MikroTik CRS804 DDQ in Dubai, UAE
The MikroTik CRS804 DDQ is a compact 1U switch built for organisations that need four 400G QSFP56-DD ports without moving to a large chassis platform. It is suited to AI clusters, all-flash storage fabrics, laboratory networks, high-speed aggregation and compact data-centre designs where bandwidth density, rack efficiency and flexible breakout options matter.
Platform: RouterOS v7, License Level 6
Primary role: 400G switching and aggregation
Direct answer for buyers
The MikroTik CRS804 DDQ is a managed high-speed switch with four 400G QSFP56-DD ports, two multi-rate Ethernet ports capable of 10G operation, RouterOS v7 and a compact rack format. Its main purpose is to create a dense switching layer for GPU systems, storage nodes, research platforms, media workflows and high-speed aggregation. It should be considered by buyers who already understand their required link speeds, cable types and endpoint interfaces. Before proceeding, confirm whether each connection will run at native 400G or use breakout modes, whether the intended optics or direct-attach cables are supported, how the switch will be mounted, and whether the network design needs redundancy beyond the included dual power supplies.
What it does
The CRS804 DDQ concentrates very high bandwidth into a compact switch. Each of its four QSFP56-DD ports can operate as a high-capacity interface for 400G links and can also be used with supported breakout configurations for lower-speed connections. This allows the device to work as a compact spine, storage-fabric switch, AI-cluster interconnect or aggregation point where a small number of extremely fast links is more useful than a large number of lower-speed access ports.
Who it suits
This model is most relevant to data-centre teams, AI infrastructure builders, systems integrators, storage architects, research laboratories, media-production environments and enterprises planning high-speed east-west traffic. It is not intended as a conventional office access switch. Buyers should have a defined topology, known endpoint capabilities and a clear transceiver or cable plan before deployment.
Business problems the CRS804 DDQ helps address
Bandwidth bottlenecks between compute nodes
AI and scientific workloads can move large datasets between accelerators, hosts and shared storage. A low-capacity switching layer can restrict the effective performance of expensive compute resources. Four 400G ports provide a compact path for high-bandwidth node and fabric connections when the rest of the system is designed to use them.
Limited rack space
The device uses a half-width 1U form factor and includes hardware for single-device or side-by-side rack installation. This can help smaller facilities, test labs and edge-compute sites build a 400G fabric without allocating a full-depth chassis platform.
Mixed-speed migration
Not every connected system will move to 400G at the same time. Supported breakout options allow high-density ports to serve lower-speed links where the correct cable, optic and configuration are used. This makes phased migration possible, although each endpoint and breakout design must be validated.
Power and component continuity
Dual hot-swap power supplies and two hot-swap fans support serviceability in environments that cannot accept unnecessary interruption. Redundant power design is useful, but the overall power path still depends on separate circuits, PDU design and upstream electrical resilience.
Core capability band
Product-fit matrix
| Requirement | Suitable when | Confirm before ordering |
|---|---|---|
| AI or GPU cluster | A small or medium cluster needs a compact high-speed fabric. | GPU NIC speed, cable type, topology, oversubscription and protocol requirements. |
| All-flash storage | Storage nodes require 200G or 400G uplinks and low switching overhead. | Storage protocol, NIC support, MTU, latency expectations and redundancy design. |
| High-speed aggregation | Several lower-speed links must be consolidated into a small backbone. | Breakout mapping, optics, fibre type, distance and port-channel design. |
| Compact data-centre pod | Rack space and power efficiency are important. | Airflow, mounting method, power feeds and maintenance access. |
| General office access | Usually not the right fit because it lacks a large quantity of copper access ports. | Consider a lower-speed access-switch family instead. |

Compatibility and configuration dependencies
A 400G port does not by itself guarantee that every optic, cable or connected device will work in every mode. Buyers must verify the transceiver type, breakout standard, cable length, fibre grade, endpoint form factor, speed negotiation and RouterOS configuration. Breakout designs can create two 200G links or multiple lower-speed links, but the exact supported combination depends on the cable assembly and connected hardware.
For storage and AI fabrics, confirm MTU, link aggregation, traffic distribution, VLAN architecture and any protocol-specific requirements. The CRS804 DDQ is a powerful switching platform, but application performance also depends on server NICs, drivers, storage architecture, topology and workload behaviour. FourTeck can review the intended connection map before the bill of materials is finalised.
Purchase and deployment journey
Define the traffic objective
Identify whether the switch will serve GPU nodes, storage arrays, a spine layer, a test platform or a migration project. Document expected link speeds, traffic direction and redundancy requirements.
Build the physical connection map
List each endpoint, interface type, speed, distance and connector. This determines whether native QSFP56-DD optics, direct-attach cables or breakout assemblies are appropriate.
Confirm rack and power design
Decide whether one unit will occupy a 1U position or two units will be mounted side by side. Verify airflow, PDU capacity, separate power feeds and service access.
Prepare the RouterOS configuration
Plan management access, firmware version, VLANs, bridge settings, port breakout, monitoring, authentication and backup. Apply configuration in a controlled staging environment where possible.
Test before production cutover
Validate every link speed, breakout mapping, error counter, redundancy path, throughput target and monitoring alert. Record the final port map and configuration for support and future changes.
Dense 400G switching without a chassis
The main appeal of the CRS804 DDQ is concentrated bandwidth. Four native 400G interfaces allow the switch to move large volumes of east-west traffic in a very small footprint. This is valuable where the network contains only a few critical high-speed endpoints rather than dozens of access ports. A buyer should compare the number of required fabric links against the four-port limit and consider whether a second switch is needed for growth or redundancy.
Breakout flexibility for staged migration
Each QSFP56-DD interface consists of multiple high-speed lanes. With suitable breakout hardware, a port can serve lower-speed connections instead of a single native 400G link. This is useful when some servers operate at 200G, 100G, 50G, 25G or another supported rate. The operational benefit is flexibility, but the planning burden is higher because lane mapping, cable choice and endpoint compatibility must be checked carefully.
RouterOS control and serviceability
RouterOS v7 gives network teams a familiar interface for configuration, monitoring and software maintenance. Dual hot-swap power modules and replaceable fans support serviceability in rack environments. These features reduce maintenance friction, but a resilient design still requires configuration backups, tested spare procedures, power-path separation and change control.
Ideal business environments and use cases
AI laboratories and private GPU clusters
Suitable for a compact fabric connecting a small number of high-speed compute nodes, management networks and storage resources. Confirm whether the target workload requires Ethernet switching features supported by the design.
All-flash storage networks
Useful where servers and storage arrays need very high throughput for database, media, analytics or scientific datasets. Validate latency, packet-loss sensitivity and storage-protocol requirements before final selection.
Media production and rendering
Large video assets and render workloads can benefit from fast movement between workstations, render nodes and shared storage. The physical cabling design should reflect distance and fibre requirements.
Research and test environments
The compact platform is relevant to universities, engineering labs, telecom testbeds and network-development teams experimenting with 200G and 400G connectivity.
Operational and integration considerations
A successful 400G deployment starts with the endpoints. Network interface cards, transceivers, drivers and operating systems must support the target link modes. A connection shown as physically possible may still require specific firmware or lane configuration. Review the MikroTik compatibility guidance and the connected vendor’s interface documentation before purchasing optics or cables.
Cooling also deserves attention. Although the CRS804 DDQ is compact and designed for efficient operation, 400G optics can create significant heat. Keep the rack airflow path unobstructed and verify that the room can maintain the required operating temperature. Where two switches are mounted side by side, ensure that cabling does not block ventilation or fan replacement.
Management planning should include a dedicated IP plan, secure administrator access, software updates, configuration backups and monitoring. The two RJ45 interfaces are marked for management and boot functions, but the actual design should reflect the customer’s operational policy. For critical fabrics, document out-of-band access and recovery steps before production deployment.
The CRS804 DDQ should be considered part of a complete system rather than a standalone performance guarantee. Effective throughput depends on traffic patterns, packet size, endpoint capability and application behaviour. FourTeck can help translate the intended workload into a practical connection plan and quotation.
Buyer questions to resolve before ordering
Native 400G, dual 200G and lower-speed breakout designs require different cables and port settings. Define the complete port map first.
Direct-attach copper, active optical cables and pluggable optics suit different distances and rack layouts.
A single unit provides four fabric ports. Growth, dual-homing and maintenance requirements may justify two switches.
Clarify whether the quotation should include optics, breakout cables, rack installation, RouterOS configuration, testing and documentation.
