HPE 779799-B21

10 Gb 2-Port 546FLR-SFP+ Gigabit Ethernet Adapter

The HPE 779799-B21 Gigabit Ethernet Adapter10 Gb 2-Port 546FLR-SFP+ Gigabit Ethernet Adapteris a high-performance FlexibleLOM network cardengineered to deliver exceptional bandwidth, low latency, and advanced virtualization support for HPE ProLiant servers. Featuring dual 10 Gb SFP+ ports, it offers up to 40 Gb/s aggregate bi-directional throughput, ideal for I/O-intensive workloads such as virtualization, database applications, and block storage. Powered by a Mellanox ConnectX-3 ASIC with 128 MB onboard memory, this Gigabit Ethernet Adaptersupports RDMA over Converged Ethernet (RoCE), overlay tunneling (e.g., VXLAN, NVGRE), jumbo frames, VLAN, QoS, and SR-IOV for maximized VM density and efficiency. The FLR (FlexLOM) form factor enables seamless integration into Gen9 ProLiant servers—making it a versatile solution for scale-out and cloud-defined data centers seeking optimized connectivity and performance. 

Features

The 546FLR-SFP+ Gigabit Ethernet Adaptersignificantly enhances network throughput and virtualization efficiency. Each port supports 20 Gb/s bi-directional transfer, delivering up to 40 Gb/s total bandwidth to alleviate network bottlenecks and accelerate application performance. The Mellanox ConnectX-3 processor offloads intensive networking tasks—including RoCE, overlay tunneling, and storage protocols—reducing CPU overhead and improving VM density. With features like receive-side scaling (RSS), SR-IOV, and support for jumbo frames, it delivers high throughput while maintaining low CPU utilization and latency. FlexibleLOM integration ensures this Gigabit Ethernet Adapterfits seamlessly into ProLiant Gen9 rack servers such as DL360, DL380, DL560, and others. It’s backward-compatible with PCIe 3.0 x8 or x4 slots and supports both UEFI and legacy boot. Management and diagnostics tools support teaming, PXE boot, and remote diagnostics. Whether for virtualized environments, high-speed storage access, or scale-out clusters, this adapter is a powerful, future-ready network interface with enterprise-grade reliability. 

Advanced Options

Built for enterprise-class reliability, the HPE 779799-B21 Gigabit Ethernet Adapterensures consistent, high-throughput network performance under demanding workloads. Its offload capabilities—such as RoCE and overlay tunneling—minimize CPU utilization, allowing host systems to support a higher VM density with lower latency. The onboard ConnectX-3 ASIC accelerates critical networking functions, from RDMA to VLAN and QoS handling.
