## Long description

The HPE Smart Array P840ar Controller is a 12 Gb/s SAS, PCIe 3.0 x8 RAID controller designed for HPE ProLiant DL360 and DL380 Gen9 rack servers. It offers enterprise-class storage performance, supports up to 16 internal drives without a SAS expander, and provides point-to-point connectivity to SSDs to reduce latency. The controller includes flash-backed write cache (FBWC) and features such as global online spare and pre-failure alert to help maintain data availability.
Advantages
The controller delivers increased internal scalability and higher server uptime through advanced storage functions including online RAID level migration and support for HPE Secure Encryption. By supporting 16 internal physical links without an expander, it provides direct connectivity to drives for lower latency. It also supports the HPE Smart Storage Battery to enable multiple Smart Array controllers to be backed by a single battery.
Key specifications
Interface: 12 Gb/s Serial Attached SCSI (SAS), PCI-Express 3.0 x8
Supported servers: HPE ProLiant DL360 Gen9, DL380 Gen9

How to use
Install the controller in a compatible PCIe 3.0 x8 slot of an HPE ProLiant DL360 or DL380 Gen9 server. Connect internal SAS cables to up to 16 drives directly; no SAS expander is required for 16-drive configurations. Configure RAID levels and cache settings through the server management utility or HPE Smart Storage Administrator. If data protection requires it, install the HPE Smart Storage Battery and enable encryption via HPE Secure Encryption settings.
Recommendations
For optimal performance and reliability, use certified HPE drives and firmware, configure appropriate RAID levels for your workload, and ensure the Smart Storage Battery is installed when FBWC is used to protect cached data. Keep controller firmware and server management utilities up to date.
