5 Memory 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 1.5TB of memory (48 DIMM slots) and speeds of up to 1600MT/s, providing high performance in a variety of applications.
The R820 supports the DIMMs listed in Table 8. For the latest information on supported memory, visit Dell.com/PowerEdge. Table 8.

Memory RAS features 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 9 describes the RAS features supported on the R820. Table 9.
6 Storage 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 SSDs 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 through the hot-plug drive bay.
Express Flash drives 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.
Controller Description Features RAID modes Form factor supported PERC H710P Internal Eight-port, internal 6Gb/s PCIe RAID controller that supports up to 32 SATA and SAS hard drives or SSDs Includes 1GB NV DDR3 cache, premium performance and feature set, security SED/EKMS, and SSD as cache 0, 1, 10, 5, 50, 6, 60 Integrated mini-type and 1 adapter-type Premium performance PERC H710 Internal Eight-port, internal 6Gb/s PCIe RAID controller that supports up to 32 SATA and SAS hard drives or SSDs Incl
7 Networking and PCIe The Dell PowerEdge R820 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0 capable expansion slots. Dell Select Network Adapters, Dell’s network daughter cards, let you choose the right network fabric without using up a valuable PCI slot. Pick the speed, technology, vendor and other options such as switch independent partitioning, which lets you share and manage bandwidth on 10GbE connections.

8 Power, thermal and acoustics 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 Description Active power management 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 iDRAC7 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. Figure 8. 750W power supply unit The PowerEdge R820 supports up to two AC-DC or DC-DC power supplies with 1 + 1 redundancy, auto-sensing and auto-switching capability. Dell PSUs have achieved Platinum and Titanium efficiency levels as shown in Table 17. Table 17. Power supply efficiency Efficiency targets by load Form factor Redundant 86mm Output Class 10% 20% 50% 100% 750W AC Platinum 82.0% 90.0% 94.0% 91.
User-configurable settings: An R820 thermal control design target is to minimize the contribution of fan power to overall system power. However, with the understanding and realization that every customer has a unique set of circumstances or expectations of the system, in this generation of servers, we are introducing limited user-configurable settings in the iDRAC7 BIOS setup screen. For more information, see the Dell PowerEdge R820 Owner’s Manual on Dell.
Table 18 details the acoustical performance for the R820. Table 18.
9 Rack rails and cable management The sliding and static rail systems for the Dell PowerEdge R820 provide tool-less support for fourpost racks with square or unthreaded round mounting holes. Both rail systems also support tooled mounting in four-post threaded racks, and the static rails support tooled mounting in two-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. Figure 10. Static rails 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 four-post racks.
Cable management arm 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.
10 Operating systems and virtualization The Dell PowerEdge R820 supports a wide range of industry-standard operating systems and virtualization software. Supported operating systems Table 20 lists the primary operating systems supported on the R820. For the latest information on supported operating systems, see Dell.com/OSsupport. Table 20. Primary operating system support Operating System Platform Edition x32 x64 N/A x64 N/A Red Hat Enterprise Linux 6.
Support of the operating systems listed in Table 21 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. Table 21.
11 Dell OpenManage systems management 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.
OpenManage systems management 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. iDRAC7 with Lifecycle Controller 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.

Agent-free 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. Dell consoles The central console in a systems management solution is often referred to as the one-to-many console.
