Amazon SageMaker customers can now use smaller Amazon FSx for Lustre file systems as the data source for training machine learning models. Until today, the smallest FSx for Lustre file system that could be created was 3.6 TBs. For training sets that are smaller than this size, customers can now create and use file systems as small as 1.2 TB.
