Re: Must we use disk-striping

Also sprach "Rob Prop" <rprop@concepts.nl> : :When installing/ordering a new machine for IDS should you use the following :disk-architectures: <snip> :+ Striping : Pos: Data load is balanced over a set of disks : Neg: You don't know which data is on which disk so you can't use :fragmantation optimal Another important negative to striping is that should you lose a single disk, you could lose your entire database. You'd certainly lose any dbspaces containing chunks that were defined on volumes that use the bad disk. If you don't stripe, and set up your volumes such that each dbspace resides on a single physical disk, then losing that disk only loses that dbspace; you can set your system up to stay online when a dbspace goes down (unless it is the rootdbs or contains logs).
