## Long description

The HPE Smart Array P408i-a SR Gen10 Controller (MPN 804331R-B21) is an enterprise-class RAID controller designed to deliver high storage performance and capacity without using a PCIe expansion slot. It supports 12 Gb/s SAS and PCIe 3.0, provides eight internal SAS lanes for SAS or SATA drives, and includes 2 GB Flash-Backed Write Cache (FBWC). The controller can operate in Mixed Mode (RAID and HBA simultaneously) and offers optional data-at-rest encryption and SmartSSD monitoring features. This type-a modular controller occupies a dedicated storage slot on HPE ProLiant Gen10 servers and is compatible with the HPE Smart Storage Battery (sold separately).
Advantages
The controller increases throughput and reduces latency for messaging, database and general server workloads by providing 12 Gb/s SAS connectivity and 2 GB FBWC. It supports accelerated SSD access with HPE SSD Smart Path and optional SmartCache to cache hot HDD data onto SSDs. Built-in features include optional secure encryption for drives, SmartSSD wear monitoring to help preserve data integrity, and Mixed Mode flexibility to run RAID and HBA concurrently. Management and configuration are simplified through UEFI storage tools and the HPE Smart Storage Administrator.
Suitable for
 Enterprise servers requiring high-performance internal storage (HPE ProLiant Gen10)
 Database and messaging applications with heavy write or logging demands
 Mixed SSD/HDD environments where caching or fast SSD paths improve I/O
 Deployments needing encryption of data-at-rest and drive health monitoring
