Lenovo Flex System Fabric SI4093 System Interconnect Module

The Lenovo Flex System Fabric SI4093 System Interconnect Module is designed to be the central nervous system of a modern data-center fabric. Built to power dense blade environments, it delivers scalable, high-bandwidth connectivity between server blades and the external network while simplifying management and reducing latency. This interconnect module supports a flexible mix of copper and fiber technologies, enabling you to tailor your network to exact workloads and distance requirements. With up to 10 x 10GBase-T uplinks and 14 expansion slots for SFP and SFP+ modules, the SI4093 is engineered for future-proof growth, virtualization, and multi-tenant deployments. It’s a compact, hot-swappable solution that minimizes downtime and keeps your compute resources focused on business-critical tasks. Whether you’re consolidating workloads, deploying private clouds, or fueling virtualization-heavy infrastructures, this module helps you unlock seamless, high-speed communication across the entire Flex System fabric.

• High-performance uplinks and expansive expansion: The SI4093 provides 10 x 10GBase-T uplinks for fast copper connectivity, accompanied by optical fiber options through SFP/SFP+ transceivers. It also features up to 14 expansion slots, giving you flexibility to deploy a hybrid fabric that blends copper and fiber to meet latency, distance, and bandwidth requirements across diverse workloads. This combination supports critical traffic such as virtual machine migrations, storage I/O, and cluster interconnects, keeping performance consistent even as your data center scales.
• Flexible, future-ready fabric design: By enabling both 10GBase-T and 10GBase-X paths, the SI4093 accommodates a wide range of network architectures—from classic Ethernet to converged data fabrics. The modular approach lets you upgrade or reconfigure the interconnect fabric without overhauling the chassis, so you can adapt to changing business needs, new transceiver technologies, and evolving security requirements without interrupting production workloads.
• Optimized for virtualization and cloud-scale workloads: This interconnect module is engineered to support virtualization, multi-tenant environments, and containerized applications by delivering predictable throughput and low latency across blade servers. The SI4093 helps isolate traffic, enable efficient VLANs and virtual networks, and ensure that storage, compute, and management traffic travel over distinct but high-speed paths. The result is improved VM density, faster provisioning, and better application performance in cloud-ready infrastructures.
• Easy management with seamless integration: Built for Lenovo Flex System ecosystems, the SI4093 integrates with Lenovo’s management tools to simplify configuration, monitoring, and firmware updates. Its design reduces downtime during upgrades and makes it straightforward to implement security policies, quality-of-service (QoS), and traffic-engineering rules across the fabric. This cohesion minimizes administrative overhead and accelerates time-to-value for IT teams.
• Reliability, reliability, reliability: The system interconnect module is designed for data-center availability, offering robust signaling and redundant paths where applicable. The hardware is built to withstand continuous operation in mission-critical environments, with hot-swappability to facilitate maintenance, upgrades, and fault isolation without disrupting active workloads. For organizations pursuing high availability and predictable performance, the SI4093 is a dependable backbone for the Flex System fabric.

How to Install Lenovo Flex System Fabric SI4093 System Interconnect Module

• Power down the Lenovo Flex System chassis or place it in maintenance mode as required by your IT policy. Ensure you follow proper shutdown procedures to protect running workloads.
• Open the chassis and locate an available interconnect bay designed to accommodate the SI4093 form factor. Confirm compatibility with your Flex System enclosure to avoid improper insertion.
• Insert the SI4093 into the designated interconnect bay, ensuring it seats firmly and latches securely. Do not force the module; if it does not seat easily, reseat and verify clearance around adjacent components.
• Connect uplink cables according to your network design. Install 10GBase-T copper cables for RJ-45 uplinks or insert the appropriate SFP/SFP+ transceivers for optical fiber paths. Route cables neatly to prevent strain on ports and maintain airflow.
• Power on the chassis and access the Lenovo management interface to verify module recognition. Configure uplink teams, VLANs, and fabric settings as needed for your environment. Enable any QoS or security policies required for your workloads.
• Run functional tests to confirm connectivity across all uplinks, verify latency and throughput, and validate that inter-switch connectivity, virtual networks, and storage paths are operating as intended.
