@DellEMC has added #SDWAN for the branch office to its open networking portfolio, while introducing faster switches that are most likely to appeal to cloud providers, carriers and large financial institutions. Dell EMC unveiled this week several hardware options for companies willing to use SD-WAN software from @SilverPeak Inc., @VeloCloud Networks Inc. or @VersaNetworks. The hardware selection includes a #Precision 5000 Series PC or #PowerEdge server. The choice of hardware within the Dell #opennetworking portfolio will depend on the amount of horsepower a company needs. Dell EMC support is responsible for fixing problems with the hardware or software, even if one of the SD-WAN vendors is called in for assistance, said Jeff Baher, the executive director of networking at Dell EMC. Dell EMC's strategy of one-vendor support for a multivendor product is different from most companies, which sell the SD-WAN software alone or running on their appliance. "It is definitely a novel approach," Rohit Mehra, an analyst at IDC, said of the Dell open networking strategy. "This allows them to make a play in this hot and exploding market." Indeed, revenues from SD-WAN infrastructure and services will rise nearly 70% a year to $8.05 billion in 2021, according to IDC. Companies moving business applications to public clouds and subscribing to software as a service are driving the booming SD-WAN market. The technology lowers the cost for companies connecting branch offices to the internet to reach cloud and SaaS applications. Dell EMC boosts switching performance Dell EMC's latest open switches include the 10/100 Gigabit Ethernet S4200-ON and the 25/100 GbE S5048 and S5148. Dell has switches at these speeds in its portfolio, but achieves better performance in the latest hardware through the use of Broadcom's most recent application-specific integrated circuit (ASIC), dubbed Jericho. The Broadcom ASIC provides Dell with the technology to significantly increase the buffer in the S4200-ON -- ON stands for open networking. Also, the chipset makes it possible to support a more extensive routing table than other products in the Dell open networking portfolio. Therefore, the S4200-ON is better suited for handling east-west traffic within cloud computing and virtualized environments found in the mega-data centers of carriers, cloud providers and banks. The switch is also suitable for routing traffic between data centers, according to Dell.
