1System overview
The Dell™PowerEdge™C6145 is an ultra-dense 2U, shared infrastructure server that can support
up to two 4-socket servers featuring the AMD Opteron™ 6100, 6200 and 6300 series processors.
Each independent server features dual or quad AMD Opteron 6000 series 8-core 12-core, or
16-core processors, SR56x0 chipset with SP5100 for I/O connectivity, DDR3 memory, DIMM thermal
sensors, PCI Express Generation 2 (PCIe 2.0), dual-port embedded gigabit Ethernet controllers, and
the integrated Intelligent Platform Management Interface (IPMI) 2.0 baseboard management
controller (BMC) with a dedicated RJ45 connection.
The PowerEdge C6145 is primarily used in high performance computing (HPC) environments, but
has many applications for other uses including:
HPC (large compute, graphics processing unit (GPU) compute)
—Oil and gas
—Life sciences
—Computational/fluid dynamics
Online gaming
Engineering design assessment (EDA—large memory)
Film/entertainment
Dense, HPC cluster environment
Core, memory, and I/O constrained applications
I/O constrained GPU farm
—PCIe 2.0 x16 delivers the maximum in the industry
Large memory footprint
—32 DIMMs per server in 2U
Key technologies

The PowerEdge C6145 has 32 memory sockets split into 4 sets of 8 sockets with one set of memory
sockets per processor. Each 8-socket set is organized into 4 channels, with 2 memory sockets per
channel.
Supported memory
The DDR3 memory interface consists of 4 channels, with up to 2 RDIMMs per channel for dual rank
(DR). The PowerEdge C6145 supports 4GB, 8GB, 16GB and 32GB low-voltage RDIMMs at
1066/1333/1600MT/s DDR3 frequencies.
The PowerEdge C6145 supports the DIMMs listed in Table 6. For the latest information on supported
memory, visit Dell.com/PowerEdgeC.

Memory configurations
The PowerEdge C6145 server supports flexible memory configurations ranging from capacities of
4GB to 512GB (or 1TB per chassis). The PowerEdge C6145 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. RDIMM and UDIMM cannot be mixed.
For more information on memory configuration, see the Dell PowerEdge C6145 Systems Hardware
Owner’s Manual on Dell.com/Support/Manuals.

17 Dell PowerEdge C6145 Rack Server Technical Guide
Memory speed
The PowerEdge C6145 supports up to 1600MT/s memory performance with all channels and DIMMs
fully populated as long as the memory speed is 1600MT/s.
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 7 lists memory configuration and performance details for the PowerEdge C6145 based on the
population of the number and type of DIMMs per memory channel.

5Storage
Each server node can have up to a maximum of 12 hard drives, depending on the number of
independent server nodes and drive type (3.5-inch or 2.5-inch) that are installed in each PowerEdge
C6145 chassis. To accommodate the supported drive options, the PowerEdge C6145 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 midplanes with dedicated power and controller
connections for each of the two nodes. All drive slots can be hot-swapped, 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 C6145 system supports up to 12 hard disk drives per server node, depending on the
number of installed nodes (1-2) and drive type (2.5-inch or 3.5-inch). The number of drives that can
be installed depends on the processor TDP wattage. Hard drives must use the PowerEdge C6145
specific drive carrier.
The PowerEdge 6145 supports the following hard drive types:
7.2K, 10K and 15K RPM 2.5-inch and 3.5-inch SAS drives
7.2K RPM Enterprise 2.5-inch and 3.5-inch SATA
The following hard disk drive configurations are for a two-node solution:
—Up to 6 x 3.5-inch SATA (6 HD-85W, 4 HD–115W, 4HD-140W)
—Up to 6 x 3.5-inch SAS (6 HD-85W, 4 HD–115W, 4HD-140W)
—Up to 12 x 2.5-inch SATA (12 HD-85W, 9 HD-115W, no 140W processor support)
—Up to 12 x 2.5-inch SAS (12 HD-85W, 9 HD-115W, no 140W processor support)
—Up to 12 x 2.5-inch SSD
The following hard disk drive configurations are for a single-node solution:
—Up to 12 x 3.5-inch SATA (12 HD-85W, 8 HD–115W, 8HD-140W)
—Up to 12 x 3.5-inch SAS (12 HD-85W, 8 HD–115W, 8HD-140W)
—Up to 24 x 2.5-inch SATA (12 HD-85W, 9 HD-115W, no 140W processor support)
—Up to 24 x 2.5-inch SAS (12 HD-85W, 9 HD-115W, no 140W processor support)
—Up to 24 x 2.5-inch SSD

Optical drive
The PowerEdge C6145 chassis does not support optical drives. If needed, any external USB 2.0
compliant drive can be used, although no specific vendors have been qualified.
Tape drive
The PowerEdge C6145 chassis does not support an internal tape drive. External storage peripherals
are not directly validated with PowerEdge C6145, but customers can use any supported
network-based storage options validated with our network and fabric card matrix.
