Well, for a file server like NFS/Samba, you could also consider raid10,f2. I would think you could get about double the read performance compared to n2 and o2 layouts, and also for individual read transfers on a running system you would get somthing like double the read performance. Write performance could be somewhat slower (0 to 10 %) bot as users are not waiting for writes to complete, they will probably not notice. best regards keld _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
