大家在搭建数据库的时候需要注意，使用ASM磁盘单盘不要超过2T，个人一般设置为200G 或者500G 单盘。

Oracle ASM Storage Limits
Oracle ASM provides near unlimited capacity for future growth, but does have some storage limits. For example, Oracle ASM has the following limits on the number of disk groups, disks, and files:

63 disk groups in a storage system

10,000 Oracle ASM disks in a storage system

1 million files for each disk group

Without any Oracle Exadata Storage, Oracle ASM has these storage limits:

***2 terabytes (TB) maximum storage for each Oracle ASM disk***

20 petabytes (PB) maximum for the storage system

With all Oracle Exadata Storage, Oracle ASM has these storage limits:

4 PB maximum storage for each Oracle ASM disk

40 exabytes (EB) maximum for the storage system

The maximum size limit of a disk group equals the maximum disk size multiplied by the maximum number of disks in a disk group (10,000).

The maximum number of disks across all disk groups is 10,000. The 10,000 disks can be in one disk group or distributed across a maximum of 63 disk groups. This is a limitation on the number of Oracle ASM disks, not necessarily the number of spindles. A storage array could group multiple spindles into a LUN that is used as a single Oracle ASM disk. However Oracle ASM is currently limited to 2 TB in a single disk unless using Oracle Exadata storage.
