[lustre-discuss] Any documentation regarding caching on RAM?

Could you please explain your problem/configuration more?  Lustre will use RAM for cache on both the clients and servers.  It does impose limits (tunable) on the client RAM usage so that it doesn't interfere with applications. 

Cheers, Andreas
