A Peripheral Element Interconnect Categorical (PCIe) RAID Controller card, sometimes shortened in widespread parlance, is a {hardware} part employed to handle and management knowledge storage units inside a pc system. It acts as an middleman between the central processing unit (CPU) and storage models, resembling onerous disk drives (HDDs) or solid-state drives (SSDs), enabling refined knowledge administration methods like RAID (Redundant Array of Impartial Disks). As an illustration, a server would possibly make the most of one to configure a RAID 5 array for knowledge redundancy and efficiency enhancement.
These playing cards are essential for programs requiring excessive availability, knowledge safety, and improved enter/output (I/O) efficiency. The benefits embody hardware-based RAID processing, which offloads the RAID calculations from the CPU, main to higher general system efficiency. Additionally they typically supply superior options resembling hot-swappable drive help, distant administration capabilities, and battery backup models (BBUs) to guard knowledge in case of energy loss. The event of those playing cards has developed considerably alongside developments in storage expertise and the growing demand for sturdy knowledge administration options.
