Oracle Advanced Cluster File System (Oracle ACFS) is POSIX Compliant storage management technology, that extends Oracle Automatic Storage Management (Oracle ASM) functionality to support all types of files. It supports Oracle AI Database files and application files, including install files, database data files, database trace files, database alert logs, application reports, BFILEs, and configuration files. Other supported files are video, audio, text, images, engineering drawings, and all other general-purpose application file data. Oracle ACFS presents a mountable file system to any cluster node that can access Oracle ASM.
Oracle Advanced Cluster File System (Oracle ACFS) communicates with Oracle ASM through the Oracle ADVM interface. With the addition of the Oracle ADVM, Oracle ASM becomes a complete storage solution of user data for both database and non-database file needs. I/O requests to Oracle ACFS are passed through Oracle ADVM and the associated IO Drivers. The Metadata required to access the Oracle ASM disk groups is provided through the Oracle ASM Proxy, but the Oracle ADVM drivers access the Oracle ASM blocks directly.
Note: Dynamic volumes supersede traditional device partitioning. Each volume is individually named and may be configured for a single file system. Oracle ADVM volumes may be created on demand from Oracle ASM disk group storage and dynamically resized as required. These attributes make Oracle ADVM volumes far more flexible than physical devices and associated partitioning schemes.
