HPE JG555A

FlexFabric 5920AF‑24XG TAA 24‑Port 10 Gb/s SFP+ Ethernet Switch Module

The HPE FlexFabric 5920AF‑24XG switch module (model JG555A) delivers 24 high‑density 10 Gb SFP+ access ports plus 4 QSFP+ uplinks (40 GbE) in a compact 1 RU design with front‑to‑back airflow. Designed for scale‑out server-edge deployments, this module forms the backbone of HPE Composable Fabric or FlexFabric data center fabrics. With enterprise-grade QoS, IRF virtualization, and up to 480 Gbps switching capacity, it supports high-throughput, low-latency server connectivity ideal for virtualization, storage, and converged Ethernet applications.

Features

Part of the HPE FlexFabric 5920 series, the JG555A provides ultra‑deep packet buffering (3.6 GB) and cut‑through switching to deliver latency under 1 microsecond, with a full throughput of 480 Gbps and 367 Mpps forwarding capacity . It runs Comware v7 modular OS with support for L2/L3 routing, VXLAN/NVGRE overlays, and large routing/MAC tables—up to 4096 VLANs and 128k MAC addresses . Supports HPE Intelligent Resilient Framework (IRF) to group up to four units into a resilient 2-tier fabric topology that simplifies management, reduces fabric complexity, and enables high availability

Advanced Options

The JG555A excels in dense rack environments demanding high port density and low latency. Its cut‑through architecture maintains forwarding delays under 1 μs—even under bursty SAN, storage, or virtualization traffic—while deep buffering avoids packet drops during peak loads
