| Part Number | DCS-7700R4-38PE-F |
| Condition | New |
| Product Series | Arista 5000 Series |
| Architecture | Distributed Disaggregated Chassis (DDC) — decoupled spine, fabric, and line-card nodes unified under single EOS control plane |
| AI Networking Technology | Etherlink — Arista's AI-optimized Ethernet transport for GPU collective communications |
| Target Interface Speed | 800GbE per port (400GbE and 200GbE backward compatible) |
| Fabric Connectivity | High-speed internal fabric interconnect between DDC nodes via 800G or multi-lane optical links |
| Forwarding Architecture | Non-blocking Clos fabric with per-destination ECMP and adaptive load balancing across fabric nodes |
| Buffer Architecture | Deep Virtual Output Queue (VOQ) buffering per priority class to eliminate head-of-line blocking in all-to-all AI workloads |
| RDMA Support | RoCEv2 (RDMA over Converged Ethernet v2) with hardware-accelerated lossless transport |
| Congestion Management | DCQCN (Data Center Quantized Congestion Notification), ECN marking, PFC (Priority Flow Control) per-priority |
| Routing Protocols | BGP (with BGP-LU, BGP EVPN), IS-IS, OSPFv2/v3, BFD for fast failure detection |
| Overlay Support | VXLAN, EVPN multi-homing, SR-MPLS, segment routing IPv6 (SRv6) |
| Management Interfaces | eAPI (REST), NETCONF/YANG, OpenConfig, gRPC/gNMI, SNMP v2c/v3, Syslog |
| Telemetry | Nanosecond-granularity streaming telemetry via gNMI/gNOI; CloudVision integration for fabric-wide AI flow analytics |
| Operating System | Arista EOS (Extensible Operating System) — single unified OS image across all DDC nodes |
| Redundancy | N+1 and N+N supervisor redundancy; hitless failover; non-stop forwarding (NSF); distributed fabric node resilience |
| Power Architecture | Distributed power shelves per node; hot-swappable PSUs; 48V DC and AC input options |
| Cooling | Front-to-rear airflow per node; hot-swappable fan modules; variable speed control via EOS thermal management |
| Form Factor | Distributed 1U/2U nodes; rack-composable fabric — no centralized chassis midplane |
| Standards Compliance | IEEE 802.3 (Ethernet), IEEE 802.1Q, IEEE 802.1Qbb (PFC), IEEE 802.1Qaz (ETS), RoCEv2 (IETF RFC 5040) |
| Launch Date | Q4 2025 |
