The HP 615406-001 model, known as the HP NC552SFP, is a 10Gb 2-Port Ethernet Adapter designed to deliver high-performance, low-latency networking solutions for HP servers. This adapter utilizes the SFP+ (Small Form-factor Pluggable Plus) interface, allowing for the use of Direct Attach Cables (DAC) or fiber optic transceivers to connect to network switches or other networked devices. The NC552SFP is based on Emulex's OneConnect Universal Converged Network Adapter (UCNA) architecture, offering high bandwidth and throughput for data center environments. With support for hardware offloads, including TCP/IP and Fiber Channel over Ethernet (FCoE), it reduces CPU load, thereby enhancing overall system performance. Dual ports provide redundancy and increased capacity for mission-critical applications. Ideal for virtualized environments, this adapter supports VMware NetQueue and Microsoft VMQ, optimizing network traffic management. Its flexibility and performance make it an excellent choice for organizations looking to upgrade their server connectivity to 10Gb Ethernet while ensuring compatibility with a broad range of network infrastructures.
