Technical content

Significant growth in the scale, performance and complexity of data centre networks has created new challenges for designers. Network functions that traditionally required dedicated appliances are no longer able to keep pace with the required data rates in an economical fashion. The Arista 7170B Series are second-generation purpose built, high density, fixed configuration 100GbE systems with up to 6.4 Tbps performance in a compact, low power form factor. Built around a fully P4 programmable data plane, the packet processor architecture allows for complete de finition of packet parsing, lookups, tra ffic scheduling, packet modification and tra ffic monitoring. The 7170 harnesses this flexibility to deploy complex functions, usually only available in CPU based appliances, at wire speed directly in the network layer providing orders of magnitude performance improvements and power/space reduction. Arista provides multiple user selectable pipeline pro files that focus on use cases including high scale tunneling, address translation and server load balancing combined with scalable L2 and L3 resources and rich EOS features. The unique flexibility means new pipeline features and applications can be developed and deployed without replacing the underlying hardware. The Arista 7170B-64C o ffers 64 QSFP ports for dense 40/100 GbE deployments and can support flexible combinations of 10, 25, 40, 50 and 100 GbE. 7170B Series Programmable Data Center Switches Data Sheet Product Highlights Performance

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 its powerful x86 CPU subsystem.

7170B Series | Model Overview Model Overview The 7170B-64C is a 2RU system with 64 100G QSFP ports o ffering wire speed performance with an overall throughput up to 6.4 Tbps. Each QSFP port is capable of a choice of 40/100GbE, with support for up to 128 10/25G ports when using breakouts. Two integrated SFP+ ports provide support for additional lower speed 1/10G interfaces. High Availability and Flexibility The Arista 7170 Series were designed for flexible deployment and continuous operations with system wide monitoring of both hardware and software components, simple serviceability and provisioning to prevent single points of failure. Key features include:

  • AC and DC power supply options
  • Front to Rear cooling with dynamic temperature control.
  • Redundant, color coded, field serviceable power and cooling subsystems:
  • 1+1 hot-swappable platinum rated power supplies
  • N+1 hot-swappable fans
  • Live software patching
  • Self healing software with Stateful Fault Repair (SFR) 7170 2RU Rear View Arista 7170B-64C: 64x 100GbE QSFP100 ports, 2 SFP+ ports Programmable Architecture The 7170B series o ffers a protocol independent switch architecture with a highly programmable packet pipeline that allows the addition of new protocols, encapsulation and tunneling features to the packet processor through simple software upgrades without changes to the underlying hardware. With up to 80 programmable stages, the 7170B series provides more than twice as much pipeline capacity as the previous generation 7170, enabling new profiles with more complex functionality and greater scalability. Arista leverages P4 to de fine advanced forwarding pro files for the 7170 packet pipeline to deliver custom behavior, change lookups performed on the packets or rapidly develop and test new functionality. This flexibility provided by multiple forwarding profiles written in P4 and compiled into Arista EOS, addresses multiple real world requirements for scale, advanced telemetry, security and encapsulation and can be further customized to speci fic customer use-cases. The Enhanced feature license enables use of specialist profiles.

7170B Series | Platform Overview Match-Action Units The 7170 series packet processor pipeline consists of identical blocks of pipeline stages or Match-Action Units. The pipeline program, know as a profile, defines the functions implemented by each Match-Action Unit, matching speci fic information extracted from packet headers and performing lookups in the resource tables which then de fine modifications and forwarding decisions. This architecture results in a configurable data plane with very high throughput, broad range of packet processing functionality and application visibility. Flexible and Scalable Resources Network scalability is directly impacted by a switch’s forwarding tables. Programmable pro files enable the 7170 Series to provide flexibility on how memory resources are allocated among the di fferent tables and features. The architecture allows for flexible and programmable allocation of available resources to achieve maximum e fficiency for a given customer application. The unique level of pipeline programmability enables deployment of the 7170 Series in traditional roles with standard scale requirements as well as a wide range of use cases with unique resource requirements. Intelligent Packet Buffers The Arista 7170B Series switches o ffer up to 64 MB of uni fied packet buffer that is shared dynamically across all ports. The packet bu ffer can be allocated programmatically across multiple classes of applications to optimize performance for custom applications along with standard data center applications designed to avoid congestion from micro-bursts or fan-in packets. Unlike architectures with small per-port packet memory, or small shared memory pools the 7170 Series use a scheme to allocate memory intelligently based on a combination of traffic class, queue depth and quality of service policy ensuring fair allocation to all ports. Application Profiles The 7170 series with Arista EOS support a rich set of both data plane and control plane features and capabilities with a programmable SDK that address the deployment in either a leaf or spine role in two-tier networks. In addition, configurable application specific profiles provide a targeted set of data plane and control plane features with the feature scale tailored to address specific deployment scenarios. Some examples of solutions the 7170 Series can enable:

  • Bare-metal Integration with Network Overlays and Virtualization: Enables large scale integration of bare metal compute into virtualized overlays, offloading network functions such as traffic segmentation or tunnel encapsulation from bare metal servers freeing up compute resources and accelerating applications.
  • Large Scale Network Address Translation: Provides highly scalable static and dynamic network address and port translation (NAT) at line rate with synchronization for gateway redundancy.
  • IPv4 to v6 transition with MAP-T: Implements line-rate, high scale, stateless translation between IPv4 and IPv6 enabling service providers to remove IPv4 from core networks without the need for complex CGNAT deployments.
  • Stateless Load Balancing: Delivers high bandwidth, low latency load balancing for distributed applications including cloud, web and containerized workloads.
  • Broadcast Media Workflows: Provides in-network support for broadcast specific requirements including clean switching, stream reconstruction and advanced address translation.
