Product Description
The IBM 81Y4447 ServeRAID controller is a dedicated solution for managing Serial ATA (SATA) storage devices within IBM System x servers. It supports the SATA/600 standard, which provides a data transfer rate of up to 6Gb/s per drive, ensuring efficient performance for modern SATA hard drives and SSDs. The card connects to the server's motherboard via a PCI Express 3.0 x8 interface, offering substantial bandwidth to prevent bottlenecks and maximize storage throughput. This controller is designed to implement RAID (Redundant Array of Independent Disks) configurations, specifically supporting RAID 0, RAID 1, and RAID 10. RAID 0 offers performance gains through striping, while RAID 1 provides data redundancy via mirroring. RAID 10 combines both striping and mirroring for an optimal balance of performance and data protection. These features are crucial for ensuring data availability and integrity in server environments. The IBM 81Y4447 is an internal adapter card, intended for installation within the server chassis to connect directly to SATA drives. It represents a reliable and cost-effective way to enhance a server's storage capabilities, providing essential RAID functionality for businesses that require improved data management, fault tolerance, and performance from their SATA storage subsystems.
