Product Description
The LSI H3-25412-00K is a high-performance RAID controller card built on the PCI Express 3.0 interface, providing significantly increased bandwidth compared to previous generations. This enables faster data transfers and improved performance for storage-intensive applications. The controller is designed to work with Serial ATA/600 (SATA 6Gb/s) drives, offering support for modern high-speed SSDs and HDDs. Its primary function is to provide advanced data protection and performance enhancement through various RAID configurations. This controller supports a comprehensive range of RAID levels, including RAID 0 for maximum performance, RAID 1 for mirroring and redundancy, RAID 10 for a combination of performance and redundancy, RAID 5 for balanced performance and data protection with parity, and RAID 50 for striping across multiple RAID 5 sets. The inclusion of an onboard RAID-on-Chip (ROC) processor offloads complex RAID calculations from the host CPU, ensuring efficient system performance even under heavy I/O loads. It typically features multiple internal SATA ports for direct drive connections. The LSI H3-25412-00K is engineered for enterprise environments where data integrity, performance, and reliability are critical. It often includes support for an optional Battery Backup Unit (BBU) for the onboard cache memory. The BBU protects cached data during power failures, preventing data loss and ensuring that write operations are completed safely. This makes the controller a robust solution for servers hosting critical databases, file servers, and other applications demanding high availability and data security.
