Frequently Asked Questions
What servers are compatible with the HPE 817753-B21 NIC? +
The HPE Ethernet 10/25Gb 2-port SFP28 MCX4121A-ACUT is designed specifically for integration with HPE ProLiant Gen10 and Gen10 Plus servers. It utilizes a standard PCIe form factor, making it ideal for high-density rack and tower server environments that require robust, high-speed network connectivity while maintaining full compatibility with the HPE ecosystem.
Does the 817753-B21 support both 10Gb and 25Gb connection speeds? +
Yes, this dual-port network interface card is engineered to provide flexible connectivity. It supports both 10GbE and 25GbE speeds, allowing administrators to transition their infrastructure to faster 25Gb standards while maintaining backward compatibility with existing 10Gb SFP+ network environments, ensuring a smooth upgrade path for data centers.
What type of optical transceivers or cables are required for this NIC? +
This adapter features two SFP28 ports. To achieve optimal performance, you should use SFP28 optical transceivers or Direct Attach Copper (DAC) cables designed for 25GbE operation. The card is also compatible with 10GbE SFP+ modules, provided the cabling infrastructure meets the requirements for your specific short-range or long-range network links.
How does the MCX4121A-ACUT chip help with server CPU overhead? +
The MCX4121A-ACUT chip utilizes advanced hardware offloading technologies to handle network traffic processing. By offloading tasks such as TCP/UDP checksums, large send offload, and Receive Side Scaling (RSS) directly on the NIC, the card significantly reduces the load on the host server's CPU, leaving more processing power available for your critical enterprise applications.
Is this HPE NIC suitable for virtualization environments? +
Absolutely. This card is an excellent choice for virtualized deployments due to its support for Single Root I/O Virtualization (SR-IOV). This technology allows a single physical PCIe device to appear as multiple separate physical devices, providing virtual machines with direct access to the hardware for near-native network performance and reduced latency in dense VM environments.
What is the physical form factor of the HPE 817753-B21? +
The HPE Ethernet 10/25Gb 2-port SFP28 MCX4121A-ACUT is a standard low-profile PCIe form factor card. It is typically supplied with both full-height and half-height brackets, making it versatile enough to fit into a wide variety of server chassis, including 1U and 2U rack servers where space is at a premium.
Can I use this card for RDMA over Converged Ethernet (RoCE)? +
The MCX4121A-ACUT chipset supports RoCE, which is a critical feature for high-performance computing and storage applications. By enabling RDMA, the card allows for memory-to-memory data transfers between servers without involving the operating system or CPU, resulting in ultra-low latency and significantly higher throughput for storage-heavy or database-intensive workloads.
How is the 817753-B21 managed within an HPE server environment? +
Management is streamlined through standard HPE tools and native operating system drivers. Since it is an HPE-branded component, it integrates seamlessly with HPE iLO (Integrated Lights-Out) for system-level inventory and monitoring, ensuring that administrators can easily track the status and health of the network adapter alongside other vital server hardware components.
Does BuyRouterSwitch.com offer bulk pricing for these HPE NICs? +
Yes, we specialize in supporting large-scale infrastructure projects. If you are planning a data center refresh or need to outfit multiple server racks, our team can provide competitive bulk quotes tailored to your specific volume requirements. Simply reach out to our sales department with your quantity needs, and we will prepare a professional procurement proposal for your business.
Why should I purchase the HPE 817753-B21 from BuyRouterSwitch.com? +
