What is the switching capacity and port configuration of HPE JQ077A?

The HPE FlexFabric 5945 JQ077A delivers 6.4 Tbps full-duplex switching capacity with 32x 100GbE QSFP28 ports and 2x 1GbE SFP management ports. This non-blocking architecture supports wire-speed 100G forwarding across all ports, ideal for spine/ToR in data centers handling virtualized east-west traffic.

What latency and forwarding performance does this switch provide?

Latency is under 1 µs for 64-byte packets with cut-through switching. Forwarding rate reaches 2024 Mpps, backed by 32 MB packet buffer and 288,000 MAC address table, ensuring low-delay, high-throughput for real-time applications like HPC and cloud workloads.

Which routing and management protocols are supported?

Comware OS provides full L2/L3 features: BGP4, OSPF, RIP, IS-IS, VRRP, IGMP, plus IEEE 802.1Q, 802.3ad LACP, 802.1x. Management via CLI, SNMPv1-3, SSH, Telnet enables enterprise-scale deployment and monitoring.

Is the JQ077A suitable for telecom environments?

Yes, NEBS certified with PTP 1588v2 boundary/transparent clock support, dual AC/DC power inputs (100-240V AC or -40 to -72V DC), and high MTBF for carrier-grade reliability in edge deployments.

What are the physical dimensions and power requirements?

1U rack-mountable at 1.72" H x 15.75" W x 18.11" D, weighing 28.88 lbs. Supports 2 power supplies with 650W max consumption, operating across wide voltage ranges for data center flexibility.

How does it support modern data center overlays?

VXLAN, EVPN, and MPLS enable network virtualization for multi-tenant clouds. Combined with 100GbE density, it scales spine-leaf fabrics for server-to-server traffic in hyper-converged infrastructures.
