7020R Series | Platform Overview

High Availability

The Arista 7020R switches were designed for continuous operations

with system wide monitoring of both hardware and software

components, simple serviceability and provisioning to prevent single

points of failure. Key high availability features include:

• 1+1 hot-swappable power supplies and four hot-swap fans provide

dynamic temperature control combined with N+1 redundancy

• Color coded PSU’s and fans that deliver platinum level power

e ciency

• Live software patching

• Self healing software with Stateful Fault Repair (SFR)

• Up to 32 ports per link aggregation group (LAG)

• Multi-chassis LAG for active/active L2 multi-pathing

• 128-way ECMP routing for load balancing and redundancy

Interconnected 1G Servers with Arista Leaf-Spine Design

Scaling Data Center Performance

The Arista 7020R series delivers line rate switching at layer 2 and layer 3

to enable dramatically faster and simpler network designs for data

centers that lowers the network capital and operational expenses.

When used in conjunction with the Arista 7000 series of xed and

modular switches it allows networks to scale to over 80,000 1G servers

in a high performance and low-latency two-tier network that provides

predictable and consistent application performance. The exibility of

the L2 and L3 multi-path design options combined with support for

open standards provides maximum exibility, scalability and network

wide virtualization. Arista EOS advanced features provide control and

visibility with single point of management.

Model Overview

The 7020SR-24C2 and 7020SRG-24C2 are 1RU systems with 24 10G

SFP+ ports and 2 100G QSFP ports o ering wire speed performance

with an overall throughput up to 880 Gbps. Each SFP+ port o ers a

choice of 1GbE and 10GbE modes with no restrictions. The 2 QSFP

ports support wire speed 100G and can be broken out for a choice of

10G, 25G or 40G modes allowing easy transitions and maximum

exibility, as a dedicated server leaf, hyper converged infrastructure or

as an edge router with 10G and 100G connections. 7020SRG support

for IPsec increases the roles allowing for site-site VPNs or data-center

interconnect. The 7020SR models include support for Accelerated

sFlow.

The 7020SR-32C2 are 1RU systems with 32 10G SFP+ ports and 2

100G QSFP ports o ering wire speed performance with an overall

throughput up to 1.04Tbps. Each SFP+ port o ers a choice of 1GbE

and 10GbE modes with no restrictions. The 2 QSFP ports support wire

speed 100G and can be broken out for a choice of 10G, 25G or 40G

modes allowing maximum exibility, as a dedicated edge router with

1/10G and 100G connections..

The 7020TR-48 and 7020TRA-48 are 1RU systems with 48 100Mb/

1G RJ45 ports and 6 10G SFP+ ports o ering wire speed performance

with an overall throughput up to 216 Gbps. Each SFP+ port allows for

both 1G and 10G modes, ensuring integration with existing networks.

With a deep bu er and VoQ architecture the 7020TR are optimized for

demanding workloads. The 7020TRA-48 includes support for

AlgoMatch, and both the 7020TR and 7020TRA models support

Accelerated sFlow.
