When designing Oracle ASM storage, it is important to match the capabilities of the underlying storage infrastructure to the storage requirements of the database.
The types of disks that are suitable will depend on the quantity of data to be stored and the expected performance needs of the databases located on the ASM storage.
ScaleIO is a software-defined storage solution allowing the user to create a cluster of nodes configured with single or multiple types of storage, along with appropriate caching that act together to deliver storage to applications, meeting any application performance requirements for throughput. I/O operations, and/or latency.
ScaleIO nodes can use spinning disks including high-capacity SATA disks including10k 15K RPM spinning disks, as well as flash drives and Non-Volatile Memory Express (NVMe).
As a general rule:
