The RAID 940 Series adapters all have a PCIe 4.0 host interface which doubles the bandwidth between the server & 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) & up to 3 million IOPS in RAID (random reads).\n\n 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 & 6 operations plus up to 8 GB dedicated memory for caching, the 940-8i, 16i & 32i offer the ultimate performance for Think System servers.\n\n\n\n\n\n\n\n Model: 4Y37A09728\n\n\n\n\n\n\n\n
