Overview

This chapter provides an overview of the Cisco UCS C24 server features.

The figures in this chapter show an overview of external server features. Internal server features are illustrated in Figure 3-4.

The server is orderable in three different versions, each with one of three different front panel/backplane configurations:

  • Cisco UCS C24 (small form-factor (SFF) drives, with 24-drive backplane and expander).
    Holds up to twenty-four 2.5-inch hard drives or solid state drives.
  • Cisco UCS C24 (small form-factor (SFF) drives, with 16-drive backplane, no expander).
    Holds up to sixteen 2.5-inch hard drives or solid state drives.
  • Cisco UCS C24 (large form-factor (LFF) drives, with 12-drive backplane and expander).
    Holds up to twelve 3.5-inch hard drives.

Figure 1-1 shows the front panel features of the Small Form-Factor drives version of the server. This version of the server can be ordered with either a 16-drive direct-connect backplane or a 24-drive backplane with an expander. When the 16-drive backplane is installed, only the first 16 drive bays are used.

Table 1-1 Cisco UCS C24 Server Features

Chassis

Two rack-unit (2RU) chassis.

Processors

Two Intel Xeon E5-2400 Series processors.

Memory

The server provides 12 DIMM1 sockets on the motherboard.

Multi-bit error protection

This server supports multi-bit error protection.

Baseboard management

Pilot III BMC, running Cisco Integrated Management Controller (CIMC) firmware.

Depending on your CIMC settings, the CIMC can be accessed through the
10/100/1000 Ethernet dedicated management port, the 1-Gb Ethernet LOM ports, or a Cisco P81E virtual interface card.

Network and management I/O

The server provides these connectors:

  • One 1-Gb Ethernet dedicated management port
  • Two 1-Gb Base-T Ethernet LAN ports
  • One RS-232 serial port (DB-9 connector)
  • One 15-pin VGA2 connector
  • Six USB3 2.0 connectors

WoL

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

Power

Two power supplies: Both either 450 W each or 650 W each. Do not mix power supply types.

Redundant as 1+1. See Power Specifications.

ACPI

This server supports the advanced configuration and power interface (ACPI) 4.0 standard.

Cooling

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

PCIe I/O

Five horizontal PCIe4 expansion slots on two risers.

See PCIe Slots 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 that provide hot-pluggable access. There are two versions of the server front panel and backplane:

  • Cisco UCS C24 (small form-factor (SFF) drives, with 24-drive backplane and expander). Holds up to twenty-four 2.5-inch hard drives or solid state drives.
  • Cisco UCS C24 (small form-factor (SFF) drives, with 16-drive backplane, no expander). Holds up to sixteen 2.5-inch hard drives or solid state drives.
  • Cisco UCS C24 (large form-factor (LFF) drives, with 12-drive backplane and expander). Holds up to twelve 3.5-inch hard drives.

Internal USB support

The server has one internal USB 2.0 socket on the motherboard that you can use with a USB thumb drive for additional storage.

The server can be ordered with an optional blank 8-GB Cisco USB Flash Drive pre-installed in the internal USB port.

Disk Management
(RAID)

For a list of RAIDRAID Controller Considerations.

RAID Backup

There are two mounting points inside the chassis that can be used for the SuperCap power module that is used with LSI MegaRAID-CV card.

Video

Matrox G200e video controller. Resolution up to 1920 x1200, 16bpp at 60 Hz. 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
