To locate the storage drives or drive bays, see “Front view” on page 15.
• Optical drive
Some server models have two optical drive bays. For more information, see “Front view” on page 15.
• Tape drive
A tape drive enables you to store data on tape media. For server models with two optical drive bays, you
can install an internal tape drive in the optical-drive bay 2.
• M.2 drive
Your server supports one M.2 backplane which provides an easy way for data storage. You can install up
to two M.2 drives into the M.2 backplane. For more information, see “Install the M.2 backplane and M.2
drive” on page 84.
Expansion slots
The server has six expansion slots on the system board for installing appropriate Peripheral Component
Interconnect Express (PCIe) adapters.
• For processor 1
– PCIe slot 1: PCIe x8 (x8, x4, x1), full-height, half-length
– PCIe slot 2: PCIe x16 (x16, x8, x4, x1), full-height, half-length
– PCIe slot 3: PCIe x16 (x16, x8, x4, x1), full-height, full-length, double-width
– PCIe slot 6: PCIe x8 (x4, x1), full-height, full-length
• For processor 2
