Description

The Arista DCS-7512R3-FM is a high-performance fabric module designed specifically for the 7500R3 Series 12-slot modular chassis. This integrated fan fabric module is required for fabric slots 1-6 and delivers up to 3.2 Tbps of full-duplex fabric bandwidth per line card slot. With six fabric modules installed, the system achieves 19.2 Tbps full-duplex bandwidth, supporting non-blocking architecture for data center spine and cloud network deployments with hot-swap capability and N+1 redundancy.

Features

100% efficient cell-based fabric architecture eliminates fabric congestion
- Virtual Output Queuing (VoQ) per port eliminates head-of-line blocking
- Active-active operation across all six fabric modules for full bandwidth utilization
- N+1 redundancy ensures continuous operation with any single fabric module failure
- Hot-swappable design enables maintenance without system downtime
- Integrated fan assembly with variable speed control for optimized cooling
- Non-blocking full mesh connectivity between all line card modules
- Front-to-rear airflow optimized for hot-aisle/cold-aisle data center design
- Passive midplane connectivity for high reliability
- Supports mixed line card configurations with consistent performance
- Compatible with all 7500R3 Series line cards including 400G, 100G, and 25G modules
- Zero packet loss fabric switching with deterministic performance

FAQs

Q: How many fabric modules are required for the 7512R3 chassis?
A: The 7512R3 chassis has six fabric slots (1-6) and requires all six DCS-7512R3-FM modules for full system bandwidth and redundancy. The system operates with N+1 redundancy, meaning five modules provide full performance while the sixth provides redundancy.

Q: Can I hot-swap fabric modules without disrupting traffic?
A: Yes, the DCS-7512R3-FM modules are fully hot-swappable with zero performance degradation during replacement. The active-active architecture with N+1 redundancy ensures continuous operation when servicing individual fabric modules.

Q: Is the DCS-7512R3-FM compatible with older 7500R or 7500R2 chassis?
A: No, the DCS-7512R3-FM is specifically designed for the 7500R3 Series 7512N chassis. Each chassis generation (7500R, 7500R2, 7500R3) requires its own fabric module variant due to different fabric architectures and bandwidth requirements.

Q: What is the fabric bandwidth per line card slot?
A: Each DCS-7512R3-FM fabric module provides 3.2 Tbps full-duplex bandwidth per line card slot. With all six fabric modules installed, each of the twelve line card slots has access to 19.2 Tbps full-duplex fabric capacity, enabling non-blocking wire-speed forwarding.

Q: Does the fabric module include cooling fans?
A: Yes, the DCS-7512R3-FM features an integrated fan assembly that provides rear-mounted cooling with front-to-rear airflow optimized for data center deployments. The cooling system supports N+1 redundancy and dynamic temperature control.
