Server model: eight 2.5-inch SAS/SATA drives, eight 2.5-inch NVMe drives, the rear hot-swap drive
assembly, three 8i RAID adapters, one NVMe switch adapter
Notes:
• The cable routing illustration is based on the scenario that the rear hot-swap drive assembly is installed.
Depending on the model, the rear hot-swap drive assembly and the 8i RAID adapter on PCIe slot 6 might
not be available on your server.
• Depending on the model, if the NVMe switch adapter is installed on PCIe slot 1, route the NVMe signal
cable along the right side of the chassis.
