HPE 804326-B21 Smart Array E208i-a SR Gen10 SAS Controller

Overview

The HPE Smart Array E208i-a SR Gen10 (804326-B21) is a Gen10-generation SAS storage controller engineered for HPE ProLiant DL3x0 and ML350 Gen10 server platforms. Designed as an internal, modular controller, it provides SAS connectivity for attaching drives directly to Gen10 ProLiant infrastructure — giving architects a path to structured local storage without adding external HBAs or expansion shelves.

If your deployment requires a storage controller that integrates cleanly with HPE's Gen10 server management stack and ProLiant tooling, the 804326-B21 (often searched as 804326 B21) is the generation-matched option for DL3x0 and ML350 server builds.

Key Features

• Gen10 Platform Integration: Designed and validated for HPE ProLiant DL3x0 and ML350 Gen10 servers, meaning it slots into the correct mechanical bay and communicates with iLO and Smart Storage Administrator without driver workarounds or compatibility flags.
• SAS Interface: SAS connectivity supports both SAS and SATA drive types, giving you flexibility to mix drive tiers within the same controller — useful when tiering between SSD and spinning disk in a single chassis.
• Smart Array Architecture: As part of HPE's Smart Array family, the E208i-a is managed through HPE's Smart Storage Administrator (SSA) toolset, which integrates with HPE iLO for health monitoring, predictive failure alerting, and firmware lifecycle management without requiring separate management software licenses.
• Internal Form Factor: The
