Description

The Arista 7812R 12-Slot Data Centre Chassis Bundle is a high-density, carrier-grade modular switching platform engineered for large-scale spine and core deployments. This comprehensive bundle includes the 7812 chassis, 18x 3kW D1 AC power supplies for fully redundant power, 6x FM-R3 fabric modules, and a 7816 Supervisor module with an Extended Rack Kit — delivering everything required to deploy a fully operational Arista 7800R3 Series chassis out of the box. Designed for hyperscale and enterprise data centres, the 7812R supports terabit-class forwarding capacity, hardware-based segment routing, and deep buffer capabilities that ensure consistent performance under demanding traffic conditions.

The 7800R3 Series architecture leverages Arista EOS (Extensible Operating System) for a consistent, programmable networking stack with support for advanced routing protocols, VXLAN, EVPN, and robust telemetry via streaming gRPC. The 18-power-supply configuration provides N+N redundancy to meet the strictest uptime requirements, while the FM-R3 fabric modules deliver high-bandwidth, non-blocking fabric interconnects across all line card slots.

FAQs

Q: What is included in the DCS-7812R3-BND-18PS bundle?
A: This bundle includes the Arista 7812 chassis, 18x 3kW D1 AC power supplies, 6x FM-R3 fabric modules, one 7816 Supervisor module, and an Extended Rack Kit — providing a complete, ready-to-deploy chassis solution.

Q: What line cards are compatible with the Arista 7812R chassis?
A: The 7812 chassis is compatible with Arista 7800R3 Series line cards, supporting a range of 100G, 400G, and high-density port options. Contact IP Trading to confirm specific line card compatibility for your deployment.

Q: Why does this bundle include 18 power supplies for a 12-slot chassis?
A: The 18x 3kW AC power supply configuration provides fully redundant N+N power, ensuring the chassis continues to operate without interruption even if multiple PSUs fail — critical for mission-critical data centre environments.

Q: Does the Arista 7812R support VXLAN and EVPN for data centre fabric deployments?
A: Yes. The 7800R3 platform running Arista EOS supports VXLAN, EVPN, BGP, segment routing (SR-MPLS), and advanced telemetry, making it well suited for modern data centre spine and leaf fabric architectures.

Q: Can I purchase the Arista 7812R3 bundle in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian IT hardware specialist and can supply, quote, and support the Arista DCS-7812R3-BND-18PS for enterprise and data centre customers across Australia.

Q: What is the role of the FM-R3 fabric modules included in this bundle?
A: The 6x FM-R3 fabric modules provide the high-bandwidth, non-blocking switching fabric interconnect between line cards within the 7812 chassis, enabling terabit-scale forwarding capacity with consistent low-latency performance.
