Humm, must of missed this one on the rebound. Anyway, here Disk space is an admin nightmare. Each time we want to reassign disks from one server to another here comes EMC to re-program the Symmetrix array otherwise the SA has the possibility of assigning 2 servers to the same disk. OOPS I really did not wnat to do a newfs on that disk!!!?!??! And at $4000 per disk (72GB) I would not say that their cheap. IDE drives have gotten real cheap, when will SCSI follow suit??
