NVIDIA GPUDirect Storage Release Notes

Release information for NVIDIA® Magnum IO GPUDirect® Storage.

Release information for NVIDIA® GPUDirect® Storage (GDS) for developers and users.

NVIDIA Magnum IO GPUDirect Storage (GDS) is one of the members of the GPUDirect family of technologies. GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage. This direct path increases IO bandwidth, decreases IO latency and reduces the utilization load on the host CPU.

GDS is generally available on third party storage solutions such as DDN EXAScaler, Dell EMC Isilon, IBM Spectrum Scale, NetApp ONTAP and BeeGFS, WekaFS, VAST NFS, Dell Isilon, and Micron. See the Support Matrix for the complete list. GDS documents and online resources provide additional context for the optimal use of and understanding of GPUDirect Storage.
