Hi All,
We are installing a new server at HR Chelmsford and my technical guys has asked the following question:-
We have 2 ways of arranging the 3 drives. My initial idea was to have 1 drive as a mirror of the other (RAID 1, what we have now for the Audio/data folders) with the third as a 'Hot' spare - if one of the 2 drives failed then the spare would kick-in and replace it. Meaning we would regain a fault tolerant RAID automatically within minutes. It is not something we have had before, whether it is worth it is up for debate.
Another option is to arrange the 3 discs as RAID 5. This may give better performance and would give more capacity. It would also mean that if a disc failed we would lose fault tolerance until we replaced the failed drive (rather like we have now) However because there are 3 discs rather than 2 there is a 50% greater likelihood of a disc failure at some point.
Does anyone have an opinion on this or not. Should we do Raid 1 or Raid 5? Or something completely different? |
