1System overview
Introduction
Designed for your taxing workloads, such as email, database and virtual environments, the Dell™
PowerEdge™M620 blade server is an ideal blend of density, performance, efficiency and scalability.
The M620 delivers unprecedented memory density and superb performance with no compromise
on enterprise-class features.
Accomplish more
Bring impressive new capabilities to your data center with the PowerEdge M620, which offers a
memory capacity of up to 768GB of RAM along with scalable I/O capabilities. Powered by Intel®
Xeon®E5-2600 or E5-2600v2 processors and Dell’s unique Select Network Adapter, our flexible NIC
technology, the M620 provides the performance you require and allows you to allocate your
network throughput to match your application needs.
Designed for your hyper-dense environments
Dell’s exclusive failsafe virtualization technology provides redundant media for hypervisor failover to
keep your critical virtual environments running. Your virtualization environments demand high
memory capacity in order to maximize the number of virtual machines per server, and the
PowerEdge M620 was designed with this in mind. If you are running high-performance computing
(HPC) application clusters, the M620 provides you with outstanding computational density and
powerful processing capability in a compact form factor.
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.
The PowerEdge M-series blade server line
Implement the right combination of features and performance scalability with the PowerEdge
M-series blade servers, which can handle tough workloads in a data center of any size. In addition to
the world-class management features provided in all PowerEdge servers, the M620 also takes
advantage of the capabilities of the Dell PowerEdge M1000e’s chassis management controller
(CMC). The CMC allows M-series blades to be managed individually or as groups, in single or
multiple chassis, and within a data center or in multiple geographically dispersed locations around
the globe without requiring an agent or additional hardware. PowerEdge M-series blade servers use
the redundant power, cooling, and networking infrastructure provided by the M1000e blade
enclosure, which is exceptionally easy to deploy and manage and maximizes power and cooling
efficiency.

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, E5-2600v2 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.
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.
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.

5Memory
More memory options are available than ever before with the Dell PowerEdge M620 —greater
capacities, higher frequencies, and more flexibility. The M620 supports up to 768GB of memory and
speeds up to 1866MT/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 that 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 UDIMM and RDIMM technologies, the M620 supports load
reduced DIMMs (LRDIMMs), which use a buffer to reduce memory loading and allow for greater
density, allowing for the maximum platform memory capacity.

Memory configurations
The M620 server supports flexible memory configurations ranging from capacities of 4GB to 768GB
(using 32GB DIMMs), and up to 12 DIMMs per processor (up to 24 DIMMs in a dual-processor
configuration). Each processor has four memory channels, with each channel supporting up to
three DIMMs.
Memory capacity options
The M620 is available in the following memory capacity options:
24-DIMM capacity: uses a 57mm heatsink and is recommended for use with processors of 95W
or less
20-DIMM capacity: uses a 77mm heatsink for cooling efficiency and is recommended for use
with 115W and 130W processors
16-DIMM capacity: uses a 97mm heatsink to support the higher ambient temperatures of Dell
Fresh Air configurations

20 PowerEdge M620 Technical Guide
Flexible memory configuration
The M620 supports a flexible memory configuration according to the following 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 M620:
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 and population, see the Dell PowerEdge M620
Systems Owner’s Manual on Dell.com/Support/Manuals.
Memory speed
The M620 supports memory speeds of 1866MT/s, 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 system runs 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 8 lists the memory configuration and performance details for the M620, based on the
population of the number and type of DIMMs per memory channel.
