Introducing the DBETE-5X 50G Series, engineered to bring high-performance, flexible buffering to cost-sensitive access and aggregation layers. These switches deliver 32 ports of 50G connectivity, massive 24K MAC scale, and a deep 31 Mbit Flexible (F) Buffer to ensure lossless transport for demanding applications.

Choose the DBETE-5X/50G24K31F1V for large-scale segmentation, featuring support for 4,000 VLANs to cleanly isolate users, devices, and services in enterprise or campus networks. Choose the DBETE-5X/50G24K31F1M for operational intelligence, leveraging its 1 MB on-chip telemetry cache to gain deep visibility into application flows and performance bottlenecks.

These switches are ideally deployed as high-density Top-of-Rack (ToR) leaf switches or as aggregation switches in enterprise, campus, and medium-scale cloud environments. They provide a balanced combination of 50G performance, deep buffering for lossless traffic, and a choice between extensive VLAN segmentation or advanced performance monitoring.

The 31 Mbit Flexible (F) buffer is exceptionally deep for a 50G platform. It is critical for handling traffic bursts and microbursts that commonly occur when aggregating traffic from many 10G/25G servers. This prevents packet loss and TCP retransmissions, ensuring smooth performance for storage traffic and virtual machine migration, even in highly consolidated environments.

For a large enterprise campus network, the DBETE-5X/50G24K31F1V (1V model) is typically the better choice. Its support for 4,000 VLANs allows network architects to implement granular segmentation for different buildings, departments, and device types across a large layer-2 domain, all while maintaining high performance and congestion management.

At the 50G aggregation layer, the 1 MB telemetry cache in the 1M model provides a powerful tool for application performance management. It can identify "noisy neighbor" problems, pinpoint the source of application latency, and validate quality of service (QoS) policies. This is invaluable for troubleshooting performance issues in consolidated environments running voice, video, and data over a shared 50G uplink.

Yes, with high flexibility. The 50G QSFP28 ports on both models support industry-standard breakout cabling. A single 50G port can break out into 2x 25G or 4x 10G connections using a breakout cable or module, allowing you to connect directly to servers. The switches can also use 50G ports natively or aggregate them to form high-bandwidth 100G/200G uplinks to the network core.
