Product Description
The IBM 2624 Internal SCSI Storage Device Controller (Feature Code: 2624) is a robust Input/Output Processor (IOP) for IBM AS/400 systems. This controller ensures reliable server storage connectivity for enterprises.
Technical Specifications
The IBM 2624 Internal SCSI Storage Device Controller is designed to manage up to three internal SCSI tape or CD-ROM devices and one external diskette device when paired with the #6146 Diskette Adapter. It’s a critical component for AS/400 systems, particularly in migration scenarios requiring diskette or CD-ROM support. The 2624 is not primarily specified for tape control but can manage supported tape devices if already installed or specified for diskette/CD-ROM. It requires specific slot placement in expansion towers for optimal performance, with one SPD I/O card slot used. The controller supports a variety of internal SCSI devices, ensuring flexibility for legacy environments. Its design excludes concurrent maintenance for tape or CD-ROM in certain configurations, reflecting its focus on older AS/400 infrastructure. Available refurbished, the 2624 comes with a 90-day warranty, making it a cost-effective solution for maintaining legacy systems.

- Supported Systems: AS/400 9406 models, expansion towers (5072, 5073, 5077, 5064, 9364)
The #6146 Diskette Adapter enables external diskette control without reducing the 2624’s capacity for internal SCSI devices. When used solely for diskette control, the 2624 is not considered a high-workload IOP, offering flexibility in slot placement. For tape or CD-ROM control, it must be installed in designated slots (e.g., slot 3 of 5072/5073 or slot 4 of 5077) due to hardware constraints. The 2624 does not support concurrent maintenance for tape or CD-ROM in 503X Migration Tower I or 5064/9364 System Unit Expansion, limiting its use in those configurations. In migration scenarios, the 2624 is specified when diskette or CD-ROM is required, but tape control defaults to the #6513 Internal Tape Device Controller unless a 2624 is already present. This ensures efficient resource allocation during system upgrades.
System Compatibility
The 2624 controller requires specific slot placement and OS/400 in AS/400 systems for high-performance server storage operations.
- Supported Systems:
- AS/400 9406 models
- Expansion Towers: 5072, 5073 (slots 3–10), 5077 Migration Tower II (slot 4), 5064/9364 with #9331 (any slot for diskette)
- Operating System: OS/400 V4R4+.
- Requirements: Internal SCSI interface, #6146 for diskette control, designated slots for tape/CD-ROM.
- Restrictions:
- Compatible with legacy AS/400 systems only.
- Incompatible with Power Systems, Storwize.
- No concurrent maintenance in 503X or 5064/9364 for tape/CD-ROM.
- Refurbished condition only.
The 2624’s design prioritizes legacy AS/400 environments, offering a balance of flexibility and performance for managing internal and external storage devices in enterprise settings.
