Sophisticated system configurations require particular 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/. 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. For details, see the chapter about multipath I/O in Storage Administration Guide. Starting with SUSE Linux Enterprise 10, there is also the option to use iSCSI as a networked disk. Read more about iSCSI in Section 12.0, Mass Storage over IP Networks—iSCSI.
