HPE P21112-B21 INT E810 100GbE 2P QSFP28 Adptr
Overview
The HPE P21112-B21 is an Intel E810-based dual-port 100GbE network adapter designed for servers requiring high-bandwidth, low-latency connectivity. This adapter is critical for environments where large volumes of data, such as high-resolution video streams from multiple surveillance cameras or large datasets from storage arrays, need to be processed and transferred rapidly. It enables direct server integration into 100 Gigabit Ethernet networks, bypassing potential bottlenecks in lower-speed infrastructure.
Compatibility
This adapter is designed for HPE ProLiant DL/ML/Apollo servers and other systems supporting PCIe Gen4 x16 slots. It is compatible with network infrastructure utilizing QSFP28 transceivers and 100GbE switches. Specific server models include HPE ProLiant DL380 Gen10 Plus, DL360 Gen10 Plus, and Apollo 4510 Gen10 Plus, among others. Always verify PCIe slot availability and physical clearance within your specific server chassis.
Installation Notes
Installation requires opening the server chassis and seating the adapter into a PCIe Gen4 x16 slot. Ensure the server is powered off and properly grounded before installation. The adapter utilizes QSFP28 transceivers (sold separately) which must be compatible with your network switches. Driver installation for the Intel E810 chipset will be necessary on the host operating system.
