M201 How Data is Stored on Disk

I am using Atlas for my Database and collections. On watching this video I would like to know how you can set up my Atlas database to take advantage of Paralelisation of I/O? It would seem that while this class is good, it appears to be geared to a manual install. Is there any reference or way to set this up on my atlas cluster?

Also… If I use this format, would I use one cluster for the database and another for the index? or are the disks contained on the same cluster? To quote the lecture.



How is this structure in Atlas? And how can you verify it in Atlas?
