## Long description

The HPE Smart Array E208i‑p SR Gen10 controller (HPE 804394R‑B21) is a PCIe 3.0, 12 Gb/s SAS RAID controller designed for internal attached drives in HPE ProLiant Gen10 servers (including DL360, DL380, DL560). It supports RAID levels 0, 1, 5 and 10, provides eight internal SAS lanes for SAS and SATA drives, and occupies a PCIe expansion slot. The controller supports Mixed Mode (RAID and HBA simultaneously) and offers optional Smart Array SR Secure Encryption to protect data at rest.
Advantages
The controller delivers enterprise-class reliability with 12 Gb/s SAS connectivity while remaining cost-effective for software-defined storage deployments. Built‑in features such as Mixed Mode operation simplify infrastructure by avoiding additional controllers, and integration with HPE management tools (UEFI storage configuration tool and HPE Smart Storage Administrator) enables quick configuration and drive management. Optional encryption and SmartSSD Wear Gauge support improve data protection and integrity monitoring.
Suitable for
Internal storage expansion in HPE ProLiant Gen10 servers (DL360, DL380, DL560)
Small to medium enterprise RAID volumes using SAS or SATA drives
Software-defined storage setups that require cost‑effective SAS connectivity
Environments needing data‑at‑rest encryption compliance (with optional license)
