Arista DCS-7500R2AK-36CQ-LC | 7500R2 36-Port 100G Line Card, AlgoMatch, 2M Routes

Q: What chassis models support the DCS-7500R2AK-36CQ-LC line card?
A: This line card is compatible with all Arista 7500R Series modular chassis including the 7504R (4-slot), 7508R (8-slot), 7512R (12-slot), and 7516R (16-slot) models. It also interoperates with 7500E Series chassis for investment protection.

Q: What is AlgoMatch technology and how does it benefit network operations?
A: AlgoMatch is Arista's unique innovation combining software and hardware to enable flexible and scalable access control, policy-based forwarding, and network telemetry. It provides efficient pattern matching across more fields while maintaining full capacity, delivering higher scale and performance than traditional solutions with lower power consumption.

Q: Can this line card support multiple Ethernet speeds simultaneously?
A: Yes, the DCS-7500R2AK-36CQ-LC supports flexible multi-rate configurations including 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE. Speed changes and breakout modes can be configured independently per port, providing comprehensive investment protection for both existing and future network designs.

Q: What makes the 2M route capacity significant for data center deployments?
A: The extended FlexRoute capacity supporting up to 2 million IPv4 and IPv6 routes makes this line card ideal for large-scale data center spine applications, internet edge deployments, and cloud environments requiring full internet routing tables or massive multi-tenant routing scale with advanced MPLS, EVPN, and VXLAN services.

Q: How does the Virtual Output Queue architecture improve performance?
A: The deep buffer VoQ architecture with 16GB of packet memory eliminates head-of-line blocking and virtually eliminates packet drops even in congested scenarios. It provides fairness across all ports, ensures QoS policies are enforced, and delivers approximately 50ms of traffic buffer per ingress port for handling mixed workloads including real-time, multicast, and storage traffic.
