MIKROTIK Cloud Router Switch CRS804 DDQ with RouterOS L6

The CRS804 DDQ is a compact and reliable 400 Gigabit switch designed for modern AI workloads and next-generation network upgrades. With four 400G QSFP-DD ports and dual 1/10G Ethernet, it delivers exceptional bandwidth density in a quiet and efficient 1U form factor.Inside, a Marvell 98DX7335 switch chip works together with a hefty quad-core 2.0 GHz ARM CPU, 4 GB of DDR4 RAM, and RouterOS v7. This provides advanced traffic control, high performance switching, and a familiar management environment trusted by users worldwide.The CRS804 DDQ is designed for long-term reliability and low cost of ownership, supported by hot-swap power supplies (included!), robust cooling, and low power consumption that reaches only 123 W at full load with optics installed.AI and GPU clustersA perfect building block for small to medium AI installations. It delivers predictable, low-latency performance and full wire-speed switching, keeping GPU nodes and storage traffic flowing without bottlenecks. The compact design and low power usage make it suitable for AI labs, research environments, and smaller rack deployments.Future proofing for existing networksThe CRS804 DDQ can act as a high speed core or aggregation switch even in older racks. Each 400G QSFP-DD port is built from eight independent data lanes. This enables flexible breakout options, including two 200G links for AI workloads or lower-speed connections such as 100G or 40G. You can deploy the CRS804 DDQ in your existing network today and upgrade to higher speeds over time without replacing the switch. With the right breakout cables, the CRS804 DDQ can interconnect virtually any device with SFP or QSFP ports, regardless of generation.All-flash storage fabricsUse native 400G ports for fast storage uplinks or split them into dual 200G links. Ideal for media production, scientific workloads, and any environment where rapid data movement is essential.
