Cisco Leads in 100 GE Revenue, Arista Leads in Shipments

REDWOOD CITY, Calif. – September 3, 2019 – According to a recent report by Dell’Oro Group, the trusted source for information about the telecommunications, networks, and data center IT industries, weakness in China suppressed Data Center Switch market growth in 2Q 2019. The report also revealed that Cisco is the new leader in 100 GE revenue, while Arista continues to lead in 100 GE shipments.

“Data Center switch market revenue in China declined for the first time in more than five years, due to a slowdown in spending from both Cloud Service Providers (SPs) as well as enterprises,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “Also, the U.S. government’s actions pertaining to Huawei have created some pause in China market demand. In contrast, data center switch market revenue in North America managed to grow despite a slowdown in spending by major Cloud SPs, Most of the slowdown was driven by reduced server purchases while data center switches performed well. Large enterprises also contributed to the growth in North America as they accelerated their 100 GE adoption and helped Cisco emerge as the new leader in 100 GE revenue in 2Q 2019,” added Boujelbene.

Additional highlights from the Ethernet Switch – Data Center  2Q 2019 Quarterly Report:

  • H3C gained more than 3 points of revenue share Y/Y in China
  • All speeds were down Y/Y in shipments and revenue; except 25, 50, 100 and 400 GE.
