My environment is RHEL based, interconnect is infiniband. I have some experience with Lustre. What i want to know is:

  1. Is there a parallel file-system, where if simultaneous write request arrive, they are scheduled on mutually exclusive sets of object servers (to get high fault-tolerance)?

  2. If not, could i tune lustre to schedule simultaneous file-write request on different target disks? I don't mind if i have to disable striping.

Improving fault tolerance while compromising with performance is okay for me.
Any suggestions?

It appears that Lustre does not do data replication for high availability. I believe you can do this with in Gluster but it requires some forethought in regards to replicas. There is also a geo-replication module which can be used to replicate changes off-site but I think it is a separate back end process.
