Overview

Highly dynamic cloud data center networks continue to evolve with the

introduction of new protocols and server technologies such as containers bringing

with them ever increasing bandwidth demands, accelerating the need for dense 100

Gigabit Ethernet switching in data center networks.

The Arista 7170 Series are purpose built fixed configuration 100GbE systems built for

the highest performance environments, and to meet the needs of the largest scale

data centers. They offer scalable L2 and L3 resources and high density with a highly

programmable and customizable switch architecture combined with advanced

features for software defined cloud networking and emerging requirements. With a

uniquely flexible programmable architecture, the 7170 series allow reconfiguration

of packet parsing, lookups, traffic scheduling, packet modification and traffic

monitoring without re-engineering the switch architecture.

The Arista 7170-64C is a programmable data center switch with a packet buffer pool

of up to 22MB that is shared across all ports. With 64 QSFP100 ports the 7170-64C is

a dense 40/100GbE system that can support a flexible combination of up to 64x

40/100GbE, 128x 50GbE or 256x 10/25GbE of wire speed performance in a 2RU

system.

The Arista 7170-32C/CD provide 32 QSFP100 ports based on the same architecture

as 7170-64C offering full throughput and performance in a dense 1RU chassis

supporting up to 32x 40/100GbE, 64x 50GbE or 128x 10/25GbE interfaces. The

7170-32C additionally provides double the system pipeline capacity to

accommodate more advanced features and higher scalability.

Arista EOS

The Arista 7170 series runs the same Arista EOS software as all Arista products,

simplifying network administration. Arista EOS is a modular switch operating system

with a unique state sharing architecture that cleanly separates switch state from

protocol processing and application logic. Built on top of a standard Linux kernel, all

EOS processes run in their own protected memory space and exchange state

through an in-memory database. This multi-process state sharing architecture

provides the foundation for in-service-software updates and self-healing resiliency.

With Arista EOS, advanced monitoring and automation capabilities such as Zero

Touch Provisioning, VMTracer and Linux based tools can be run natively on the

switch with the powerful x86 CPU subsystem.
