Best for

Datacenter InfiniBand fabrics
Use this HPE InfiniBand EDR 100Gb 1-port 841QSFP28 adapter in datacenter environments that standardize on EDR 100Gb InfiniBand and QSFP28 interconnects for server-to-switch or node-to-node links.
High performance computing clusters
Deploy the Mellanox ConnectX-5 based EDR 100Gb 1-port 841QSFP28 adapter in HPC clusters that require a dedicated InfiniBand host channel adapter to integrate nodes into an EDR 100Gb fabric.
Single-port EDR connectivity
Ideal for systems needing a focused, single-port InfiniBand EDR 100Gb interface using QSFP28, where one high-bandwidth link is sufficient for the workload or network design.
QSFP28-based infrastructure
Suitable for infrastructures built around QSFP28 cabling, this adapter provides 1-port EDR 100Gb InfiniBand connectivity aligned with existing QSFP28 hardware in the environment.
Datacenter expansion projects
Useful in datacenter expansion projects that add incremental EDR 100Gb InfiniBand capacity on a per-port basis, using a 1-port QSFP28 adapter to scale gradually.

Frequently asked questions

What type of network connectivity does the HPE P23828-001 adapter provide?

The HPE P23828-001 is an InfiniBand host channel adapter that provides EDR 100Gb InfiniBand connectivity. It is specified as an InfiniBand EDR 100Gb 1-Port 841QSFP28 Adapter, making it suitable for environments that rely on EDR 100Gb InfiniBand fabrics rather than Ethernet connectivity.
