Oracle Disk I/O Tuning

Chapter 5:

ASM Files

ASM Disks

The unit of storage for ASM disk groups is ASM Disks. ASM disks can be entire physical disks, LUN(s) from a storage array, partition of a LUN or pre-created files in a NAS filer. An ASM disk name is common to all nodes of the cluster. The administrator can specify the disk name, or it will be automatically generated by ASM when a disk is added to a disk group. Since different hosts can use different operating system names to refer to the same ASM disk, the ASM disk name abstraction is required.

To reduce the chances of losing data in case of single disk failure, ASM provides mirroring. If disk mirroring weren’t provided, the loss of the unduplicated data from a single ASM disk would possibly damage every file in the disk group.
