Sophisticated system configurations require particular disk setups. All common partitioning tasks may be done with YaST. To get persistent device naming with block devices, use the devices below /dev/disk/by-id or /dev/disk/by-uuid. Logical Volume Management (LVM) is a disk partitioning scheme that is designed to be much more flexible than the physical partitioning used in standard setups. Its snapshot functionality enables you to create data backups easily. Redundant Array of Independent Disks (RAID) offers increased data integrity, performance, and fault tolerance.
