Description

The 7800R4 36-port 800GbE OSFP line card is built for the Arista 7800R4 modular chassis family. It suits accelerated computing and AI clusters, data centre networks, and scalable routing within or between data centres, including DCI using ZR and ZR+ optics.

The card provides 36 x OSFP800 ports, configurable as up to 36 x 800G, 72 x 400G or 288 x 100G interfaces using breakouts. Throughput is 28.8 Tbps (57.6 Tbps FDX) with forwarding of up to 10.8 Bpps and latency from 3.8 microseconds. Up to 32 GB of packet buffer is available for virtual output queueing, supporting a fully scheduled, lossless architecture. This variant carries Standard FlexRoute and standard traffic policies, with no encryption. Encryption is only available on the 7800R4K variant. Typical power draw is 915 W, with a maximum of 1110 W, excluding optics.

The line card installs in DCS-7816L, DCS-7812, DCS-7808 and DCS-7804 chassis alongside the matching 7800R4 fabric modules and a supervisor module. It takes OSFP optics at 400G and 800G, including ZR and ZR+ coherent modules, and runs Arista EOS.

FAQs

Q: Does this line card include encryption?
A: No. This base 7800R4 line card has no encryption. TunnelSec is only available on the 7800R4K variant, which requires a licence file.

Q: Which chassis does it fit?
A: It installs in DCS-7816L, DCS-7812, DCS-7808 and DCS-7804 chassis. These need the matching 7800R4 fabric modules (DCS-7816LR4-FM, DCS-7812R4-FM, DCS-7808R4-FM or DCS-7804R4-FM) and a supervisor module.

Q: How much power does the line card draw?
A: Typical draw is 915 W, with a maximum of 1110 W per line card, excluding optics. It is powered from the chassis, which uses 3 kW PSUs (PWR-D1-3041-AC, PWR-D2-3041-DC or PWR-D4-3041-AC).

Q: What optics and speeds does it support?
A: The OSFP800 ports take 400G and 800G OSFP optics, including ZR and ZR+ coherent modules. Breakouts to 400G, 200G and 100G are supported.

Q: Can I upgrade an existing 7800R3 system with this card?
A: Yes. Existing 7800R3 systems can be upgraded to R4 by installing R4 fabric modules and R4 line cards.
