Description

The IBM 42R8739 is a high-performance RAID controller designed to leverage the speed and efficiency of the PCI Express interface. It supports Ultra320 SCSI, enabling data transfer rates of up to 320 MB/s per channel, making it suitable for demanding enterprise applications that require fast and reliable storage access. This controller offers a comprehensive set of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, providing users with the flexibility to configure storage arrays for optimal performance, data redundancy, or a combination of both. The controller features versatile connectivity options with one internal SFF-8484 connector, capable of supporting up to four drives, and one external SFF-8470 connector, also supporting up to four drives. This dual-port design allows for flexible storage configurations, enabling both internal drive management and external storage expansion. The PCI Express interface ensures high bandwidth communication with the host system, minimizing bottlenecks and maximizing I/O performance. Equipped with 128MB of DDR ECC (Error-Correcting Code) SDRAM cache, the IBM 42R8739 accelerates read and write operations by buffering data, thereby reducing latency and improving overall system responsiveness. The ECC memory is crucial for maintaining data integrity in mission-critical environments by detecting and correcting memory errors. Powered by a reliable LSI Logic chipset, this RAID controller is a robust solution for businesses seeking to enhance their storage infrastructure with advanced features and high performance.
