redundant failsafe hypervisors, the R620 keeps your data center running with rock-steady reliability.
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.
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.
The Dell OpenManage™ systems management portfolio includes the Integrated Dell Remote Access
Controller (iDRAC) with Lifecycle Controller. Innovative embedded management features help 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 control and capitalize on your existing investment. OpenManage simplifies the
lifecycle of deploying, updating, monitoring, and maintaining your Dell PowerEdge servers.

The Dell™ PowerEdge™ R620 features the Intel®Xeon®processor E5-2600 product family, which
offers an ideal combination of performance, power efficiency, and cost. These processors provide
high performance no matter what your constraint is—floor space, power, or budget—and on
workloads that range from the most complicated scientific exploration to crucial web-serving and
infrastructure applications. 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.
The new Intel Xeon processor E5-2600 product family not only adds new features, but also
improves upon many features of the predecessor Intel Xeon processor 5600 series, including:
Up to two additional cores and up to 8MB more last level cache
More memory—six additional DIMMs and support for up to 32GB DIMMs, which increases
memory capacity from 288GB to 768GB
Intel Integrated I/O has support for up to 80 lanes of PCIe 3.0, which can reduce latency
Faster connections are provided throughout the system with support for DDR3 1600MT/s
memory and 8.0 GT/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
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 delivers up to double the boost than the
previous-generation turbo technology
Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

The R620 can connect to the PowerEdge C410x through an iPass cable. The NVIDIA requires one
x16 PCIe slot.
Some operating systems have not been validated to support GPUs. See Table 25 and Table 26 for
more information on operating system support of GPUs.
The Intel C600 chipset is implemented on the PowerEdge R620. For more information, visit
Intel.com.

More memory options are available than ever before with the Dell™ PowerEdge™ R620—greater
capacities, higher frequencies, and more flexibility. The R620 supports up to 768GB of memory
(24 DIMMs) and speeds up to 1600 MT/s, providing high performance in a variety of applications.
High memory density means there is no compromise when it comes to virtualization.
Increase your uptime and reduce data loss, due to Dell’s focus on reliability, availability, and
serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults which require
service, increasing your memory reliability. System uptime is reinforced with RAS features like
memory mirroring, sparing, and many others.
In addition to supporting existing unbuffered DIMMs (UDIMM) and registered DIMMs (RDIMM), the
R620 supports load reduced DIMMs (LRDIMM), which use a buffer to reduce memory loading and
provide greater density, allowing for the maximum platform memory capacity.

Flexible memory configurations are supported on the R620, ranging from capacities of 2 GB
(minimum) to 768 GB (maximum). 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.
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 Systems Owner’s
Manual on Support.Dell.com/Manuals.

The R620 supports memory speeds of 1600 MT/s, 1333 MT/s, 1066 MT/s, and 800 MT/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 10 lists memory configuration and performance details for the R620 based on the population
of the number and type of DIMMs per memory channel.
