Description

The Arista 7368X4 switch card is the 12.8 Tbps single-packet-processor core of the 7368X4 4RU modular data centre switch. It suits leaf and spine roles in large-scale cloud and hyper-scale networks, including AI and ML clusters, big data farms and high-density 100G and 400G aggregation.

This front-to-rear airflow variant includes its fans and delivers 12.8 Tbps and 8 Bpps of throughput with latency from 700 ns. It carries 64 MB of dynamically allocated packet buffer and connects fully to all 8 I/O module slots at 3.2 Tbps per slot with no oversubscription. Typical and maximum power draw is 204 W and 364 W, and the card runs Arista EOS 4.22.0 or later. Feature licences from the LIC-FIX-3 group are ordered separately.

It is designed for the DCS-7368-CH chassis alongside the DCS-7368-SUP or DCS-7368-SUP-D supervisor and the DCS-7368-16S, DCS-7368-16C, DCS-7358-16C, DCS-7368-4D and DCS-7368-4P I/O modules. Airflow must match the other components, so use -F fans and power supplies for front-to-rear. The rear-to-front equivalent is DCS-7368X4-SC-R.

FAQs

Q: Which chassis does the DCS-7368X4-SC-F fit?
A: It is built for the Arista DCS-7368-CH chassis and requires EOS 4.22.0 or later. It works with the DCS-7368-SUP or DCS-7368-SUP-D supervisor.

Q: Which I/O modules can I use with it?
A: It supports the DCS-7368-16S (25G SFP28), DCS-7368-16C and DCS-7358-16C (100G QSFP28), DCS-7368-4D (400G QSFP-DD) and DCS-7368-4P (400G OSFP) modules.

Q: What is the difference between the -SC-F and -SC-R?
A: The -SC-F has front-to-rear airflow and includes fans. The DCS-7368X4-SC-R is the rear-to-front variant. Airflow must match the other chassis components.

Q: What power does the switch card draw?
A: Typical draw is 204 W and maximum is 364 W. The chassis takes up to four 1900W AC or DC hot-swap power supplies in N+N redundancy, using the -F models for front-to-rear airflow.

Q: Does it need a software licence?
A: It runs Arista EOS, and feature licences from the LIC-FIX-3 group, such as LIC-FIX-3-E for Enhanced L3, are ordered separately.
