ASM/ACFS Storage Management
ASM

ASM & ACFS are Oracle Storage Services
5
•  Another perspective:
•  ASM/ACFS as a platform for storage
management – Oracle Storage Services.
•  Support applications and databases for
standalone servers and clusters.
•  Moving forward, Oracle Storage Services
provide foundation for cloud computing.

Business Challenge – Need to relocate Databases and
Applications between Servers and Clusters
•  Workload in one server/cluster is at maximum capacity, but there is
available capacity in another server/cluster.
•  Need for planned downtime for maintenance may require relocating a
database or application workload.
