LENOVO - 01KR603 - Emulex VFA5.2 2x10 GbE SFP+ PCIe Adapter

Product Overview

The LENOVO 01KR603 Emulex VFA5.2 is a dual-port 10GbE SFP+ PCIe network adapter built for high-throughput server connectivity in enterprise and data center environments. With 2x 10GbE SFP+ interfaces and a PCIe host connection, it is a practical upgrade path when you need consistent bandwidth for virtualisation hosts, storage networks, and east-west application traffic.

This adapter is commonly deployed in supported Lenovo server platforms with available PCIe expansion, including ThinkSystem and System x rack configurations. For platform sourcing and part matching across Lenovo estates, see LENOVO options, and for validated host platforms consider the RACK SERVER category.

In a typical top-of-rack design, the SFP+ ports connect upstream to a 10GbE aggregation layer using optical transceivers or direct-attach cabling; for compatible upstream connectivity, pair with a Lenovo SWITCH. If your Lenovo platform uses modular I/O, you may also standardise connectivity via a NETWORK MODULE depending on chassis support.

Key Features

Key technical characteristics for integrating the 01KR603 into server builds and refresh projects:

• 2x 10GbE SFP+ network ports to provide high-bandwidth fiber or DAC-based server uplinks.
• PCIe adapter form factor to add 10GbE connectivity to compatible Lenovo servers with available PCIe slots.
• Emulex VFA5.2 controller architecture to support stable enterprise Ethernet connectivity in virtualised environments.
• Compatibility with Lenovo ThinkSystem and System x families (examples include ThinkSystem SR series and System x rack platforms) to simplify part matching in mixed Lenovo estates.
• Support for standard Ethernet networking features (driver/OS dependent) to integrate into segmented networks and controlled access designs.
• Designed for data center 24/7 operation to provide reliable connectivity for production workloads.
• SFP+ media flexibility to support optical transceivers or direct-attach cabling based on rack layout and distance requirements.
• Suitable for server uplinks carrying VM, management, and storage-related traffic to consolidate workloads on 10GbE links.

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 components are a practical choice for extending the lifecycle of existing Lenovo environments, reducing electronic waste, and controlling budget compared to buying new.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a 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.
