HPE Smart Array P840 Controller
Overview
HPE Smart Array P840 Controller
The HPE 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
internal physical links and delivers increased server uptime by providing advanced storage functionality, including online RA
level migration between any RAID levels with FBWC, global online spare, and pre
drives without need for the SAS Expander Card providing point to point connectivity to SSDs for lower latency. This controlle

Pre-Failure Warranty: Drives attached to the Smart Array Controller and monitored under Insight
• S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at HPE detects
possible hard disk failure before it occurs, allowing replacement of the component before
failure occurs.
• Drive Parameter Tracking monitors drive operational parameters, predicting failure and
notifying the administrator.
• Dynamic Sector Repairing continually performs background surface scans on the hard disk
drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
• Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure
preventative maintenance.
• Recovery ROM: This feature provides unique redundancy that protects from a ROM image
corruption. A new version of firmware can be flashed to the ROM while the c
revert back to the previous version of firmware and continue operating. This reduces the risk
of flashing firmware to the controller.
• 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 corrects against single bit data and address corruption.
