Product Description
The IBM 9406-5904 is a specialized RAID adapter engineered for IBM's iSeries and AS/400 server platforms, specifically designed to integrate with the 9406 system architecture. This adapter is crucial for managing and protecting data stored on internal drives. It utilizes the Serial Attached SCSI (SAS) interface, operating at 3Gb/s, which provides a robust and high-speed connection for SAS hard drives, known for their reliability and performance in enterprise environments. A key feature of this RAID adapter is its substantial 1.5GB of cache memory. This onboard cache significantly accelerates read and write operations by temporarily storing frequently accessed data and buffering write requests. The cache, combined with advanced RAID algorithms, allows the adapter to support various RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity), RAID 6 (striping with dual parity for enhanced fault tolerance), and RAID 10 (striped mirrors), among others. This ensures both high performance and data availability. The IBM 9406-5904 adapter is designed to provide enterprise-grade data protection and performance enhancement for the storage subsystem of the 9406 system. It likely supports hot-swappable drives, allowing drives to be replaced or added without shutting down the system, further minimizing downtime. This makes it an essential component for businesses relying on the iSeries or AS/400 for critical operations where data integrity and continuous availability are paramount.
