Product Description
The IBM 22R4275 is a high-performance RAID controller card engineered to augment the capabilities of the IBM DS4800 storage system. Featuring 2GB of cache memory, this controller significantly accelerates data read and write operations by buffering frequently accessed data. This cache acts as a high-speed intermediary between the host system and the disk drives, reducing latency and improving overall storage throughput, which is critical for demanding enterprise workloads. Beyond caching, the 22R4275 provides robust RAID (Redundant Array of Independent Disks) functionality. It supports various RAID levels, such as RAID 0, 1, 5, 6, 10, 50, and 60, allowing administrators to configure disk arrays for optimal balance between performance, data redundancy, and capacity. This ensures data integrity and availability, protecting against data loss due to individual drive failures. The '82A' designation likely refers to a specific revision or feature set of this controller. This controller card is a vital component for ensuring the reliability and performance of the DS4800 storage solution. Its advanced processing capabilities and ample cache allow the DS4800 to handle complex storage tasks efficiently, making it suitable for applications requiring high I/O rates and continuous data access. The 22R4275 is designed for seamless integration into the DS4800 chassis, providing a scalable and resilient storage platform.
