Frequently Asked Questions (FAQs)
What servers are compatible with the HPE 728987-B21 10Gb 2-port 571SFP+ NIC? +
This network interface card is specifically engineered for select HPE ProLiant Gen8 and Gen9 server series. It utilizes a standard PCIe form factor designed to integrate seamlessly into the server's mezzanine or expansion slots. We recommend verifying your specific server model’s quickspecs to confirm PCIe lane compatibility and physical space requirements for the card before deployment.
Does the HPE 571SFP+ 10Gb NIC support both SR and LR transceivers? +
Yes, the 728987-B21 provides flexibility for your fiber-optic infrastructure. It supports various SFP+ transceiver modules, including 10GBASE-SR for short-reach multi-mode fiber and 10GBASE-LR for long-reach single-mode fiber applications. Always ensure the SFP+ modules used are compatible with the HPE hardware standards to maintain optimal signal integrity and link stability across your data center environment.
What is the primary performance benefit of using the HPE 728987-B21 in a virtualized environment? +
The 571SFP+ adapter excels in high-density virtualized environments by offloading network traffic processing from the server CPU. By leveraging advanced hardware-based features, it significantly reduces latency and lowers CPU utilization, allowing your host servers to dedicate more resources to running virtual machines and applications, effectively increasing your overall cluster efficiency.
How does the HPE 728987-B21 handle port failover and redundancy? +
This dual-port NIC supports various teaming configurations, such as NIC bonding and failover, through the host operating system or server management software. By configuring both 10Gb ports, you can ensure high availability; if one physical link or switch connection experiences an issue, the traffic is automatically redirected to the secondary port, maintaining continuous network uptime for critical production workloads.
Does the 571SFP+ adapter require specific driver installations for Windows or Linux? +
While modern operating systems may include generic drivers, we highly recommend installing the latest HPE-specific drivers and firmware packages. These are available through the HPE support portal and ensure that all advanced features, such as VLAN tagging, jumbo frames, and offload engines, are fully enabled and optimized for your specific server operating environment.
What is the maximum throughput per port for the HPE 728987-B21? +
The HPE 728987-B21 is a high-performance 10 Gigabit Ethernet adapter. Each of the two SFP+ ports provides full-duplex, line-rate 10Gbps connectivity. This provides a total aggregate bandwidth of 20Gbps per card, making it an ideal choice for bandwidth-intensive tasks like database replication, storage area network access, and high-speed internal server-to-server communications.
Can I use the HPE 728987-B21 for iSCSI offload tasks? +
Yes, this card is designed to handle demanding networking protocols efficiently. It supports iSCSI hardware offloading, which enables the adapter to process storage traffic directly. This reduces the overhead on the server's primary processor, resulting in improved storage throughput and lower latency for iSCSI-based storage arrays connected to your server infrastructure.
How do I manage the firmware settings for this HPE NIC? +
Management is typically handled through the HPE Integrated Lights-Out (iLO) interface or the UEFI System Utilities. These tools allow you to update firmware, configure boot-from-SAN settings, and adjust advanced port parameters without needing to boot into the primary OS. This streamlined management approach ensures that your networking hardware remains up-to-date and correctly tuned for your production requirements.
