HPE 766490-B21

FlexFabric 10 Gb 2-Port 536FLB Gigabit Ethernet Adapter

The HPE 766490-B21 FlexFabric 10 Gb 2-Port 536FLB Gigabit Ethernet Adapter(Spare Part 768080-001) is a high-performance FlexibleLOM network Gigabit Ethernet Adapterdesigned for HPE ProLiant Gen9 blade servers. It delivers dual 10 Gb Ethernet connectivity in a compact form factor, optimized for converged networking Gigabit Ethernet Adapter. This adapter is ideal for virtualized data centers, cloud infrastructure, and high-throughput workloads, offering robust support for FCoE and iSCSI traffic, hardware offload features, and bandwidth partitioning. Whether you're consolidating network traffic or deploying multi-tenant architectures, the 536FLB delivers versatility and efficiency without sacrificing network performance.

Features

Engineered for HPE ProLiant BL460c Gen9, BL660c Gen9, WS660c Gen9 blades, and select Gen10 variants, the 536FLB Gigabit Ethernet Adapterinstalls in a FlexibleLOM slot, preserving full-length PCIe lanes for additional I/O expansions . Utilizing a Cavium 57840S single-chip solution, the Gigabit Ethernet Adapterdelivers exceptional performance and energy efficiency, offering full-duplex 10 Gb links with a combined theoretical bandwidth of up to 40 Gb/s per Gigabit Ethernet AdapterDesigned for modern converged infrastructures, it supports Flex-10 and FlexFabric technologies—allowing each physical port to be subdivided into up to four FlexNICs for granular bandwidth management in virtual environments . The Gigabit Ethernet Adapterincludes hardware offloads like FCoE, iSCSI, PXE boot, VLAN tagging, Jumbo Frames, NIC teaming, MSI-X, Receive-Side Scaling (RSS), and tunnel offloads for NVGRE/VXLAN—helping reduce CPU load and improve throughput.

Advanced Options

Additional enterprise features—such as adaptive interrupt coalescing, DPDK support, TCP/UDP checksum and segmentation offloads, IPv6 acceleration, and precision time protocol (IEEE 1588 PTP)—further enhance network performance and flexibility The HPE 536FLB Gigabit Ethernet Adapterprovides enterprise-grade reliability and performance. With a robust FlexibleLOM design, it ensures secure, low-latency network connectivity while preserving system expansion capabilities. Its dual-port architecture and full-duplex 10 Gb/s bandwidth per port deliver ample throughput (up to 40 Gb/s aggregate) for storage, virtualization, and high-density networking workloads.
