Product Description
The IBM ENZ0 PCIe Gen4 I/O Expansion Drawer (Feature Code: ENZ0) is a high-performance 4U rack-mount PCIe expansion enclosure designed for IBM Power Systems. This drawer supports up to 18 PCIe Gen4 adapter slots (with appropriate riser configurations), enabling significant I/O scalability for high-bandwidth networking, storage controllers, GPUs, and other PCIe devices in demanding IBM i environments. It provides flexible, hot-plug-capable expansion with redundant power and cooling for enterprise reliability.
Key Features
- 18 PCIe Gen4 Slots: Supports up to 18 full-height, half-length PCIe Gen4 adapters (configuration-dependent).
- PCIe Gen4 Connectivity: Delivers double the bandwidth of Gen3 with low-latency external attach to the host system.
- Hot-Plug Support: Allows adapter addition/replacement without system downtime in supported configurations.
- Redundant Power & Cooling: Dual power supplies and multiple redundant fans for maximum uptime.
- IBM Power Optimized: Fully integrated and qualified for IBM Power Systems running IBM i.
- Scalable I/O Architecture: Ideal for high-throughput networking (e.g., 100GbE), Fibre Channel, and additional NVMe controllers.
- 60-Day Warranty: Includes a 60-day warranty for reliability.
- Feature Code: ENZ0

Compatibility The IBM ENZ0 PCIe Gen4 I/O Expansion Drawer is compatible with IBM Power Systems running IBM i, including Power11 models 9824-22A (Power S1122) and 9824-42A (Power S1124). Power10 models such as 9105-41B (Power S1014), 9105-22A (Power S1022), 9105-22B (Power S1022s), 9105-42A (Power S1024), 9043-MRX (E1050), and 9080-HEX (E1080). It requires appropriate PCIe Gen4 host bridge adapters (e.g., feature codes for external I/O attach) and cabling in the central electronics complex (CEC). The drawer supports IBM i native I/O adapters for networking, storage, and acceleration. Not compatible with systems lacking external PCIe expansion support or Gen3-only configurations without appropriate bridging. The below features are supported in the ENZ0 expansion drawer:
