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.

For Sale – Synology DS116 + WD 1TB HDD installed

I have my old Synology DS116 NAS with a WD 1TB HDD fitted for sale. Comes with ethernet cable and PSU.

I was just about to run out of disc space so I’ve moved on to a new DS118 with 4TB WD HDD.

I bought this secondhand off another forum about 9 months ago to dip my toe into streaming and it’s worked flawlessly for me. I have had it in Quiet Mode and it’s silent in operation. It’s got a few marks here and there but nothing major.

I was a complete novice when it came to all this streaming malarkey and I learnt everything I needed to know from the Synology.Com website and various tutorials on YouTube.

No original packaging but it will be well packed for postage. The HDD has been cleared of all my data so you wont have to endure my crap music collection.

Collection welcome.

I’ve also got this up on Ebay but offering it here at a knockdown price.

Cheers

Juniper preps 400 GbE across PTX, MX and QFX hardware

Juniper plans to add 400 Gigabit Ethernet across its PTX and MX routers and QFX switches as internet companies and cloud providers gear up for the higher throughput needed to meet global demand from subscribers.

Juniper said this week it would roll out higher speed ports in the three product series over the next 12 months. The schedule is in line with analysts predictions that vendors would start shipping 400 GbE devices this year.

Juniper will market the devices for several uses, including a data center backbone, internet peering, data center interconnect, a metro core, telecommunication services and a hyperscale data center IP fabric.

The announcement follows by a month Juniper’s release of the 400 GbE-capable Penta, a 16 nanometer (nm) packet-forwarding chipset that consumes considerably less energy than Juniper’s other silicon. Juniper designed the Penta for carriers rearchitecting their data centers to deliver 5G services.

Penta is destined for some of the new hardware, which will help Juniper meet carrier demand for more speed, said Eric Hanselman, an analyst at New York-based 451 Research.

“Juniper has such a strong base with service providers and network operators and they’re already seeing strong pressure for higher capacity,” Hanselman said. “Getting the Penta silicon out into the field on new platforms could help to move Juniper forward [in the market].”

The upcoming hardware will also use a next-generation ExpressPlus chipset and Q5 application-specific integrated circuit. The Juniper silicon will provide better telemetry and support for VXLAN and EVPN, the company said.

Cloud developers use EVPN, VXLAN and the Border Gateway Protocol to set up a multi-tenancy network architecture that supports multiple customers. The design isolates customers so data and malware can’t travel between them.

For the IP transport layer, Juniper plans to introduce in the second half of the year the 3-RU PTX10003 Packet Transport Router for the backbone, internet peering and data center interconnect applications. The hardware supports 100 and 400 GbE and plugs into an existing multirate QSFP-DD fiber connector system for a more straightforward speed upgrade. The Juniper system provides MACSec support for 160 100 GbE interfaces and FlexE support for 32 400 GbE interfaces. The upcoming ExpressPlus silicon powers the device.

Also, in the second half of the year, Juniper plans to release for the data center the QFX10003 switch. The system packs 32 400 GbE interfaces in 3-RU hardware that can scale up to 160 100 GbE. The next-generation Q5 chip will power the system.

In the first half of next year, Juniper expects to release the QFX5220 switch, which will offer up to 32 400 GbE interfaces in a 1-RU system. The Q5-powered hardware also supports a mix of 50, 100 and 400 GbE for server and inter-fabric connectivity.

Finally, for wide-area network services, Juniper plans to release Penta-powered 400 GbE MPC10E line cards for the MX960, MX480 and MX240. The vendor plans to release the products on the first of next year.

Juniper is likely to face stiff competition in the 400 GbE market from Cisco and Arista. Initially, prices for the high-speed interfaces will be too high for many companies. However, Hanselman expects that to change over time.

“The biggest challenge with 400 GbE is getting interface prices to a point where they can open up new possibilities,” he said. “[But] healthy competition is bound to make this happen.”

Indeed, in 2017, competition for current hardware drove Ethernet bandwidth costs down to a six-year low, according to analyst firm Crehan Research Inc., based in San Francisco. By 2022, 400 GbE will account for the majority of Ethernet bandwidth from switches, Crehan predicts.
