HPE 700759-B21 FlexFabric 10Gb 2-Port 533FLR-T Network Adapter

Overview

The HPE 700759-B21 is a high-performance dual-port 10-Gigabit Ethernet network adapter designed to deliver exceptional throughput, low latency, and efficient data flow in enterprise server environments. Built as part of the HPE FlexFabric family, this adapter provides advanced networking and storage convergence, helping businesses streamline data center operations while maintaining top-tier performance. With its advanced design, the HPE 700759-B21 integrates perfectly into HPE ProLiant Gen9 and Gen10 servers, offering reliability, scalability, and optimal use of server resources.

This adapter uses the FlexibleLOM (FLR-T) interface, allowing servers to achieve high connectivity without occupying standard PCIe expansion slots. It supports a wide range of modern networking technologies including network partitioning, virtualization acceleration, and offload capabilities, all tailored to handle today’s data-intensive workloads.

High-Speed Connectivity and Performance

The HPE 700759-B21 provides two RJ-45 ports, each capable of delivering up to 10GbE speeds, resulting in a combined throughput of up to 20 Gbps. This ensures fast and stable data transmission, ideal for demanding enterprise applications such as virtualization, data storage, and cloud computing. The adapter supports full-duplex operation on both ports, reducing latency and ensuring consistent network performance even under heavy workloads.

The card connects through the PCIe 2.0 x8 interface, maximizing communication efficiency between the network controller and the server motherboard. Its optimized architecture enables line-rate performance across both ports while reducing CPU utilization through hardware-based packet handling and advanced offload features.

Advanced Features and Functionality

The HPE 700759-B21 is equipped with an array of advanced features that enhance network performance and simplify data center management. It supports TCP/IP checksum offloading, large send and receive offload, VLAN tagging, jumbo frames, and Receive Side Scaling (RSS). These capabilities reduce the processing burden on the host CPU, allowing applications to run more efficiently.

One of its standout features is Single Root I/O Virtualization (SR-IOV), which enables multiple virtual machines to share a single physical network adapter while maintaining high performance and low latency. This makes the adapter ideal for virtualized server environments running VMware, Microsoft Hyper-V, or Linux KVM platforms.

In addition, Network Partitioning (NPAR) allows the physical adapter to be divided into multiple logical network interfaces. Each partition can be assigned specific bandwidth allocations and traffic priorities, making it easier to isolate different workloads such as management, storage, and production traffic.

FlexFabric and Converged Networking

As part of the FlexFabric technology line, the HPE 700759-B21 supports converged networking, combining both Ethernet and storage data traffic on a single adapter. This helps businesses simplify their cabling infrastructure, reduce hardware costs, and enhance scalability. By integrating storage protocols like iSCSI and FCoE over Ethernet, the adapter minimizes the need for separate network and storage adapters, leading to reduced power consumption and simplified network management.

Virtualization Optimization

The adapter is fully optimized for modern virtualized environments. Its support for SR-IOV, Virtual Machine Queue (VMQ), and other virtualization technologies ensures that network traffic is efficiently distributed among virtual machines without causing CPU bottlenecks. This leads to higher application performance, improved scalability, and better isolation between workloads running on the same host server.

Reliability and Compatibility

The 700759-B21 is engineered for long-term reliability in mission-critical enterprise environments. It integrates seamlessly with HPE’s ProLiant DL and ML series servers and is fully compatible with HPE management tools and utilities such as iLO and Insight Control. This integration ensures simplified configuration, monitoring, and firmware updates, providing IT administrators with unified control over networking and system performance.

Its robust design and HPE’s stringent quality assurance process make it suitable for data centers, cloud infrastructure, and enterprise networks requiring continuous uptime and dependable performance.

Efficiency and Cost Savings

By combining multiple networking functions into one compact and efficient card, the HPE 700759-B21 reduces cabling complexity and hardware requirements. The adapter’s energy-efficient design and offload capabilities help lower power consumption, cooling demands, and overall operational costs. These advantages make it an ideal choice for organizations looking to optimize performance while maintaining sustainable and cost-effective IT operations.
