Your Springboard into the 400 Gigabit Era
In today's data-intensive world, traditional Network infrastructures quickly reach their limits. Applications such as artificial intelligence, machine learning, GPU clusters, and all-flash storage fabrics require bandwidth and latency that can hardly be managed with older 10G or 100G solutions. Bottlenecks slow down productivity and severely restrict the scalability of your IT environment. The MikroTik CRS804-4DDQ-hRM is precisely the answer to these challenges. This 400G Cloud Router Switch is a masterpiece of engineering that enables you to cost-effectively and practically enter the 400 Gigabit speed. With its four 400G QSFP56-DD ports and two additional 10 Gigabit Ethernet ports, it offers you the necessary power and flexibility to run your high-performance applications smoothly. A MikroTik that exceeds your expectations.
Maximum Flexibility: Scale Your Network Intelligently
Many 400G Switches force you into an immediate full expansion. The MikroTik CRS804-4DDQ-hRM thinks differently. Thanks to the flexible Breakout function of the QSFP-DD ports, you can split each port into multiple lower speeds – for example, into 2x 200G, 4x 100G, 8x 50G, or even 10G links. This allows you a gradual migration and scaling of your existing Network without having to replace the switch immediately. You can start with lower speeds today and switch to higher ones as needed. A cost-effective 'Future-Proofing' strategy that saves your budget and offers you maximum adaptability.
Performance Without Compromise: For the Most Demanding Workloads
The MikroTik CRS804-4DDQ-hRM is not only predestined for AI and Machine Learning clusters or high-performance storage fabrics. It also excels in specific applications such as media production, where uncompressed 8K video streaming and editing require enormous, low-latency data volumes. Even in scientific simulations that demand the highest data integrity and speed, this high-speed aggregation switch is the ideal choice. It offers you predictable, low latency and full Wire-Speed Performance to avoid bottlenecks and support your critical workloads without compromise. It is the perfect Data Center Switch for demanding environments.
More Than Just a Switch: The Power of RouterOS v7
Unlike many pure Layer 2 switches designed for 400G, the MikroTik CRS804-4DDQ-hRM runs on the powerful RouterOS v7 (license level 6). This means for you: You not only get advanced switching functions but also comprehensive routing capabilities. This opens up possibilities for more complex network architectures, extended traffic control, and seamless integration into existing MikroTik ecosystems. These extended routing functions go beyond the capabilities of many other Ethernet Switch solutions and offer significant added value for specific use cases such as Edge Compute or Service Provider Backbones. This is powered by an efficient ARM64 CPU.
Strengths & Notes at a Glance
- Pro: Extreme bandwidth density and flexibility: Offers four 400G QSFP56-DD ports in a compact 1U Rackmount form factor, which can be split into multiple 200G, 100G, 50G, 40G, 25G, 10G, 5G, 2.5G or 1G links through Breakout functions. This allows for high adaptability to existing and future network requirements and protects investments.
- Pro: High reliability and fail-safety: Equipped with dual, hot-swap redundant power supplies and hot-swap fans, ensuring uninterrupted operation in critical environments and enabling maintenance without downtime.
- Pro: Cost-efficiency and performance: Offers 400 Gigabit switching at a very competitive price compared to other 400G solutions, combined with the full functionality of RouterOS v7 for advanced traffic control, routing, and management. It delivers predictable, low latency and Wire-Speed Performance.
- Note: Not suitable for general Access Layer: The device is primarily designed for core, aggregation, and special high-performance applications such as AI clusters or Storage Fabrics. It is not an access switch for end-users and only has two 1/10G Ethernet ports, which are mainly intended for management or lower uplinks.
- Note: Special optics and cables required: To fully utilize the 400G ports or use the Breakout functions, special QSFP-DD transceivers and corresponding cables (e.g., breakout cables) are required, which may incur additional costs and are not included in the scope of delivery.
