Lenovo RAID 940-8i 8GB Flash PCIe 4.0 x8 | SAS RAID Controller

Sustain demanding server workloads with the Lenovo ThinkSystem RAID 940-8i 8GB Flash PCIe Gen4 12Gb Adapter. This controller is built for internal drive connectivity in enterprise servers where throughput, data integrity, and recovery behavior matter. With PCIe 4.0 x8 host connectivity and 12 Gb/s SAS support, it is designed to keep storage paths responsive under sustained I/O. The 8 GB flash-backed cache helps preserve write performance while adding a layer of protection for cached data during unexpected power events. Support for RAID 0, 1, 5, 6, 10, 50, 60, and JBOD gives infrastructure teams flexibility to match protection levels to workload requirements, from capacity-focused arrays to fault-tolerant deployments. With 8 internal SAS ports, this adapter is suited to server platforms that need direct attachment to multiple drives without adding external complexity. It is a practical choice for teams standardizing on Lenovo ThinkSystem hardware and looking for a controller that balances performance, resilience, and serviceability in a single plug-in card.
