（1）63 disk groups in a storage system
（2）10,000 ASM disks in a storage system
（3）2 terabyte maximum storage for each ASM disk (the Bug 6453944 allowed larger sizes, but that led to problems, see Note 736891.1 "ORA-15196 WITH ASM DISKS LARGER THAN 2TB")
（4）40 exabyte maximum storage for each storage system
（5）1 million files for each disk group
（6）2.4 terabyte maximum storage for each file
