The Smart Array S100i is an SATA Software RAID controller embedded into the HPE ProLiant Gen10 server platform (e.g., DL360 Gen10, DL380 Gen10, ML350 Gen10). The "SW" designation stands for "Software," meaning it has no dedicated RAID processor or cache memory. Instead, it uses system CPU cycles and memory to perform RAID calculations.
Expand Storage Controllers. You should see: "HPE Smart Array S100i SR Gen10 SW RAID Controller" with no yellow exclamation marks. The Smart Array S100i is an SATA Software
If your boot drive is connected to the S100i controller, Windows Setup will not see the drive without the driver. Install HPE SSA CLI or GUI: ssacli controller all show
Run a simple disk benchmark (e.g., winsat disk -drive c). Software RAID performance is typically 10-20% slower than hardware RAID, but you should see sequential speeds expected for SATA SSDs/HDDs. Output should list: Smart Array S100i SR Gen10
Install HPE SSA CLI or GUI:
ssacli controller all show
Output should list:
