Description

The IBM 21P3735, also identified by its system model 2778, is a hardware RAID controller card designed for use in IBM server environments that utilize Ultra2 SCSI storage devices. This controller card provides essential functionality for managing multiple SCSI hard drives, enabling the implementation of RAID configurations to enhance both data protection and storage performance. The 68-pin connector is standard for Wide Ultra2 SCSI connections, allowing for high-speed communication with compatible drives. This controller card supports several RAID levels, including RAID 0 for striping data across drives to improve performance, RAID 1 for mirroring data for redundancy, RAID 5 for striping with parity for a balance of performance and protection, and RAID 10 (RAID 1+0) for combined striping and mirroring. By offloading RAID calculations to dedicated hardware, it frees up the server's CPU resources, leading to improved overall system responsiveness, particularly in I/O-intensive applications. Designed for integration into older IBM server architectures via the PCI bus, the 21P3735 is a crucial component for maintaining or upgrading the storage subsystem of legacy systems. It ensures data integrity by providing fault tolerance against single or multiple drive failures (depending on the RAID level configured), making it a valuable asset for businesses that rely on the continued operation of their SCSI-based storage infrastructure.
