MikroTik Cloud Router Switch 804-4DDQ-hRM

Compact 1U 400G switch for AI clusters, storage fabrics, and high-speed aggregation.

The CRS804 DDQ is a powerful 1U 400 Gigabit switch designed for modern AI environments, storage networks, and high-speed core or aggregation deployments. With four 400G QSFP56-DD ports and two 1/10 GbE Ethernet ports, it delivers extreme bandwidth in a compact and energy-efficient form factor. A Marvell switch chip combined with a quad-core ARM CPU and RouterOS v7 enables wire-speed switching and advanced network features.

Each 400G port supports breakout into lower-speed links such as 2x 200G or multiple 100G connections, allowing easy integration with existing infrastructure and future scalability. Hot-swap power supplies, active cooling, and low power consumption make the CRS804 DDQ suitable for continuous operation in data center and edge environments. The included rackmount kit even allows two switches to be installed in a single 1U rack slot for maximum port density.
