Frequently Asked Questions
What servers are compatible with the HPE 561FLR-T FlexibleLOM adapter? +
The HPE 561FLR-T is specifically designed for select HPE ProLiant Gen8 and Gen9 rack and blade servers. It utilizes the FlexibleLOM form factor, which allows for dedicated slot integration without consuming standard PCIe expansion slots. We recommend verifying your specific server model’s quickspecs to ensure mechanical and firmware compatibility before installation.
Does the HPE 561FLR-T support 10GBASE-T copper cabling? +
Yes, this adapter features two 10GbE RJ45 ports that support standard 10GBASE-T copper cabling. This makes it an ideal choice for data centers that prefer Cat6a or Cat7 copper infrastructure over fiber optics, as it provides high-performance connectivity while maintaining compatibility with traditional RJ45 networking equipment and switches.
How does the HPE 561FLR-T impact server CPU overhead? +
This adapter offloads packet processing tasks from the server CPU to the network card. By utilizing advanced features like TCP Offload Engine (TOE), Receive Side Scaling (RSS), and Large Send Offload (LSO), it significantly reduces CPU utilization. This ensures your server’s processing power remains dedicated to your primary applications rather than managing network traffic.
Can I use the HPE 561FLR-T in a virtualized environment? +
Absolutely. The 561FLR-T is fully compatible with virtualization technologies, including support for SR-IOV (Single Root I/O Virtualization). This allows the adapter to present multiple virtual functions to the hypervisor, enabling direct hardware access for virtual machines. This improves throughput and reduces latency in demanding VMware or Hyper-V deployments.
What is the primary benefit of the FlexibleLOM form factor compared to PCIe cards? +
The FlexibleLOM design offers a dedicated, localized connection to the server motherboard, saving valuable PCIe slots for other add-in cards like GPUs or RAID controllers. Because it connects directly to the system board, it integrates seamlessly with the server’s onboard management tools, providing a cleaner physical installation and more efficient internal airflow.
Is the HPE 561FLR-T capable of auto-negotiating lower speeds? +
The 10GBASE-T ports on the 561FLR-T are designed to be backward compatible with standard networking speeds. It can auto-negotiate between 10Gbps, 1Gbps, and 100Mbps, depending on the switch infrastructure and cabling quality in your environment. This flexibility allows the card to function in mixed-speed data center environments without requiring immediate upgrades to all existing switch hardware.
What operating systems are supported by the HPE 561FLR-T? +
The 561FLR-T is designed to integrate with all major enterprise operating systems, including various distributions of Windows Server, Red Hat Enterprise Linux, SUSE Linux, and major hypervisors like VMware ESXi. HPE provides signed driver sets and firmware updates for these environments, ensuring stable performance and consistent network connectivity across your infrastructure.
Does the 561FLR-T support PXE boot functionality? +
Yes, this adapter supports Preboot Execution Environment (PXE) boot, allowing your servers to boot directly from a network resource. This is a critical requirement for large-scale enterprise deployments where administrators need to automate OS deployment and management via remote imaging servers, reducing the need for manual configuration of individual physical nodes.
Can I request a bulk quote for the HPE 561FLR-T for my enterprise project? +
We frequently assist enterprise clients with high-volume requirements. If you are planning a large-scale data center refresh or require a significant quantity of 561FLR-T adapters, please reach out to our sales team directly. We can provide custom pricing structures and availability schedules tailored to your specific project timelines and budgetary constraints.
Why should I source my HPE networking hardware from BuyRouterSwitch.com? +
