The Lenovo 4XC7A76498 is an integrated Fibre Channel Host Bus Adapter (HBA) for servers, connected via a PCI Express interface. It enables the connection of servers to Fibre Channel storage systems in SAN environments and supports a maximum data transfer rate of 32000 Mbit/s. The interface is based on fibre optic cables with SFP+ optics, ensuring high bandwidth and stability for data transmission. The adapter is designed for use in professional server environments, particularly in virtualized systems, data backup, and critical applications requiring high storage performance.

Applications

The adapter is specifically intended for Lenovo ThinkSystem servers, including models SR630, SR650, SR635, SR655, SR850, SR860, and SR950. It is used in environments where a reliable and fast connection between server and storage system is required, such as in data centres, high-availability solutions, or managing large data volumes. Support for Hot-Plug allows for easy installation and maintenance without server downtime.

Features and Specifications in Detail

The Lenovo 4XC7A76498 features a single fibre optic connection with SFP+ connector, enabling the use of various optical cable types. The PCI Express interface complies with version 4.0, ensuring high bandwidth and compatibility with modern server platforms. The maximum data transfer rate of 32000 Mbit/s corresponds to 32 Gbit/s and is designed for demanding storage applications. The adapter's colour scheme includes black, green, and stainless steel, indicating its use in various server models.

Technology Explained Simply

Fibre Channel is a high-speed networking technology primarily used to connect servers to storage systems in SANs (Storage Area Networks). The adapter acts as a bridge between the server and the storage network. The use of fibre optic cables with SFP+ connectors enables a stable and high-performance connection. The PCI Express interface ensures fast data transfer between the server processor and the HBA. The Hot-Plug function allows the adapter to be inserted or removed during operation, simplifying maintenance and scaling of server environments.

Compatibility and Accessories

The adapter is compatible with a range of Lenovo ThinkSystem server models, including SR630, SR650, SR635, SR655, SR850, SR860, and SR950. Supported operating systems include 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. Certifications include, among others, EU CE marking, FCC Class A, RoHS, and TÜV, confirming compliance with international safety and emission standards.

Installation and Mounting

The adapter is installed internally within the server and requires a free PCI Express slot. The Hot-Plug function allows installation without server restart, maximizing uptime. Connection to the storage system is made via a fibre optic cable with SFP+ connector. Installation should be carried out according to the technical instructions provided by the server manufacturer.

Operational Advantages

Using the Lenovo 4XC7A76498 provides a high data transfer rate of 32 Gbit/s, ensuring fast access to storage resources. The Hot-Plug function reduces downtime during maintenance. Compatibility with various operating systems and server models increases flexibility in system design. Certifications guarantee compliance with safety and emission standards, which is essential for use in professional environments. The operating temperature range of 0 to 55 °C and relative humidity of 5 to 95 % allow for use in standardized server rooms.
