Hi Apriyanto,

if you have 5 data disk and have 2 copies setup on virtual data store, i suggest to use all 5 for data disk but still depends on cache disk you have. A spare disk is just a recommendation if something happen on existing data disk but as you can see, a Spare Disk is a Useless disk if your data disk is on normal status. If you don't have Spare Disk then some data disk will fail, it still not affect with your production since you have 2 copies of data. Meaning, you still have time to check/replace defective data disk even you don't have spare disk. This practice is to maximize your resources while taking advantage for some features of HCI.

Thanks!

like it only requires disk 2, because duplicates match the number of copies
