Hi oufkir

Please refer to SR50 product guide. Even you did not purchase a RAID adapter, there is still an Onboard AHCI (non-RAID) / Intel RSTe (RAID) controller

You can refer to the #Internal storage for detail backplane and drive bay configuration.

Please feel free to leave your comment, thank you for support Lenovo

Hi Sir,


What kind of internal drive bay configuration did you order for the system? You should follow the drive bay configuration to install HDD.

Although you don't need RAID function, but you still need to install non-RAID HBAs controllers for internal storage and SAS adapters for external storage.

For the cable configuration, you can refer to the ThinkSystem SR550 documentation section Internal cable routing for more information.

      Please pay attention that, for the onboard RAID configuration, it only supports 6Gb SATA non hot-swap drives.

      You can refer to the following link for details:
