Description

The Arista 7500R2-36CQ is a 36-port 100GbE QSFP100 line card for the Arista 7500 Series modular chassis. It is aimed at large virtualised data centres, cloud networks, internet peering and spine and leaf designs that need high 100G density with deep buffers.

All 36 QSFP100 ports run at wire speed, giving 3.6Tbps per line card, with 7.2Tbps of switching capacity (full duplex) and a forwarding rate of 3.34 Bpps. Each port can run at 10, 25, 40, 50 or 100GbE using optics or breakout cables, up to 144 x 10GbE, 144 x 25GbE, 72 x 50GbE, 36 x 40GbE or 36 x 100GbE per card. The card is built on 7500R2 (Jericho+) packet processors with a 16 GB packet buffer and a virtual output queue architecture that removes head-of-line blocking. This is the base 7500R2 variant, without AlgoMatch or MACsec.

It installs in the DCS-7516N, DCS-7512N, DCS-7508N, DCS-7504N, DCS-7504 and DCS-7508 chassis and can be mixed with other 7500R line cards in the same chassis. It uses QSFP100/QSFP28 optics and cables and runs Arista EOS.

FAQs

Q: Which chassis does this line card install in?
A: It installs in Arista 7500 Series chassis: DCS-7516N, DCS-7512N, DCS-7508N, DCS-7504N, DCS-7504 and DCS-7508. It can be mixed with other 7500R line cards in the same chassis.

Q: Which port speeds can each port run?
A: Each QSFP100 port supports 10, 25, 40, 50 and 100GbE using the appropriate optics or breakout cables. A single card supports up to 144 x 10GbE or 25GbE, 72 x 50GbE, 36 x 40GbE or 36 x 100GbE.

Q: What optics and cables does it use?
A: It uses QSFP100 (QSFP28) optics and cables for 100GbE. 40GbE runs on QSFP+ optics, and 10, 25 and 50GbE are available through breakout cables.

Q: How does it differ from other 7500R2 line cards?
A: This is the base 7500R2 variant with 36 x 100G QSFP100 ports. It does not include AlgoMatch or MACsec, which are found on other 7500R2 line card variants.

Q: Where does this line card get its power?
A: It is powered from the 7500 chassis, which offers AC or DC power options. Arista positions the platform at about 25W per 100GbE port typical for a fully configured chassis.
