HPE InfiniBand EDR/Ethernet 100Gb 2-Port 841QSFP28 Adapter
872726-B21 · Refurbished · 1 year warranty
Quantity (units)
Overview
HPE 872726-B21 is a dual-protocol adapter. Its two QSFP28 ports run either 100Gb EDR InfiniBand or 100GbE Ethernet, so the same card can serve an HPC cluster fabric or a high-speed Ethernet network.
InfiniBand EDR is a common interconnect in compute clusters where low latency between nodes matters. On the Ethernet side, 100GbE ports suit storage nodes and hosts that move large datasets. Two ports per card give either a redundant connection or two separate fabrics.
QSFP28 cages take 100Gb optics or direct-attach cables. Match the cable or optic type to the protocol you plan to run.
The HPE spare number for the 841QSFP28 is 878579-001.
Available conditions are Refurbished and Used. Refurbished cards include 1 year or 3 years of warranty, Used cards include 90 days. Tell us whether you plan to run InfiniBand or Ethernet, plus the quantity, and we will reply with pricing.
