5.2.8Enabling the Disk Write Cache (DWC)
You may manually enable the RAID controller’s Disk Write Cache option after creating a RAID set to improve the data transmission performance.
When you enable DWC, 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. You have to manually configure the Adapter and the Virtual Drive of the RAID set you created.
To enable DWC:
1.From the Management Menu, select Objects > Adapter. Select an existing adapter then press <Enter> to display the adapter properties.
2.Select Disk WC then press <Enter>.
