The HPE P21933-B21 network adapter operates on PCIe Gen 3 x8, delivering the host interface bandwidth and compatibility required for demanding enterprise workloads. This low-profile adapter combines four 10Gbps SFP+ ports into a single, unified I/O solution with aggregate bandwidth of 40Gbps, making it ideal for network engineers and infrastructure teams seeking to consolidate high-speed connectivity without sacrificing performance or physical space constraints.
Built on the Marvell FastLinQ QL41134HLCU controller, the P21933-B21 supports a comprehensive protocol stack including Ethernet, iSCSI, FCoE, and RoCE, alongside advanced offload engines for TCP/IP, LSO, LRO, RSS, and additional iSCSI and FCoE acceleration. HPE's implementation includes SR-IOV virtualization support for environments requiring granular resource isolation, 802.1Q VLAN tagging, and jumbo frame capability up to 9600 bytes MTU. The adapter ships with both low-profile and full-height brackets, ensuring deployment flexibility across HPE ProLiant Gen10 and Gen10 Plus servers. Integrated management via HPE iLO, Smart Update Manager (SUM), and Intelligent Provisioning streamlines configuration and firmware updates across mixed-OS environments—Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi. Standards compliance with IEEE 802.3ae, 802.1Q, and 802.3x ensures interoperability with industry-standard network infrastructure and storage systems.
