Description
The HP 661686-001 is a high-performance Host Channel Adapter (HCA) that brings the power of 40 Gigabit InfiniBand to HP ProLiant Gen8 servers. InfiniBand is a specialized interconnect technology known for its extremely low latency and high bandwidth, making it the preferred choice for demanding applications such as High-Performance Computing (HPC) clusters, high-speed storage solutions, and high-frequency trading platforms. This adapter provides two 40Gb/s InfiniBand ports, enabling rapid communication between servers and storage devices or other nodes in a cluster. Equipped with QSFP (Quad Small Form-factor Pluggable) connectors, the 544FLR-QSFP adapter supports high-density cabling and offers flexibility in network topology. The adapter utilizes a PCI Express 3.0 x8 interface, which provides sufficient bandwidth to fully leverage the capabilities of the dual 40Gb/s InfiniBand links. This combination ensures that data can be moved quickly and efficiently, minimizing bottlenecks and maximizing application performance. The 544FLR-QSFP designation indicates its FlexibleLOM (LAN on Motherboard) form factor, designed for seamless integration into specific HP ProLiant server models, particularly the Gen8 generation. This integration ensures optimal performance, reliability, and manageability within the HP ecosystem. The HP 661686-001 is a critical component for organizations pushing the boundaries of computational power and requiring the fastest possible interconnects for their most demanding workloads.
