Description

The DCS-7368-4P is a 4-port 400GbE OSFP interface module for the Arista 7368X4 Series modular data centre switch chassis. It adds 400G, 200G or 100G capacity to a 7368X4 system and suits leaf or spine roles in hyperscale cloud, AI/ML cluster, big data and server-less compute networks.

Each module provides 4 x OSFP ports, configurable as up to 4 x 400GbE, 8 x 200GbE or 16 x 100GbE using OSFP optics and breakout cables. It connects directly to the switch card with no oversubscription, giving 3.2 Tbps of capacity per slot. Typical power draw is 72 W, with a maximum of 140 W when 20W optics are fitted to every port. This is the OSFP version, distinct from the DCS-7368-4D QSFP-DD module, and it supports front-to-rear airflow only. The module is hot-swappable and can be mixed with 25G, 100G, 200G and 400G modules in the same chassis.

It works in the DCS-7368-CH chassis with a DCS-7368-SUP or SUP-D supervisor and a DCS-7368X4-SC switch card, and needs EOS 4.24.1 or later. The OSFP ports support 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, 2FR4 and LR4 optics, as well as OSFP-to-QSFP and OSFP-to-SFP breakout DACs.

FAQs

Q: Does this module need its own licence?
A: No licence is needed for the module itself. EOS feature licences from the LIC-FIX-3 family are ordered separately for the chassis.

Q: Which chassis and components does it work with?
A: It works only in the DCS-7368-CH chassis with a DCS-7368-SUP or SUP-D supervisor and a DCS-7368X4-SC switch card, running EOS 4.24.1 or later.

Q: How much power does the module draw?
A: Typical draw is 72 W and the maximum is 140 W per module, excluding optics. The maximum figure assumes 20W optics on all ports.

Q: How does it differ from the DCS-7368-4D?
A: The DCS-7368-4P provides 4 x 400G OSFP ports, while the DCS-7368-4D uses QSFP-DD ports. Choose the one that matches your optics and cabling.

Q: Which optics and breakout cables do the OSFP ports support?
A: The ports support 400GBASE-CR8, AOC, SR8, DR4, XDR4, FR4, 2FR4 and LR4, plus OSFP-to-2xQSFP breakout DACs for 200G, 100G and 50G and OSFP-to-8xSFP breakout DACs for 25G.
