Hi Vassiliy,


From the screenshot you provided, I believe you are using embedded raid controller to configure raid.  Unfortunately the embedded controller is not support by ESXi, so the installation won’t be able to see the raid volume that you created with this controller. In this case you will need to use a PCI or mezzanine base controller for the installation.

Supported Mezzanine and PCI controllers

Manuel, thank for you answer.


I don't undestand where in BIOS  I can choose not Embedded controller. See first screenshot. Its all I have to choose.


If I choose Disable Onboard SCU Storage Support (as it is written in datasheet) for using PCI controller, server doesn't see physical drives.



Thank you

The embedded controller is a piece of hardware (embedded) to the motherboard of his server to disable the embedded controller in the bios you will need to disable the option Onboard SCU Storage Support.  


If you remove the top cover of your server you will notice that the SAS cables are connected to two SAS port on the motherboard.  For this installation to work you need a PCI or Mezzanine base controller

Hi Vassiliy,


From the screenshot it looks like you that you don't have another PCI base raid controller. You will need to buy one and installed on this server.  When you get the new controller, you can connect sas cables to the new controller.
