Description of the I/O Count parameter in a file pool policy of OceanStor 9000

0

The I/O Count parameter specifies a storage tier based on the number of times that a file is accessed within a specific statistical period. The statistical period ranges from 1 to 7 days.
The methods of calculating I/O counts vary when different protocols or versions are used.
- When the NFSv3 protocol is used, each I/O operation is considered an I/O count. For example, if you open a file and close it after performing 10 write operations for the file, the I/O count value is 10.
- When the NFSv4 or CIFS protocol is used, each complete file operation, that is, opening and closing a file, is considered an I/O count. For example, if you open a file and close it after performing 10 write operations for the file, the I/O count value is 1.
