Technical rules for PCIe slots
PCIe adapters must be installed in a specific order based on the CPU configuration that you implement on your server.

ThinkSystem RAID 940-32i 8GB Flash PCIe Gen4 12Gb Adapter can only be installed in slot 9 in one CPU configurations, and installed in slot 9, 5, 6, 7, or 8 in two CPU configurations.
ThinkSystem RAID 540-8i PCIe Gen4 12Gb Adapter cannot be mixed with other RAID/HBA.
GPU RTX A6000 can only be installed in PCIe slot 1, 3, 5, and 7. PCIe slot 2, 4, 6, and 8 will be left unoccupied.
Mixing GPUs in the same zone are not supported:
When a GPU is installed in PCIe slot 1, 2, 3, or 4; only the same GPU can be installed in PCIe slot 1, 2, 3, or 4.
When a GPU is installed in PCIe slot 5, 6, 7, or 8; only the same GPU can be installed in PCIe slot 5, 6, 7, or 8.
When a RTX A6000/RTX 4000 GPU is installed in PCIe slot 1, 2, 3, or 4; RAID/HBA adapters cannot be installed in PCIe slot 1, 2, 3, or 4.
When a RTX A6000/RTX 4000 GPU is installed in PCIe slot 5, 6, 7, or 8; RAID/HBA adapters cannot be installed in PCIe slot 5, 6, 7, or 8.
