The storage configuration shown in the following table is used to explain how to calculate the amount of data of the SMF records that are output by MAR.
| Component |
Quantity |
|---|---|
| MPU |
4 (Number of MPs per MPU: 8) |
| CLPR |
1 (For CLPR0 only) |
| Parity group |

| Port |
8 (Active port with MF Target attribute) |
| LDEV |
1,024 (Number of control units: 4; number of LDEVs per control unit: 256) |
The following table shows the amount of data of the SMF records that are output for each interval.

The amount of data of the SMF records to be output for each interval is 130,768 bytes (approximately 128 KB).
Assuming that the amount of output data per interval is 128 KB, the amount of data of the SMF records output in each period when the interval is 15 minutes is calculated as shown in the following table.
