Overview

The HP Smart Array P411 is HP's PCI Express (PCIe) Serial Attached SCSI (SAS) RAID controller. The low profile, half height card has 8 ports and utilizes DDR2-800 memory. 'The P411 is ideal for RAID 0/1, 5, 1+0 & 5+0 and can be upgraded with the 512MB battery­backed write cache (BBWC) or 512MB/1G Flash Backed Write Cache (FBWC) module and Smart Array Advanced via license key for RAID 6 &, 6 +0.

Native Command Queuing
Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard disk drives by allowing the individual hard disk to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary going back-and-forth on the drive's heads, resulting in increased performance for workloads where multiple simultaneous read/write requests are outstanding, most often occurring in server or storage-type applications. Without NCQ the drive has to process and complete one command at a time. For NCQ to be enabled, it must be supported and turned on in the controller and in the hard drive itself.
NOTE:
Please see the SATA Hard Drive QuickSpecs for specific SATA hard drive capacities that support NCQ:

Fault Prevention
The following features offer detection of possible failures before they occur, allowing preventive action to be taken:
S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology) was first developed by HP which 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. Environment Tracking for External Storage System: Monitors fan speed and cabinet temperature of Modular Smart Array Enclosures and HP Disk Enclosures.

Fault Tolerance
Fault Recovery
Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including:
RAID 6 with ADG
two sets of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand two simultaneous drive failures without downtime or data loss.
RAID 6+0
across the external boxes
NOTE:
RAID 6, 6+0 can be enabled with either
Minimum of 256 MB cache with Battery kit and Smart Array Advanced Pack License key option upgrades Minimum of 512 MB BBWC or FBWC and Smart Array Advanced Pack License key option upgrades
RAID 5
(Distributed Data Guarding): This allocates one set of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand a single drive failure without downtime or data loss.
RAID5 is available on the SA P411 with a minimum of 256MB cache
RAID 5+0
striping of RAID 0 with the distributed parity of RAID 5.
Drive Mirroring
mirrored data, providing two copies of every file. It is a high-performance RAID.
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
(Advanced Data Guarding): This is the highest level of fault tolerance. It allocates
: Supported with min of 8 drives, but would have 4 available. Target benefit is to split RAID
: This is a RAID 0 array striped across 5 elements. Combines the straight block-level
(RAID 1, 1+0): This allocates half of the drive array to data and the other half to
Ease of Use
Recovery ROM: This new feature provides a unique redundancy feature that protects from a ROM image corruption. A new version of firmware can be flashed to the ROM while the controller maintains the last known working version of firmware. If the firmware becomes corrupt, the controller will 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. Battery-backed write cache upgrade provides for up to two days of battery power for data cache retention. The data backup duration could be extended anytime the server's auxiliary power is available during system power down. Flash Backed Write Cache upgrade provides indefinite data retention.
Consistency and Upgradeability make the Smart Array family unique in the industry:
