# Magnum IO GPUDirect Storage ## A Direct Path Between Storage and GPU Memory As datasets increase in size, the time spent loading data can impact application performance. GPUDirect® Storage creates a direct data path between local or remote storage, such as NVMe or NVMe over Fabrics (NVMe-oF), and GPU memory. By enabling a direct-memory access (DMA) engine near the network adapter or storage, it moves data into or out of GPU memory—without burdening the CPU.

See [https://docs.nvidia.com/gpudirect-storage/index.html](https://docs.nvidia.com/gpudirect-storage/index.html) for more information. GDS is currently supported on Linux x86-64 distributions; it is not supported on Windows. When choosing which CUDA packages to download, please select Linux first followed by x86-64 then either RHEL or Ubuntu distributions along with the desired packaging format(s).
