The chassis design of the R820 is optimized for easy access to components and for airflow for effective and efficient cooling. The R820 supports up to 48 DIMMs, 4 processors, hot-plug redundant fans, and many other components and features described in this guide.
Table 4 lists the features on the R820 chassis. For additional information, see the Dell PowerEdge R820 Systems Owner’s Manual on Support.Dell.com/Manuals.
A useful feature included with Dell PowerEdge 12th generation servers is the Quick Resource Locator (QRL)—a model-specific Quick Response (QR) code that is located inside the R820 chassis cover (see Figure 6). Use your smartphone to access the Dell QRL app to learn more about the server.
Security feature Description Cover latch A tooled latch is integrated in the side cover to secure it to the rack chassis. Bezel An optional metal bezel is mounted to the chassis front to provide the Dell ID. A lock on the bezel is used to protect un-authorized access to hard drives. System status is viewable on the LCD screen when the bezel is installed. TPM The Trusted Platform Module (TPM) is used to generate/store keys, protect/authenticate passwords, and create/store digital certificates.
The Dell PowerEdge R820 features the Intel Xeon processor E5-4600 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.

More memory options are available than ever before with the Dell PowerEdge R820—greater capacities, higher frequencies, and more flexibility. The R820 supports up to 1.5 TB of memory (48 DIMM slots) and speeds of up to 1600 MT/s, providing high performance in a variety of applications.
The R820 supports the DIMMs listed in Table 9. For the latest information on supported memory, visit Dell.com. Capacity (GB) Speed (MT/s) Type Ranks per DIMM Data width SDDC support Voltage 2 1333 RDIMM 1 x8 Advanced ECC 1.35 2 1333 UDIMM 1 x8 Advanced ECC 1.35 2 1600 RDIMM 1 x8 Advanced ECC 1.5 4 1333 RDIMM 2 x8 Advanced ECC 1.35 4 1333 RDIMM 1 x4 All modes 1.35 4 1333 UDIMM 2 x8 Advanced ECC 1.35 4 1600 RDIMM 2 x8 Advanced ECC 1.
The R820 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.
Reliability, availability, serviceability (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 R820.
The Dell PowerEdge R820 supports extensive internal and external storage options, internal and external storage controllers, and different chassis and backplane options for a varied number of drives. Features such as Express Flash PCIe solid-state drives and CacheCade™ provide accelerated performance over previous technologies. Express Flash drives use PCIe lanes to connect directly to the processor and chipset and are easily accessible by hot-plug drive bay.
Express Flash drives use PCIe and SSD technologies to provide performance, scalability, and optimal serviceability. Accelerated performance with high IOPs is made possible without requiring processor resources or capturing DRAM. Also, Express Flash drives use a standardized 2.5-inch hot-plug form factor that saves critical PCIe slot space by moving drives from the back to the front of the system and allows a common management process for all drives. The PowerEdge R820 has an option to support up to four 2.

The R820 supports a variety of PCIe expansion cards. Table 16 lists the supported add-in NICs and HBAs.
Lower overall system-level power draw is a result of breakthrough system design. The Dell PowerEdge R820 server maximizes performance per watt through a combination of power and cooling, energy efficient technologies, and tools. Additionally, the PowerEdge R820 has an extensive collection of sensors that automatically track thermal activity, which helps regulate temperature thereby reducing server noise and power consumption.
Feature Active power management Description Intel Node Manager is an embedded technology that provides individual server-level power reporting and power limiting functionality. Dell offers a complete power management solution comprised of Intel Node Manager accessed through Dell iDRAC Enterprise and OpenManage Power Center that allows policy-based management of power and thermals at the individual server, rack and data center level. Hot spare reduces power consumption of redundant power supplies.
Figure 8 shows a 750W power supply unit extended from the R820 chassis. The PowerEdge R820 supports up to two AC-DC or DC-DC power supplies with 1 + 1 redundancy, auto-sensing, and auto-switching capability.

The sliding and static rail systems for the Dell PowerEdge R820 provide toolless support for 4-post racks with square or unthreaded round mounting holes. Both rail systems also support tooled mounting in 4-post threaded racks, and the static rails support tooled mounting in 2-post (Telco) racks as well for added versatility.
The static rails (shown in Figure 10) support a wider variety of racks than the sliding rails but do not support serviceability in the rack and are therefore are not compatible with the CMA. 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.
The optional CMA organizes and secures the cords and cables exiting the back of the server and unfolds to allow the server to extend out of the rack without having to detach the cables.
The Dell PowerEdge R820 supports a wide range of industry-standard operating systems and virtualization software. Table 22 lists the primary operating systems supported on the R820. For the latest information on supported operating systems, see Dell.com/OSsupport. Operating System Platform Red Hat Enterprise Linux 5.8 1 Red Hat Enterprise Linux 6.2 2 x32 x64 Edition N/A x64 N/A Red Hat Enterprise Linux 6.
Support of the operating systems listed in Table 23 is limited to a virtual environment as a guest operating system. Please contact the software vendor for additional support or questions about running the operating system in a virtualized environment.
Whether your IT environment consists of a few servers or a few thousand servers, Dell OpenManage systems management solutions provide comprehensive management for evolving IT environments. OpenManage is based on open standards and provides agent-based and agent-free server lifecycle management functionality for Dell PowerEdge servers. OpenManage solutions help you automate and streamline essential hardware management tasks.
The Dell OpenManage systems management portfolio includes powerful hardware and software management tools and consoles. OpenManage simplifies the lifecycle of deploying, updating, monitoring, and maintaining your Dell PowerEdge servers. The Integrated Dell Remote Access Controller 7 (iDRAC7) with Lifecycle Controller is the heart of Dell’s second generation of Dell PowerEdge server embedded management functionality.
Feature Function Electronic licensing Benefit Upgrades to iDRAC7 Express or iDRAC7 Enterprise by software licensing key and license portal (may require installation of hardware option for 300-500 series servers) Digital license installed in factory; free 30day trial versions are available; uses a license management portal versus paper-based licenses and simplifies license management.

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.
IPMITool—IPMITool includes scriptable console application programs used to control and manage remote systems using the IPMI version 1.5 and later protocol.
