Product Description
The HP 789005-B21 is a high-performance dual-port 10 Gigabit Ethernet Network Adapter designed to meet the demanding network connectivity needs of modern servers. Featuring two 10Gb/s Ethernet ports, this adapter significantly increases network throughput, making it ideal for environments such as data centers, high-performance computing clusters, and storage area networks where high bandwidth and low latency are critical. This adapter utilizes the PCI-Express 2.0 x8 interface, providing ample bandwidth to support the full speed of both 10Gb/s ports simultaneously. The PCIe 2.0 standard offers a theoretical bandwidth of up to 4 GB/s in each direction for an x8 slot, ensuring that the network adapter is not a bottleneck for network traffic. The adapter typically uses SFP+ (Small Form-factor Pluggable Plus) connectors, allowing for flexible deployment with various types of optical transceivers (sold separately) to match specific network infrastructure requirements. Based on advanced networking technology, likely from Mellanox (such as the ConnectX-3 series), this adapter offers robust features for efficient network traffic management, including support for technologies like TCP/IP offload, RDMA (Remote Direct Memory Access) in some configurations, and advanced Quality of Service (QoS) features. Its server-grade design ensures reliability and performance for mission-critical applications, enabling faster data transfers, improved application response times, and enhanced overall network efficiency.
