5Dell PowerEdge C6105 Rack Server Technical Guide
1System overview
The Dell™PowerEdge™C6105 is an ultra-dense 2U server that can support up to four independent
2-socket (2S) servers. Each independent server features single or dual AMD Opteron™4100 series,
4200 series and 4300 series 4-core, 6-core or 8-core processors, SR5670 chipset with SP5100 for
I/O connectivity, DDR3 memory, DIMM thermal sensors, PCI Express®(PCIe) 2.0, dual-port
embedded Gigabit Ethernet (GbE) controllers, and the integrated Intelligent Platform Management
Interface (IPMI) 2.0 baseboard management controller (BMC) with a dedicated RJ45 connection.
New technologies
The AMD Opteron 4100, 4200 and 4300 series microprocessors, part of the AMD Opteron 4000
series platform, are designed specifically for power-efficient and cost-optimized server applications.
These processors feature 4-core, 6-core, or 8-core processing to maximize performance-per-watt
at the best cost for data center infrastructures and highly dense deployments. The 2S server also
features an energy-efficient (EE) power band that delivers eight cores of performance at only 32W
TDP, as well as two 16-bit lanes of AMD HyperTransport™ 3.0 Technology links for peak bandwidth
of 25GB/second per link between processors and I/O.
With AMD Opteron 4000 processors, the PowerEdge C6105 server offers performance at a lower
power, scalability without compromise, and a platform upgrade path with the planned next-
generation processor. For more information, see the Processor section.

3Processor
AMD Opteron 4100, 4200 and 4300 series processors, part of the AMD Opteron 4000 series
platform, offer the world’s lowest power-per-core server processor, setting the foundation for cloud
workloads and affordability for mainstream infrastructure servers. AMD power-efficient server
processor designs are the first to break the six watt per core barrier. Compared to previous
generations, these designs allow customers to double the number of servers within the same power
budget.
Processor features
Features of the AMD Opteron 4200/4300 series include:
32nm process technology
Eight “Piledriver” processor cores (256b FPU)
New ISA extensions
Up to 16MB combined L2 + L3 cache
Two DDR3 memory channels supporting RDIMM and UDIMM
Two HyperTransport technology 3.0 links up to 6.4GT/s
Advanced Platform Management Link (APML) for system management
Increased frequency
Four to eight cores per processor
Same thermal support as previous generations
Supports 12 DIMMs in 2-socket servers such as the PowerEdge C6105
New “Piledriver” per clock instructions
Increased performance and power efficiency versus previous 4200 series processors
Compatible with C32 socket; requires a BIOS update

Processor configurations
The PowerEdge C6105 supports single- or dual-processor configurations. All processors must
match in all configurations.
The PowerEdge C6105 uses only 3.5-inch hard drives with limited configurations and 140W
AMD Opteron processors.
Processor installation
For information on processor installation, see the Dell PowerEdge C6105 Systems Hardware
Owner’s Manual on Dell.com/Support/Manuals.
Chipset
The PowerEdge C6105 uses the AMD SR5670 chipset. For more information, visit AMD.com.

4Memory
The PowerEdge C6105 uses DDR3 memory to provide a high-performance, high-speed memory
interface capable of low-latency response and high throughput. The PowerEdge C6105 supports
registered ECC DDR3 DIMMs (RDIMM) and unbuffered DIMMs (UDIMM); standard-voltage and low-
voltage DIMMs available. The PowerEdge C6105 does not support ultra-low-voltage (1.25V) memory
or 1600MT/s memory.
The PowerEdge C6105 contains 12 memory sockets split into two sets of six sockets, one set per
each processor. Each six-socket set is organized into two channels of three memory sockets per
channel.
Supported memory
The DDR3 memory interface consists of two channels, with up to three DIMMs per channel for dual
rank. The interface uses 4GB, 8GB and 16GB RDIMMs, or 2GB and 4GB UDIMMs. The memory mode
depends on how the memory is populated in the system.
Note: AMD Opteron processors 4130 and 4122 do not support low-voltage DDR3 or C1E.
The PowerEdge C6105 supports the DIMMs listed in Table 7. For the latest information on supported
memory, visit Dell.com/PowerEdgeC.

Memory configurations
The PowerEdge C6105 server supports flexible memory configurations ranging from capacities of
2GB to 192GB and up to 12 DIMM slots. The C6105 has two memory channels per processor, with
each channel supporting up to three DIMMs.
The PowerEdge C6105 supports a flexible memory configuration according to these basic rules:
Speed: If DIMMs of different speeds are mixed, all channels across all processors operate at the
slowest DIMM’s common frequency.
DIMM type: Only one type of DIMM is allowed per system. UDIMM and RDIMM cannot be mixed.
For more information on memory configuration, see the Dell PowerEdge C6105 Systems Hardware
Owner’s Manual on Dell.com/Support/Manuals.

19 Dell PowerEdge C6105 Rack Server Technical Guide
Memory speed
The PowerEdge C6105 supports up to 1333MT/s memory performance. The memory frequency is
determined by a variety of inputs, including the speed of the DIMMs. The configuration of the
DIMMs affects the speed of the processor.
Table 8 lists the memory population guidelines for the PowerEdge C6105 based on the population
of the number and type of DIMMs per memory channel.
Note: Although the PowerEdge C6105 supports DIMM speeds of 800MT/s and 1066MT/s, you can
purchase this system only with DIMM speeds of 1333MT/s on Dell.com/PowerEdgeC.

5Storage
Each server node can have up to a maximum of six hard drives, depending on the number of
independent server nodes and drive type (3.5-inch or 2.5-inch) installed in each PowerEdge C6105
chassis. To accommodate the supported drive options, the PowerEdge C6105 has one backplane
type for 12 x 3.5-inch drives and one for 24 x 2.5-inch drives. These drive slots are divided equally
across two independent mid-planes with dedicated power and controller connections for each of
the four nodes. All drive slots are hot-swap capable, and each Serial Attached SCSI (SAS) or Serial
ATA (SATA) slot has an LED indicator to indicate drive status and health.
Note: Mixing SAS and SATA drives is not supported.
Internal storage
The PowerEdge C6105 system supports up to 12 hard disk drives per server node depending on the
number of installed nodes (2-4) and drive type (2.5-inch or 3.5-inch). The PowerEdge 6105 supports
the following hard drive types and configurations:
7.2K, 10K and 15K RPM 2.5-inch and 3.5-inch SAS drives
Support for 5.4K and 7.2K RPM Enterprise 2.5-inch and 3.5-inch SATA
Note: Hard drives must use the PowerEdge C6105 specific drive carrier; this drive carrier is not
shared with any other PowerEdge platforms, or other PowerEdge C platforms such as the C1100
and C2100.
The following per-node, hard disk drive configurations for a four-node solution:
—Up to 3 x 3.5-inch SATA
—Up to 3 x 3.5-inch SAS
—Up to 6 x 2.5-inch SATA
—Up to 6 x 2.5-inch SAS
—Up to 6 x 2.5-inch SSD
