5 Storage
Each PowerEdge C5220 8-sled and 12-sled microserver can support a maximum of four 2.5-inch
SATA/SSD/SAS or two 3.5-inch SATA/SAS drives. The drives are not hot-pluggable as they are
embedded on each sled. Depending on which form factor of drive is used, the following hard drive
boards are installed in the individual sleds:
2.5-inch hard drives boards plug directly into the sled with the SATA onboard connectors. Each
2.5-inch drive is supported by a metal bracket that sits between the hard drive and the sled.
3.5-inch hard drives using a hard drive board require the cables to connect to the PowerEdge
C5220 system board SATA connectors.
In addition, the PowerEdge C5220 has a MicroSD slot located on the PCIe riser for loading an
embedded hypervisor.
PowerEdge C5220 MicroSD card reader
The PCI Express risers on the PowerEdge C5220 include a MicroSD card reader slot. Cards installed
in this slot can be used for storing an embedded hypervisor.
PowerEdge C5220 hard drive cable routing
When using the 3.5-inch hard-drive board, the hard drives require hard drive cables to connect
to the PowerEdge C5220 MB SATA connectors.
The connector on the system board side provides an electrical connection for hard drive board.
The PowerEdge C5220 uses the PCIe x8 and PCI x4 connectors on the system board side to
route both I/O signals (STA, LAN, and sideband signal) and power rails from the hard drives.
Internal storage
The PowerEdge C5220 supports up to four hard drives per server node depending on the number of
installed nodes (2-4) 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
