I am about to implement a cluster of two F820's each with three DS14 shelves. To complicate things I am going to use SyncMirror to mirror a couple of the more important volumes. Does anyone have any experiences they would like to share having a similar setup? I would particularly like to find the answer to the following:
- Can disks in the same volume be spread over 2 disk pools?
Please don't do this. The reason there are two pools is so that each of the plexes (copies) of the volume can be in a separate pool for fault isolation. The pools are created such that a loop or adapter failure cannot take out both plexes.
- Can disk spares be shared amongst disk pools?
Normally spares are specific to a single pool. The exception would be in the case where no spare is available in the same pool as a failing disk AND the failing disk leaves the volume in the position where another failure could lead to the loss of the volume. -Steve
