Home directories will remain on local storage, boot volume. The NAS will be strictly for FCP projects (use case 1), and strictly photo editing (use case 2). With the initial implementation, it will not be based on distributed storage so it sounds like a static mount is adequate. However, if there's a move to distributed storage it sounds like automounting is dynamic and thus more appropriate. There's a DAS vs NAS bandwidth question that I'll have to sort out separately[1] - it might make sense to go with a small amount of fast DAS as scratch, work in-progress, type space, where they pull projects off the NAS, work on them, and push them back. > > However, I do use static mounts, so the NFS volumes are mounted at boot and > stay mounted.

Are you using NFS v4 on 10.7, or NFS v3? [1] Funny enough, it's the hard core photographers doing HDR compositing in 32bpc float with well over 2+GB single document files (multiple layers, multiple Raw files, all composited in a single .PSB) that need more storage performance due to the extreme peak needed. While working on the file, not much at all is needed, unlike video. Whereas when they do a command-s periodically to save what they're working on, it's a more extreme bitrate than video (but of course it's not a critical one, if slow there are no dropped frames, but it can mean waiting around for a while for a machine that's effectively useless until the file is saved). _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
