40Gb Spine Solutions: The New Standard in Data Center Networks

The Arista 7050Q switches (compact 1RU) deliver line rate 40GbE performance, offering the lowest latency 16x 40 Gbps switch in the world. The 7050Q is the ideal switch for:

  • Scaling uplink bandwidth between data center leaf switches
  • Ultra-high density 40GbE switching in a compact fixed form-factor
  • Purpose-built spine aggregation switching (1.28 Tbps switching capacity).

Customers can also choose to deploy the 7050Q with a combination of 10Gbps leaf ports and 40 GbE spine ports within the same chassis based on their port density and scale-out requirements.

10Gigabit Ethernet at Gigabit Pricing

The Arista 7050T switches offer triple speed switching of 100Mbps/1GbE/10GbE and backwards compatibility with installed Ethernet cabling and standard RJ-45 connectors. The 7050T is the ideal switch for:

  • Offering the most cost-effective media interfaces (copper)
  • Leveraging existing cable plants, reducing installation and wiring costs
  • Lower energy costs due to more efficient power and cooling, for greater TCO

For greater uplink capacity requirements, customers can choose the 64 port chassis, with up to four QSFP+ 40GbE interfaces, and a mix of RJ-45 connectors with the lower speed interfaces.
