Three Amazon SageMaker training instances must open the same directory tree of bat-detector spectrogram files with ordinary file-path reads, not object GETs. Which store should they share?
Select an answer to reveal the explanation.
Short Explanation
Think of three trainers opening the same spectrogram directory with ordinary file paths. Amazon EFS is that shared POSIX tree. Copying onto each host drifts, and an S3 GET is not a file-path open.
Full Explanation
Amazon EFS fits concurrent POSIX-style access to the same training tree. Copying onto each host wastes space and drifts. S3 object GETs are not ordinary file-path reads. FSx for NetApp ONTAP is the NetApp-reuse path, not the default shared POSIX answer.
