Product overview

The HPE FlexFabric 5945 48SFP28 8QSFP28 Switch (JQ074A) is a 1U rack-mountable, fixed-port L3 managed Ethernet switch designed for data center spine and top-of-rack (ToR) deployments. It offers 48x 25GbE SFP28 ports (backward compatible to 1/10GbE) and 8x 100GbE QSFP28 ports (supporting 40GbE), delivering up to 4 Tbps switching capacity and 2024 Mpps forwarding rate. With ultra-low latency under 1μs for 64-byte packets, cut-through switching, and wire-speed performance, it handles demanding server-to-server traffic in virtualized environments. Key features include VXLAN/VTEP/OVSDB for network virtualization, HPE FlexFabric Network Analytics for real-time microburst detection, full IPv6 support, BGP/OSPF/RIP routing, ACLs, 802.1X security, and dual hot-swappable power supplies. Ideal for high-performance computing (HPC), cloud services, and multi-tenant data centers requiring scalable 25/100GbE connectivity with energy-efficient operation up to 650W max power.

Frequently asked questions

What is the switching capacity and port configuration of HPE JQ074A?

The HPE FlexFabric 5945 JQ074A offers 4 Tbps switching capacity (3.2 Tbps switch fabric) with 48x 25Gb SFP28 ports (1/10/25GbE compatible), 8x 100Gb QSFP28 ports (40/100GbE), and 2x 1Gb SFP ports. This fixed-port design supports non-blocking wire-speed forwarding up to 2024 Mpps, ideal for high-density data center ToR.

What latency does the JQ074A switch provide?

Latency is under 1μs for 64-byte packets using cut-through switching, enabling ultra-low delay for server-to-server traffic. This performance suits HPC and virtualization where microsecond-level responsiveness is critical, combined with 2504 Mpps forwarding.

Does the HPE 5945 JQ074A support network virtualization?

Yes, it includes VXLAN, VTEP, OVSDB, and NVGRE for overlay networks in virtualized data centers. Paired with HPE FlexFabric Network Analytics and IMC Virtual Fabric Manager, it detects microbursts in real-time, enhancing visibility and performance in multi-tenant cloud environments.

What management and security features are available?

Management via web GUI, SNMP, RMON, serial/USB/OOB ports. Security includes ACLs, IEEE 802.1X, SSH, SNMPv3. L2/L3 protocols: BGP, OSPF, RIP. 288K MAC table, 4GB SDRAM, 1GB flash for robust enterprise operations.

What are the power and environmental specs?

Dual hot-swappable PSUs, max 650W consumption (1381 BTU/hr heat), AC 100-240V or DC -48V. Operating 0-45°C, 5-95% RH non-condensing. 1U form factor: 43.6x440x460mm, 10.1kg weight for efficient rack deployment.
