Product Description
The IBM ENZF PCIe4 6-Slot Fanout Module (Feature Code: ENZF) is a high-performance PCIe Gen4 fanout module designed for installation in the ENZ0 PCIe Gen4 I/O Expansion Drawer. This module provides six full-length, full-height PCIe Gen4 adapter slots (compatible with PCIe Gen1/Gen2/Gen3/Gen4 adapters), enabling expanded I/O connectivity for networking, storage controllers, accelerators, and other high-bandwidth devices in demanding IBM i environments. Up to two ENZF modules can be installed per ENZ0 drawer for a total of 12 slots with superior Gen4 bandwidth and low latency.
Key Features
- 6 PCIe Gen4 Slots: Six full-length/full-height slots per module supporting x16 electrical (configuration-dependent).
- PCIe Gen4 Technology: Double the bandwidth of Gen3 for high-throughput adapters and reduced latency.
- Backward Compatibility: Fully supports PCIe Gen1/Gen2/Gen3 adapters in Gen4 slots.
- Hot-Plug Capable: Enables adapter installation/replacement without downtime in supported configurations.
- IBM Power Optimized: Fully integrated and qualified for use in ENZ0 drawers on IBM Power Systems running IBM i.
- Scalable I/O Expansion: Ideal for adding multiple high-speed NICs, Fibre Channel HBAs, or NVMe controllers.
- 60-Day Warranty: Includes a 60-day warranty for reliability.
- Feature Code: ENZF
Technical Specifications
- Feature Code: ENZF
- Slots per Module: 6 x PCIe Gen4 (full-length/full-height)
- Interface: PCIe Gen4 x16 electrical (per slot, via drawer midplane)
- Compatibility: Backward compatible with PCIe Gen1/Gen2/Gen3 adapters
- Installation: Requires ENZ0 PCIe Gen4 I/O Expansion Drawer; one or two modules per drawer

Compatibility The IBM ENZF PCIe4 6-Slot Fanout Module is compatible with the ENZ0 PCIe Gen4 I/O Expansion Drawer on 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 and cabling in the host system for attachment. The module supports IBM i native I/O adapters for networking, storage, and acceleration (e.g., Ethernet RoCE, Fibre Channel). Up to two ENZF modules per ENZ0 drawer provide 12 total slots. Not compatible with Gen3-only drawers (e.g., EMX0) or systems lacking external PCIe Gen4 expansion support.
