About the Arista 7550X Series AI-Optimized Core Switch Platform
L2/L3 routing with BGP, OSPF, IS-IS, and static routing — combined with VXLAN and MPLS overlay support — determines this platform's role as a high-capacity fabric spine or core switch for modern data centers. The Arista 7550X Series AI-Optimized Core Switch Platform (part number DCS-7550X-CH) is engineered to deliver exceptional throughput and forwarding performance in demanding enterprise environments. Built on a modular chassis architecture with Broadcom Tomahawk 4 forwarding ASICs, this Arista solution scales to meet the connectivity and processing demands of AI/ML workloads, HPC clusters, and cloud-native infrastructure.
For AI infrastructure teams and network engineers deploying next-generation data center fabrics, the 7550X Series combines up to 25.6 Tbps switching capacity with up to 19.2 Bpps forwarding rate to ensure low-latency, high-throughput packet processing. The platform supports 100GbE and 400GbE port speeds, enabling flexible port density configurations through modular line card slots. Native support for hardware-based QoS with traffic shaping, scheduling, and ECN-based congestion management protects application performance across multi-tenant and AI training environments. Arista EOS (Extensible Operating System) provides programmatic control via gNMI, gRPC, NETCONF, REST API, and OpenConfig, while integration with Arista CloudVision (CVP) enables intent-based management and real-time streaming telemetry. Redundant supervisors, redundant hot-swappable AC/DC power supplies, redundant fan trays, and hitless failover ensure carrier-grade availability and zero-downtime maintenance windows. The DCS-7550X-CH is certified for CE, FCC, and RoHS compliance.

Frequently Asked Questions about Arista 7550X Series AI-Optimized Core Switch Platform
Does the Arista 7550X Series AI-Optimized Core Switch Platform 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.
