Why Choose Used AS400 Servers?
IBM AS400 systems, now known as the IBM iSeries and Power Systems families, are renowned for their rock-solid reliability and long-term platform stability. These servers continue to power critical operations across finance, logistics, manufacturing, and healthcare industries.
Opting for used AS400 hardware is not just a budget-conscious move; it’s a strategic IT decision. Organizations can maintain compatibility with existing applications, extend system lifecycles, and avoid the complexity of replatforming, all while significantly reducing the total cost of ownership.
Benefits of Choosing Used AS400:
- Retain compatibility with legacy OS/400-based applications
- Minimize downtime and training by keeping proven systems in place
- Avoid unnecessary software reengineering or data migration
- Extend the useful life of capital equipment
- Access discontinued or rare models are no longer available.
Key Considerations When Buying a Used AS400
Before purchasing a used AS400 system, it’s essential to evaluate your current IT environment, software compatibility, and performance requirements. Below are four critical technical factors to help you make a confident, informed decision.
Operating System Compatibility
IBM AS400 systems are designed to run various versions of the OS/400 operating system (now known as IBM i). Not all hardware revisions support all OS versions; for example, older models may only run OS/400 V5R3 or earlier, while newer ones can support IBM i 7.x. Ensure the model you select is compatible with your current OS level and licensing agreements.
Processor Types and Performance
The AS400 family includes systems built on different generations of PowerPC and POWER processors, ranging from 64-bit PowerPC-AS to POWER5 and beyond. Each processor generation varies significantly in performance, energy efficiency, and virtualization capabilities. When evaluating a used AS400, consider the CPU speed, number of cores, and whether the model supports symmetric multiprocessing (SMP) for workload scalability.
Storage Expansion Options
Storage flexibility is a key factor when deploying or upgrading refurbished AS400 systems. Depending on your model, available interfaces may include SCSI, Ultra320, Fibre Channel, or even SSD retrofits. Evaluate your current and future storage needs, including RAID configurations, backup frequency, and growth expectations.
Memory Configuration
Each AS400 server model supports specific memory module types, speed ratings, and maximum capacities, such as DDR or SDRAM modules in designated banks or slots. Memory configuration impacts not only overall performance but also system stability and software compatibility.
