## Long description

The HPE Smart Array E208e-p SR Gen10 Controller (Peripheral Controller HP Enterprise HPE 804398-B21) is an enterprise-class PCIe expansion controller that provides 12 Gb/s SAS connectivity for externally attached drives. It supports RAID levels 0, 1, 5 and 10, mixed RAID/HBA operation, and optional data-at-rest encryption, enabling cost-effective storage configurations for HPE ProLiant Gen10 servers and external disk enclosures.
Advantages
This controller delivers 12 Gb/s SAS performance over a PCI Express 3.0 x8 host interface, offering a low-cost path to software-defined storage and external JBOD or advanced array connectivity. Mixed Mode allows simultaneous RAID and HBA operation to reduce the need for additional controllers. Optional HPE Smart Array SR Secure Encryption protects data-at-rest on attached drives, while HPE SmartSSD Wear Gauge helps preserve data integrity by warning of potential drive issues.
Suitable for
Connecting external SAS or SATA drives in JBOD enclosures
Implementing basic RAID (0, 1, 5, 10) for servers
Enabling software-defined storage solutions
Deployments requiring data-at-rest encryption on external drives
