what does this mean ? are the queries being translated to something on the block level for example ? i suppose there is no files at all, a new concept of storage that is not files, rather DB objects ?
In answer to the above, no, there are still files. Viewing disk access as a stack of abstractions, ASM replaces the Logical Volume Manager and Filesystem layers, for either datafiles of an Oracle database, or regular files if an ASM Cluster File System (ACFS) is created. 10g and later databases recognize ASM diskgroups as storage targets and can create and grow datafiles in them, most often in an OMF-generated directory/file naming hierarchy. A key feature of ASM is management of shared storage accessed by all nodes of a RAC; versions of RAC prior to 10g had depended on the proprietary shared-storage facilities of commercial Unix offerings. Refer to Oracle Corp. documentation for details. Vike1108 (talk) 17:54, 22 June 2016 (UTC)
LVM ?
The article refers to LVM technology, but doesn't define the abbreviation anywhere. DFH (talk) 20:54, 23 November 2012 (UTC)
