Explanation:
ASM extends the power of Oracle-managed files. With Oracle-managed files, files are created and managed automatically for you, but with ASM you get the additional benefits of features such as mirroring and striping. ASM enables you to change the storage configuration without having to take the database offline. It automatically rebalances-redistributes file data evenly across all the disks of the disk group-after you add disks to or drop disks from a disk group. Should a disk failure occur, ASM automatically rebalances to restore full redundancy for files that had extents on the failed disk.
