    The HP Smart Array P841 Controller is a full height, PCIe3 x8, 12Gb/s Serial Attached SCSI (SAS) RAID controller that provides enterprise-class storage performance, increased external scalability, and data protection for select HP ProLiant Gen9 rack and tower servers. It features sixteen external physical links and delivers increased server uptime by providing advanced storage functionality, including online RAID level migration (between any RAID levels) with 4GB flash back write cache (FBWC), global online spare, and pre-failure warning. This controller includes transportable FBWC allowing the data in the cache to be migrated to a new controller.

    The Gen9 family of controllers supports the HP Smart Storage Battery. With HP Smart Storage Battery, multiple Smart Array controllers are supported without needing additional backup power sources for each controller, resulting in simple upgrade process

    • The SA-P841 Controller supports up to 200 physical drives
    • Direct Attached Support for 12Gb/s HP D3600 Disk Enclosure and HP D3700 Disk Enclosure (up to 8 daisy chained in dual domain configuration). Seamless upgrades to current or next generation HP high performance and high capacity Serial Attached SCSI Smart Array controllers.
    • 12Gb/s SAS technology delivers high performance and data bandwidth and contains full compatibility with 6Gb/s SATA technology
    • Direct Attached Support for 6Gb/s HP D6000 JBOD
    • PCI Express Gen3 x8 link width delivers high performance and data bandwidth up to 8GT/s theoretical maximum bandwidth
    • 4 GiBytes Flash Backed Write Cache kit  (FBWC) provides read ahead caching and write back caching with indefinite write cache data retention in the case of unexpected power outage
    • Supports legacy and UEFI boot operation on Gen9 servers
    • Standard on the P841 are RAID 6, RAID 60, RAID 1 ADM, Capacity Expansion, mirror split, recombine, and rollback in Online Mode, Drive Erase, Performance Optimization-Degraded Reads and Read Coalescing, Move/Delete any individual LUNS
    • The HP SSD Smart Path feature included in the Smart Array software stack improves SSD reads for all RAID levels and RAID 0 write operations by optimizing the path to each SSD attached to the controller
    • The HP SmartCache feature (HP Smart Cache license is not required on P841) is a controller-based read and write caching solution in a DAS environment that caches the most frequently accessed data ("hot" data) onto lower latency SSDs to dynamically accelerate application workloads
    • Optional HP Secure Encryption is a Smart Array controller-based data encryption solution for ProLiant Gen9 servers that protects sensitive, mission critical data.
    • Mix-and-match SAS and SATA hard drives lets you deploy drive technology as needed to fit your computing environment
    • Support for SAS tape products
    • Software consistency on most current shipping Smart Array products: HP Smart Storage Administrator (HP SSA), HP Systems Insight Manager, and HP Intelligent Provisioning. The HP Smart Storage Administrator configures and manages a host of Smart Array controllers and other storage devices using a single interface. It replaces the HP Array Configuration Utility (ACU) with an updated design and configuration enhancements.
