What is the switching capacity and latency of HPE JQ075A?

The HPE FlexFabric 5945 2-Slot Switch (JQ075A) provides 3.6 Tbps routing/switching capacity and <1 µs latency for 64-byte packets, with up to 2024 Mpps throughput. This non-blocking architecture supports wire-speed 100GbE forwarding, ideal for spine/ToR deployments in high-throughput data centers.

What port configurations does the JQ075A support?

It features 2 module slots and 2x 100Gb QSFP28 ports, expandable to 48x 10/25GbE + 4x 100GbE or up to 16x 100GbE via modules. Additional interfaces include 2x management RJ-45, console RJ-45, USB 2.0, and mini-USB.

Does JQ075A support stacking and virtualization?

Yes, supports Intelligent Resilient Framework (IRF) stacking up to 9 units for simplified management. VXLAN with OVSDB enables dynamic overlay tunnels for network virtualization, enhancing flexibility in cloud and SDN environments.

What routing protocols are supported on this switch?

Supports OSPF, BGP-4, IS-IS, RIP-1/2, IGMP, VRRP, ECMP, static IPv6, MPLS, BFD, RIPng, IPv6 IS-IS, and BGP+. IPv4 routing table holds 324K entries; IPv6 holds 162K.

What power and environmental specs does it have?

Dual hot-plug 650W internal PSUs with redundancy, AC 100-240V or DC -48 to -60V input. 1U rack-mountable (44.2x440x660mm), 10.4kg weight, 1392 BTU/hr heat dissipation.

Is JQ075A suitable for converged infrastructure?

Yes, with Data Center Bridging (DCB), FCoE forwarding, and 32MB packet buffer. Supports LACP, QoS, jumbo frames up to 9416 bytes, making it ideal for storage and compute convergence.
