds core campus switch to EX series

Juniper Networks has added to its EX series a core aggregation switch aimed at enterprises with campus networks that are too small for the company’s EX9000 line.

Like the EX9000 series, the EX4650 — a compact 25/100 GbE switch — uses network protocols typically found in the data center. As a result, the same engineering team can manage the data center and the campus.

“If an enterprise has a consistent architecture and common protocols across networks, it should be well-placed to achieve operational efficiencies across the board,” said Brad Casemore, an analyst at IDC.

The network protocols used in the EX4650 and EX9000 are the Ethernet VPN (EVPN) and the Virtual Extensible LAN (VXLAN). EVPN secures multi-tenancy environments in a data center. Engineers typically use it with the Border Gateway Protocol and the VXLAN encapsulation protocol. The latter creates an overlay network on an existing Layer 3 infrastructure.

Offering a common set of protocols lets Juniper target its campus switches at data center customers, Casemore said. “That’s a less resistant path than trying to displace other vendors in both the data center and the campus.”

Juniper released the EX4650 four months after releasing two multigigabit campus switches, the EX2300 and EX4300. Juniper also released in February a cloud-based dashboard, called Sky Enterprise, for provisioning and configuring Juniper’s campus switches and firewalls.

Juniper rivals Arista and Cisco are also focused on the campus market. In May, Arista extended its data center switching portfolio to the campus LAN with the introduction of the 7300X3 and 7050X3 spline switches. Cisco, on the other hand, has been building out a software-controlled infrastructure for the campus network, centered around a management console called the Digital Network Architecture (DNA) Center.

SD-WAN upgrade

Along with introducing the EX4650, Juniper unveiled this week improvements within its software-defined WAN for the campus. Companies can use Juniper’s Contrail Service Orchestration technology to prioritize specific application traffic traveling through the SD-WAN. The capability supports more than 3,700 applications, including Microsoft’s Outlook, SharePoint and Skype for Business, Juniper said.

Juniper runs its SD-WAN as a feature within the company’s NFX Network Services Platform, which also includes the Contrail orchestration software and Juniper’s SRX Series Services Gateways. The latter contains the vSRX virtual firewall, IP VPN, content filtering and threat management.

Juniper has added to the NFX platform support for active-active clustering, which is the ability to spread a workload across NFX hardware. NFX runs its software on a Linux server.

The clustering feature will improve the reliability of the LTE, broadband and MPLS connections typically attached to an SD-WAN, Juniper said.

Never used , all 4 for £32 posted , Paypal only.

I bought these a few years ago direct from Trekstor in Germany for about £54 with the plans of using them for write protected Linux Live sticks that can’t get altered but never got around to using them.

They have that budget Chinese build feel and they are not particularly fast but obviously that’s not their purpose as you…
