Hello List, Just wanted to get some opinions about whether disk staging units are worthwhile. My backup server has two BasicDisk staging units with the storage units configured such that the data goes to disk and is then moved to tape. I have a tape library with four LTO-3 drives connected via FC. So what I'm wondering is, since the LTO drives are reasonably fast, and since I'm writing the data ultimately to tape anyway, would it be better to just write directly to tape. The disk is just old fashioned spinning disk with no de-duplication so there are operational costs for the disks. All tape and disk storage units are local to the backup server. I'm thinking it would be better to add LTO drives and eliminate the disk for now and maybe later add a de-duplicating disk unit.
Under what circumstances does it make sense to stage data on disk. I would appreciate hearing what your thoughts and experiences are with regard to disk staging. Thanks, Vic _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
