Raid 5 Explanation
Posted on 2006-11-17
I am currently running Raid-5 in a 3 disk scenario. My Dell Server has 6 disk drive slots.
I understand if one disk fails, the other two will continue to function fine.
I will be adding 3 addtional drives for a total of 6.
Which of the following two assumptions is correct:
In a 6 disk (Raid-5) scenario, if one drive is lost, the other five will function fine. The Server would then "rebuild" redundancy in a 5 disk scenario.
If 2 drives fail, 4 would run fine under Raid-5
If 3 driver fail, 3 would run fine under Raid-5
If 4 drives fail, 2 would run fine under Raid-5
If 5 drives were lost, all data would be lost
If any two of the six drives fail, all data would be lost.
Thanks for your help.
