5.4.8Enabling WriteCache
You may manually enable the RAID controller’s WriteCache option after creating a RAID set to improve the data transmission performance.
When you enable WriteCache, you may lose data when a power interruption occurs while transmitting or exchanging data among the drives.
The WriteCache function is recommended for RAID 1 and RAID 10 sets.
To enable WriteCache
1.From the Management Menu, select Objects > Adapter, and then press <Enter> to display the adapter properties.
2.Select Disk WC, and then press <Enter> to turn on the option.
