The Dell PowerEdge T420 features the Intel Xeon processor E5-2400 product family, which offers an ideal combination of performance, power efficiency, and cost. These processors provide substantial performance and capacity for entry and mainstream workloads, as well as applications requiring significant memory and I/O scalability no matter what your constraint is—floor space, power, or budget. 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 E5-2400 product family provides the following features:

 2-socket processor design with power and dimensions optimized for density  Up to 8 execution cores per processor  Intel Hyper-Threading technology enables up to 16 computational threads  Micro-architecture on 32nm process for greater performance per watt  Support for more memory—4 additional DIMMs (up to 12 DIMM slots) and support for up to

32GB DIMMs increasing the memory capacity from 128GB to 384GB

 Integrated memory controller with 3 channels of DDR3 and 46-bit physical addressing facilitate

greater memory capacity

 Intel Integrated I/O has support for up to 24 lanes per socket of PCIe 3.0 links (for more

information on PCIe lanes, see the specifications in the System features section)

 Faster connections throughout the system with support for DDR3 1600MT/s memory and

8.0GT/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

 High bandwidth, low latency, bidirectional ring interconnect allows faster access to the 20MB

multi-banked last level cache

 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, which allows processor cores to run faster than the base

operating frequency if it's operating below power, current, and temperature specification limits, delivers up to double the boost than the previous generation

 Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

Flexible memory configurations are supported on the T420, ranging from capacities of 2GB to 384GB. The system supports up to 6 DIMMs per processor (up to 12 DIMMs in a 2-processor configuration). The T420 has 3 memory channels per processor, with each channel supporting up to 2 DIMMs.

The T420 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 can be used in a system. UDIMMs and RDIMMs cannot be

mixed.

The following additional memory population guidelines apply to the T420:

 Up to two quad-rank (QR), 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.

Description

Dense configuration optimized profile

Increased memory reliability can be a result from this selectable platform profile that adjusts parameters to reduce faults regarding refresh rates, speed, temperature and voltage

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 T420 based on the population of the number and type of DIMMs per memory channel.

*Although the T420 supports DIMM speeds of 800MT/s and 1066MT/s, you can only purchase this system with DIMM speeds of 1333MT/s and 1600MT/s on Dell.com.

RAS features help keep the system online and operational without significant impact to performance, and can decrease data loss and crashing due to errors. RAS aids in rapid, accurate diagnosis of faults that require service. Table 11 describes the RAS features supported on the T420.

Feature

Description

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

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

Memory mirroring: intra-socket

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 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, it is moved to the spare area while the operating system is running to prevent the error 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.

Dell PSUs have achieved Platinum efficiency levels as shown in Table 17.

Optimized thermal management makes the PowerEdge T420 cool and quiet. Benefiting from smart cooling fan speed control, the T420 can keep both high performance and good acoustics 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 Table 26). Operating environments for the T420 can vary from the data center to general-use spaces. In a typical configuration, the T420 is suitable for an open office environment.

Page 31

The thermal design of the PowerEdge T420 reflects the following:

 Multiple sensors are monitored for thermal feedback control: The PowerEdge T420

dynamically controls system cooling fan speed based on responses from component temperature sensors, including processors, hard disk drives, DIMMs, storage cards, and the inlet ambient temperature. Thermal control detects and responds to hardware configuration. Thermal management adjusts cooling according to what the system really needs, and draws lower fan power draw and generates lower acoustical noise levels than servers without such controls.

 Environmental specifications: The optimized thermal management makes the T420 reliable

under a wide range of operating environments as shown in the environmental specifications in Table 26. Many configurations are also compliant under expanded operating temperature environments, but a few are not.

The acoustical design of the PowerEdge T420 reflects the following:

 Quiet library acoustics: The PowerEdge T420 is quiet enough for an office setting when

minimally configured and for the office under the desk with a typical configuration.

 Adherence to Dell’s high sound quality standards: Sound quality is different from sound power

level and sound pressure level in that it describes how humans respond to annoyances in sound, like whistles, hums, and so on. One of the sound quality metrics in the Dell specification is prominence ratio of a tone, which is listed in Table 18.

 Configurable for low acoustics: The following are configuration considerations you should make

if acoustics is important to you:

- Storage devices: > Because hard drive noise scales with spindle speed, the quietest option for rotational

storage media is a 7200-rpm SATA drive. The loudest option is a 15k SAS drive.

> Solid-state drives are even quieter than rotational drives because they have no sound

associated with spinning.

> Noise levels increase with the quantity of hard drives; using fewer hard drives will have a

lower acoustical output.

- Impact of cards: > Quantity of PCIe cards: When more than two PCIe cards are installed, the system fan

speed/noise level will be higher.

> Types of PCIe cards: The fan speed/noise level will be higher if a GPU and PERC H710 are

installed.

- System Profile settings in BIOS and Thermal settings in iDRAC: Performance Per Watt is the quietest

option. Other options such as Performance Optimized or Dense Configuration require higher fan speeds, which produce higher acoustic levels.

- Hot spare feature of power supply unit: In system default setting, the hot spare feature is disabled;

acoustical output from the power supplies is lowest in this setting. If the feature is enabled and the system power loading is low, the power supply fan speed hence noise will be higher.

- RAID Setup with PERC H310: A system configured as non-RAID will have a higher noise level than a

system configured as RAID. With non-RAID, the temperature of the hard disk drives is not monitored, which causes the fan speed to be higher to ensure sufficient cooling resulting in higher noise level.

 Noise ramp and descent during bootup from power off: Fan speed noise levels ramp during the

boot process (from power off to power on) to add a layer of protection for component cooling in case the system does not boot properly. To keep the bootup process as quiet as possible, the fan speed reached during bootup is limited to about half of full speed.

The sliding rail system for the Dell PowerEdge T420 provides tool-less support for 4-post racks with square or unthreaded round mounting holes. Compared to the T610 sliding rails that required the use of adapter brackets, the sliding rails for the T420 now offer support for threaded hole racks with the ReadyRails II mounting interface.

The ReadyRails II sliding rails for the T420 support tool-less mounting in 19”-wide, EIA-310-E compliant square hole and unthreaded round hole 4-post racks. The rails also support tooled mounting in threaded hole 4-post racks and are available with or without the optional cable management arm (CMA).

The rails ship in the tool-less mounting configuration, but can be easily converted to the tooled configuration. The optional CMA can be mounted on either the left or right side of the sliding rails without the use of tools for fast and easy deployment. The T420 is backward compatible with the T610 rails and CMA. The T420 supports sliding rails only. Static rails are not supported. Mounting in 2-post racks is not supported.

Figure 9 shows the sliding rails with the CMA installed.

Table 19 lists the supported rack types for the T420.

Screws are not included in the kit due to the fact that threaded racks are offered with a variety of thread designations. Other factors to consider when deploying the T420 include the spacing between the front and rear mounting flanges of the rack, the type and location of any equipment

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 agentbased solutions, Dell provides OpenManage Server Administrator.

The Dell OpenManage Server Administrator (OMSA) agent gives you a comprehensive, one-to-one systems management solution for both local and remote servers and their storage. OMSA can help simplify single-server monitoring with a secure command-line interface (CLI) or Web-based management graphical user interface (GUI). It can also be used to view system configuration, inventory, health, and performance.

Because Dell 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 PowerEdge server. This greatly simplifies and streamlines the management footprint.

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 systems management portfolio includes several powerful consoles, depending upon your needs, including the following:

 Dell OpenManage Essentials— OpenManage Essentials (OME) is a recently released 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 configure

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 Support.Dell.com.

 Dell Management Console—Dell Management Console (DMC) offers sophisticated data center

management capabilities with comprehensive reporting features. DMC can perform basic hardware management and can manage operating systems and applications using various plug-ins from Symantec.

 Dell IT Assistant—Dell IT Assistant (ITA) is a console for managing Dell servers, storage arrays,

and other components distributed throughout a network. Dell IT Assistant allows for easy identification of system issues through alerts, helping to reduce system downtime. Systems administrators can easily monitor systems anywhere within their network using ITA. ITA is supported on the T420, however, enhanced functionality is now available with OpenManage Essentials.

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

 Dell Repository Manager—The Dell Repository Manager (RM) is a standalone GUI-based

productivity tool that helps simplify the process of managing downloads and baseline BIOS, firmware, and driver updates. Repository Manager can create deployment disks as well as create and manage customized repositories.

Page 42

 Dell OpenManage Server Update Utility—The Dell Server Update Utility (SUU) is a DVD-based

application for identifying and applying BIOS and firmware updates to your Dell PowerEdge servers.

 Dell OpenManage Systems Build and Update Utility—The Dell System Build and Update Utility

(SBUU) provides one-to-one and one-to-many deployment and single-server update capabilities in the pre-operating system environment.

 Dell Update Packages—The Dell 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, firmware and other software updates.

 Dell OpenManage Deployment Toolkit—The Dell OpenManage Deployment Toolkit (DTK) is a

CLI-based tool that includes a set of utilities for configuring 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 configure iDRAC7.

 IPMITool—IPMITool includes scriptable console application programs used to control and

manage remote systems using the IPMI version 1.5 and later protocol.

Dell OpenManage easily integrates with several leading third-party consoles, including:

 Dell Server Management Pack Suite for Microsoft System Center Operations

Manager (SCOM)—This suite of server management packs enables several functions through System Center Operations Manager, including in-band discovery and monitoring of racks and towers, out-of-band discovery and monitoring through iDRAC with Lifecycle Controller, as well as performance and advanced monitoring.

 Dell Lifecycle Controller Integration (DLCI) for Microsoft System Center Configuration

Manager (SCCM)—This pack contains Dell Lifecycle Controller Integration (DLCI), which integrates OpenManage functions in SCCM to manage the Dell PowerEdge servers, including auto-discovery, operating system deployment and configuration of hardware elements, (RAID, NIC, BIOS, iDRAC), OS and hypervisor agnostic updates, firmware management, and system viewer utilities.

 Dell Server PRO Management Pack for Microsoft System Center Virtual Machine

Manager (SCVMM)—This pack manages Dell physical servers and hosts of virtual machines (VMs) by using Microsoft System Center Operations Manager/System Center Essentials (SCOM/SCE) and System Center Virtual Machine Manager (SCVMM). It provides guidance for remedial actions based on alerts to best manage virtual machines and handle the impacts appropriately.

 Dell Management Plug-in for VMware vCenter—This plug-in allows IT administrators to monitor,

provision, and manage the physical PowerEdge server hardware and firmware from a dedicated Dell menu accessed through the VMware vCenter console using the same role-based access control model as vCenter, combining physical server management.

 BMC Software—Dell and BMC Software work together to simplify IT by ensuring tight integration

between Dell server, storage, and network management functionality and the BMC Software process and data center automation products.

Page 43

Dell OpenManage provides connections with many third-party consoles, including:

 Dell OpenManage Connection for Computer Associates Network and

Systems Management—This connection allows you to monitor PowerEdge servers and PowerVault storage arrays from within the Computer Associates Network and Systems Management (CA NSM) console.

 Dell OpenManage Connection for HP Operations Manager—This connection enables several

functions through HP Operations Manager, including auto-grouping, SNMP trap reception, global health monitoring, and a context-sensitive launch of OpenManage Server Administrator.

 Dell OpenManage Connection for IBM Tivoli Netcool/OMNIBus—This connection provides

event monitoring capabilities to monitor Dell PowerEdge servers and Dell EqualLogic systems. It allows event monitoring, automatic event correlation, and launching device consoles from the Netcool/OMNIbus console.

Dell OpenManage systems management is centered on automating the server management lifecycle—deploy, update, monitor, and maintain. To manage an infrastructure properly and efficiently, you must perform all of these functions easily and quickly. iDRAC7 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 11 illustrates the various operations that can be performed during the server’s lifecycle.

Table 24 lists the products that are available for one-to-one and one-to-many operations, and when they are used in the server’s lifecycle:
