High-Performance Server Network Adapters

Server network adapters, or Network Interface Cards (NICs), are specialized expansion cards that enable a server to connect to a network. The category of 10 Gigabit Ethernet (10GbE) adapters represents the mainstream standard for enterprise and data center server connectivity, balancing cost, performance, and power consumption. Unlike consumer-grade network cards, server adapters like the HPE 817719-001 are built for durability, manageability, and continuous operation under heavy loads.

Key Characteristics of Enterprise Server Adapters

This category is defined by several non-negotiable attributes: hardware reliability for 24/7 uptime, advanced features like TCP/IP offload engines (TOE) and RDMA support for reducing CPU overhead, and deep integration with server management suites (like HPE iLO). The HPE 535FLR-T adapter exemplifies these traits, providing not just raw speed but intelligent networking that optimizes overall server performance.

Form Factor and Physical Interface

The "FLR-T" designation indicates this is a FlexLOM Ready adapter in a "Tall" bracket form factor. This design is tailored for HPE server chassis, ensuring proper fit and airflow. The card utilizes a PCI Express 3.0 x8 host interface, providing ample bandwidth (up to 7.88 GB/s each direction) to handle the aggregate 20 Gbps of its two ports without becoming a bottleneck.

PCIe 3.0 x8: The Bandwidth Backbone

The choice of PCIe 3.0 x8 is strategic. It offers double the per-lane bandwidth of PCIe 2.0, ensuring that the adapter can sustain full duplex traffic on both 10G ports simultaneously. This future-proofs the card against evolving network demands and multi-application workloads.

Storage Networking and SAN

With its support for iSCSI and FCoE offload, this NIC is ideal for connecting servers to IP-based or converged storage area networks (SANs). It provides the high throughput needed for data-intensive tasks like virtualization, database workloads, and large file transfers. In HCI deployments where compute and storage are combined, the low latency and high bandwidth of this 10GbE adapter are critical for node-to-node communication and access to virtual SANs.

HPE ProLiant Server Ecosystem

A key advantage of the 817719-001 is its seamless integration into the HPE ecosystem, offering benefits beyond pure hardware specifications. For technical computing, rendering farms, or scientific clusters, the adapter’s Ro CE capability facilitates rapid data exchange between nodes, significantly reducing processing times for parallelized tasks.

Firmware

The adapter is fully discoverable and manageable through HPE 817719-001 Integrated Lights-Out (iLO) management. It works in concert with HPE Systems Insight Manager (SIM) and HPE One View for unified infrastructure management. Firmware updates are delivered through HPE Service Pack for ProLiant (SPP), ensuring compatibility and stability. Ensure the server BIOS is configured to give the PCIe slot adequate bandwidth and latency priority. For the best performance, install the adapter in a true x8 or wider slot. Utilizing the latest HPE-provided drivers, which are optimized for the adapter's offload engines, is non-negotiable for achieving rated performance.

Network Switch Alignment

The connected switch ports must be configured to match the adapter's settings. Enable features like Jumbo Frames (MTU 9000) end-to-end, ensure flow control settings are aligned, and verify that link aggregation (if using LACP) is configured identically on both the switch and the server operating system. In hypervisors like VMware vSphere or Microsoft Hyper-V, ensure that the virtual switch is configured to leverage the NIC's advanced capabilities. Enable SR-IOV for near-bare-metal performance for critical VMs, or correctly configure VMQ/VMDq settings to distribute network processing efficiently across CPU cores.

Vs. HPE 534FLR-T (1GbE) and 561FLR-T (1GbE Base-T)

The 535FLR-T provides a 10x bandwidth increase over 1GbE adapters, essential for modern application workloads, storage, and virtualization. It moves the network from a potential bottleneck to an enabling asset.

Vs. HPE 561T (10G Base-T) and 562SFP+ (10G SFP+) Adapters

The 561T uses RJ45 ports for 10GBASE-T copper, ideal for Cat6a/Cat7 cabling but typically with higher power and latency. The 562SFP+ is a similar 2-port SFP+ card but may be based on a different controller. The 535FLR-T is often optimized for specific HPE server generations and may offer better power efficiency and integration.

Vs. HPE 640FLR-SFP28 (25GbE) and Higher-Speed Adapters

While 25GbE, 40GbE, and 100GbE adapters offer more bandwidth, they come at a higher cost and require more advanced switching infrastructure. The 10GbE offered by the 535FLR-T remains the "sweet spot" for most general enterprise and mid-range data center applications, balancing performance with total cost of ownership.

Data Center Server Connectivity

As a primary or secondary network interface in rack and blade servers, this adapter connects servers to top-of-rack (ToR) 10GbE switches, forming the core of a modern, flat network architecture. It eliminates the oversubscription and cabling complexity associated with aggregating multiple 1GbE links.

Compatibility

The adapter features two 817719-001 SFP+ (Enhanced Small Form-Factor Pluggable) cages. These support a wide range of 10GbE optical (e.g., SFP+ SR, LR) or direct-attach copper (DAC) transceivers, offering unparalleled media flexibility. At the heart of the 535FLR-T adapter is a sophisticated Ethernet controller. This chipset enables critical enterprise features.
