Lenovo 4Y37A09735 Lenovo ThinkSystem RAID 940-16i RAID controller PCI Express x8

The ThinkSystem RAID 94 family of PCIe 4. 12 Gbps SAS RAID controllers are high-performance RAID-on-chip (ROC) adapters for connectivity to drives internal to the server. These adapters support RAID levels , 1, 1, 5, 5, 6 and 6, and include an extensive list of RAS and management features.

The RAID 94 Series adapters all have a PCIe 4. host interface which doubles the bandwidth between the server and the adapter, compared to the previous generation RAID 93 adapters. This improves overall performance of the storage subsystem by supporting up to 3 million IOPS (JBOD mode) and up to 3 million IOPS in RAID (random reads).

RAID on Chip-based controllers such as the RAID 94 adapters have a dedicated processor that offloads all RAID functions from the server's CPU. With hardware acceleration for RAID 5 and 6 operations plus up to 8 GB dedicated memory for caching, the 94-8i, 16i and 32i offer the ultimate performance for ThinkSystem servers.
