Description

The Arista DCS-7368-4P is a high-density interface module for the 7368X4 Series modular data center switches, delivering four 400GbE OSFP ports with support for multi-speed operation including 4x100G and 2x200G breakout modes. Designed for hyperscale cloud, AI, and machine learning environments, this hot-swappable module integrates seamlessly into the 7368X4 chassis to enable up to 32x400G or 128x100G configurations in a compact 4RU system. Ideal for leaf-spine data center architectures requiring ultra-low latency and high-density 400G connectivity.

FAQs

Q: Is the DCS-7368-4P compatible with other Arista switch series?
A: No, the DCS-7368-4P is specifically designed for the Arista 7368X4 Series modular chassis and requires the 7368X4-SC switch card. It is not compatible with fixed switches or other modular platforms.

Q: Can I mix different module types in the same 7368X4 chassis?
A: Yes, the 7368X4 chassis supports mix-and-match configurations with various interface modules including 400G OSFP, 400G QSFP-DD, 100G QSFP, and 25G SFP28 modules across the eight available slots for flexible deployment.

Q: What breakout modes are supported on the 400G OSFP ports?
A: Each 400G OSFP port on the DCS-7368-4P supports multiple breakout configurations including native 400G operation, 4x100G breakout for backward compatibility with 100G infrastructure, and 2x200G breakout for 200G connectivity.

Q: Is the module hot-swappable for maintenance operations?
A: Yes, the DCS-7368-4P is hot-swappable, allowing installation or removal without powering down the chassis or disrupting other active modules, supporting cloud-optimized operational workflows.

Q: What use cases are ideal for this 400G module?
A: The DCS-7368-4P is optimized for high-density data center spine and leaf deployments, AI/ML cluster networking, hyperscale cloud environments, and large-scale service provider networks requiring ultra-low latency and high bandwidth per port.
