We are looking for to choose a clustered file system for our in house appplication.

Let me first highlight my requirement.

we have a storage and 2 servers at present.We get the data files from remote servers to our server and on both servers we are running our application to access those data and make a final result as per our requirements.

In future may be after 3-4 months, we can add another servers in current cluster pool to handle more data load from remote location data senders.

So my requirement is that to integrate same storage partition on 2-3 servers , it might be 4-5 more servers in future,

My application read data from storage partition and write back to storage partition.

Is there any bottleneck / limitation from RHCS , GFS2 or anything.?

We are new with RHCS + GFS and all. Can we have any other better approach or someway to deal with our requirement light way?

what is the best OS version for this ? how's RHEL 6.4 64 bit ?

please share some case study or some gudie reference as per past experiences with such environnmnets
