LENOVO - 01CV792 - Flex System CN4054S 4-port 10GB Virtual Fabric

Product Overview

The Lenovo 01CV792 Flex System CN4054S is a 4-port 10Gb Virtual Fabric network adapter built for Lenovo Flex System environments, providing 10Gb Ethernet connectivity with Virtual Fabric capabilities for consolidated I/O. It is designed to support segmented enterprise networks using standard features such as VLANs and QoS, helping you separate traffic types and maintain predictable performance on shared links.

Common deployment scenarios include Flex System chassis used for virtualisation clusters, private cloud, and dense data center compute where reducing adapter count and simplifying cabling are priorities. For end-to-end integration, it is typically paired with upstream SWITCH infrastructure and chassis I/O options such as a NETWORK MODULE, depending on the Flex System architecture.

Compatibility: this adapter is intended for Lenovo Flex System compute nodes and I/O designs where CN4054S support is required, including examples such as Flex System x240, x440, and x480 class nodes. It can also be used as part of a broader Lenovo estate alongside related RACK SERVER deployments that standardise on 10Gb Ethernet at the access layer.

Key Features

Key technical highlights for integration into Lenovo Flex System networking designs:

• 4-port 10Gb Ethernet connectivity to provide high-bandwidth links for virtualised hosts and converged workloads.
• Virtual Fabric capability to support logical network segmentation over fewer physical adapters for simplified I/O design.
• VLAN support to separate tenant, application, storage, and management traffic within the same physical infrastructure.
• QoS features to prioritise latency-sensitive flows (for example voice/video or critical application traffic) on shared links.
• Lenovo Flex System form factor and platform alignment to fit supported chassis and compute node families (e.g., Flex System x240/x440/x480).
• 10Gb adapter architecture to reduce bottlenecks compared to 1Gb designs in dense virtualisation environments.
• Enterprise NIC security controls to help enforce network policy and controlled access at the server edge.
• Built for continuous 24/7 operation to support data center and service-provider workloads.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished parts are a practical way to extend the lifecycle of existing Lenovo Flex System installations, reduce electronic waste, and control budget compared to buying new.

All products from Direct Hardware Supply include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries: three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware, shipping worldwide from Denmark, with sourcing support across LENOVO platforms.
