Solaris supports six RAID levels from 0 to 6. Only a few storage environments support RAID levels 2, 3, and 4.
The other three RAID levels are most supported by the storage environments.
RAID level 0 - Here, the data are spread across relatively small, equally-sized fragments which are allocated evenly across multiple physical disks.
RAID level 1 - Here, the mirroring technique is used to duplicate the data over two or more physical disks.
RAID level 5 - Here, the striping technique is used to spread the data over the disks in an array. It will have substantial performance degradation when operating with a failed device.
