Description
The RAID 940 Series adapters all have a PCIe 4.0 host interface which doubles the bandwidth between the server and the adapter, compared to the previous generation RAID 930 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 940 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 940-8i, 16i and 32i offer the ultimate performance for ThinkSystem servers.
