7020R Series - Arista Networks


High Performance and Deep Buffer One and Ten Gigabit Ethernet Switch

Datacenters demand high-performance networking solutions. The Arista 7020R Series expands the portfolio of Arista fixed and modular deep buffer systems with high performance and power-efficient solutions.

Designed for IP storage, Content Delivery, and leaf and spine networks, the Arista 7020R Series fixed-configuration switches combine dynamic and deep buffering for lossless forwarding with high density, large table sizes, and comprehensive L2 and L3 features. Ultra-deep buffers and VOQ provide lossless performance in demanding environments where congestion and large flows are present such as in Big Data environments or Media and Entertainment. The non-blocking architecture improves the performance of bandwidth-intensive applications found in High-Performance Storage or streaming video.

When used in conjunction with the Arista 7000 series of fixed and modular switches it allows networks to scale out in a high-performance two-tier network that provides predictable and consistent application performance.


7020R Series - Arista Networks


Offering a choice of models the 7020TR Series have 48 RJ45 ports for 100/1000Mb Ethernet and 6 SFP+ ports for both 1GbE or 10GbE uplink connections. The 7020SR Series have 24 or 32 SFP+ ports for both 1G or 10G connections and 2 ports of 100G.
