#Oracle disk manager driver#
The Oracle ASM Dynamic Volume Manager (Oracle ADVM) provides volume management services and a standard disk device driver interface to clients. Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a multi-platform, scalable file system, and storage management technology that extends Oracle ASM functionality to support customer files maintained outside of Oracle Database. This capability simplifies the integration of Oracle ASM into pre-existing environments.
Oracle ASM files can coexist with other storage management options such as raw disks and third-party file systems. The smaller number of disk groups consolidates the storage for multiple databases and provides for improved I/O performance. Oracle ASM reduces the administrative overhead for managing database storage by consolidating data storage into a small number of disk groups. OMF also names files and removes them while relinquishing space when tablespaces or files are deleted. OMF automatically creates files in designated locations. Oracle ASM also uses the Oracle Managed Files (OMF) feature to simplify database file management. You can use external redundancy to enable a Redundant Array of Independent Disks (RAID) storage subsystem to perform the mirroring protection function. The Oracle ASM normal and high redundancy disk groups enable two-way and three-way mirroring respectively. The Oracle ASM volume manager functionality provides flexible server-based mirroring options. For information about administering disk groups, see Chapter 4, "Administering Oracle ASM Disk Groups". When you add or remove disks from a disk group, Oracle ASM automatically redistributes the file contents and eliminates the need for downtime when redistributing the content. You can add or remove disks from a disk group while a database continues to access files from the disk group. The performance is comparable to the performance of raw devices. The content of files that are stored in a disk group is evenly distributed to eliminate hot spots and to provide uniform performance across the disks. Within a disk group, Oracle ASM exposes a file system interface for Oracle database files. Oracle ASM uses disk groups to store data files an Oracle ASM disk group is a collection of disks that Oracle ASM manages as a unit. Oracle ASM is Oracle's recommended storage management solution that provides an alternative to conventional volume managers, file systems, and raw devices. Oracle ASM is a volume manager and a file system for Oracle database files that supports single-instance Oracle Database and Oracle Real Application Clusters (Oracle RAC) configurations. You can use it to partition a hard drive, format a drive or change a drive letter easily.Overview of Oracle Automatic Storage Management If you’re not sure which tool you can use, we recommend using Acronis Disk Director 12. Acronis Disk Director 12 is a well-known drive management tool around the world. Most of the drive management tools are user-friendly, which allow you to manage the drives easily. If you find it not easy to use Disk Management to manage the drives, you can use a third-party drive management tool instead.
