Memory speed

The R940xa support memory speeds of 2666MT/s, 2400MT/s, 2133MT/s, and 1866MT/s depending on the DIMM types installed and the conguration. All memory on all processors and channels run at the same speed and voltage. By default, this speed will be the highest speed supported by the CPU and the DIMMs. For example both DIMMs and CPUs must be capable of running at 2666MT/s in order for memory to run at 2666MT/s (specic CPU / DIMM conguration required). CPU SKUs in the Platinum category support up to 2666MT/s memory speed while CPU SKUs in Gold and Silver category support up to 2400MT/s memory speed. he 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

The table below lists the memory conguration and performance details of the PowerEdge R940xa, based on the quantity and type of DIMMs per memory channel:

Memory conguration

The R940xa servers support exible memory congurations ranging from capacities of 8GB (minimum) to 6144 GB(maximum). The R940xa support up to 12 DIMMs per processor (up to 48 DIMMs in a four- processor conguration). Each server has 6 memory channels per processor, with each channel supporting up to 2 DIMMs.

Both systems support a exible memory conguration according to the following population rules:

• Speed: If DIMMs of dierent 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: RDIMM, or LRDIMM. These types cannot be mixed.

• DIMMs with dierent data widths can be mixed. For 14G, DIMMs with x4 and x8 data widths are supported and mixing is allowed.

• Can mix DIMMs with dierent capacities.

– Population rules require the largest capacity DIMM be placed rst (slot A1 populated rst, then A2, and so on... The second

CPU mirrors the rst CPU population).

– Maximum of two dierent capacity DIMMs allowed in a system

• Can mix DIMMs with dierent ranks.

– Maximum of two dierent rank DIMMs allowed in a system

Memory RAS features

Reliability, Availability, and Serviceability (RAS) features help keep the system online and operational without signicant impact to performance, and can decrease data loss and crashing due to errors. RAS aids in rapid, accurate diagnosis of faults which require service. The table below describes the memory RAS features supported for the PowerEdge R940xa:

Table 10. 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.

Feature Description

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.

NOTE: If a system with AC 1100 W PSUs operate at low line 100-120 Vac, then the power rating per PSU is derated to 1050 W.

NOTE: If a system with AC 1600 W PSUs operate at low line 100-120 Vac, then the power rating per PSU is derated to 800 W.

NOTE: If a system with AC 2000 W PSUs operate at low line 100-120 Vac, then the power rating per PSU is derated to 1000 W.

The PowerEdge R940xa support up to 2 AC or DC power supplies with 1+1 redundancy, auto sensing, and auto-switching capability.

If two PSUs are present during POST, a comparison is made between the wattage capacities of the PSUs. In the event that the PSU wattages don't match, the larger of the two PSU's is enabled. Also, there is a PSU mismatch warning displayed in BIOS, iDRAC, or on the System LCD.

If a second PSU is added at run-time, in order for that particular PSU to be enabled, the wattage capacity of the rst PSU must equal the second PSU. Otherwise, the PSU will be agged as unmatched in iDRAC and the second PSU will not be enabled

Thermal and acoustics

The system's thermal management delivers high performance through optimized cooling of 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. These optimizations result in lower fan power consumption which translate to lower system power and data center power consumption.

Thermal design

The thermal design of the system 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 minimal expense of fan power.

• Comprehensive thermal management: The thermal control system regulates the system fan speeds based on feedback from system component temperature sensors, as well as for system inventory and subsystem power draw. Temperature monitoring includes components such as processors, DIMMs, chipset, system inlet air ambient, hard disk drives, NDC, and GPU.

• Open and closed loop fan speed control: Open loop fan control uses system conguration to determine fan speed based on system inlet air temperature. Closed loop thermal control uses temperature feedback to dynamically adjust fan speeds based on system activity and cooling requirements.

• User-congurable settings: With the understanding and realization that every customer has a unique set of circumstances or expectations from the system, in this generation of servers, we have introduced limited user-congurable settings in the iDRAC9 BIOS setup screen. For more information, see the Dell EMC PowerEdge system Installation and Service Manual on Dell.com/ Support/Manuals and “Advanced Thermal Control: Optimizing across Environments and Power Goals” on Dell.com.

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

• Environmental Specications: The optimized thermal management makes the R940xa reliable under a wide range of operating environments.

Expanded operating temperature restrictions

• The operating temperature is for a maximum altitude of 950 m for fresh air cooling

• No cold start-ups below 5°C due to hard drive constraints

• Apache Pass DIMM, NVDIMM, PCIeSSD and NVME are not supported

• GPGPU conguration are not supported

• LRDIMM > 32 GB are not supported in x4 socket congurations

• Redundant power supply units are required

• Non Dell qualied peripheral cards and /or peripheral cards greater than 25 W are not supported

Acoustical design

The acoustical design of the PowerEdge R940xa reect the following:

• Versatility: The R940xa save you 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 EMC'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 EMC 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:

• 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.

• Using a GPU card: This 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.

Rack rails

Stab-in/Drop-in sliding rails are oered for the R940xa. The R940xa does not have a static rail option.

Sliding rails features summary

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 Dell EMC 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 EMC provides OpenManage Server Administrator.

Dell EMC 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 EMC OpenManage Essentials

OpenManage Essentials is the one-to-many management console for monitoring Dell HW infrastructure including server, storage and networking, as well as for lifecycle management of PowerEdge servers. It support Windows, Linux, VMware, and HyperV environments. OME provides a simple and easy interface for system administrators to maximize the uptime and health of Dell systems. It helps to

• Monitor health status and events for PowerEdge servers, EqualLogic or MD series storage, and PowerConnect and Force 10 switches.

• Provide hardware-level control and management for PowerEdge server, blade system, and internal storage arrays.

• Link and Launch element management interfaces, such as, iDRAC, CMC, EQL group manager etc

• Integrate with the following Dell solutions:

– Dell Repository Manager : Builds customized server update baselines that OpenManage Essentials can use.

– OpenManage Power Center : Optimize power consumption in the servers.

– SupportAssist : Enables automatic hardware failure notication to be sent securely to Dell technical support for intelligent

analysis and diagnosis to optimize availability and reduce manual intervention. This solution is available as part of Dell ProSupport and ProSupport Plus at no additional cost.

• Provide REST interface API support for 3rd Party Integration.

• Manage Server Conguration - it is a fee-based license available on Dell’s 14th generation of PowerEdge servers with iDRAC Enterprise or iDRAC Express licenses. The key features include the following:

– Congure a server or chassis using a template and deploying an operating system on the PowerEdge bare metal servers.

– During a server operation, automatically detect and notify any server or chassis drift from a customer-dened baseline

conguration.

– Boot a system from a network-mounted ISO using iDRAC.

– Replicate of FN-IOM and M-IOA congurations within M1000e chassis.

– Support VLAN Management for FN-IOM and M-IOA.

• For more information, see delltechcenter.com/OME

OpenManage Mobile

OpenManage Mobile(OMM) is a software application that enables easy, convenient, and secure monitoring and management of PowerEdge servers remotely, or at-the-server. With OpenManage Mobile, IT Administrators can securely perform several data center monitoring and remediation tasks using an Android or iOS mobile device. The OpenManage Mobile app is available as a free software download from the Apple Store and the Google Play Store.

OMM can also monitor and manage PowerEdge servers through a OpenManage Essentials console or by directly accessing the server’s iDRAC.

The OpenManage Essentials console can be accessed through OpenManage Mobile over a secure IP network. This allows you to monitor all devices managed by OpenManage Essentials such as Dell EMC servers, storage, networking, rewall, and supported third party devices.

If you are remote, you can access iDRAC over a secure IP network. If you are at-the-server, an iDRAC can be accessed directly by tapping an NFC-enabled android mobile device on a PowerEdge “Quick Sync” bezel to perform several basic bare-metal conguration tasks such as assigning an IP address, and changing server credentials or the boot order.

Key Features of OpenManage Mobile (When connected through OpenManage Essentials console):

• Connect to multiple servers which have OME installed, from a single mobile device.

• Connect to multiple servers individually through the iDRAC interface.

• Receive critical alert notication on your mobile device as they arrive into your OpenManage Essentials management console.

• Acknowledge, forward, and delete alerts from your mobile device.

• Browse through device details, rmware inventory, and event logs of individual systems.

• Perform several server management functions such as power-on, power cycle, reboot, and shutdown from the mobile application.

Key Features of OpenManage Mobile (When connected through iDRAC):

• Connect to any 14th gen, 13th gen, or 12th gen server remotely

• Access 14th gen rack or tower server through Quick Sync 2 module.

• Assign IP address, change credentials, and update common BIOS attributes for Bare Metal Conguration

• Congure one server manually, or multiple servers simultaneously through a template.

• Browse server details, health status, hardware & rmware inventory, networking details, and System Event or LC logs. Share this information easily with other IT Administrators.

• Access SupportAssist reports, Last Crash screen and video (PowerEdge 14th gen servers)

• Access Virtual Console (and reduce the need for crash carts).

• Power On, Shut down, or Reboot your server from anywhere.

• Run any RACADM command

OpenManage Power Center

OpenManage Power Center is a one-to-many application that can read power usage and thermal readings information from Dell EMC servers, Power Distribution Units (PDU), and Uninterruptible Power Supplies (UPS). It can aggregate this information into rack, row, and room-level views. On servers with iDRAC Enterprise license, you can also cap or throttle the power consumption. You may need to set power caps to reduce the power consumption due to external events such as brownouts or failures of data-center cooling devices. You can also use power capping to safely increase the numbers of servers in a rack to match the power that is provisioned for that rack.

For more information, see OpenManage Power Center User’s Guide available at Dell.com/openmanagemanuals.

Dell EMC OpenManage systems management tools, utilities and protocols

Dell EMC OpenManage systems management tools and utilities consist of the following:

Dell EMC Repository Manager:

Dell EMC Repository Manager (DRM) is an application that helps you to:

• Identify the updates that are relevant to the systems in your data center.

• Identify and notify when updates are available.

• Package the updates into dierent deployment format.

To automate the creation of baseline repositories, DRM provides advanced integration capabilities with iDRAC/LC, OpenManage Essentials, Chassis Management Controller, OpenManage Integration for VMware vCenter and OpenManage Integration for Microsoft System Center (OMIMSSC). Also, DRM packages updates into custom catalogs that can be used for deployment.

Dell EMC Repository Manager can create the following deployment tools:

• Custom catalogs

• Lightweight deployment pack

• Bootable Linux ISO

• Custom Server Update Utility (SUU)

For more information, see Dell EMC Repository Manager User’s Guide available at Dell.com/support/manuals.

Dell Update Packages

Dell Update Packages (DUP) is a self-contained executable supported by Microsoft Windows or Linux that updates a component on a server and applications like OMSA, iSM, and DSET.

DUPs can be executed in GUI or in CLI mode.

For more information, see Dell EMC Update Packages User’s Guide available at www.delltechcenter.com/DSU.

Dell Remote Access Controller Administration (RACADM) CLI

The RACADM command-line utility provides a scriptable interface to perform inventory, conguration, update, and health status check of PowerEdge servers. RACADM operates in multiple modes:•

• Local — supports running RACADM commands from the managed server’s operating system.

• SSH or Telnet — known as Firmware RACADM; is accessible by logging in to iDRAC using SSH or Telnet

• Remote — supports running RACADM commands from a remote management station such as a laptop or desktop.

RACADM is supported by the iDRAC with Lifecycle Controller and by the Chassis Management Controller of the M1000e, VRTX and FX2 modular systems. Local and Remote RACADM is supported on Windows Server, Windows clients, and on Red Hat, SuSe and Ubuntu Linux.

For more information, see the RACADM Command Line Reference Guide for iDRAC and CMC available at Dell.com/support/

manuals.

iDRAC with Lifecycle Controller Embedded Management APIs

iDRAC with Lifecycle Controller provides a range of standards-based applications programming interfaces (APIs) that enable scalable and automated management of PowerEdge servers. Standard systems management APIs have been developed by organizations such as the Institute of Electrical and Electronics Engineers (IEEE) and Distributed Management Task Force (DMTF). These APIs are

widely used by commercial systems management products and by custom programs and scripts developed by IT sta to automate management functions such as discovery, inventory, health status checking, conguration, update, and power management. The APIs supported by iDRAC with Lifecycle Controller include:

• Redsh - In 2015, the DMTF Scalable Platforms Management Forum published Redsh, an open industry-standard specication and schema designed to meet the needs of IT administrators for simple, modern, and secure management of scalable platform hardware. Dell is a key contributor to the Redsh standard, acting as co-chair of the SPMF, promoting the benets of Redsh, and working to deliver those benets within industry-leading systems management solutions. Redsh is a next generation management standard using a data model representation inside a hypermedia RESTful interface. The data model is dened in terms of a standard, machine-readable schema, with the payload of the messages expressed in JSON and the OData v4 protocol.

• WSMan -The Web Services For Management (WSMan) API, rst published by the DMTF in 2008, is the most mature and robust API provided by iDRAC with Lifecycle Controller. WSMan uses a Simple Object Access Protocol (SOAP) with data modeled using the Common Information Model. WSMan provides interoperability between management applications and managed resources, and identies a core set of web service specications and usage requirements that expose a common set of operations central to all systems management.

• IPMI - The Intelligent Platform Management Interface (IPMI) is a message-based, hardware-level interface specication that can operate over both LAN and serial interfaces. IPMI is supported broadly by server vendors, systems management solutions, and open source software.

• SNMP - The Simple Network Management Protocol (SNMP) helps in standardizing the management of network devices. SNMP allows commercial management consoles created for monitoring network switches and routers to also monitor X86 severs. SNMP is primarily used to deliver event messages to alert administrators of problems on their systems but can also be used to discover, inventory and congure servers.

To assist automating system management tasks and simplify API integration, Dell provides PowerShell and Python libraries and script examples utilizing the WSMan interface. The iDRAC with LC pages of Dell Techcenter oer a library of technical white papers detailing the use of the embedded management APIs. For more information, see delltechcenter.com/iDRAC and delltechcenter.com/LC.
