ANET Arista Announces First 400g switches

I know a lot of folks have moved on from ANET already, but I still own about half of my original stake and continue to follow them.

Apologies if someone else already posted this and I missed it, but Arista launched a couple 400g platforms this week, which I believe was earlier than expected. It’s been four years since they first launched their 100g switches in 2013/2014.…

Arista Networks (NYSE:ANET) today announced two new platforms supporting 400 Gigabit Ethernet. The new 400G fixed systems deliver the performance that hyperscale cloud networks and datacenters need for the growth of applications such as AI (artificial intelligence), machine learning, and serverless compute.

Key features of the new products include:

-4X increase in bandwidth density compared to existing 100G 1U switches
-Optimized shared buffer to lower application latency for AI and storage workloads
-Elephant Flow Detector for advanced traffic management
-Traffic awareness with Dynamic Load Balancing and Dynamic Group Multipath to improve performance in large cloud and HPC networks
-Increased routing capacity combined with 2X IO increase for hyperscale leaf-spine
-Low power optimized with uncompromised performance at 12.8 Tbps
-Consistent EOS support including cloud-based automation, analytics and availability
-Choice of OSFP and QSFP-DD optics supporting 50G/100G/200G and 400G speeds…

As enterprise cloud computing grows in size and importance, the pressure stays on vendors to deliver switches and routers that can handle faster throughput at the lowest possible cost per bit.

Stepping up to that pressure this week is Arista Networks Inc. , at least on paper. The company today is talking up its two new 400 Gigabit Ethernet switches for cloud networks and data centers. The company said the upcoming switches, part of its Arista 7060X4 series, provide four times the throughput and double the power efficiency of its 100G platforms…

…“We see year-on-year growth in intra-data center demand from 50% to 100% for the large-scale data center operators. The more recent growth is driven by serverless compute, NVMe (non-volatile memory express), storage and AI workloads,” said Martin Hull, area vice president of cloud and platform product management for Arista, in an email to Light Reading.
