HP HSTNS-B017 56Gb/s FDR Dual-Port FlexibleLOM QSFP Adapter, HP P/N 705088-001 / 702212-B2: This is a FlexibleLOM (FlexLOM) network adapter for HP ProLiant Gen8 and Gen9 servers, providing two QSFP ports for InfiniBand FDR (56Gb/s) or Ethernet operation. The card uses a Mellanox ConnectX-3 Pro controller and connects to the host via a PCIe 3.0 x8 lane interface routed through the FlexLOM slot, which is distinct from a standard PCIe expansion adapter and frees the standard PCIe slots for other I/O. This is a refurbished unit.
Engineering Context
The 545FLR-QSFP card targets InfiniBand FDR fabrics with a per-port line rate of 56 Gb/s, while also supporting Ethernet operation on the same QSFP ports for converged deployments. The PCIe 3.0 x8 host link provides approximately 63 Gbps of usable bandwidth, sufficient to feed a single FDR port at full rate but not both ports simultaneously at line rate. Mellanox ConnectX-3 Pro silicon supports RDMA, RoCE, and stateless TCP offloads, reducing CPU overhead during high-throughput transfers.
Deployment & Use Cases
HPC compute clusters running MPI workloads on HP ProLiant DL360 Gen8/Gen9 and DL380 Gen8/Gen9 nodes. Storage fabric interconnect for scale-out file systems such as Lustre, GPFS/Spectrum Scale, and BeeGFS. RDMA-accelerated database back-ends and shared-storage clusters where in-band FDR connectivity is preferred over iSCSI or FCoE.

Compatibility & Hard Constraints
Designed for HP ProLiant servers equipped with a FlexibleLOM slot (DL360 Gen8/Gen9, DL380 Gen8/Gen9 and similar). Not a standard PCIe expansion adapter — it will not seat in a regular PCIe slot. Each unit ships as a stand-alone card, not paired with FDR cables; QSFP cables and switches must be sourced separately. Verify the HP server iLO and BIOS revisions support this FlexLOM card before deployment.
