14 PowerEdge M820 Technical Guide
The Dell PowerEdge M820 features the Intel Xeon processor E5-4600 product family, offering 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. 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 E5-4600 product family not only adds new features, but also improves upon many features of the predecessor Intel Xeon processor series. A summary of what’s new and improved includes the following:
Up to two additional cores and up to 8MB more last level cache
More memory—16 more DIMMs than previous-generation of full-height blade servers with support for up to 32GB DIMMs, increasing memory capacity up to 1.5TB
Intel Integrated I/O has support for up to 80 lanes of PCIe 3.0, which can reduce latency
Faster connections are provided throughout the system with support for DDR3 1600MT/s
memory and 8.0GT/s QPI
Intel 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
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 that are integral to many technical, financial,
and scientific computing problems
Intel Turbo Boost Technology 2.0 delivers up to double the boost than the previous-generation

Flexible memory configurations are supported on the M820, ranging from capacities of 2GB to
1.5TB. The M820 supports up to 12 DIMMs per processor (up to 48 DIMMs in a four-processor configuration). Each processor has 4 memory channels, with each channel supporting up to 3
DIMMs.
The M820 supports a flexible memory configuration, according to the following 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 is allowed per system: RDIMM or LRDIMM. These types cannot be mixed.
The following additional memory population guidelines apply to the M820:
Up to two quad-rank (QR) DIMMs and up to three dual-rank (DR) or single-rank (SR) DIMMs may be populated per channel. Although an LRDIMM is physically a QR DIMM, logic on the LRDIMM can make it appear as a DR DIMM to the system, allowing up to three LDRIMMs 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.
For more information on memory configuration and population, see the
Dell PowerEdge M820
Systems Owner’s Manual
on Support.Dell.com/Manuals .
18 PowerEdge M820 Technical Guide
Memory speeds of 1600MT/s, 1333MT/s, 1066MT/s, and 800MT/s are supported on the M820, 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 system runs 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 8 lists the memory configuration and performance details for the M820, based on the
population of the number and type of DIMMs per memory channel.

19 PowerEdge M820 Technical Guide
Reliability, availability, and 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.
features supported on the M820.
Feature
Dense configuration optimized profile
Memory demand and patrol scrubbing
Recovery from single
DRAM device failure
(SDDC)
Failed DIMM isolation
Memory mirroring: intra-socket
Memory address parity protection
Memory sparing (rank)
Memory thermal throttling
Description
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.
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) 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.
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 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.
This feature provides the ability to detect transient errors on the address lines of the DDR channel.
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.
This feature helps to optimize power/performance and can also be used to prevent DIMMs from overheating.
For information on memory mirroring and sparing configurations, see the
Dell PowerEdge M820

The Dell PowerEdge M820 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0 capable mezzanine card slots. Dell Select Network Adapters, Dell’s network daughter cards, let you choose the right network fabric without using up a valuable mezzanine card slot. Pick the speed, technology, vendor, and other options such as switch independent partitioning, which let you share and manage bandwidth on 10GbE connections.
Installation of mezzanine cards requires an M1000e I/O module (IOM) of the same fabric technology to be installed in the corresponding fabric slot of the mezzanine to support data flow through that fabric or slot.
The Select Network Adapter family is purpose-built and includes flexible LAN on motherboard (LOM) card options for Dell PowerEdge 12 th generation servers. The Select Network Adapter form factor delivers the value of LOM integration with the system, including BIOS integration and shared port for manageability while providing the flexibility of a modular card.
The PowerEdge M820 supports two custom network daughter cards (NDC), as part of Select
Network Adapters family, to house the complete LOM subsystem. There are two form factors of

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.
35 PowerEdge M820 Technical Guide
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 Dell Chassis Management Controller (CMC) is a systems management hardware and software solution for managing multiple Dell blade chassis. The CMC is a hot-pluggable module inserted in the back of a Dell blade chassis. It provides a secure interface that enables an administrator to inventory, perform configuration and monitoring tasks, remote power on/off blades, and enable alerts for events on servers and components in the blade chassis.
The CMC uses iDRAC7 with Lifecycle Controller to perform management functions, such as opening a remote console session from the CMC interface.
The central console in a systems management solution is often referred to as the one-to-many console.
