I am trying to find answers to an age old question of NFS vs Parallel file
systems. Specifically - Isilon oneFS vs parallel filesystems.Specifically
looking for any technical articles or papers that can help me understand
what exactly will not work on oneFS.
I understand that at the end - it all depends on workloads.
But at what capacity of metadata io or a particular io pattern is bad in
NFS.Would just getting a beefy isilon NFS HDD based storage - resolve most
of the issues?
I am trying to find sources that can say that no matter how beefy an NFS
server can get with HDDs as backed - it will not be as good as parallel
filesystems for so and so workload.
If possible - Can anyone point me to experiences or technical papers that
mention so and so do not work with NFS.
Does it have to be that at the end - i will have to test my workloads
across both NFS/OneFS and Parallel File systems and then see what would not
I am concerned that any test case might not be valid, compared to real
shared workloads where performance might lag once the storage reaches PBs
in scale and millions of files.
