HPE P23832-001
InfiniBand EDR / 100 GbE 1‑Port 840QSFP28 Network Adapter
The HPE P23832‑001 is a single-port Network Adapter using a QSFP28 interface to deliver 100 Gb/sec bandwidth in either InfiniBand EDR or Ethernet mode. Based on Mellanox ConnectX‑5 technology, this compact PCIe card is ideal for high-performance computing, storage fabrics, or cloud deployments. It offers flexible deployment in both RDMA‑optimized InfiniBand fabrics and 100 Gb Ethernet networks, making it ideal for modern enterprise, HPC, or AI/ML workloads requiring ultra-low latency and high throughput.
Features
This Adapter installs into a PCI Express 3.0 ×16 slot and supports both InfiniBand EDR and 100 Gigabit Ethernet—controlled via firmware mode switching. With a single QSFP28 port that accepts DAC or AOC cables, it offers full line-rate performance in both protocol types. Certified on HPE ProLiant Gen9/Gen10 and Apollo server series, it supports advanced features such as RDMA (RoCE), SR‑IOV, VXLAN, and TCP/IP offloads for minimized CPU usage. Optimized for clustered computing and storage fabrics, the Adapterdelivers predictable low-latency performance across diverse environments. ([turn0search0]turn0search15turn0search12)
Advanced Options
Engineered for environments demanding consistent 100 Gb throughput and ultra-low latency, this Adapter supports microsecond-level RTT in InfiniBand EDR and line-rate performance in Ethernet mode. Its robust QSFP28 design sustains minimal jitter even under high-load workloads.
