The Lenovo 4XC7A76525 is an integrated Fibre Channel Host Bus Adapter (HBA) for servers, connected via a PCI Express interface. It serves to connect servers with Fibre Channel storage systems in SAN environments and enables a maximum data transfer rate of 32000 Mbit/s. The component is designed for use in ThinkSystem server models and supports Hot-Plug, allowing installation or removal during operation without requiring a system restart. The color scheme includes Black, Green, and Stainless Steel, with the exact configuration varying depending on the server model.

Applications

The adapter is designed for applications requiring high data transfer rates and reliability, such as virtualized environments, data backups, or critical business applications. It is used in servers from the Lenovo ThinkSystem series, including models SR630, SR650, SR635, SR655, SR850, SR860, and SR950, with specific model numbers (e.g. 7X01, 7X02, 7X05, 7X06, etc.) listed in the datasheet. Use in SAN infrastructures enables an efficient and redundant storage access solution.

Features and Specifications in Detail

The adapter features two fiber connections equipped with SFP+ optical cable connectors. This interface allows flexible cabling with corresponding transceiver modules. The PCI Express interface is designed for version 4.0, ensuring high bandwidth and compatibility with modern server platforms. The Hot-Plug functionality supports server maintenance and expansion without interrupting operations.

Technology Explained Simply

The maximum data transfer rate of 32000 Mbit/s corresponds to a bandwidth of 32 Gbit/s, sufficient for fast access to storage systems in enterprise environments. The fiber connections use SFP+ technology, enabling high data rates with low latency. The PCI Express 4.0 interface provides sufficient bandwidth to fully utilize the fiber channels. The component is designed for use in servers requiring high performance and reliability.

Compatibility and Accessories

The adapter is compatible with various operating systems, including Red Hat Enterprise Linux 7.6, 7.7, and 8.0, VMware vSphere Hypervisor (ESXi) 6.7 U1, U2, and U3, SUSE Linux Enterprise Server 12, Windows Server 2016, and Windows Server 2019. Compatibility with the specified ThinkSystem server models is confirmed by the manufacturer.

Installation and Mounting

The adapter is installed into a free PCI Express slot in the server. The Hot-Plug functionality allows installation or removal during operation, provided the server supports it. Mounting requires no additional tools, as the component is inserted into the slot and mechanically secured. The electrical connection is made via the PCI Express interface.

Operational Advantages

The high data transfer rate of 32 Gbit/s enables fast and efficient communication between server and storage system. The Hot-Plug functionality reduces downtime during maintenance. Support for multiple operating systems and server models increases flexibility in system planning. Certifications according to various international standards (e.g. CE, FCC, RoHS) ensure compliance with safety and environmental standards.
