HPE JH391A 5940 Flex fabric Managed Ethernet switch 48 Ports

The HPE JH391A is a high-performance, low-latency Layer 3 data center switch designed for top-of-rack or aggregation layer deployments. It addresses the need for scalable, high-density 10GbE server connectivity and 100GbE uplinks in enterprise data centers, cloud environments, and medium-to-large campus networks. The switch is engineered to handle demanding workloads and the increasing data volumes driven by virtualization and converged infrastructure. This switch provides an advanced feature set based on the Comware 7 operating system. Key technologies include Hewlett Packard Enterprise Intelligent Resilient Fabric (IRF), which allows up to nine switches to be managed as a single logical device, significantly simplifying network administration and improving resiliency. The ultra-low latency of under one microsecond for 10GbE traffic makes it an ideal solution for latency-sensitive applications, such as high-frequency trading and high-performance computing clusters. Designed for deployment at the server access or aggregation layer, the JH391A fits into a compact 1U rack-mountable form factor. Management is streamlined through the HPE Intelligent Management Center (IMC), providing a comprehensive platform for network oversight. Its combination of high-density copper ports and high-speed fiber uplinks offers a versatile and powerful foundation for modern network architectures.
