About the HPE P21112-B21 - Intel E810-CQDA2 Ethernet 100Gb 2-port QSFP28 Adapter for HPE

Advanced offload capabilities including RDMA support for RoCEv2 and iWARP, IEEE 1588 PTPv2 hardware timestamping, checksum offload, RSS, LSO, and LRO enable the HPE P21112-B21 to deliver exceptional performance in latency-sensitive and throughput-demanding environments. This Intel E810-CQDA2 based adapter brings 200 Gbps aggregate throughput to HPE ProLiant and Apollo infrastructure through its dual QSFP28 ports operating at 100 Gigabit Ethernet per port. Network engineers and infrastructure architects will appreciate the 256 virtual functions per port via SR-IOV, VXLAN and GENEVE tunnel offload capabilities, and Dynamic Device Personalization support for runtime pipeline reconfiguration of custom protocol profiles.

The HPE P21112-B21 arrives in a low-profile PCIe form factor, fitting HPE ProLiant Gen10 and Gen10 Plus servers alongside HPE Apollo systems via its PCIe 4.0 x16 host interface. Supported Ethernet standards include 100GBASE-CR4, 100GBASE-SR4, and 100GBASE-LR4, providing flexibility across copper and optical deployment scenarios. Native integration with HPE iLO and HPE OneView ensures seamless firmware and health lifecycle management. The adapter supports Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi operating systems, making it suitable for virtualized, containerized, and bare-metal workloads across hybrid cloud environments.

Typical Enterprise Deployment Scenarios

  • High-frequency trading and financial services platforms requiring sub-microsecond latency via hardware timestamping and RDMA acceleration
  • AI and machine learning clusters leveraging RoCEv2 for GPU interconnect and distributed training at scale
  • Cloud data centers and service providers consolidating virtual network functions through advanced SR-IOV segmentation
  • Storage area networks and converged infrastructure benefiting from tunnel offload and adaptive segmentation protocols
  • Mission-critical applications in virtualized environments using VMware ESXi with offloaded checksum and segmentation
