[gpfsug-discuss] AFM vs mmremotefs

[Marc A Kaplan]

I think you "got it" -  despite the name "remote" - mmremotefs is an 
access method and a way of organizing your data and machines into several 
clusters - which can work great if your network(s) are fast enough.   For 
example you can have one or more client clusters with no GPFS(Spectrum 
Scale) file systems stored "locally".  And one or several  clusters that 
are servers to those client clusters. 

AFM is about caching and replicating files...   You might do that because 
of "remote-ness" - or for other reasons...

When does it make sense to use mmremotefs vs AFM?  With mmremotefs the 
actual data lives on the remote cluster right so if you need data closer 
then AFM make more sense to use?  If the clusters get disconnected with 
mmremotefs I have not access to the data with AFM I do. 
 
Do I have these concepts right in my head?
