Product Description
The Lenovo 01PE818 ThinkSystem 940-16i is a powerful 16-port internal SAS/SATA RAID controller designed to provide high-performance storage connectivity for Lenovo ThinkSystem servers. This controller leverages the latest PCI Express Gen4 interface, offering significantly increased bandwidth compared to previous generations, which is crucial for demanding applications and high-speed storage devices like NVMe SSDs (when used with appropriate adapters or configurations). With 16 internal ports, the 940-16i provides extensive connectivity options for internal drives. It supports a wide range of RAID levels, including 0, 1, 5, 6, 10, 50, and 60, allowing administrators to configure storage arrays based on their specific needs for performance, redundancy, or a balance of both. The inclusion of an 8GB Flash-backed write cache (FBWC) significantly accelerates write operations by temporarily storing data before it is written to the drives, improving overall system responsiveness and performance. This RAID controller is designed for enterprise environments where data integrity and performance are paramount. It supports hot-plug functionality, allowing drives to be added or removed without shutting down the server, which is essential for maintaining high availability. The 01PE818 is an ideal choice for building high-performance storage solutions, supporting a large number of drives (potentially up to 24 with the use of SAS expanders), and ensuring reliable data protection for critical business data.
