Boot the server into Recovery Mode or Command Prompt via installation media, load the HPE S100i driver via drvload , and use dism to inject the official HPE storage driver package back into the offline Windows image. 3. Poor Write/Read Storage Performance
functions as an entry-level, 6Gb/s SATA software RAID controller embedded directly onto the motherboard of HPE ProLiant Gen10 servers and Synergy compute modules.
The is a small but critical piece of software that unlocks the full potential of software RAID on HPE ProLiant Gen10 servers. While the driver installation process may seem daunting—especially during a clean OS deployment where storage is invisible—following the steps outlined in this guide ensures a smooth, reliable outcome.
Compare the of the S100i versus a hardware controller (P408i).
The S100i controller operates strictly in UEFI boot mode. Legacy BIOS mode is not supported for software RAID configurations. Driver Prerequisites for Windows Server 2022 Boot the server into Recovery Mode or Command
| Feature | S100i (SW RAID) | P408i (HW RAID) | E208i (HW RAID) | |---------|----------------|----------------|------------------| | Processor | Host CPU | ROC (RAID-on-Chip) | ROC | | Cache Memory | None | 2GB FBWC | None / 1GB | | RAID Levels | 0,1,5,10 | 0,1,5,6,10,50,60 | 0,1,5,10 | | Performance | Low to Medium | High | Medium | | Driver Needed in Win2022 | | Optional (in-box drivers exist) | Optional | | Use Case | Boot, low-I/O file shares | Databases, VDI, critical VMs | Light enterprise |
A Windows Update may have overwritten the proprietary HPE storage driver with a generic Microsoft storage controller driver.
: Computational workflows (such as parity calculations for RAID 5) are managed directly by the system's host CPU rather than a dedicated on-board ASIC processor found in P-series hardware controllers. 1. Preparing the Deployment Infrastructure Enable Smart Array SW RAID in System ROM
: The Windows setup wizard will show an empty drive selection screen. The is a small but critical piece of
The download is typically an .exe file (e.g., cp052316.exe ). Crucial Step: You must run this file on a separate PC and select the Extract option to get the actual .inf and .sys driver files. Step-by-Step Installation Guide 1. Enable SW RAID in BIOS
: Operates exclusively in UEFI Boot Mode ; it is not supported in Legacy BIOS Mode.

The HPE Smart Array S100i SR Gen10 software RAID driver for Windows Server 2022 is designed to provide seamless integration with the operating system. The driver allows administrators to manage RAID configurations and monitor disk health from within Windows Server 2022. The S100i controller operates strictly in UEFI boot mode
If the Windows Installer does not see your drives, you need to load the driver during the installation process.
Double-click the downloaded HPE executable on a separate technician computer running Windows. Select the option rather than "Install".
