Broadcom Emulex OneConnect OCe15104-NM 100GbE Converged Network Adapter

The Broadcom Emulex OneConnect OCe15104-NM is a quad-port 100 Gigabit Ethernet Converged Network Adapter engineered for enterprise data centers requiring unified storage and networking fabric at extreme bandwidth densities. Built on Broadcom's latest Lancer ASIC architecture, the adapter integrates full hardware offload engines for FCoE (Fibre Channel over Ethernet) and iSCSI protocols alongside standard NIC functionality, eliminating the need for separate HBAs or iSCSI initiator cards. The PCIe 4.0 x16 host interface ensures the adapter can sustain line-rate throughput across all four 100GbE ports simultaneously without becoming host-bus bound, making it particularly well-suited for NVMe-oF, high-frequency block storage access, and latency-sensitive distributed workloads.

The OCe15104-NM leverages Broadcom's intelligent offload pipeline to handle TCP/IP, FCoE, and iSCSI processing entirely in silicon, dramatically reducing CPU utilization in storage-intensive virtual machine environments. Features including Large Send Offload (LSO), Large Receive Offload (LRO), VXLAN and NVGRE tunneling offload, and hardware-based RSS (Receive Side Scaling) enable the adapter to sustain high connection counts across multi-tenant workloads such as VMware vSphere, Microsoft Hyper-V, and Red Hat KVM hypervisor stacks. RDMA over Converged Ethernet (RoCEv2) support is integrated natively, enabling ultra-low latency memory-to-memory transfers critical for in-memory databases and high-performance computing clusters.

Designed and validated for HPE ProLiant Gen11 and Dell PowerEdge Gen15 rack server platforms, the OCe15104-NM ships with comprehensive driver support for Windows Server 2022, RHEL 9.x, SLES 15, and VMware ESXi 8.x. The adapter is compliant with IEEE 802.3ba 100GbE, IEEE 802.1Qbb Priority Flow Control, and IEEE 802.1Qaz ETS standards, ensuring drop-free lossless fabric operation required by FCoE SAN environments. Management integration spans Broadcom's OneCommand Manager utility, IPMI/BMC out-of-band visibility, and compatibility with HPE iLO and Dell iDRAC telemetry frameworks for centralized fleet monitoring.

Ideal for

• Converged SAN and LAN consolidation in HPE ProLiant and Dell PowerEdge rack servers, replacing separate FC HBAs and Ethernet NICs with a single quad-port 100GbE CNA
• NVMe over Fabrics (NVMe-oF) host connectivity for all-flash storage arrays requiring sub-10µs latency and sustained 400Gbps aggregate host bandwidth
• Large-scale VMware vSphere or Red Hat OpenShift virtualization clusters requiring hardware-accelerated iSCSI multipath I/O and RoCEv2 for vMotion and storage vMotion optimization
• High-frequency financial trading and algorithmic workloads leveraging RoCEv2 RDMA for kernel-bypass, low-latency inter-node messaging across converged 100GbE spine-leaf fabrics
• AI and machine learning training clusters utilizing GPUDirect RDMA over RoCEv2 for GPU-to-GPU collective communications without CPU involvement
• Multi-tenant cloud service provider environments running FCoE storage access and tenant overlay networks (VXLAN/NVGRE) simultaneously across a single consolidated 100GbE infrastructure
