The MikroTik CRS804 DDQ Cloud Router Switch (CRS804-4DDQ-hRM) is a compact 400 Gigabit Ethernet switch designed for AI and GPU clusters, all-flash storage fabrics, high-speed aggregation, and next-generation network upgrades. Four QSFP-DD ports provide high-density connectivity at speeds up to 400 Gbps, while two Ethernet ports support 1G, 2.5G, 5G, and 10G connections.
A Marvell 98DX7335 switch chip delivers wire-speed switching across the ports, while a quad-core 2 GHz ARM processor, 4 GB of DDR4 RAM, and RouterOS v7 provide advanced traffic control, routing, switching, and network management. Flexible breakout support allows the CRS804 DDQ to connect with existing lower-speed SFP and QSFP equipment while supporting future upgrades to 200G and 400G.
