Slide 2: ASM History 101
ASM History 101 The Simple Idea for addressing the complexity of storage management Provide an integrated Stripe and mirror files Automatic rebalances Built on the reliable cluster volume across disks in ASM after storage Oracle instance manager Disk Groups configuration changes architecture I/O ope
Slide 3: Oracle Stack versus Other Host-based Alternatives
Oracle Stack versus Other Host-based Alternatives ASM Host-based LVM/FS ALL database files are striped and mirrored Individual file mount points are created for each automatically across all ASM Disks database. Organizations may have hundreds or even thousands of file systems and virtual volumes to
Slide 4: Evolution of the Oracle Storage Stack
Evolution of the Oracle Storage Stack Efficient Storage Management of Mission Critical Databases Database Oriented Storage Management Grid Infrastructure: Integration with Clusterware Storage Management Efficiency Management for Flex ASM Engineered Automation Systems Data Reliability of storage Data

Slide 6: Flex ASM
Flex ASM Oracle 12c Release 1 Eliminates the requirement for an ASM instance on every server • Database instances connect to any ASM instance in the cluster • Database instances can failover to a secondary ASM instance • Administrators specify the cardinality of ASM instances (default is 3) • Cluste
Slide 7: Diskgroup-oriented Storage Management (12.1)
Diskgroup-oriented Storage Management (12.1) 12.1 Diskgroup Organization • Diskgroups contain files striped across disks and optionally mirrored. Diskgroup • No distinction between individual databases. DB1 : File 1 DB3 : File 3 DB3 : File 1 DB2 : File 1 • Easy to manage, but made consolidation diff
Slide 8: Database-oriented Storage Management (19c)
Database-oriented Storage Management (19c) Flex Diskgroup organization (19c and higher) File Group File Group • New Diskgroup type: Flex Diskgroups • Flex Diskgroups provide File Groups • A File Group is the collection of files belonging Diskgroup to individual databases or PDBs DB1 DB2 DB3 • A File
Slide 9: ASM File Group Flexibility and Availability
ASM File Group Flexibility and Availability Flex Diskgroup quota management Flex Diskgroups enable • Quota Management - limit the space databases can allocate in a diskgroup and Diskgroup thereby improve the customers’ ability to DB1 DB2 DB3 consolidate databases into fewer DGs File 1 File 1 File 1
