Detailed Specifications
HPE 764302-B21 FlexFabric 536FLR-T 4-Port 10GbE Adapter
Overview
The HPE 764302-B21 is a quad-port 10 Gigabit Ethernet adapter in a FlexibleLOM/FLR-T form factor designed for installation in supported HPE ProLiant Gen9 and Gen10 servers. It provides four independent 10 Gb/s RJ-45 BASE-T ports leveraging existing copper cabling for high-bandwidth uplinks, making it ideal for virtualised environments, storage traffic and converged infrastructure. With full line-rate throughput across all ports and advanced offloads (such as SR-IOV, VXLAN/NVGRE tunnelling, DCB), it enables optimized server network I/O and consolidation of multiple network functions. The adapter fits mezzanine/FLR slots thereby freeing standard PCIe slots, which is valuable in dense rack or blade server deployments.
