Lenovo ThinkSystem SR635 2.5" NVMe Gen4 2-Bay Rear Drive Kit v2

The Lenovo ThinkSystem SR635 2.5" NVMe Gen4 2-Bay Rear Drive Kit v2 is a purpose-built expansion solution designed to maximize performance and efficiency in a compact server footprint. This rear-drive kit enables two hot-swappable 2.5-inch NVMe drives to be mounted at the back of the ThinkSystem SR635 family, freeing front bays for maximum I/O flexibility and improved airflow. Built for data-intensive workloads, this kit helps accelerate databases, virtualization, big data analytics, and high-velocity caching apps by delivering the speed of NVMe Gen4 with the reliability and manageability Lenovo is known for. Whether you’re expanding storage for a growing virtualization environment, implementing a high-performance database, or adding fast scratch space for in-memory workloads, this rear drive kit is designed to integrate seamlessly with your SR635 server and existing backplane, ensuring a clean, organized configuration with minimal downtime.

• Dual 2.5-inch NVMe Gen4 drive bays in a compact rear-facing kit provide high-bandwidth storage expansion for demanding workloads. By leveraging NVMe Gen4, you benefit from lower latency and higher throughput compared to traditional SAS/SATA options, making this kit ideal for databases, VDI, and large-scale caching applications.
• Rear-mounted design for optimized airflow and cabling This kit moves storage to the back of the chassis, freeing front-panel space and promoting improved cooling efficiency. The result is a cleaner interior with reduced cable clutter, which can help sustain performance under heavier I/O loads.
• Tool-free drive carriers and streamlined installation The enclosure ships with user-friendly, tool-free carriers that simplify drive installation and replacement. This translates to faster maintenance windows, reduced downtime, and easier upgrades for administrators managing growing storage needs.
• Plug-and-play compatibility with Lenovo ThinkSystem SR635 Designed to integrate with the SR635 family, this rear drive kit aligns with Lenovo’s backplane ecosystem to ensure reliable operation and consistent firmware behavior. It’s an excellent option for organizations standardizing on ThinkSystem hardware and seeking a scalable storage upgrade without complex reconfiguration.
• Reliable, enterprise-grade build with Lenovo support Expect durable construction and Lenovo’s support ecosystem, including warranty coverage and access to Lenovo’s service network. This kit is built to endure the rigors of data-center environments and to support ongoing maintenance with minimal disruption to operations.
