About the HPE 700759-B21 - HPE FlexFabric 10Gb 2-port 533FLR-T Adapter
Advanced offload capabilities including TCP Segmentation Offload (TSO), Large Receive Offload (LRO), checksum offload, and Receive Side Scaling (RSS) make the HPE 700759-B21 a high-performance solution for demanding datacenter environments. This HPE FlexFabric 10Gb 2-port 533FLR-T Adapter delivers dual 10 Gigabit Ethernet connectivity in a compact FlexibleLOM form factor, enabling network engineers and infrastructure teams to maximize throughput while minimizing CPU overhead. The adapter's intelligent offloading architecture reduces processor load during high-volume data transfers, making it ideal for virtualized workloads, cloud deployments, and storage-intensive applications.
Built on the Intel X540 controller and interfacing via PCIe 2.0 x8 through the FlexibleLOM slot, the 700759-B21 integrates seamlessly into HPE ProLiant Gen8 and Gen9 servers. Full-duplex operation with IEEE 802.3x flow control ensures reliable, bidirectional communication, while support for jumbo frames up to 9,000 bytes (9K MTU) optimizes performance for large data transfers. VLAN tag insertion and stripping comply with IEEE 802.1Q standards, providing enterprise-grade network segmentation. The adapter supports Cat6a cabling up to 55 meters and Cat7 up to 100 meters, offering flexible deployment options across modern datacenters. Operating across Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi, the adapter maintains broad OS compatibility. HPE OneView, HPE Intelligent Provisioning, HPE Smart Update Manager (SUM), and iLO integration streamline deployment and lifecycle management for IT procurement teams. Certified to CE, FCC Class A, and RoHS standards, the 700759-B21 meets strict regulatory requirements for global operations.
