SSD Disk Cache Policy

The MegaRAID firmware provides support to change the write-cache policy for SSD media of individual physical drives.

The MegaRAID firmware does not allow any user application to modify the write-cache policies of any SSD media. The host applications can modify this property through a new logical device (LD) addition or a LD property change. When SSDs are configured in a mixed disk group with HDDs, the Physical Device Write-Cache Policy setting of all the participating drives are changed to match the SSD cache policy setting.

Follow these steps to view the SSD cache property.

1.	Click the controller node in the device tree.
