Data Center Ethernet Switch Market Surpasses $20 Billion and 100 Million

Ports, Reports Crehan Research

400GbE and 800GbE Grow to One-Third of Total Annual Revenue

SAN FRANCISCO, March 24, 2025 — A late-year acceleration in branded switch

sales helped propel the total data center Ethernet switch market to beyond $20 billion

and 100 million port shipments in 2024, according to the latest report from Crehan

Research. The increase resulted in a record-high year for revenue and shipments,

with annual growth in both branded and ODM-direct data center Ethernet switching.

Key drivers were 400 gigabit Ethernet (GbE) and 800GbE, with these two

technologies increasing 50% year-on-year to comprise a third of total annual market

revenues (see accompanying chart).

“The

data

center

Ethernet

switch

market growth was

the result of a number

of

factors,"

said

Seamus

Crehan,

president of Crehan

Research. "There was

a return to buying new

switches by customers

who had overbought

as a result of the market’s earlier supply constraints. And in addition to that, we had

cloud service providers buying switches to network generative AI clusters.”

Crehan’s report notes that while the adoption of 400GbE data center switching has

been broad-based across applications and customer segments, the strong adoption of

800GbE has so far been primarily driven by generative AI. "The strong early

800GbE adoption is in line with our expectation that this technology will likely see

the fastest ever data center Ethernet switch speed ramp," Crehan said.
