This HPE 535T 10Gb 2-port BASE-T adapter leverages advanced offload capabilities including TCP Segmentation Offload (TSO), Large Receive Offload (LRO), IPv4/IPv6 checksum offload, and VLAN tag insertion/stripping to reduce CPU overhead and maximize application throughput. The adapter is built around the Broadcom BCM57416 controller and connects via PCIe Gen3 x8, delivering dual 10GBASE-T ports with auto-negotiating support for 1000BASE-T backward compatibility. Compliant with IEEE 802.3an standards, this low-profile adapter supports Cat6a cabling up to 55 m at 10GbE speeds and Cat7 cabling up to 100 m, making it flexible for diverse data center and enterprise network topologies. The HPE 813661-B21 includes a low-profile bracket and integrates seamlessly with HPE iLO and HPE OneView management platforms.
Network engineers and IT infrastructure teams standardizing on HPE environments choose this adapter for its broad virtualization support, including SR-IOV capability for virtual machine isolation and resource optimization. The HPE 535T is validated for HPE ProLiant Gen9 and Gen10 rack and tower servers, eliminating qualification risk. Multi-OS support—Microsoft Windows Server 2012 R2, 2016, and 2019; Red Hat Enterprise Linux; SUSE Linux Enterprise Server; and VMware ESXi—ensures compatibility across heterogeneous workloads. Organizations deploying high-performance storage, backup, or virtual infrastructure benefit from the combined effects of hardware offloading and proven compatibility, reducing latency-sensitive bottlenecks without additional software tuning.
The HPE 813661-B21 meets CE, FCC, and RoHS regulatory requirements, assuring compliance in global supply chains. Whether you're planning a refresh cycle or scaling network capacity, Omnixon Global can support your procurement with detailed technical validation and competitive sourcing.
