If you plan to use the RAID 530-8i adapter in the server, it must have firmware 50.3.0-1032 or later applied before it can be used in the server. If the adapter you plan to use has older firmware, it must first be upgraded by installing it in a supported server and upgrading the firmware there. For more information, see https://datacentersupport.lenovo.com/us/zh/solutions/ht509177.
The RAID 530-8i adapter cannot be mixed with the RAID 730-8i 1G adapter.
The RAID 540-8i adapter can be mixed with other x40 series RAID/HBA adapters.
The RAID 730-8i-1G adapter is not available for North America.
The RAID 730-8i 2G adapter cannot be mixed with the RAID 730-8i 1G adapter or RAID 930-8i adapter.
If the rear 3.5-inch drive cage is installed, the RAID 930-24i adapter can only be installed in slot 3. If the rear 2.5-inch drive cage is installed, the RAID 930-24i adapter can only be installed in slot 1 or 2.
The RAID 940 adapters can be mixed with the 440-8i or 440-16i HBA adapters.
The RAID 940/440 adapters cannot be mixed with the RAID 930/730/530/430 adapters.
Oversubscription may exist in some configurations with NVMe switch adapters. For details, see: Internal storage.
When there are more than 16 NVMe SSDs, switch adapters must be selected.
External RAID adapters are not supported in slots 3, 6 or 8.
If a RAID 730-8i 1 GB/2 GB adapter is installed, ThinkSystem 2.5"/ 3.5" PM1653 Read Intensive SAS 24 Gb SSDs and ThinkSystem 2.5" PM1655 Mixed Use SAS 24 Gb SSDs cannot be installed.
