Performance without Compromise: Deep Buffers, 100GbE and Scalable VXLAN in a 1RU

The Arista 7280E Series extends the Arista 1RU product portfolio, providing a combination of deep buffers and the industry’s first 100GbE Top of Rack switch combined with extensive features such as VXLAN and LANZ. The 7280E are built for storage networks, content delivery networks, and lossless spline/leaf datacenter designs.

Arista 7280E Advantages:

  • Improve performance of bandwidth intensive applications found in High Performance Storage or streaming video
  • Ultra deep buffers and VOQ for lossless performance in demanding environments where congestion and large flows are present — as in Big Data environments or Media and Entertainment
  • Wirespeed VXLAN expanding next generation virtualized datacenters
  • Integrated SSD storage allows for unique extensibility abilities, traffic monitoring and Software Defined Networking applications
  • Hardware assisted Precision Time Protocol (PTP) enables accurate timing solutions across Ethernet based networks without costly investments in deploying separate timing networks


The Arista 7280E Series switches are the industry’s first fixed configuration switches combining 10/40/100GbE and an ultra deep buffer with VOQ architecture into a compact 1RU design. They combine scalable L2 and L3 forwarding and traffic management with advanced features for network monitoring, precision timing, and network virtualization to deliver deterministic network performance for mission critical data centers, cloud computing, enterprise and HPC environments.
