This chapter provides an overview of the Cisco UCS C220 M4 server features:
The figures in this section show an overview of external server features.
The server is orderable in two different versions, each with one of two different front panel/backplane configurations:
Figure 1-1 shows the front panel features of the SFF drives, eight-drive version of the server.

---|---|
24 DDR4 DIMM1 sockets on the motherboard (12 each CPU). |
|
BMC, running Cisco Integrated Management Controller (Cisco IMC) firmware. Depending on your Cisco IMC settings, Cisco IMC can be accessed through the |
|
|
|
Dedicated socket that can be used to add an mLOM card for additional rear-panel connectivity (up to four 1-Gb or 10-Gb Ethernet ports). |
|
1-Gb BASE-T Ethernet LAN ports support the wake-on-LAN (WoL) standard. |
|
Do not mix power supply types or wattages in the server. Redundant as 1+1. See Power Specifications. |
|
The advanced configuration and power interface (ACPI) 4.0 standard is supported. |
|
Two horizontal PCIe4 expansion slots on two risers (single riser assembly). See Replacing a PCIe Card for specifications of the slots. |
|
The bus slots in this server support the InfiniBand architecture. |
|
Drives are installed into front-panel drive bays. The server is orderable in two different versions, each with different front panel/backplane configurations
This version of the server also supports up to two NVMe PCIe SSDs in bays 1 and 2. NVME PCIe SSDs are hot-pluggable.6 NVMe drives require PCIe riser version 2B in the server to provide the PCIe bus connection. |
|
One internal USB 3.0 port on the motherboard that you can use with a USB thumb drive for additional storage. |
|
Two internal bays on the motherboard for up to two SD cards. The two flash drives can be configured in a RAID 1 configuration. |
|
The server has a dedicated internal riser for a PCIe-style Cisco modular RAID controller card. The server can optionally use its own embedded SATA RAID controller. You can optionally add a RAID 5 key to upgrade this embedded SATA RAID. Note The embedded RAID option is not available with the large form factor drives, four-drive version of the server at this time. For a list of supported RAID controller options, see RAID Controller Considerations. |
|
The server has a mounting bracket for the supercap power module that is used with Cisco modular RAID controller card. |
|
VGA video resolution up to 1920 x 1200, 16 bpp at 60 Hz, and up to 256 MB of video memory. |
5.Hot swappable = no shutdown of the components is required before removal with the server power on. 6.Hot-pluggable = shutdown of the components is required before removal with the server power on. |
