Cisco UCS C420 Server Features
Chassis
Two rack-unit (2RU) chassis.
Processors
Two or four Intel Xeon E5-4600 Series processors.
Memory
The server has 48 DIMM sockets on the motherboard. Each of the four CPUs can
support 12 DIMMs.
Multi-bit error
protection
This server supports multi-bit error protection.
Storage
Drives are installed into configurable (one or two) drive bay modules that provide
hot-pluggable front-panel access.
Each drive bay module can hold up to eight 2.5-inch SAS1 or SATA2 hard drives or
solid state drives, for a total of 16 drives.
The server also includes an internal USB 2.0 port on the motherboard.
The server also includes two internal bays for SD cards.
Disk
Management
For a list of supported RAID controller options, see RAID Controller
Considerations, page C-1.
There are also two mounting points inside the chassis for the optional LSI RAID
battery backup units that can be used with the controller cards.
RAID Backup
There are two mounting points inside the chassis (on the removable air baffle) that
can be used for Supercap power module backup units.
PCIe I/O
Seven PCIe3 expansion slots:
•
Two full-height, half-length, x16 horizontal slots on riser cards
•
Five half-height, half-length, x8 slots on motherboard
See Replacing a PCIe Card, page 3-41 for slot specifications.
InfiniBand
The bus slots in this server support the InfiniBand architecture.
Network and
management I/O
The server provides these rear panel connectors:
•
•
•
•
•
One 10/100/1000 dedicated management Ethernet port
Four 1-Gb Base-T Ethernet ports
One RS-232 serial connector
One 15-pin VGA4 connector
Three USB5 2.0 connectors
The server also has one front-panel KVM connector that is used with the included
KVM cable, which provides two USBs, one VGA, and one serial connector.
WoL
The 1-Gb Base-T Ethernet LAN ports support the wake-on-LAN (WoL) standard.
Power
Two power supplies, 1200 W each.
Redundant as 1+1.
ACPI
This server supports the advanced configuration and power interface (ACPI) 4.0
standard.
Cooling
Six fan modules, hot-swappable, redundant.
In addition, there is 1 fan in each power supply.
