This chapter provides an overview of the Cisco UCS C220 M4 server features:

External Features Overview

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:

  • Cisco UCS C220 M4—Small form-factor (SFF) drives, with eight-drive backplane.
    This version holds up to eight 2.5-inch SAS hard drives or solid state drives (SSDs). This version supports up to two NVMe PCIe SSDs. See Figure 1-1.
  • Cisco UCS C220 M4—Large form factor (LFF) drives, with four-drive backplane.
    This version holds up to four 3.5-inch SAS hard drives. See Figure 1-2.
  • The rear panel features are the same for both versions of the server. See Figure 1-3.

Figure 1-1 shows the front panel features of the SFF drives, eight-drive version of the server.

Summary of Server Features

Table 1-1 lists the features of the server.

.

Table 1-1 Cisco UCS C220 M4 Server Features

Feature
Description

Chassis

One rack-unit (1RU) chassis.

Processors

Up to two Intel Xeon E5-2600 v3 Series processors.

Memory

24 DDR4 DIMM1 sockets on the motherboard (12 each CPU).

Multi-bit error protection

Multi-bit error protection is supported.

Baseboard management

BMC, running Cisco Integrated Management Controller (Cisco IMC) firmware.

Depending on your Cisco IMC settings, Cisco IMC can be accessed through the
1-Gb dedicated management port, the 1-Gb Ethernet LOM ports, or a Cisco virtual interface card.

Network and management I/O

Supported connectors:

  • One 1-Gb Ethernet dedicated management port
  • Two 1-Gb BASE-T Ethernet LAN ports
  • One RS-232 serial port (RJ-45 connector)
  • One 15-pin VGA2 connector
  • Two USB3 3.0 connectors
  • One front-panel KVM connector that is used with the KVM cable, which provides two USB 2.0, one VGA, and one serial (DB-9) connector.

Modular LOM

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).

WoL

1-Gb BASE-T Ethernet LAN ports support the wake-on-LAN (WoL) standard.

Power

Two power supplies:

  • AC power supplies 770 W AC each.
  • DC power supplies 1050 W DC each.

Do not mix power supply types or wattages in the server.

Redundant as 1+1. See Power Specifications.

ACPI

The advanced configuration and power interface (ACPI) 4.0 standard is supported.

Cooling

Six hot-swappable fan modules for front-to-rear cooling.

PCIe I/O

Two horizontal PCIe4 expansion slots on two risers (single riser assembly).

See Replacing a PCIe Card for specifications of the slots.

InfiniBand

The bus slots in this server support the InfiniBand architecture.

Storage

Drives are installed into front-panel drive bays. The server is orderable in two different versions, each with different front panel/backplane configurations

  • Cisco UCS C220 M4—Small form-factor (SFF) drives, with eight-drive backplane. Holds up to eight 2.5-inch SAS/SATA drives. SAS/SATA drives are hot-swappable.5

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.

  • Cisco UCS C220 M4—Large form factor (LFF) drives, with four-drive backplane. Holds up to four 3.5-inch SAS/SATA drives.

Internal USB

One internal USB 3.0 port on the motherboard that you can use with a USB thumb drive for additional storage.

SD cards

Two internal bays on the motherboard for up to two SD cards.

The two flash drives can be configured in a RAID 1 configuration.

Disk Management
(RAID)

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.gif

Noteblank.gif 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.

RAID Backup

The server has a mounting bracket for the supercap power module that is used with Cisco modular RAID controller card.

Video

VGA video resolution up to 1920 x 1200, 16 bpp at 60 Hz, and up to 256 MB of video memory.

1.DIMM = dual inline memory module

2.VGA = video graphics array

3.USB = universal serial bus

4.PCIe = peripheral component interconnect express

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.
