Arista’s new switches support 800GbE for hyperscalers

Arista has introduced its first 800GbE switches as part of its 7060X5 series for hyperscalers and cloud providers. Arista also introduced five new systems in the 7050X4 series for businesses with high-performance computing systems.

Two of the three new members of the hyperscale-focused 7060X5 family will house 32 ports with 800GbE support. The latest addition to the 7050X4 family for enterprise applications provides high port density and increased flexibility to support 10GbE to 400GbE.

“Both have the same type of telemetry and traffic scheduling capabilities, the same type of memory,” said Zeus Kerravala, an analyst at ZK Research. “It’s for two different audiences because of the speed.”

Hyperscalers and enterprise data centers are moving in the same direction, but at different speeds, said Hardev Singh, Head of Data Center Platforms at Arista Networks. For bandwidth-hungry hyperscalers, the 7060X5 series scales up to 800GbE for data center interconnect or backbone connectivity.

“Eventually they want more bandwidth at the lowest cost,” said Singh.

The 7050X4 series supports enterprises building high-performance computing (HPC) clusters and using next-generation applications based on artificial intelligence and machine learning, Singh said.

“For enterprise customers, what’s important is having flexibility and backwards compatibility with existing infrastructure,” he said.

Brad Casemore, research vice president at IDC, highlights the growing gap between the needs of hyperscale and enterprise data centers with the new switches in both series.

“Hyperscaler continues to push the envelope in terms of bandwidth and density for data center switching,” Casemore said. “Businesses have less need for this cutting-edge bandwidth, but they need more features because their environments are so diverse.”

Arista’s five new 7050X4 series use the Broadcom Trident 4 chipset delivering 8.0 Tbps. Provides 10GbE/25GbE, 50GbE/100GbE and 400GbE links at the fabric layer with a flat topology for east-west traffic.

The switches support the cables and fibers customers already have in their data centers, so they don’t need to change when adopting higher gigabit speeds, Casemore said.

Arista’s three new 7060X5 products use the Broadcom Tomahawk 4 chipset to deliver 25.6 terabits of aggregate bandwidth. Two are 32-port 800GbE switches, one with QSFP-DD ports and one with OSFP ports.

All new switches offer in-band telemetry for latency monitoring, traffic scheduling, high-performance shared buffer memory, and enhanced routing and access control lists. It also offers feature and scale parity with 20% to 40% power savings, SFP and QSPF-based systems for versatile computing connectivity, and Virtual Extensible LAN support.

Arista offers investment protection and better power utilization for both hyperscalers and enterprises, even if their needs differ, Casemore said.

“Hyperscalers will continue to move at this breakneck pace at an ever-increasing rate, and as we build data centers around the world, so will the demand for switches,” Casemore said. “Businesses will be moving at a slower pace, but they will still need to transform their data centers to meet their needs.”
