Frequently Asked Questions
Is the HPE 779799-B21 available refurbished? +
Yes. This page lists the refurbished condition currently available from BuyRouterSwitch. Availability can change, especially for bulk orders.
Can I request bulk pricing for 779799-B21? +
Yes. Businesses, resellers, MSPs, government buyers and procurement teams can request custom quantity pricing.
Does BuyRouterSwitch ship 779799-B21 internationally? +
BuyRouterSwitch ships enterprise IT hardware to customers in the United States and international markets, subject to destination and product restrictions.
What server platforms are compatible with the HPE 546FLR-SFP+ adapter? +
This flexible-lom (FLR) adapter is specifically engineered for HPE ProLiant Gen9 and Gen10 rack servers. It utilizes the dedicated mezzanine slot on the system board, which saves valuable PCIe slots for other expansion cards while providing high-speed 10Gb connectivity tailored for integrated HPE chassis designs.
Does the 779799-B21 support advanced network offloading features? +
Yes, this adapter supports advanced offloading capabilities, including RDMA over Converged Ethernet (RoCE), TCP/IP offload, and tunnel offload protocols like VXLAN and NVGRE. These features reduce CPU utilization significantly, allowing your server to dedicate more processing power to business-critical applications rather than managing network traffic overhead.
What kind of transceiver modules should I use with this 10Gb mezzanine card? +
The 546FLR-SFP+ features two SFP+ ports that accommodate various 10Gb connectivity options. You can use SFP+ Direct Attach Copper (DAC) cables for short-reach top-of-rack connections or SFP+ SR/LR optical transceivers for longer distances. Ensure you select genuine HPE-compatible optics or cables to maintain hardware integrity and performance within your network fabric.
How does the performance of the 546FLR-SFP+ compare to standard PCIe cards? +
By leveraging the FLR form factor, this adapter connects directly to the server's internal bus via the mezzanine connector, providing a streamlined path for data. It delivers high-bandwidth, low-latency 10GbE performance comparable to high-end PCIe cards, but it frees up your external PCIe risers for storage controllers, GPUs, or additional network interface cards.
Is the HPE 546FLR-SFP+ suitable for high-performance virtualization environments? +
Absolutely. With its dual-port 10Gb capacity and comprehensive support for SR-IOV (Single Root I/O Virtualization), this card is ideal for virtualized server environments. It allows virtual machines to bypass the hypervisor and access network resources directly, which minimizes latency and maximizes throughput for busy multi-tenant server workloads.
Can I use the HPE 546FLR-SFP+ in a standard PCIe slot? +
No, this is a FlexibleLOM (Mezzanine) card designed strictly for use in the dedicated FLR slots found on compatible HPE ProLiant rack servers. It will not fit into a standard PCIe expansion slot. If you require a standard PCIe adapter for a different server type, please browse our inventory for PCIe-based network interface cards.
What management features are available for this network adapter? +
This adapter integrates seamlessly with HPE iLO (Integrated Lights-Out) and OneView management software. Administrators can monitor network health, configure port parameters, and deploy firmware updates remotely through the standard HPE management interface. This centralized control simplifies maintenance tasks and ensures consistent network configurations across your entire data center server fleet.
What is the power consumption profile for the 779799-B21 adapter? +
The card is designed for energy efficiency within the server thermal envelope. By utilizing advanced power management features, it adjusts its energy consumption based on current traffic loads. This helps maintain the overall power efficiency targets of your server configuration while ensuring sufficient performance for demanding 10Gb networking tasks.
How can I obtain a bulk quote for the HPE 546FLR-SFP+ adapter? +
