Lenovo Flex System CN4054S 4-Port 10Gb SW Upgrade | FCoE, FoD

Activate storage-aware fabric capability for supported Lenovo Flex System environments with this software upgrade option. The Lenovo Flex System CN4054S 4-port 10Gb Virtual Fabric Adapter SW Upgrade (FoD) is designed for teams that need to enable 10 Gbit/s connectivity and FCoE support without changing the underlying adapter class. This upgrade aligns with Flex System PCIe Expansion Node deployments and supports the same 4-port virtual fabric architecture associated with the CN4054S platform. For infrastructure teams, that means a controlled path to expand fabric capability while keeping the hardware footprint consistent across compatible compute nodes. It is a practical fit for environments that value configuration consistency, storage traffic consolidation, and a clean upgrade path inside Lenovo Flex System chassis. Where physical adapter replacement would add cost or operational friction, this FoD model provides a more targeted way to enable the required fabric features.
