Server models with four 3.5-inch hot-swap drives and eight 2.5-inch hot-swap drives 
(hardware RAID)
Use this section to understand the cable routing for server models with four 3.5-inch hot-swap drives and 
eight 2.5-inch hot-swap drives (hardware RAID).
Server model: four 3.5-inch hot-swap drives and eight 2.5-inch hot-swap drives (hardware RAID)
Notes: 
•  There are two types of configurations: 
–  Two 8i RAID adapters
–  One 16i RAID adapter
•  Ensure that all cables are routed through the correct cable clips.
