Open Networking/SDN Reference Models + Bare Metal Switches increase market share in Data Centers

Introduction:

Open networking, which leverages open source software and open hardware designs and allows anyone to innovate, is set to change networking, just as open source changed the server and OS marketplace,” said Cliff Grossner, Ph.D., research director for data center, cloud and Software Defined Networking (SDN) at IHS.  

“This move to open networking is heightening the importance of bare metal switches, as evidenced by all the vendor announcements at Interop in April. Dell is expanding its open networking portfolio with three new branded bare metal switches providing options from 1GE to 100GE Ethernet. And Citrix entered the SD-WAN market with Cloudbridge Virtual WAN Edition, which allows enterprises to create a virtualized WAN,” Grossner said.  

Open Networking/SDN Reference Models:

 Mr. Grossner and this author are collaborating on a report/article defining Open Networking Reference Architectures, Business Models, and Vendors Market Share.   We’ve identified the following reference architectures:

a]  Pure SDN/OpenFlow: Open Network Foundation (ONS)
b]  Network Virtualization/Overlay:  VMware, Nuage Networks, Juniper Contrail, Miokura
c]  Evolution/augmentation: new, emerging protocols AND APIs added to existing network equipment vendor gear. Examples include: VxLAN, NVGRE, Geneve for tunneling and RESTful API’s for programmability/Northbound API from SDN Controller to Application Programs.
d]  Bare metal switch with Open Network OS (e.g. Cumulus or BigSwitch Networks) & Open Source software.  This category also includes the Open Compute Project where Facebook (and others) have contributed design details/schematics for Open Source hardware anyone can build.  This is the most flexible model and easiest to change.
e]  Proprietary model:  calling any new auto provisioning/(re) configuration system or routing/path selection algorithm SDN or Open Networking.  AT&T has done as I noted in many previous articles,  e.g. AT&T’s “SDN-WAN” as the Network to Access & Deliver Cloud Services

Bare metal switches, an integral part of open networking, accounted for 12% of data center Ethernet ports shipped worldwide in the first quarter of 2015 (1Q15), according to the IHS – Infonetics Data Center Network Equipment report. Globally, bare metal switch revenue grew 11% year-over-year in 1Q15.
IHS-Infonetics projects solid growth for Bare Metal switches over the next five years (till 2019) as per this chart:

 

DATA CENTER MARKET HIGHLIGHTS:

  • The global data center network equipment market-including data center Ethernet switches, application delivery controllers (ADCs) and WAN optimization appliances (WOAs)-declined 14% sequentially in 1Q15, to $2.6 billion.
  • The data center Ethernet switch segment continues to grow on a year-over-year basis (+4% in 1Q15 from 1Q14); positive forces include large enterprises and the public sector.
  • F5 took the #1 spot for virtual ADC appliance revenue from Citrix in 1Q15.

DATA CENTER REPORT SYNOPSIS:

In an IHS-Infonetics report released earlier this month (June 3, 2015), Cliff forecast that the in-use software-defined networking (SDN) market (Ethernet switches and controllers) will reach $13 billion in 2019, up from $781 million in 2014, as the availability of branded bare metal switches and use of SDN by enterprises and smaller cloud service providers (CSPs) drive growth.

“The SDN market is still forming, and the top market share slots will change hands frequently, but currently the segment leaders are Dell, HP, VMware and White Box,” said Cliff Grossner, Ph.D., research director for data center, cloud and SDN at IHS.

“SDN will cross the chasm in 2016, with SDN in-use physical Ethernet switches accounting for 10 percent of Ethernet switch market revenue,” Grossner said.
