What port configuration does HPE JQ074-61001 provide?

The switch features 48x 25G SFP28 downlink ports for server/ToR connections and 8x 100G QSFP28 uplink ports for aggregation. SFP28 supports 1/10/25GbE transceivers; QSFP28 handles 40/100GbE, enabling flexible speeds in mixed fabrics without adapters.

What is the switching performance and latency?

Cut-through architecture provides wire-speed non-blocking forwarding across all ports with ultra-low latency under 1μs. Full-duplex throughput scales to match port densities, ideal for high-bandwidth east-west traffic in spine-leaf deployments without head-of-line blocking.

Does it support network overlays and virtualization?

Yes, native VXLAN with EVPN control plane enables L2/L3 overlays for multi-tenant clouds. Supports 16K IPv4/8K IPv6 routes, MPLS, and BGP for large-scale fabrics, reducing VTEP sprawl in VMware NSX or Kubernetes environments.

What reliability features are included?

Redundant hot-plug PSUs (650W, AC/DC), fan trays, and hitless ISSU upgrades ensure no downtime. Dual management ports, reversible airflow, and MTBF exceed 100K hours. Operates -5°C to 45°C with EN 61000 immunity standards.

Is it compatible with FCoE and storage?

Full DCB support: IEEE 802.1Qbb QCN, 802.1Qau ETS, DCBx for lossless Ethernet. Converged FCoE on 25GbE ports integrates with Brocade/FCIP fabrics, accelerating NVMe-oF without dedicated HBAs.

What management options exist?

Comware 7 OS with RESTful APIs, SNMPv3, sFlow, NetStream. CLI, web GUI, and HPE IMC integration. Supports zero-touch provisioning, telemetry for AI-driven ops, and OpenConfig for multi-vendor automation.

Product overview

The HPE FlexFabric 5945 48SFP28 8QSFP28 Switch (JQ074-61001) is a high-performance top-of-rack (ToR) solution designed for modern data centers requiring ultra-low latency and high throughput. Featuring 48x 25G SFP28 downlink ports and 8x 100G QSFP28 uplink ports, it supports cut-through switching architecture for wire-speed forwarding without blocking. This switch enables scalable spine-leaf fabrics, delivering non-blocking performance for east-west traffic in cloud, virtualization, and HPC environments. Advanced features include VXLAN for overlay networking, EVPN for control plane, and full IEEE 802.1Qbb/802.1Qau Data Center Bridging (DCB) for lossless Ethernet with FCoE support. Dual modular power supplies and fans ensure high availability with redundant hot-plug components. Compact 1U form factor (43.6x440x460mm, 10.1kg) fits dense racks, operating from -5°C to 45°C with 650W power draw. Ideal for enterprises building 25/100GbE infrastructures, it reduces latency for AI/ML workloads and storage fabrics while simplifying management via RESTful APIs and Comware OS.
