Description

The HPE Broadcom BCM57608 is a dual-port 100Gb Ethernet OCP 3.0 network adapter designed for HPE ProLiant servers running enterprise, cloud, and hyperscale data centre workloads. Powered by the Broadcom BCM57608 ASIC over a PCIe 5.0 x16 interface, it delivers up to 200Gb aggregate throughput with auto-negotiation across 25/50/100Gb speeds, RoCEv2 RDMA for ultra-low-latency storage and compute traffic, and SR-IOV with 128 Virtual Functions for dense virtualisation deployments.

The OCP 3.0 mezzanine form factor enables tool-less integration into compatible HPE ProLiant servers, keeping cable clutter to a minimum. Advanced offload capabilities including VXLAN, NVGRE, and GENEVE tunnel offload, DPDK support, and VMware NetQueue/Microsoft VMQ make this adapter equally at home in software-defined networking and NFV environments. Hardware Root of Trust, authenticated firmware updates, Secure Boot, and Audit Log support meet modern enterprise security requirements. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

Features

- Dual QSFP112 ports delivering 100Gb/s per port (200Gb aggregate) with 25/50/100Gb auto-negotiation
- PCIe 5.0 x16 host interface for maximum throughput with next-generation HPE ProLiant platforms
- RoCEv2 RDMA support for low-latency, high-throughput storage (NVMe-oF) and HPC traffic
- SR-IOV with 128 Virtual Functions and NPAR (8 PFs per port) for dense multi-tenant virtualisation

FAQs

Q: Which HPE servers is the P73114-B21 compatible with?
A: The P73114-B21 is designed for HPE ProLiant servers that feature an OCP 3.0 mezzanine slot. Refer to HPE's server compatibility matrix or contact IP Trading to confirm compatibility with your specific ProLiant model before ordering.

Q: What is the advantage of the OCP 3.0 form factor over a standard PCIe card?
A: OCP 3.0 adapters mount directly into a dedicated mezzanine slot inside the server, eliminating external cabling and PCIe riser brackets. This improves airflow, reduces installation time, and keeps the standard PCIe slots free for other expansion cards.

Q: Does this adapter support RDMA for storage or HPC workloads?
A: Yes. The BCM57608 supports RoCEv2 (RDMA over Converged Ethernet v2), enabling high-throughput, low-latency data transfer suitable for NVMe-oF storage, AI/ML distributed training, and high-performance computing workloads.

Q: How many virtual machines or containers can share this adapter?
A: The adapter supports Single Root I/O Virtualisation (SR-IOV) with up to 128 Virtual Functions (VFs) and NPAR with 8 physical functions per port (16 per board), allowing a large number of VMs or containers to share the 100Gb bandwidth with hardware-level isolation.

Q: What security features does the BCM57608 OCP3 adapter include?
A: The adapter includes Hardware Root of Trust with SPDM support, authenticated firmware updates, Secure Boot, Audit Log capability, and Sanitisation support for secure data disposal — meeting stringent enterprise and government security requirements.

Q: Can I purchase the HPE P73114-B21 in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian-owned and operated IT hardware reseller with over 20 years of experience. You can order the P73114-B21 directly through our website or contact our team for volume pricing and compatibility advice.
