Run (after installing HPE SSACLI):
ssacli controller slot=0 show config
Output should show the S100i controller, RAID level, and physical drive status.
Historically, HPE provided separate driver .exe or .zip packages for download. However, for Windows Server 2022 and the Gen10 platform, the drivers for the S100i are integrated into the HPE Intelligent Provisioning (IP) Recovery Environment. Run (after installing HPE SSACLI): ssacli controller slot=0
Crucial Note: HPE strongly advises against attempting to download individual drivers from the HPE Support Center for the S100i unless specifically directed by a Support Matrix. The most stable and supported method of installation is via the Intelligent Provisioning boot media.
While the S100i is not a high-performance RAID controller, you can optimize it for Windows Server 2022: Output should show the S100i controller, RAID level,
After install:
Fortunately, HPE maintains drivers specifically for the S100i controller under Windows Server 2022. The package typically appears as:
"HPE Smart Array S100i SR Gen10 SW RAID Driver for Windows Server 2022" After install:
After successful driver installation:
Cause: The S100i is in AHCI mode, not RAID mode.
Solution:
The "SR" in "SR Gen10" stands for Software RAID. This distinction is crucial because Windows Server 2022 does not include an inbox driver for the S100i. Without the correct driver, the Windows installer will see zero logical drives, rendering the server useless until the driver is loaded.
