About the Arista 7800R4 Spine Switch Series
The Arista DCS-7804R4 is a modular spine switch engineered for the demanding architectures of AI/ML fabric, hyperscale data center core, HPC interconnect, and financial services core routing environments. This non-blocking, distributed forwarding platform features a 4-slot modular chassis architecture with a multi-stage distributed fabric backed by dedicated fabric modules, delivering line-rate performance across 400GbE, 100GbE, and 40GbE port speeds depending on installed line cards. Arista's proven EOS (Extensible Operating System) single-image Linux-based network operating system powers the DCS-7804R4, enabling carrier-grade reliability and operational simplicity across hyperscale deployments.
Network architects and AI infrastructure teams select the Arista 7800R4 series for its robust high-availability foundation: dual redundant supervisor modules with stateful switchover (SSO), N+1 and N+N redundant hot-swappable power supplies, and hot-swappable redundant fan trays with flexible front-to-rear and rear-to-front airflow options ensure continuous operation. The platform supports comprehensive routing protocols including BGP, OSPF, IS-IS, SR-MPLS, SRv6, BGP-EVPN, and VXLAN, while management and automation capabilities span OpenConfig, gNMI, gRPC telemetry, NETCONF/YANG, and seamless Arista CloudVision integration. Advanced features such as in-service software upgrade (ISSU) support, graceful restart, BFD, ECMP load balancing, and PTP/IEEE 1588v2 hardware timestamping support deliver the deterministic performance and operational flexibility demanded by modern infrastructure.
Organizations standardizing on Arista switching infrastructure benefit from consistent feature parity and vendor alignment across their fabric.

Frequently Asked Questions about Arista 7800R4 Spine Switch Series
Does the Arista 7800R4 Spine Switch Series support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
