HPE Smart Array P408i-a SR Gen10 Controller
The HPE Smart Array P408i-a SR Gen10 Controller, supporting 12Gb/s SAS and PCIe 3.0, is ideal for maximizing performance while supporting advanced RAID levels with 2 GB flash-backed write cache (FBWC). This controller operates in Mixed Mode which combines RAID and HBA operations simultaneously. It has eight internal SAS lanes, allowing connection to SAS or SATA drives, and offers encryption for data-at-rest on any drive with HPE Smart Array SR Secure Encryption. This type-a flexible/modular controller occupies a dedicated storage slot without occupying a PCIe expansion slot and provides enterprise-class storage performance, reliability, security and efficiency needed to address your evolving data storage needs.

Fault Prevention: | The following features offer detection of possible failures before they occur, allowing preventive action to be taken: |
Predictive drive failure detects possible drive failure before it occurs, allowing replacement of the component before failure occurs. | |
Background surface scan checks drives during inactive periods and automatically remaps bad sectors, ensuring data integrity. | |
HPE SmartSSD Wear Gauge reports the amount of lifetime remaining on your SSDs. | |
Fault Recovery: | Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure |
Recovery ROM: This feature protects the user from a firmware image corruption by storing a redundant copy of the firmware image. If the active firmware image becomes corrupt, the controller will use the redundant firmware image and continue operating. | |
On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically. | |
DRAM ECC detects and corrects data bit errors. | |
HPE SSD Smart Path: | The HPE SSD Smart Path feature included in the Smart Array software stack improves Solid State Disk (SSD) read performance by up to 4x. HPE SSD Smart Path chooses the optimum path to the SSD and accelerates reads for all RAID levels and RAID 0 writes. |
