1System overview
Introduction
The 1- socket Dell™ PowerEdge™ R320 rack server delivers powerful performance and
Enterprise-class high availability capabilities in a 1U chassis. The R320’s configuration flexibility,
increased internal storage, and straightforward systems management make it an excellent fit
for web hosting and serving, file and print serving, and other general purpose applications in
space-constrained locations.
Enterprise features, scalable expandability, and value in a dense chassis
The R320 features the scalable performance of the Intel®Xeon®processor E5- 2400 product family
with Enterprise-class memory RAS features. This server complements its processors with six DIMM
slots and two PCI Express®(PCIe) slots, providing a substantial memory footprint and wide I/O
bandwidth to support memory-intensive applications and databases as well as consolidation and
virtualization. For users not needing the Enterprise-class high performance of the Intel processor
Xeon E5-2400 product family, the R320 also supports the more price-sensitive Intel Xeon processor
E5-1410 and Intel Pentium®
processor 1400 product family.
Users selecting the Intel Xeon processor E5-2400 product family can choose to implement
advanced memory protection capabilities (memory sparing and memory mirroring) previously not
seen in the 1-socket x86 server space. These capabilities are not possible with the Intel Xeon
processor E5-1410 and the Intel Pentiumprocessor 1400 product family. Regardless of the
processor type, you can take advantage of other high availability features offered on the R320. To
protect your virtualized workloads, the R320 offers redundant SD cards making your hypervisors
redundant and failsafe. Other reliability and availability features include hardware and software RAID
options, hot plug hard drives and hot plug power supplies.
Ideal for your applications
The R320 features up to 100% more processor cores, enterprise-class RAS features including
memory sparing and memory mirroring, and 100% more internal hard drives than the
previous-generation R310. Network options span multiple third-party brands and adapter types
with 10GbE NIC, 10GbE FCoE, and Fiber Channel 8Gb HBA. The R320 delivers failsafe hypervisors
to protect virtualized workloads and is Fresh Air compliant, enabling it to operate in extended
temperature ranges. This not only helps to save energy costs but also allows the R320 to ride
through unforeseen events such as power brownouts. Its innovative, agent-free systems
management delivers no-compromise enterprise-class systems management for hassle-free
computing. These combined capabilities make the R320 an excellent fit for web hosting and serving,
file and print serving, and work group collaboration and productivity applications, especially where
the low-profile of a 1U chassis is desired.
The PowerEdge server line
The PowerEdge family is engineered with the right combination of features and performance
scalability to handle tough workloads for both large and small data center environments.
The Dell OpenManage™ systems management portfolio includes Integrated Dell Remote Access
Controller 7 (iDRAC7) with Lifecycle Controller. This embedded feature helps IT administrators
manage Dell servers in physical, virtual, local and remote environments, operating in-band or out-
of- band, with or without a systems management software agent. OpenManage integrates and
connects to third-party systems management solutions so you can maintain your single point of

15 PowerEdge R320 Technical Guide
4Processor
The Dell PowerEdge R320 features a variety of Intel processor options. The Intel Xeon processor
E5-2400 product family offers an ideal combination of performance, dependability, and cost. These
processors provide substantial performance and capacity for entry and mainstream workloads. In
addition to providing raw performance gains, improved I/O is also made possible with Intel
Integrated I/O, which can reduce latency by adding more lanes and doubling bandwidth. This helps
to reduce network and storage bottlenecks, unleashing the processor’s performance capabilities.
In addition to the Intel Xeon processor E5-2400 product family, the R320 also supports the Intel
Xeon E5-1410, which provide a balance of performance, value, and advanced features, and the Intel
Pentium processor 1400 product family, which is cost- efficient and provides the basic features.
Processor features
The new Intel processors provide the following features:
•Up to 8 execution cores per processor
•Intel Hyper-Threading technology enables up to 16 computational threads
•Micro-architecture on 32nm process for greater performance per watt
•Support for more memory—up to 6 DIMM slots and support for up to 32GB DIMMs increasing
the memory capacity from 32GB to 192GB
•Integrated memory controller with 3 channels of DDR3 and 46- bit physical addressing facilitate
greater memory capacity
•Up to 24 PCIe 3.0 links capable of 8.0 GT/s
•Faster connections throughout the system with support for up to DDR3 1600MT/s memory and
8.0GT/s QPI
•Intel Data Direct I/O (DDIO) allows I/O traffic to skip the main system memory and be directed
straight to the processor cache, which can provide a significant reduction in latency as well as
allowing memory to remain in a low-power state
•High bandwidth, low latency, bidirectional ring interconnect allows faster access to up to 20MB
multi-banked last level cache
•Intel Advanced Vector Extensions offer up to double the floating point operations per clock
cycle by doubling the length of registers, which can be useful for addressing very complex
problems or dealing with large-number calculations, which are integral to many technical,
financial, and scientific computing problems
•Intel Turbo Boost Technology 2.0, which allows processor cores to run faster than the base
operating frequency if it's operating below power, current, and temperature specification limits,
delivers up to double the boost than the previous generation
•Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

Memory configurations
Flexible memory configurations are supported on the R320, ranging from capacities of 2GB to
192GB. The system supports up to 6 DIMMs per processor. The R320 has 3 memory channels per
processor, with each channel supporting up to 2 DIMMs.
The R320 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 can be used in a system. UDIMMs and RDIMMs cannot be
mixed.
The following additional memory population guidelines apply to the R320:
•Up to two quad-rank (QR), dual-rank (DR), or single-rank (SR) DIMMs may be populated per
channel.
•DIMMs must be installed in each channel, starting with the DIMM farthest from the processor.
•DIMMs should be installed with largest rank count to smallest. For example, if DR DIMMS are
mixed with SR DIMMs, DR DIMMS should be placed in the lowest DIMM slots, followed by the SR
DIMMs.
For more information on memory configuration, see the
Dell PowerEdge R320 Systems Owner’s
Manual
on Support.Dell.com/Manuals.

Memory speed
The R320 supports memory speeds of 1600MT/s, 1333MT/s, 1066MT/s, and 800MT/s depending on
the DIMM types installed and the configuration. All memory on all processors and channels run at
the same speed and voltage. By default, the systems run at the highest speed for the channel with
the lowest DIMM voltage and speed. The operating speed of the memory is also determined by the
maximum speed supported by the processor, the speed settings in the BIOS, and the operating
voltage of the system.
Table 9 lists memory configuration and performance details for the R320 based on the population of
the number and type of DIMMs per memory channel.

Memory RAS features
Reliability, availability, serviceability (RAS) features help keep the system online and operational
without significant impact to performance, and can decrease data loss and crashing due to errors.
RAS aids in rapid, accurate diagnosis of faults that require service. Table 10 describes the RAS
features supported on the R320.
Table 10. Memory RAS features
Feature Description
Dense configuration
optimized profile
Increased memory reliability can be a result from this selectable platform profile
that adjusts parameters to reduce faults regarding refresh rates, speed,
temperature and voltage.
Memory demand and
patrol scrubbing
Demand scrubbing is the ability to write corrected data back to the memory once
a correctable error is detected on a read transaction.
Patrol scrubbing proactively searches the system memory, repairing correctable
errors.
Recovery from single
DRAM device failure
Recovery from Single DRAM Device Failure (SDDC) provides error checking and
correction that protects against any single memory chip failure as well as multi-bit
errors from any portion of a single memory chip.
Failed DIMM isolation This feature provides the ability to identify a specific failing DIMM channel pair,
thereby enabling the user to replace only the failed DIMM pair.
Memory mirroring:
intra-socket
Memory mirroring is a method of keeping a duplicate (secondary or mirrored)
copy of the contents of memory as a redundant backup for use if the primary
memory fails. The mirrored copy of the memory is stored in memory of the same
processor socket.
Memory address parity
protection
This feature provides the ability to detect transient errors on the address lines of
the DDR channel.
Memory sparing (rank) Memory sparing allocates one rank per channel as a spare. If excessive correctable
errors occur in a rank or channel, it is moved to the spare area while the operating
system is running to prevent the error from causing an uncorrectable failure.
Memory thermal
throttling
This feature helps to optimize power/performance and can also be used to
prevent DIMMs from overheating.
For information on memory mirroring and sparing configurations, see the
Dell PowerEdge R320
