Datacom has launched the DM4820 32CX, a new 1RU network switch designed for data center leaf-and-spine architectures. The hardware is now available for deployment with configurable airflow options.
Why it matters
The DM4820 32CX provides a flexible high-density switching option for modern data center server topologies, allowing for varied uplink and downlink port configurations.
The device features 32 QSFP28 ports capable of 100 Gbps throughput, with support for breakout into four 25 or 10 Gbps interfaces and two supplemental 10 Gbps SFP+ ports. It occupies a 1RU form factor and is available with either front-to-back or back-to-front airflow.
The players
Datacom
A provider of enterprise networking hardware focusing on high-density switching solutions for data center environments.
The details
The DM4820 32CX is built for leaf-and-spine topologies, a common data center network design where leaf switches connect to servers and spine switches aggregate traffic to ensure low-latency communication. By utilizing a 1RU (1 rack unit — a standard measurement for server equipment height) form factor, the switch minimizes physical space in server racks. The unit allows administrators to choose their airflow configuration at deployment to match existing hot-aisle or cold-aisle containment strategies.

The Tech Race
This release follows the industry trend toward higher port density within compact 1RU server hardware to support increasing bandwidth demands. It competes with established leaf-and-spine hardware platforms by offering configurable cooling paths and multi-speed breakout options.
Data center operators can deploy the DM4820 32CX immediately to scale their leaf-and-spine connectivity using its 100 Gbps QSFP28 ports. The switch supports both front-to-back and back-to-front airflow, making it compatible with diverse cooling infrastructure already installed in existing facilities.
The takeaway
The DM4820 32CX targets the specific need for flexible, high-density port configurations in modular server environments. Operators should evaluate their existing rack cooling paths to determine if the front-to-back or back-to-front model fits their specific thermal management strategy.
