Green single-port QSFP28 NIC with full-height bracket

SMUGDESK

SMUGDESK PCIe3.0 x16 QSFP28 100G NIC ConnectX-5

SKU CH-RS04-P36DP

100 Gbps single-port QSFP28 NIC with PCIe 3.0 x16, SR-IOV, RoCE v2 and TCP/UDP offload for H3C server replacement

  • 100 Gbps throughput via PCIe 3.0 x16 and single QSFP28 port
  • Direct drop-in replacement for H3C BC51B and BC51BMA part numbers
  • SR-IOV and RoCE v2 offload reduce CPU load in virtualised clusters
  • Jumbo frames up to 9000 MTU plus VLAN and PXE boot support
  • Full-height and low-profile brackets fit standard and dense H3C rack servers

Direct H3C BC51BMA Replacement

The SMUGDESK PCIe3.0 x16 NIC is a single-port QSFP28 100GbE adapter built as a drop-in substitute for H3C BC51B and BC51BMA part numbers 02312BFF and 2102312BFF. It targets data-centre operators and HPC clusters that need a direct swap without firmware or driver changes.

Standard Server Thermal Envelope

The card uses a PCIe 3.0 x16 interface and the Mellanox ConnectX-5 controller, drawing power within typical server-slot limits. Passive heatsink cooling relies on chassis airflow, so acoustic output matches the host system fan curve rather than adding its own noise.

Full and Low-Profile Brackets Included

Both bracket heights ship in the box, allowing installation in 1U racks or full-height chassis without extra parts. Driver support spans Windows Server, Linux and VMware ESXi, enabling SR-IOV virtualization, RoCE v2 and TCP/UDP offload for NVMe over Fabrics deployments.

Questions about this item

How do I install the SMUGDESK PCIe3.0 x16 QSFP28 100G NIC and what step is often missed?

Insert the card into a PCIe 3.0 x16 slot, secure the correct full-height or low-profile bracket, then attach a QSFP28 module; the step often missed is enabling SR-IOV and RoCE v2 in the system BIOS and driver for virtualization offload.

What maintenance or replacement will the SMUGDESK ConnectX-5 100G NIC need later?

The card itself has no moving parts; plan to replace QSFP28 optical or DAC copper modules if links degrade, and keep driver firmware current for Windows Server, Linux, or VMware ESXi compatibility.

What limit appears first on the SMUGDESK PCIe3.0 x16 100G NIC under sustained load?

The PCIe 3.0 x16 bus caps theoretical throughput near 100Gbps, so sustained line-rate traffic hits the bus ceiling before the ConnectX-5 engine or 9000 MTU jumbo frame handling becomes a bottleneck.
