Our filesystem on our NNAS is IBM GPFS. All of our compute nodes are diskless. They all load from the identical image. Each node runs EXT4 each core is assigned 2GB of memory Each node has 4 10GB Myrnet adapters connected to a Myricom Myrinet 128 port 10Gb. these Myrinet switches connect to our NAS with 10GB Myrinet connectors.
Our systems use XFS and EXT4. I have not seen any articles showing user experiemnce of ZFS. I was dissapointed in the analysis of the EXT4 files system which read like a wet tongue in the lips RASPBERRY. I have run into two systems that had a problem on their EXT4 files system but those were easily corrected with reboot and repair on reboot. the OS we use are SLES. our communications modules are compiled into the kernel. This includes MPICH MVAPICH. The system is tuned for our CFD needs. We see ZFS as an untested and unproven filesystem.
