Product Description
The HP 647586-B21 is a dual-port 10 Gigabit Ethernet network adapter engineered to provide high-speed connectivity for HP ProLiant servers. Each of the two ports delivers a data rate of 10Gb/s, offering significant bandwidth for demanding network applications such as storage area networks (SANs), high-performance computing (HPC) clusters, and data center virtualization. The adapter's ability to support two independent 10GbE connections enhances network redundancy and aggregation capabilities. Connectivity to the server motherboard is established through a PCI-Express 2.0 x8 interface. This interface provides ample bandwidth to support the full throughput of both 10Gb/s ports, ensuring that the network adapter does not become a bottleneck for network traffic. The PCIe 2.0 x8 interface is a standard for many server platforms, ensuring broad compatibility within the HP ProLiant ecosystem. The FlexibleLOM (FLB) form factor is a proprietary HP design that allows for easy installation and replacement of network adapters directly on the server's motherboard or a dedicated slot. This design simplifies upgrades and maintenance, reducing downtime and simplifying hardware management. The 647586-B21 is an ideal choice for environments requiring robust, high-speed networking capabilities for servers.
