What is the port configuration and performance of HPE JH395A?

JH395A features 48 fixed 1/10 Gigabit SFP+ ports and 6x 40 Gigabit QSFP+ ports in a 1U chassis. It delivers 1440 Gbps switching/routing capacity, 1071 Mpps throughput, and <1 µs latency for 10G traffic, enabling wire-speed non-blocking forwarding across all ports.

Does the JH395A support network virtualization?

Yes, hardware VXLAN support provides Layer 2 and Layer 3 gateway functions for up to 4000 tunnels, ideal for overlay networks in cloud and virtualized data centers with seamless multi-tenancy.

What stacking capabilities does this switch offer?

Intelligent Resilient Framework (IRF) enables stacking up to 9 units into a single logical switch, simplifying management, enhancing redundancy, and providing virtual stacking for simplified topologies.

What are the power and cooling requirements?

Requires minimum 1 hot-plug PSU (e.g., JC680A 650W) and 2 fan trays. Typical consumption 85W under load with dual redundant PSUs. Back-to-front airflow supports high-density rack cooling.

Is JH395A suitable for high-performance computing?

Yes, with 1.44Tbps capacity, sub-microsecond latency, and jumbo frame support to 10K bytes, it excels in HPC clusters requiring low-latency east-west traffic and high-throughput server interconnects.

What management interfaces are available?

Includes 1x RJ-45 console, 1x OOB management Ethernet, USB 2.0, and supports Telnet, CLI, SNMP. Runs Comware OS with 4GB DRAM and 1GB flash for advanced L3 features.
