The HPE Smart Array S100i SR Gen10 is a software-based RAID controller embedded directly on the system board of select HPE ProLiant Gen10 servers (e.g., ML30, ML110, DL20, DL120). Unlike hardware RAID controllers (e.g., P408i-a, E208i-p), the S100i offloads RAID processing to the host server’s CPU and uses system memory for cache.

: Offers support for various RAID levels, typically including RAID 0, 1, 10, 5, and 50. This allows for a balance between performance, capacity, and redundancy.

: Integrates with HPE's management tools such as HPE Integrated Lights-Out (iLO) and HPE Smart Storage Administrator (SSA) for monitoring, configuration, and management of the storage subsystem.

The is an embedded, entry-level storage solution designed to provide essential data protection and performance for HPE ProLiant Gen10 servers and Synergy Gen10 compute modules. As an "S-class" controller, it is a software-defined (driver-based) RAID solution that leverages the server's CPU to manage storage operations rather than using dedicated hardware. Key Features and Specifications

The "SR" in S100i SR Gen10 stands for , but practically, it signals NVMe capability .

It is a "Hardware-assisted Software RAID." It retains the hardware form factor but offloads the computational cost to the CPU, which on modern Xeon processors is negligible.
