Description

The Arista 7500R2A-36CQ is a line card for the 7500R Series modular data centre switch routers. It is built for large-scale spine and leaf layer 2 and layer 3 designs, VXLAN overlay networks, internet peering and data centre interconnect, where deep buffers and large routing tables matter.

The card provides 36 wire-speed 100GbE QSFP100 ports with 16 GB of packet buffer and 3.34 Bpps of forwarding performance. Each port can run in 10GbE, 25GbE, 40GbE, 50GbE or 100GbE modes, giving up to 144 x 10GbE or 25GbE, 72 x 50GbE or 36 x 40GbE. Arista AlgoMatch delivers flexible pattern matching for access control, policy-based forwarding and telemetry, with IPv4 and IPv6 ACLs at the same scale. This variant is the 16GB buffer AlgoMatch card, not the 2M-route 7500R2AK. Typical power draw is 830W, with a maximum of 894W.

It fits the Arista 7516N, 7512N, 7508N, 7504N, 7504 and 7508 chassis, and requires 7500R fabric modules and a Sup2 supervisor. It interoperates with 7500E series line cards and accepts industry-standard QSFP100 and QSFP+ optics and breakout cables.

Enquire with XS Network Tech for new or used pricing and availability.

Features

- Arista AlgoMatch for flexible pattern matching in access control, policy-based forwarding and network telemetry
- IPv4 and IPv6 access control at the same scale
- Per-port speed selection across quad 10GbE/25GbE, dual 50GbE, single 40GbE and 100GbE modes, independent of other ports
- Distributed virtual output queue architecture with a lossless fabric that avoids head-of-line blocking
- Non-blocking full-mesh connectivity to all fabric modules
- Hot-swappable in the 7500R chassis with redundant supervisors, power, fabric and cooling
- Runs the Arista EOS single binary image with LANZ, VXLAN, sFlow, IEEE 1588 PTP and ZTP support

FAQs

Q: Which chassis does this line card fit?
A: It fits the Arista 7516N, 7512N, 7508N, 7504N, 7504 and 7508 chassis. The chassis needs 7500R fabric modules and a Sup2 supervisor.

Q: What port speeds does it support?
A: Each of the 36 QSFP100 ports runs at 100GbE, 50GbE, 40GbE, 25GbE or 10GbE. Speed can be set per port, independent of the other ports.

Q: Does it need a software licence?
A: It runs Arista EOS. Optional chassis software licences are sold separately, such as Enhanced routing (OSPF, BGP, ISIS, PIM) and Virtualization (VM Tracer and VXLAN), licensed per number of slots.

Q: What power does it draw?
A: Typical draw is 830W and maximum is 894W, measured at 25 C ambient with 50% load on all ports. It is powered from the chassis, which uses N+N redundant 3000W AC or DC power supplies.

Q: How does it differ from the 7500R2AK variant?
A: This card is the 16GB buffer AlgoMatch model. It is not the 2M-route 7500R2AK variant, so check your routing table scale requirements when choosing between them.
