[Wrf-users] Global File System on a Red Hat Linux cluster

Hi Doug,

I've recently implemented a Dell SAN (MD3000i), using GFS, over
gigabit ethernet. So far the performance has been good enough for WRF
(using 10min. outputs, 4 blades simultaneously), haven't noticed any
difference to a local file system when running the model. File
transfer among hosts are somewhat degraded, but possibly the network
setup is to blame - still have some fine-tunning left to be done.
If you have a SAN system I strongly recommend a clustered storage
solution for its reliability when compared to NFS.

Best Regards,
                Guilherme O. Chagas
