Product Description
The Dell J39HD network adapter, powered by the Intel E810XXVDA2 controller, delivers exceptional network performance with its dual 25Gb Ethernet SFP28 ports. This adapter is engineered to meet the stringent demands of modern data centers, offering high throughput and low latency essential for applications such as high-performance computing (HPC), demanding storage solutions, and large-scale data analytics. Its PCIe Gen3 x8 interface ensures a robust connection to the server's motherboard, minimizing bottlenecks and maximizing data transfer speeds. This adapter supports a suite of advanced networking technologies, including RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE) and iWARP, which significantly reduce CPU overhead by allowing direct memory access between network-connected systems. Features like Single Root I/O Virtualization (SR-IOV) further enhance performance and efficiency in virtualized environments by providing dedicated hardware resources to virtual machines. The inclusion of a low-profile bracket ensures compatibility with a wider range of server chassis, including dense rack-mount systems. Designed for reliability and performance, the Dell J39HD is an ideal choice for organizations seeking to upgrade their network infrastructure to support next-generation applications and data growth. Its ability to handle massive data flows and offload network tasks from the CPU makes it a critical component for optimizing server utilization and overall system performance in enterprise-level deployments.
