Determining Usable Storage for Oracle Database Appliance
X6-2-HA
Review the usable disk capacity available for Oracle Database Appliance X6-2-HA and
how capacity is derived.
Oracle Database Appliance X6-2-HA use 1.6TB raw Solid-State Drives, formatted to
1.2TB for performance. The usable data capacity varies because it is derived by
converting disk hardware terabytes (based on 1 kilobyte equals 1,000 bytes) into
software storage terabytes (based on 1 kilobyte equals 1,024 bytes) and splitting the
usable capacity into Oracle Automatic Storage Management (Oracle ASM) disk
groups.
Each of the SSD usable storage is approximately 1.1TB. This is calculated by the
storage usable capacity of the drive converted to TB (1.2 TB divided by 1.024
4
=
1.1TB.)
The following tables provide the approximate amount of usable space for the Oracle
Database Appliance X6-2-HA for the DATA and RECO disk groups.
