Dell provides cost effective RAID support through PERC (PowerEdge Raid Controller) S100, S300 and S110. At present Dell doesn’t support any of these controllers with Windows Server 2012, however Dell is working to support PERC S110 in future.

The PERC S100 and S300 controllers do not have support for Microsoft Windows Server 2012 and there is no plan to support these controllers with Microsoft Windows Server 2012 in future. Customers who are using Dell servers with PERC S100 and S300 controllers have to switch to one of the below alternate options if they want to install Microsoft Windows Server 2012 on their servers.

 

Option1: Converting PERC S100/S110 into on-board SATA controller

Note: No data is migrated and this is not a replacement of PERC S100 solution. Data needs to be backed up before following the below steps.

  1. Power on the server and press F2 to enter the BIOS settings.
  2. Enter the BIOS setup -> SATA settings option and change it to ATA or ACHI mode whichever is available. Refer Figure-1.
  3. Save and Exit the setup.
  4. Boot from the Microsoft Windows Server 2012 DVD and complete the installation.

 

Option2: Switching to on-board SATA controller from PERC S300

Note: No data is migrated and this is not a replacement of PERC S300 solution. Data needs to be backed up before following the below steps.

  1. Open the server and remove the internal SATA cables connected to the S300 controller and connect it to the On-Board SATA controller ports of the server.
  2. Power on the server and press F2 to enter the BIOS settings.
  3. Enter the BIOS setup -> SATA settings option and change it to ATA or ACHI mode whichever is available. Refer Figure-1.
  4. Save and Exit the setup.
  5. Boot from the Microsoft Windows Server 2012 DVD and complete the installation.

Option 3: Buying a new supported PERC controller from Dell

You can purchase additional supported RAID controllers via the spare parts sales teams with a phone call to Dell or you can also order online via the S&P sales catalog.  To order online, go tohttp://accessories.dell.com and search for “PERC”.

 

Microsoft Windows Server 2012 provided RAID solution:

Installing Microsoft Windows Server 2012 utilizing the on-board SATA controller doesn’t provide data redundancy. In the event you want data redundancy, you can use the software raid functionality provided by the Microsoft Windows Server 2012 operating system.

  1. Go to disk management.
  2. Right click on the disks and convert it to dynamic disk.
  3. Right click on the volume for which you want redundancy and create “Mirrored Volume” or “RAID-5 volume”

Note: Redundancy can be provided for both data and operating system volume but the latter supports only “Mirrored Volume”. For more information about using operating system raid solution refer to Microsoft documents
