Arista 7020R 系列

High Performance and Deep Buffer 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 a high performance and power efficient solution.

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 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.
