The HP Smart Array P840 Controller is a full height, PCIe3 x8, 12Gb/s SAS RAID controller that provides enterprise-class storage performance, increased internal scalability, and data protection for HP ProLiant Gen9 rack and tower servers. It features 16 internal physical links and delivers increased server uptime by providing advanced storage functionality, including online RAID level migration between any RAID levels with FBWC, global online spare, and pre-failure warning. This controller supports 16 drives without need for the SAS Expander Card providing point to point connectivity to SSDs for lower latency. This controller has transportable FBWC allowing the data in the cache to be migrated to a new controller.
The Gen9 controllers support the HP Smart Storage Battery that allows multiple Smart Array controllers to be supported, resulting in simple upgrade process.
The P840 Controller supports up to 16 drives without need for expander card. For example, DL38x Gen9 server that comes standard with 8 SFF drives cage can be expanded to additional 8 SFF drive cage connected to Smart Array P840
Seamless upgrades to and from other HP Smart Array controllers.
16 SAS/SATA physical links distributed across 2 double wide Mini SAS 8i connectors for attachment to internal drive backplanes
12Gb/s SAS performance when used on Gen9 servers with 12Gb/s devices (HDD or SSD)
12Gb/s SAS technology delivers up to 1200 MB/s per physical link.
6Gb/s SATA technology delivers up to 600 MB/s for directly attached SATA drives
Mix-and-match SAS and SATA drives. Deploy drive technology as needed to fit the computing environment.
PCI-e 3.0 8x host interface provides up to 8GiB/s in each direction
4GB transportable Flash-backed write cache (not all of which is available for user data)
Standard on the P840 are RAID 6 ADG, RAID 60 ADG, 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 and Online Split Mirror.
Capable of supporting both legacy and UEFI boot operation on Gen9 servers
Recovery ROM protects against ROM corruption
The HP SSD Smart Path feature included in the Smart Array software stack improves SSD read for all RAID levels and RAID 0 write operations by optimizing the path to each SSD attached to the controller.
The HP SmartCache feature (already included with the P840 controller) 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.
The HP Secure Encryption, available as an option, is a Smart Array controller-based data encryption solution for ProLiant Gen9 servers that protect sensitive, mission critical data.
