-I am performing an Analysis for server upgrades and at a high level am presenting an explanation of RAID 10 -I am new to RAID and understand some technical aspects and design features -I want to speak to a disaster recovery scenario but do not understand the benefits or more than the 4 drive minimum for the "rebuild" process of a RAID 10 in the event of drive failure -say I have this scenario, 4 minimum drives, say qty
4 36gb, with this I will have 72gb of usable volume
1.) what are the benefits in a RAID 10 with more than the minimum
4 drives, is it additional capacity, more drive loss fault tolerance or both, basically, under what circumstances can a RAID 10 survive multiple simultaneous drive failures
2.) when replacing failed drives in RAID 10 what is the rebuild process, I suppose it depends on the number or drives lost but my guess is that as long as the RAID 10 remains intact after the drive loss the contoller will rebuild when the new functional drive are recognized
