RAID Cards for IBM AS/400 Systems

IBM RAID cards for AS/400 (System i / iSeries) systems deliver dependable storage management with RAID capabilities designed for the AS/400 and early Power-based IBM i platforms. These adapters (primarily SCSI-based with some later SAS models) support RAID levels including RAID 0, 5, 6, 10, and mirroring, providing essential data protection, redundancy, and performance for legacy enterprise environments.

With select models featuring integrated cache (for improved write performance), hot-swap support, and compatibility with internal/external SCSI/SAS/SATA drives (primarily HDDs), these cards enable flexible disk expansion and high-availability configurations. They integrate seamlessly with AS/400 and IBM i operating systems (OS/400, i5/OS, IBM i), supporting system-level mirroring and RAID-protected disk arrays.

Common legacy models include SCSI RAID adapters (e.g., feature codes 5700, 5701, 5708, 5720, 573A, 573B) and early SAS RAID variants (e.g., 573C, 5740), offering 3 Gb/s or 6 Gb/s connectivity suited to AS/400 and early Power5/Power6 slots. These cards are suitable for databases, ERP systems, and other workloads requiring reliable storage on aging AS/400 infrastructure.

IBM AS/400 RAID cards are backed by a 60-day warranty, ensuring quality and dependable performance for legacy systems.

Key Features

  • Support for RAID levels 0, 5, 6, 10, and mirroring.
  • Optional integrated cache (on select models) for improved write performance.
  • High-availability configurations and system-level redundancy support.
  • SCSI or early SAS interface (3 Gb/s or 6 Gb/s).
  • Hot-swap capable (on supported models) for reduced disruption during maintenance.
  • Compatibility with SCSI/SAS/SATA HDDs (primarily legacy drives).
  • Optimized for AS/400 and early IBM i systems.
  • Redundant power and component support in system integration.
