HPE InfiniBand 100Gb PCIe 3.0 x16 QSFP28 Single-Port Network Adapter 825110-B21

SKU CH-RRMF-92A5T

A 100 Gbps InfiniBand adapter with a single QSFP28 port on a PCIe 3.0 x16 interface

  • Speed100Gbps
  • InterfacePCI-Express
  • 100 Gbps throughput for data-intensive workloads
  • PCIe 3.0 x16 interface delivers full bandwidth
  • Single QSFP28 port supports InfiniBand EDR
  • Low-latency connectivity for HPC clusters
  • Part number 825110-B21 for exact identification

HPE InfiniBand 100Gb QSFP28 Adapter

This HPE network adapter delivers 100 Gbps connectivity through a single QSFP28 port. It installs in a PCI Express 3.0 x16 slot and supports InfiniBand EDR plus 100 Gigabit Ethernet protocols. The card targets high-performance computing clusters and data-intensive workloads that require low-latency, high-throughput fabric links.

Suited for HPE server integration

The adapter fits HPE server platforms that provide a PCIe 3.0 x16 slot and a compatible QSFP28 cage. It serves workloads needing a single 100 Gbps fabric connection. Sites requiring dual-port redundancy, a different slot width, or an alternative form factor should evaluate other options.

PCIe 3.0 x16 slot requirement

The card occupies a full-length PCI Express 3.0 x16 slot, so the host system must expose that physical and electrical interface. Verify the server riser and chassis clearance before purchase. Without an available x16 lane group the adapter cannot operate at its rated 100 Gbps speed.

Questions about this item

How can I verify the adapter is running at 100 Gbps after installation?

Check the link status in the OS network utility or HPE iLO; it should show a 100 Gbps InfiniBand EDR or 100 Gigabit Ethernet connection on the QSFP28 port.

What ships with the 825110-B21 and what must I source separately?

The box contains the single-port PCIe 3.0 x16 adapter; you must purchase a compatible QSFP28 transceiver or direct-attach cable separately.

Which version of this adapter should I choose for an HPE server needing one 100 Gbps InfiniBand link?

The 825110-B21 is the single-port 100 Gbps PCIe 3.0 x16 QSFP28 model; select it when only one InfiniBand EDR or 100 GbE connection is required.
