PCIe 2.0 x8 electrical connectivity sets the host interface ceiling for this HPE FlexFabric 10Gb 2-port 534FLR-SFP+ Adapter, delivering the bandwidth required for dual 10 Gbps ports while maintaining compatibility with enterprise-grade server infrastructure. The FlexibleLOM form factor eliminates dedicated expansion slots, enabling network density without hardware footprint compromise—a critical advantage for network engineers and IT procurement teams architecting high-speed fabric deployments across virtualized environments.
HPE's 700751-B21 adapter leverages the Emulex XE201 controller to enable intelligent offload operations including TCP Segmentation Offload, Large Receive Offload, and IPv4/IPv6 checksum acceleration. SR-IOV support empowers virtual machine workloads with direct access to port resources, reducing latency and CPU overhead in consolidated environments. The adapter's dual SFP+ ports support 10GBase-SR, 10GBase-LR, and 10GBase-CR protocols, accommodating short-reach, long-haul, and direct-attach copper deployments. Native integration with HPE iLO, Insight Diagnostics, and OneView streamlines provisioning, monitoring, and lifecycle management across HPE ProLiant Gen8 and Gen9 server families (DL360, DL380, DL560, DL580 FlexibleLOM-equipped models). Operating system support spans Windows Server 2008 R2, 2012, and 2012 R2; Red Hat Enterprise Linux; SUSE Linux Enterprise Server; and VMware ESXi. RoHS, CE, and FCC certifications confirm regulatory alignment for global deployments.
