About General Purpose Storage
Every Oracle Database Appliance has a general-purpose cluster file system created
by default That cluster file system is named
cloudfs
. You can use the
cloudfs
file
system for general-purpose storage of files that must be shared between the servers.
For example, you can use the
cloudfs
file system for staging data loads.
All Oracle ACFS file systems are created on Oracle ASM Dynamic Volumes
provisioned from disk groups that are created in the shared disk storage pool. In a
bare-metal deployment, these file systems are mounted directly in the operating
system hosting the databases. In a virtualized deployment, these file systems are
managed and mounted directly in ODA_BASE.

The storage shelf in the base Oracle Database Appliance X6-2-HA system is half
populated with 10 solid-state drives (SSDs) for data storage, totaling 12TB of raw
storage capacity. The storage shelf in the base system also has four 200 GB high
endurance SSDs for database redo logs to improve performance and reliability. A
separate ACFS file system is created from the REDO diskgroup for redo log files. Add
10 more SSDs on the base system for a total of 20 SSDs and 24 TB of raw storage
capacity.
If you need additional storage, an optional storage expansion shelf is available. With
the optional storage expansion shelf, the raw data storage capacity increases to a total
of 48TB. The expansion shelf contains four 200 GB SSDs to expand the storage
capacity for the database REDO logs. In addition, you can use external NFS storage
outside of the appliance for online backups, data staging, or additional database files.
