Sophisticated system configurations require particular disk setups. To get persistent device naming with SCSI devices, use a specific start-up script. 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.
