1System overview
Introduction
Designed for extraordinary performance on a wide range of applications, the Dell™PowerEdge™
R620 rack server is an impressive general-purpose platform that is perfect for data centers with
space constraints. With its hyper-dense memory —up to 768GB in a 1U form factor —and powered
by the Intel®Xeon®processor E5-2600 and E5-2600 v2 product families, the R620 shines when
handling virtualization, high-performance computing (HPC), and workgroup collaboration
applications.
Accomplish more
Pack more computing power into a space-challenged data center with the PowerEdge R620, which
offers an exceptionally large memory footprint along with balanced, scalable I/O capabilities,
including integrated PCI Express®(PCIe) 3.0 capable expansion slots. With reliability, availability and
serviceability (RAS) features like hot-pluggable fans, drives, power supply units (PSUs) and even
redundant failsafe hypervisors, the R620 keeps your data center running with rock-steady reliability.
Dense design for demanding workloads
Virtualization environments demand high memory capacity to maximize the number of virtual
machines per server, and the PowerEdge R620 was designed specifically with these environments in
mind. The R620 also offers outstanding computational density for HPC application clusters by
providing powerful processing capabilities in a compact form factor.
Tailor your network fabric
The R620’s network features allow you to tailor your network throughput to match your application
needs, enabling added I/O performance. Dell Select Network Adapters, our flexible NIC technology,
let you choose the right network fabric without using up a valuable PCI slot. You can pick speed,
technology, vendor, plus other options such as switch independent NIC partitioning, which lets you
share and manage bandwidth on 10GbE connections.
Simplified systems management, without compromise
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 installed.
OpenManage iDRAC with Lifecycle Controller integrates and connects to leading third-party
systems management solutions (such as those from Microsoft, VMware and BMC Software), so users
can maintain a single point of control and capitalize on an existing systems management investment.
OpenManage simplifies the lifecycle of deploying, updating, monitoring and maintaining Dell
PowerEdge servers.

E5-2600 v2 processors can help you achieve more computational horsepower, in the same
footprint, with better security and power efficiency.
Processor features
The Intel Xeon processor E5-2600 v2 product family has powerful new features and improves upon
many of the capabilities of the predecessor Intel Xeon processor E5-2600 series:
With up to four additional cores, 10MB more cache and a 17% increase in memory speeds,
E5-2600 v2 processors may boost performance by up to 40% in Dell PowerEdge server
platforms.
Support for DDR3 1866MT/s memory provides faster connections throughout the system.
Up to 24 DIMM slots and support for up to 32GB DIMMs enable memory capacity of 768GB.
Dell’s exclusive Fault Resilient Memory technology provides a protected memory zone for a
hypervisor without consuming half of the total RAM in the system.
In combination with Fault Resilient Memory, E5-2600 v2 processors offer Failsafe Virtualization
for unsurpassed industry protection for virtual machines.
Intel Secure Key and Intel OS Guard deliver faster and more secure encryption.
Advanced Programmable Interrupt Controller virtualization (APICv) improves virtualization
performance by reducing virtual machine (VM) exits, thereby reducing overhead required to
service every APIC interrupt.
Intel Integrated PCI Express 3.0 provides up to 40 lanes per socket.
Intel Turbo Boost Technology 2.0 delivers up to double the boost of the previous generation
turbo technology.
Dell Processor Acceleration Technology (DPAT), enabled through the BIOS, minimizes transition
duration when the processor functions in turbo mode, thereby decreasing jitter and allowing for
lesser latency.
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.
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 in the large-number calculations
that are integral to many technical, financial and scientific computing problems.

Memory configurations
The R620 server supports flexible memory configurations ranging from capacities of 4GB to 768GB.
The system supports up to 12 DIMMs per processor (up to 24 DIMMs in a dual-processor
configuration). The R620 has four memory channels per processor, with each channel supporting
up to three DIMMs.
The R620 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, RDIMM or LRDIMM. These
types cannot be mixed.
The following additional memory population guidelines apply to the R620:
Up to two quad-rank (QR) DIMMs and up to three dual-rank (DR) or single-rank (SR) DIMMs may
be populated per channel. Although an LRDIMM is physically a QR DIMM, logic on the LRDIMM
can make it appear as a DR DIMM to the system, allowing up to three LDRIMMs 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 R620 Owner’s Manual on
Dell.com/Support/Manuals.
Memory speed
The R620 supports memory speeds of up to 1866MT/s, depending on the DIMM types installed and
the configuration. The loading within a channel significantly affects memory speed.
