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