1- Raw Disk Capacity defined using standard disk drive terminology of 1 TB = 1000 * 1000 * 1000 * 1000 bytes.<br />
2- Capacity calculated using normal space terminology of 1 TB = 1024 * 1024 * 1024 * 1024 bytes.<br />
3 - Actual space available for a database after mirroring (ASM normal redundancy) and allowing one disk (Quarter<br />
and Half) or two disks (Full Rack) of free space to automatically remirror after disk failures.<br />
