Feature rich next-generation 400GbE and 100GbE Modular solutions for Enterprise, Hyperscale Cloud and I/O intensive environments.

The Arista 7358X4 Series deliver high density 100G and 400G optimized for Enterprise, Hyperscale Cloud, Artificial Intelligence and Machine Learning environments employing high network radix. The 7358X4 is a modular system built on a single high capacity 12.8Tbps packet processor for data intensive and high performance workloads requiring consistent low latency, with a flexible choice of industry standard interfaces in power efficient and compact systems.

The adoption of high performance servers using virtualization and containers with increasingly higher network bandwidth is accelerating the need for higher density switching in both the leaf and spine tiers of modern networks.

The Arista 7358X4 Series high performance flexible data center switches provide 25G, 100G and 400G Ethernet and are loaded with features for wire speed L2 and L3, including integrated advanced traffic awareness, congestion handling and instrumentation that improve network resilience, visibility and congestion management in large scale multi-tier networks, and offer multiple generations of consistency for software driven cloud networking.
