20    PowerEdge C6220 II Technical Guide     
5 Storage 
The direct backplanes can be used in configurations of up to four nodes. The expander can support 
one to four nodes, but it cannot be ordered or shipped from the factory in less-than-full-chassis 
configurations. By default the hard drive slots are divided equally across server nodes, but the 
2.5-inch chassis with expander allows the user to define how the drives are split. All drive slots are 
hot-swap capable, and each SAS or SATA slot has two LED indicators to indicate drive status and 
health. 
In addition, the PowerEdge C6220 II has a MicroSD slot located on the PCIe riser for loading an 
embedded hypervisor. This riser is optional in the 1U nodes and default in the 2U nodes. 
PowerEdge C6220 II MicroSD card reader 
The PCIe risers on the PowerEdge C6220 II include a MicroSD card reader slot. Cards installed in this 
slot can be used for storing an embedded hypervisor. 
PowerEdge C6220 II hard drive cable routing  
The SAS/SATA signals in the PowerEdge C6220 II are routed via a thin, flexible cable. Hard drive 
controller connectors are provided near the expansion slots to facilitate easier connection between 
the controller and system board. The advantages of this design are: 
  The best possible signal integrity 
  Support for six 3.5-inch drives per 2U node 
Half of the HDD signals for 2U sled configurations are routed through the upper midplane to provide 
additional bandwidth. 
Internal storage 
The PowerEdge C6220 II supports up to 24 hard drives per server node depending on the number 
of installed nodes and the backplane type (2.5-inch direct, 2.5-inch expander or 3.5-inch expander). 
  Support for 7.2K, 10K and 15K RPM 2.5-inch and 3.5-inch SAS drives 
  Support for 7.2K RPM Enterprise 2.5-inch and 3.5-inch SATA drives 
  Use of the PowerEdge C6220 II-specific drive carrier 
Note: The C6220 II shares this drive carrier with any other PowerEdge C platform, such as 
C6100, C6105, C6145 and C6220.
