Today, we are announcing support for Elastic Fabric Adapter (EFA) and NVIDIA GPUDirect Storage (GDS) on Amazon FSx for Lustre. EFA is a network interface for Amazon EC2 instances that makes it possible to run applications requiring high levels of inter-node communications at scale. GDS is a technology that creates a direct data path between local or remote storage and GPU memory. With these enhancements, Amazon FSx for Lustre with EFA/GDS support provides up to 12 times higher (up to 1200 Gbps) per-client throughput compared to the previous FSx for Lustre version.
You can use FSx for Lustre to build and run the most performance demanding applications, such as deep learning training, drug discovery, financial modeling, and autonomous vehicle development. As datasets grow and new technologies emerge, you can adopt increasingly powerful GPU and HPC instances such as Amazon EC2 P5, Trn1, and Hpc7a. Until now, when accessing FSx for Lustre file systems, the use of traditional TCP networking limited throughput to 100 Gbps for individual client instances. This adoption is driving the need for FSx for Lustre file systems to provide the performance necessary to optimally utilize the increasing network bandwidth of these cutting-edge EC2 instances when accessing large datasets.
With EFA and GDS support in FSx for Lustre, you can now achieve up to 1,200 Gbps throughput per client instance (twelve times more throughput than previously) when using P5 GPU instances and NVIDIA CUDA in your applications.
