The MikroTik CRS504-4XQ-IN is a compact switch with four 100 Gbps QSFP28 ports that opens the 100G tier without a rack full of equipment and the matching budget. Total capacity is 400 Gbps in a desktop enclosure with passive cooling and low power consumption: the device needs neither a rack nor dedicated heat removal. RouterOS handles management — routing, VLANs and a firewall run on the same hardware with no extra licenses.
Typical roles for the device are the core of a small data center, inter-rack links and backbones between buildings. When needed, each QSFP28 port splits into four 25 Gbps lanes with a breakout cable: four physical ports become sixteen logical connections for virtualization servers and storage systems. At these speeds the network stops being the bottleneck for NVMe storage.
Advantages
- Four QSFP28 ports at 100 Gbps each — 400 Gbps in total
- 4×25G breakout: up to sixteen logical connections
- Passive cooling — no noise, no forced ventilation
- Low power consumption for the 100G class
- RouterOS: routing, VLANs and firewall on board
- Redundant power, including DC for telecom racks
Applications
- Core of a small data center
- Aggregation between server racks
- Backbones between buildings
- Connecting storage systems and virtualization servers
Installation and setup
The switch sits on a shelf, a desk or in a rack next to the servers; passive cooling only needs a gap for natural convection. Links are built with QSFP28 transceivers or DAC/AOC assemblies, and breakouts with 100G to 4×25G splitter cables. Initial configuration is done via WinBox or the RouterOS console: VLANs are created and, if required, routing between segments is enabled. In a typical design the CRS504 aggregates access switches and servers with 25G adapters, terminating the rack's traffic. The device is in stock in Tashkent — we can help choose transceivers and plan the network topology.
