Description

Dual-port 100Gb VPI adapter enabling HDR100 InfiniBand or 100GbE across two QSFP56 interfaces for redundant, multi-fabric, or aggregated designs. PCIe 4.0 x16 connectivity with deep offloads (RDMA, OVS/ASAP2, NVMe-oF) delivers low-latency performance for clustered compute and storage nodes. Purpose-built for scalable HPE ProLiant environments.

Features

- Dual 100G ports for redundancy or multi-fabric connectivity
- VPI versatility for HDR100 InfiniBand and 100GbE
- PCIe 4.0 x16 host interface for high aggregate throughput
- Comprehensive RDMA and virtualization offloads
- Ideal for clustered compute and NVMe-oF storage nodes

FAQs

Q: Can one port run InfiniBand and the other Ethernet?
A: Yes. Each port can be independently configured for Ethernet or InfiniBand.

Q: Is link aggregation supported on Ethernet?
A: Yes, standard LAG/LACP can be used on Ethernet networks where supported by the OS and switches.

Q: What is the recommended PCIe slot?
A: Use a PCIe Gen4 x16 slot to provide sufficient bandwidth for two 100G ports.

Q: Does it support virtualization offloads?
A: Yes, SR-IOV and advanced overlay offloads (e.g., VXLAN/GENEVE) are supported.

Q: Are QSFP28 optics supported?
A: Yes, QSFP28 modules/DACs are supported at compatible lower speeds.
