Product Description
The HP 879482-B21 is a high-performance network adapter engineered to meet the stringent demands of modern data centers, particularly those involved in high-performance computing (HPC), artificial intelligence (AI), and big data analytics. Its InfiniBand EDR technology offers unparalleled speed and efficiency, enabling rapid data movement between servers and storage systems. The dual 50Gb/s ports provide substantial aggregate bandwidth, crucial for applications that require simultaneous high-volume data transfers. The adapter's FlexibleLOM (FLR) form factor allows for flexible integration into compatible HP ProLiant servers, simplifying deployment and maintenance. The QSFP+ interface is a standard for high-speed networking, ensuring compatibility with a wide range of InfiniBand switches and transceivers. This design choice underscores its suitability for clustered environments where inter-node communication is a critical performance bottleneck. Beyond raw speed, the InfiniBand EDR protocol offers advanced features such as Remote Direct Memory Access (RDMA) and message signaling interrupts (MSI), which significantly reduce CPU overhead and latency. These capabilities are essential for achieving maximum application performance in tightly coupled parallel processing environments. The 879482-B21 is thus a key component for organizations looking to optimize their infrastructure for data-intensive workloads and achieve faster time-to-insight.
