Description

The Arista 7500R2AK-36CQ is a 36-port 100GbE QSFP100 line card for the Arista 7500R modular chassis. It is built for large-scale data centre spine roles, internet peering and edge routing, layer 3 ECMP, MLAG and VXLAN overlay designs, and deep-buffer workloads that need very large route tables.

Each 100G port runs at wire speed, with 3.34 Bpps of forwarding and 24 GB of port buffer. Every port supports quad 10GbE or 25GbE breakout, dual 50GbE, single 40GbE or 100GbE, and speed changes are made per port without affecting the others, giving up to 144 x 25GbE from a single card. The AK variant adds AlgoMatch flexible pattern matching for access control, policy-based forwarding and telemetry, and FlexRoute scales to about 2M IPv4 and 1.4M IPv6 unicast LPM routes. A distributed virtual output queue architecture provides a lossless fabric without head-of-line blocking.

The card installs in the DCS-7504N, 7508N, 7512N and 7516N chassis, as well as the legacy DCS-7504 and DCS-7508, and interoperates with 7500E Series line cards. It runs Arista EOS from the host chassis and draws typical power of 830 W (894 W maximum) from the chassis power supplies.

FAQs

Q: Which chassis does this line card fit?
A: It is supported in the Arista DCS-7504N, DCS-7508N, DCS-7512N and DCS-7516N chassis, and in the legacy DCS-7504 and DCS-7508. It works alongside 7500E Series line cards.

Q: What power does it need?
A: It draws a typical 830 W and a maximum of 894 W from the chassis, measured at 25 C ambient with 50% load on all ports. The chassis is powered by PWR-3KT-AC-RED, PWR-3KT-HV-RED or PWR-3K-DC-RED supplies.

Q: Which optics and speeds do the ports support?
A: The 100G QSFP ports accept 100GBASE-SR4, XSR4, SWDM4, SRBD, LR, LR4, LRL4, CWDM4, XCWDM4, PSM4, ERL4, AOC and CR4. They also accept 40G QSFP+ optics and cables, plus 25G breakout using 25GBASE-CR QSFP to SFP25.

Q: How does the 7500R2AK differ from other 7500R line cards?
A: This AK variant adds AlgoMatch flexible pattern matching and extends FlexRoute to about 2M IPv4 routes. It provides 36 x 100GbE QSFP100 ports with 24 GB of port buffer.

Q: Does the line card need a separate licence?
A: It runs Arista EOS in the host 7500R chassis. No separate licence for the line card itself is specified.
