How many file servers do you already have? If you're already set up with several file servers, then you might want to split the 1-TB into multiple VM's, with a single /vicepa per VM. An advantage of this is you have more AFS servers to choose from when you want to create replicated volumes (assuming you *do* want to create replicated volumes). Also that means there is less data on any one file server when it comes times to do upgrades, or if there is a problem on one server. (This hit us recently at RPI, where we had some file- system corruption on one file server after multiple hardware crashes). The disadvantage is that you have more servers to keep track of, and with more servers you have more chances for something to go wrong! Another factor which might influence your choice is how large is the average AFS volume which you create? If you're creating 10-gig AFS volumes then you might be happier with more file servers, but if you're creating 100-gig AFS volumes then you'd probably want fewer 'vice' partitions, with a larger size per partition. -- Garance Alistair Drosehn = [email protected] Senior Systems Programmer or [email protected] Rensselaer Polytechnic Institute; Troy, NY; USA _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
