CRS804-4DDQ-hRM Cloud Router Switch RouterOS v7

Mikrotik CRS804-4DDQ-hRM Cloud Router Switch RouterOS v7

The CRS804 DDQ is a compact and reliable 400 Gigabit mainboard designed for modern AI workloads and new-generation network upgrades. It offers exceptional bandwidth density in a 1U form factor with four 400G QSFP-DD ports and dual 1/10G Ethernet.

Equipped with a powerful quad-core 2.0 GHz ARM CPU, 4 GB DDR4 RAM, and a Marvell 98DX7335 switching chip running RouterOS v7, it provides advanced traffic control, high-performance switching, and a familiar management environment trusted by users worldwide.

Designed for long-term reliability and low operational costs, the CRS804 DDQ features replaceable power sources (including!), robust cooling, and consumes only 123 W at full load, making it suitable for applications requiring low power consumption.

AI and GPU Clusters
A perfect building block for small and medium-scale AI setups. It offers predictable, low-latency performance and non-blocking switching at full cable speed, ensuring smooth data flow for GPU nodes and storage traffic. Its compact design and low power consumption make it suitable for AI labs, research environments, and smaller rack setups.

Future-Proof for Existing Networks
The CRS804 DDQ can operate as a high-speed core or aggregation switch even in legacy racks. Each 400G QSFP-DD port consists of eight independent data lanes, providing flexible connection options, including two 200G links or lower-speed connections like 100G or 40G. You can deploy the CRS804 DDQ in your current network today and upgrade to higher speeds over time without changing the switch. With the right cable connections, the CRS804 DDQ can connect almost any device with SFP or QSFP ports.

Totally Flash-Based Storage Networks
Use the local 400G ports for fast storage connections or split them into dual 200G links. Ideal for media production, scientific workloads, and environments requiring fast data transfer.

Compact 400G Network Structures in Limited Rack Space
Create a powerful backbone or core network structure using four 400G ports. Perfect for small data centers, enterprise modules, edge computing setups, and environments where traditional 400G equipment would be too noisy, large, or expensive.
