Sophisticated system configurations require specific disk setups. All
common partitioning tasks can be done with YaST. To get persistent
device naming with block devices, use the block 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 easy creation of data backups. Redundant Array of
Independent Disks (RAID) offers increased data integrity, performance, and
fault tolerance. SUSE Linux Enterprise Server also supports multipath I/O
(see Section 7.0, Managing Multipath I/O for Devices,
(↑SLES 11 SP2: Storage Administration Guide) for
details), and there is also the option to use iSCSI as a
networked disk (read more about iSCSI in
Section 13.0, Mass Storage over IP Networks: iSCSI,
(↑SLES 11 SP2: Storage Administration Guide)).
