Server model: eight 2.5-inch SAS/SATA drives, eight 2.5-inch NVMe drives, one 16i RAID adapter, one
NVMe switch adapter
Note: The cable routing illustration is based on the scenario that the NVMe switch adapter is installed on
PCIe slot 1. If the NVMe switch adapter is installed on PCIe slot 5 or PCIe slot 6, route the NVMe signal cable
for front backplane 2 along the left side of the chassis.
