Dell EMC engineers monitored additional CPU usage over the duration of the backup on the PowerEdge R940 servers. The findings show consistent CPU usage of 2.5 percent to 3.3 percent during the backups.
The following table shows the average additional CPU usage during backups.
Table 3. Average CPU usage during backups
Backup |
Average CPU usage (percentage) |
First backup of 1.3 TB SAP HANA database |
2.5 |
Second backup of 1.39 TB SAP HANA database |
3.3 |
Third backup of 1.43 TB SAP HANA database |
3.02 |
For each SAP HANA database, the entire server was dedicated to supporting the database, which is consistent with standard practice in production environments. Therefore, the average CPU usage was across 112 physical cores in the server during the backup. While every customer environment is different, our findings show a low average additional CPU usage during the backups.
