When creating an aggregate and adding capacity disks to an aggregate, you should understand the rules that are applied when displaying disk types and disk RPM.
When the disk type mixing and disk RPM mixing options are not enabled, the actual disk type and actual disk RPM are displayed.
When these mixing options are enabled, the effective disk type and effective disk RPM are displayed instead of the actual disk type and actual disk RPM. For example, when the disk mixing option is enabled, System Manager displays BSAS disks as SATA. Similarly, when disk RPM mixing is enabled, if the RPM of the disks is 10K and 15K, System Manager displays the effective RPM as 10K.
