The NFS server is supporting our internal systems, and our ftp/webservers. We have a lot of systems that use the NFS service as a queue, moving files from directory to directory at different stages of processing. Snapshots and replication are important. I'd prefer the ability to make a snapshot writable for testing (if that's what you mean by cloning) but I don't think Isilon can do that. > What are you currently running on, and is it meeting your performance > needs? We're on a EMC NS80. The back-end array is set up as mirrored pairs of 146G 15k disks, and we've been struggling with hot-spots on the volumes. The Celerra now supports raid10 on the back-end, and we're considering re-laying out the back-end storage now that it'san option, but in order to do that we need to move everything off or add more storage. I'm particularly interested in performance analtyics tools. We've got Sun's 7000 systems as our tier2 storage, and that level of data is good. EMC's actually got a pretty good toolset, but it's split into an NFS-centric view and a storage-centric view. It takes some work to combine the two views to understand issues. thanks! -j _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
