Hpe Smart Array S100i Sr Gen10 Driver Jun 2026

Unlike hardware-based Smart Array controllers (e.g., P408i, E208i), the S100i does not have dedicated onboard processor or cache memory. All RAID calculations (e.g., parity for RAID 5) are performed by the host CPU.

The S100i allows for the installation of the OS directly onto a RAID array (RAID 1 or RAID 10), which is often a limitation of pure software RAID solutions. It supports booting from the array, making it suitable for an "all-in-one" box setup. hpe smart array s100i sr gen10 driver

Because the driver runs on the OS, if the operating system crashes or blue-screens, you lose access to the RAID management logic. While the array remains intact, troubleshooting can be slightly more complex than with a hardware card that operates independently of the OS state. Furthermore, driver support is generally limited to major operating systems (Windows Server, RHEL, SLES, VMware ESXi). If you are running niche hypervisors or older legacy systems, compatibility might be an issue.

For the entry-level ProLiant server market, it strikes a near-perfect balance. It offers better reliability and management features than a standard SATA controller, without inflating the server cost. If your workload is light to moderate and RAID 1/10 meets your redundancy needs, the S100i is an excellent choice. However, for mission-critical or storage-heavy workloads, consider it a placeholder until you can invest in a dedicated hardware RAID adapter.
