Viewing the controller properties
The View Controller Information screen allows you to view your controller and firmware properties.
In the System Setup Main Menu, click Device Settings > Dell PERC S150 Configuration Utility > Controller
Management > View Controller Information
The table explains the View Controller Information screen details:
Table 13. View Controller Information
Menu Item Description
PCI ID Displays the PCI ID
Physical disk Count Displays the total number of physical disks available on the
system
Virtual Disk Count Displays the total number of virtual disks available
UEFI Driver Version Displays the UEFI driver version installed on the system
Firmware Build Time Displays the time and date the firmware was last updated.
Managing the physical disk write cache policy for SATA drives
Perform the following procedure to enable the physical disk write cache policy:
1. Enter the Dell PERC S150 Configuration Utility. See Entering the DELL PERC S150 Configuration Utility.
2. Click Physical Disk Management → Select Physical Disk Operations.
3. Click the link Manage Physical Disk Properties.
The Manage Physical Disk Properties screen is displayed.
4. Select one or multiple physical disk to apply the write cache policy.
5. Choose from the following physical disk write cache policies:
Physical disk
write cache
policies
Description
Default The physical disk write cache feature is enabled for:
The physical disk write cache feature is disabled for 6 Gbps HDDs.
● SSDs
● 3 Gbps HDDs
Enable The feature is enabled on the disk selected.
Disable The feature is disabled on the disk selected.
6. Click Apply to save the changes made.
NOTE:
Ensure that you change the physical disk write cache policy of a global hot spare disk after rebuild to the write
cache policy of the last configured virtual disk.
NOTE: In the View Virtual Disk Properties screen, ensure that the physical disk write cache setting is consistent
across the physical disk associated with the virtual disk.
NOTE: If you have Linux RAID configured on the system, you cannot modify the physical disk write cache policy feature
settings.
NOTE: For more information about the physical disk write cache behavior, see the Troubleshooting your system section.
