MikroTik Cloud Router Switch CRS804-4DDQ-hRM

Designed for demanding data flows, AI clusters, and modern backbone infrastructures where throughput and latency are critical. Four 400G QSFP-DD ports in a silent 1U form factor provide exceptional performance density for aggregation and GPU nodes. The combination of Marvell switching chip with quad-core 2 GHz ARM CPU and 4 GB RAM ensures full switching speed, advanced traffic management, and stable operation even under full load. Flexible breakout scenarios allow easy splitting of 400G ports into 200G, 100G, or 40G links, seamlessly integrating into existing infrastructure.

Reliability, efficiency, and future readiness

The device is built for long-term operation with minimal costs. Dual hot-swap power supplies and replaceable fans increase availability, while a consumption of only 123 W in full configuration with optics saves energy and cooling. The operating system RouterOS v7 (level 6) offers a proven environment, advanced features, and easy management. An ideal choice for smaller data centers, enterprise floors, and edge deployments where maximum speed is required in a limited space.
