Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard diskdrives by allowing the individual hard disk to internally optimize the order in which received read and write commands are executed |
Given the increasing need for high performance and rapid capacity expansion, the SA-P420 Controller offers: |
Provides increased server uptime by providing advanced storage functionality: Online RAID level migration between any RAID levels (With FBWC ) Online stripe size migration Online capacity expansion Online logical drive extension Online active drive replacement Online drive firmware upgrade Unlimited global online spare Pre-Failure warranty

The following features offer detection of possible failures before they occur, allowing preventive action to be taken: Self Monitoring Analysis and Reporting Technology (SMART) first developed at HPE detectspossible hard disk failure before it occurs, allowing replacement of the hard drive before a realfailure occurs Drive parameter tracking monitors drive operational parameters, predicting failure andnotifying 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 protects the user from a firmware image corruption by storing are dundant copy of the firmware image. If the active firmware image becomes corrupt, the controller will use the redundant firmware image and continue operating 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 detects and corrects data bit errors 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 Battery-backed write cache upgrade

The HPE SmartCache licensed feature is a controller-based read caching solution in a DAS environment that caches the most frequently accessed data (Hot Data) onto lower latency SSDs to dynamically accelerate application work loads Bulk storage: The first element is the bulk storage device, which is any supported HDD attached to the HPE Smart Array controller Accelerator: The second element, the accelerator, is a faster/lower latency SSD device that caches data Metadata: The final element is metadata, information held in a relatively small storage areathat maps the location of information residing on the accelerator and bulk storage devices
