7368X4 Series | Platform Overview

High Availability

The Arista 7368X4 are optimized for cloud networking operations and maintenance with system wide monitoring of all hardware and

software components, simple serviceability and provisioning for ease of maintenance and system expansion. The 7368X4 supports

simple replacement of all components including the supervisor, switch card and interface modules, power supplies and fans. The 7368X

Series o ers power and cooling high availability and N+1 redundancy. The switch card, power supplies and fans are rear removable

ensuring no disruption to either the interface modules or network cabling.

The Arista 7368X4 series switches were designed for high availability from both a software and hardware perspective. Key high

availability features include:

• Hot-swap of all interface modules

• Four N+N hot-swappable power supplies

• Five high performance N+1 hot-swap fans

• Color coded PSU’s and fans

• Live software patching for zero downtime maintenance

• Self healing software with Stateful Fault Repair (SFR)

• Smart System Upgrade (SSU) to simplify software upgrades *

• Up to 128 100G/200G/400G ports per link aggregation group

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

• 128-way ECMP routing for load balancing and redundancy

Maximum Flexibility for Scale Out Network Designs

Scale out network designs enable solutions to start small and evolve over time. A simple two-way design can grow as far as 128-way

without signi cant changes to the architecture. The Arista 7368X4 provide a consistent architecture with the 7060X4 Series and a

choice of either 100G QSFP, 400G OSFP and QSFP-DD interfaces, providing investment protection and future proof migration from 100G

to 400G optimized for large scale cloud networks. They include several enhancements for hyper-scale cloud data center designs:

• Wide choice of optics and cables for multi-speed exibility from 10G to 25G to 100G to 200G and 400G

• 128-way ECMP and 64-way MLAG for scalable designs and to balance tra c evenly across large scale multi-tier designs

• Enhanced ECMP Hashing and Load Balancing consider real-time loads and dynamically assign new and existing ows to the best link

to improve performance

• Support for standards based IEEE 100GbE for simple and cost e ective migration from to 100G and 400G

• Advanced Multi-pathing improves congestion management by rebalancing ows in large scale cloud environments under load

• Hitless speed changes to eliminate down-time when implementing changes

• LANZ, sFlow and multi-port mirroring to detect micro-burst congestion and provide network wide visibility and monitoring

• Flow aware detector to identify large ows and selectively allow marking and queue assignment to optimize tra c forwarding

AI Analyzer *

Traditional software-based tra c counters do not lend themselves to examine AI/ML tra c patterns, which exhibit unique ramp up

behavior in very short intervals of time. The AI Analyzer is a hardware capability that enables the collection of ECMP member utilization

data, aggregated over extremely short periods of time. This allows the Arista 7368X4 series to e ectively analyze the tra c patterns,

with a time interval as granular as 100 microseconds. The results of such an analysis can then be applied to ne tune dynamic load

balancing workloads uniformly across the ECMP member links, which is a key requirement for AI/ML applications.

CloudVision

CloudVision is a network-wide approach for workload orchestration and work ow automation as a turnkey solution for Cloud

Networking. CloudVision extends the EOS publish subscribe architectural approach across the network for state, topology, monitoring

and visibility. This enables enterprises to move to cloud-class automation without needing any signi cant internal development.
