5.2.8Enabling 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.
