What are the different widely used RAID levels and when should I consider them?
I have 6 SAS Harddrive configured on RAID 0. One of my SAS Harddrive has gone faulty, So the server is not working. I tried installing windows server 2003 on a SATA harddisk then connected one SAS harddisk but still its not showing. Can anyone please tell me how can i recover my data??
