Arista 7170 Series Multi-function Programmable Platforms

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 highly flexible and 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 shared packet buffer pool of 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 with 32 QSFP100 ports is based on the same architecture as 7170-64C providing the full throughput and performance in a dense 1RU chassis supporting up to 32x 40/100GbE, 64x 50GbE or 128x 10/25GbE interfaces. The 7170-32CD delivers the same port configuration as the 7170-32C with dual pipelines, connecting the 32 ports with the same capabilities as the 7170-64C

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.
