Supported Memory

The PowerEdge R940 supports up to 48 DIMM slots, with up to 6 TB of memory and speeds up to 2666 MT/s. Supported DIMMs are
registered (RDIMMs) and load reduced (LRDIMMs) DIMMs which uses a buer to reduce memory loading and provide greater density
allowing maximum memory capacity.

Memory speed

The PowerEdge R940 supports memory speeds of 2666 MT/s, 2400 MT/s, and 1866 MT/s depending on the DIMM types installed and
congured. All memory on all of the processors and channels run at the same speed and voltage. The operating speed of the memory is
determined by the maximum speed supported by the processor, the speed settings in BIOS, and the operating voltage of the system.

Memory congurations and population rules

The R940 supports exible memory congurations ranging from 8 GB (minimum) to 128 GB (maximum). The R940 supports up to 12
DIMMs per processor or 24 DIMMs in a dual-processor and 48 DIMMs in a quad-processor conguration. Each R940 has 6 memory
channels per processor, with each channel supporting up to 2 DIMMs.

The R940 server support exible memory conguration according to the following population rules:

• If DIMMs of dierent speeds are mixed, all channels across all processors operate at the slowest DIMM's common frequency.

• DIMM type:

• All DIMMs must be DDR4 RDIMM and LRDIMM

• Only one type of DIMM is allowed per system-RDIMM, or LRDIMM. They cannot be mixed.

• DIMMs with dierent data width (x4 and x8 data width) can be mixed.

• The largest DIMM capacity is placed rst (slot A1 rst, then A2 and so on). The second CPU mirrors the rst CPU population rule.

• Maximum of two dierent capacity DIMMs are allowed in the system.

• Maximum of two dierent rank DIMMs are allowed in the system.

Supported Memory 17

Memory RAS features

Reliability, Availability, and Serviceability (RAS) features help keep the system online and operational without signicant impact to
performance, and decreases data loss and crashing issues. RAS helps in rapid and accurate diagnosis of system faults.

Table 8. Supported RAS features

Feature Description

Dense conguration optimized prole Increased memory reliability can be a result from this selectable

platform prole 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 (SDDC) 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 specic failing DIMM

channel pair, thereby enabling the user to replace only the failed
DIMM pair.

Memory mirroring 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 intra-socket 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, they are
moved to the spare area while the operating system is running to
prevent the errors 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.

Thermal and acoustics

Thermal management of PowerEdge R940 delivers high performance for the right amount of cooling to components at the lowest fan
speeds across a wide range of ambient temperatures from 10°C to 35°C (50°F to 95°F) and to extended ambient temperature ranges
(see Environmental Specications) . The benets to you are lower fan power consumption (lower server system power and data center
power consumption) and greater acoustical versatility. The PowerEdge R940 is quiet enough to be used in an oce environment in typical
and minimum congurations.

Thermal design

The thermal design of the PowerEdge R940 reects the following:

• Optimized thermal design: The system layout is architected for optimum thermal design.

• System component placement and layout are designed to provide maximum airow coverage to critical components with minimum
expense of fan power.

• Comprehensive thermal management: The thermal control system regulates the fan speed based on several dierent responses from all
system- component temperature sensors, as well as inventory for system congurations. Temperature monitoring includes components
such as processors, DIMMs, chipset, the inlet air ambient, hard disk drives, NDC, and GPU.

• Open and closed loop thermal fan speed control: Open loop thermal control uses system conguration to determine fan speed based on
inlet air ambient temperature. Closed loop thermal control method uses feedback temperatures to dynamically determine proper fan
speeds.

• User-congurable settings: With the understanding and realization that every customer has unique set of circumstances or
expectations from the system, in this generation of servers, we have introduced limited user- congurable settings residing in the
iDRAC9 BIOS setup screen. For more information, see the PowerEdge R940 Owner’s Manual on Dell support.

• Cooling redundancy: The R940 allow N+1 fan redundancy, allowing continuous operation with one fan failure in the system.

Acoustical design

The acoustical design of the PowerEdge R940 reects the following:

• Versatility: The R940 saves power draw in the data center but are also quiet enough for oce environment in typical and minimum
congurations. You may nd that the system is suciently quiet where the sound it emits blends into the environment.

• Adherence to Dell’s high sound quality standards: Sound quality is dierent from sound power level and sound pressure level in that it
describes how humans respond to annoyances in sound, like whistles and hums. One of the sound quality metrics in the Dell
specication is prominence ratio of a tone.

• Noise ramp and descent at boot-up from power o: Fan speeds and noise levels ramp during the boot process (from power- o to
power- on) in order to add a layer of protection for component cooling in the event that the system were not to boot properly. In order
to keep the boot-up process as quiet as possible, the fan speed reached during boot-up is limited to about half of full speed.

• Noise level dependencies: If acoustics is important to you, several conguration choices and settings are important to consider:

• For lower acoustical output, use a small number of lower rotational- speed SATA hard drives, nearline SAS hard drives, or non-

rotational devices like SSDs. 15k hard drives generate more acoustic noise than that of lower rotational- speed hard drives, and
noise increases with number of hard drives.

• Fan speeds and noise may increase from baseline factory congurations if certain proles are changed by the user or the system

congurations are updated. The following is a list of items that impact fan speeds and acoustical output:

26

Power, thermal, and acoustics

• iDRAC9 BIOS settings: Performance Per Watt (DAPC or OS) may be quieter than Performance or Dense Conguration (iDRAC
Settings > Thermal > Max. Exhaust Temperature or Fan speed oset).

• The quantity and type of PCIe cards installed: This aects overall system acoustics. Installation of more than two PCIe cards
results in an increase in overall system acoustics.

• PCIe controller-based SSD drives: Drives such as Express ash drives and Fusion- IO cards require greater airow for cooling,
and result in signicantly higher noise levels.

• Systems with an H330 PERC: This conguration may be quieter than those with an H730P PERC with battery backup.
However, higher noise levels result when a system is congured as non-RAID.

• Hot spare feature of power supply unit: In the system default setting, the Hot Spare Feature is disabled; acoustical output from
the power supplies is lowest in this setting.

Power, thermal, and acoustics 27

Rack Rails

The rail oerings consist of sliding rails only.

The sliding rails allow the system to be fully extended out of the rack for service. There is also an optional Cable Management Arm (CMA)
and optional Strain Relief Bar (SRB).

Figure 7. Sliding rails with optional CMA and optional SRB

One key factor in selecting the proper rails is identifying the type of rack in which they will be installed. Both the sliding rails and the static
rails support tool-less mounting in 19”-wide, EIA-310-E-compliant square hole and unthreaded round hole 4-post racks. Both also support
tooled mounting in threaded hole 4-post racks, but only the static rails, as the more universal solution, support mounting in 2-post (Telco)
racks.

NOTE: Screws are not included in either kit due to the fact that threaded racks are oered with a variety of thread designations.

Users must therefore provide their own screws when mounting the rails in threaded racks.

NOTE: Screw head diameter for the sliding rails must be 10 mm or less.

Cable Management Arm (CMA) and Strain Relief Bar
(SRB)

The optional cable management arm (CMA) and Strain Relief Bar (SRB) organizes and secures the cords and cables exiting the back of the
server. The CMA supports up to medium size cable loads and unfolds to allow the server to extend out of the rack without having to

9

28 Rack Rails

detach the cables. The SRB is a bar that supports large cable loads and also allows the server to extend out of the rack without having to
detach the cables if cable service loops are created.

Some key features of the CMA include:

• Large U-shaped baskets to support dense cable loads

• Open vent pattern for optimal airow

• Ability to be mounted on either side by simply swinging the spring-loaded brackets from one side to the other

• Utilizes hook-and-loop straps rather than plastic tie wraps to eliminate the risk of cable damage during cycling

• Includes a low-prole xed tray to both support and retain the CMA in its fully closed position

• Both the CMA and the tray mount without the use of tools via simple and intuitive snap-in designs

Some key features of the SRB include:

• Sturdy bar that supports large cable loads.

• Controls stresses on connectors.

• Utilizes hook-and-loop straps rather than plastic tie wraps to make securing cables quick and eliminates the risk of cable damage.

• Cables can be segregated into discrete, purpose specic bundles.

• Attaches to the rails without the use of tools via simple and intuitive latching design.

The CMA can be mounted to either side of the sliding rails without the use of tools or the need for conversion. However, it is recommended
that it be mounted on the side opposite to the power supplies to allow easier access to the power supplies and rear hard drives (if
applicable) for service or replacement.

Rack Installation

The sliding rails are a "drop-in" design. This means that the system is installed vertically into the rails by inserting the standos on the sides
of the system into the "J-slots" in the inner rail members with the rails in the fully extended position. As with all 2U systems, a minimum of
two people are required in order to properly install the system in the rails.

Rack Rails

29

NOTE: The 2U system requires two people for installation due to its heavier weight.

Installing 14G Systems in Sliding Rails

To install the 14G system in sliding rails:

1 Pull the inner slide rails out of the rack until they lock into place.

• Hold the system by its front and back ends and tilt the front end upward slightly.

• Check the window on the sides of both rails to conrm that the heads of the standos are visible before adjusting or releasing
your grip on the back end of the system.

• Use your free hand to hold the rail against the side of the chassis if needed as the system is rotated downward into the remaining
J-slots.

2 Locate the rear rail stando on each side of the system and lower them into the rear J-slots of the slide assembly.
3 Rotate the system downward until all the rail standos are seated in the J-slots.
4 Push the system inward until the lock levers click into place. Press the slide-release lock buttons on both rails and slide the system into

the rack.

Agent-free management

As Dell EMC PowerEdge servers have embedded server lifecycle management, in many cases, there is no need to install an OpenManage
systems management software agent into the operating system of a PowerEdge server. This greatly simplies and streamlines the
management footprint.

Agent-based management

Most systems management solutions require pieces of software, called agents, to be installed on each node in order to be managed within
the IT environment. Additionally, the same agent is often used as a local interface into the hardware health and may be accessed remotely
as a management interface, typically referred to as a one-to-one interface. For customers that continue to use agent-based solutions, Dell
provides OpenManage Server Administrator.

OpenManage consoles

The central console in a systems management solution is often referred to as the one-to-many console. The central console provides a
rapid view and insight into the overall health of all systems in the IT environment. The Dell EMC systems management portfolio includes
several powerful consoles, depending upon your needs, including the following:

• Dell OpenManage Essentials—OpenManage Essentials (OME) is a systems management console that provides a comprehensive view
of Dell systems, devices, and components in an enterprise network. It is used to monitor Dell PowerEdge servers, EqualLogic and
PowerVault storage, and PowerConnect™ switches; to update and congure Dell servers; and to create asset reports. OpenManage
Essentials also communicates health status alerts for Dell servers, storage, and network devices to the Dell KACE™ K1000 service desk.
OpenManage Essentials is available as a no-charge software download from Dell.com/Support. When connected through OME, you
can use Dell OpenManage Mobile (OMM) to securely perform a subset of data center monitoring and remediation tasks from a mobile
device.

• OpenManage Power Center—Dell’s power management solution, the Dell OpenManage Power Center (OMPC) management console,
provides increased visibility to power consumption, anomalies, and utilization through ne-grained instrumentation. This enables

increased control, improved rack density, faster response times, greater accuracy, and broader decision-making intelligence than would
otherwise be possible. When used with a suitably licensed PowerEdge server (with a Dell iDRAC Enterprise license), OMPC leverages
Intel Node Manager technology for platform-level power reporting and capping of Intel chipsets. Power Center then communicates
with iDRAC to provide node, rack, row or data-center level aggregation of power-management data, as well as execution of control
policy — making it easy for IT professionals to identify areas to gain eciencies and cut wasteful costs.

OpenManage systems management tools, utilities and
protocols

OpenManage systems management tools and utilities consist of the following:

• Dell EMC Repository Manager: The Dell EMC Repository Manager (RM) is a stand-alone GUI-based productivity tool that helps
simplify the process of managing downloads and baseline BIOS, rmware and driver updates. Repository Manager can create
deployment disks as well as create and manage customized repositories.

• Dell EMC Update Packages: The Dell EMC Update Packages (DUP) is a self-contained executable in a standard package format that
updates a software element on a Dell server such as the BIOS, a driver, rmware and other software updates.

• Dell EMC OpenManage Deployment Toolkit: The Dell EMC OpenManage Deployment Toolkit (DTK) is a CLI-based tool that includes a
set of utilities for conguring and deploying Dell PowerEdge systems, and can be used to build scripted, unattended OS installations to
deploy large numbers of servers in a reliable fashion.

• RACADM: The RACADM command-line utility provides a scriptable interface that allows you to locally or remotely congure iDRAC7.

• IPMITool: IPMITool includes scriptable console application programs used to control and manage remote systems using the IPMI version

1.5 and later protocol.

• Web Services for Management (WSMAN): WSMAN is a SOAP-XML–based protocol for exchanging system management
information. Dell's implementation provides remote management capabilities through a secure and standards-based Web Services–
Management (WS-MAN) interface to PowerEdge servers and blade server node chassis.

Integration with third-party consoles

OpenManage provides integration with several leading third-party consoles, including:

• OpenManage Integration Suite for Microsoft System Center—This suite helps you further streamline, automate and simplify your
most essential IT management tasks. For more information, visit http://www.dell.com/learn/us/en/04/solutions/dcsm-microsoft-

system-center.

• OpenManage Integration for VMware vCenter—This plug-in allows IT administrators to monitor, provision, and manage the physical
PowerEdge server hardware and rmware from a dedicated menu accessed through the VMware vCenter console using the same role­based access control model as vCenter, combining physical server management. For more information, visit http://www.dell.com/

learn/us/en/04/virtualization/management-plug-in-for-vmware-vcenter.

• BMC Software—Dell EMC and BMC Software work together to simplify IT by ensuring tight integration between Dell EMC server,
storage, and network management functionality and the BMC Software process and data center automation products.

OpenManage connections with third-party consoles

OpenManage Connections gives you an easy path to adding support for third-party devices, so you can continue to use your existing
management tools while easily adding server systems to your existing IT environment. Integrate new systems at your own pace. Manage
new servers and storage with your legacy management tools, while extending the useful life of your existing resources. With OpenManage
Connections you can add monitoring and troubleshooting to your IT infrastructure.

• OpenManage Connection for Nagios

• OpenManage Connection for Oracle

• OpenManage Connection for HP

• OpenManage Connection for IBM

• OpenManage Connection for CA

OpenManage systems management

Server management operations

OpenManage systems management is centered on automating the server management lifecycle — deploy, update, monitor and maintain.
To manage an infrastructure properly and eciently, you must perform all of these functions easily and quickly. iDRAC9 with Lifecycle
Controller technology provides you with these intelligent capabilities embedded within the server infrastructure. This allows you to invest
more time and energy on business improvements and less on maintenance. Figure 16 illustrates the various operations that can be
performed during the server’s lifecycle.
