1 System overview Introduction The Dell™ PowerEdge™ R420 is a 2- socket, 1U rack- mount server offering powerful performance and scalability in a dense 1U rack form factor. It is an excellent fit for compute- intense applications and high- performance computing (HPC) workloads. The R420’s low profile also makes it highly attractive for departmental email, workgroup collaboration, and file and print in space- constrained environments at departmental or remote sites of large businesses and public organizations.
New technologies Table 1 summarizes the newest technologies used in the Dell PowerEdge R420 rack server. Table 1. New technologies New technologies Detailed descriptions Intel Xeon processor This new family of Intel processors has embedded PCIe lanes for improved I/O E5-2400 product family performance.
2 System features Compared to the previous generation of Dell PowerEdge servers, the R420 supports more PCIe slots, PCIe 3.0, more memory, and advanced system management. Table 2 compares some of the features of the R420 to its R410 predecessor. Table 3 lists all of the R420’s specifications.

5 Memory The large memory footprint of the Dell PowerEdge R420 offers greater capacities, higher frequencies, and more flexibility. The R420 supports up to 384GB of memory (12 DIMM slots) and speeds of up to 1600MT/s, providing high performance in a variety of applications. The new reliability, availability, serviceability (RAS) features like memory mirroring and sparing help you increase your uptime and reduce data loss.
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. Dell PowerEdge R420 Systems Owner’s For more information on memory configuration, see the Manual on Support.Dell.com/Manuals.

6 Storage The Dell PowerEdge R420 supports internal and external storage options and controllers, different drive types, and different chassis configurations for a varied number of drives. Features such as CacheCade™ provide accelerated performance over previous technologies. CacheCade uses Dell PERC storage controllers to accelerate performance over hard drives or traditional solid- state drives.
External storage for the R420 is available through optional HBAs for SAS and iSCSI. For more information, see Dell.com/Storage. Storage controllers Dell provides highly capable RAID options for you to ensure that your data remains safe. Dell’s RAID controller options offer impressive performance improvements, including the following features: •...

Figure 7. 550W power supply unit The PowerEdge R420 supports up to two AC PSUs with 1 + 1 redundancy, auto- sensing, and auto- switching capability. The 350W redundant PSU (1 or 1 + 1) is recommended for a one- processor configuration; the 350W PSU in a two- processor configuration may not provide sufficient power, which may impact system performance.
The acoustical design of the PowerEdge R420 reflects the following: • Versatility: The PowerEdge R420 saves you power draw in the data center, but it also is quiet enough for the office environment in typical and minimum configurations. Compare the values for LpA in Table 18 for these configurations, and note that they are lower than ambient measurements of typical office environments.
Idle: Reference ISO 7779 (2010) definition 3.1.7; system is running in its operating system but no other specific activity. Stress: An operating mode per ISO 7779 (2010) definition 3.1.6. The software SPECPower at 50% is activated to stress the processors and DIMM. For more information on Dell’s acoustical design, see the Dell Enterprise Acoustics white paper.
9 Rack rails and cable management The sliding and static rail systems for the Dell PowerEdge R420 provide tool- less 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.
For detailed information about static and sliding rails, see the Rack rail specifications section in Rack Installation Appendix A. For more information on installing the R420 in a rack, see the Instructions on Support.Dell.com/Manuals. PowerEdge R420 Technical Guide...

10 Operating systems and virtualization The Dell PowerEdge R420 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 R420. For the latest information on supported operating systems, see Dell.com/OSsupport.
Supported virtualization One of the key features for virtualization on the PowerEdge R420 is the support for a fail- safe hypervisor. By running a hypervisor on an optional SD card and installing a backup copy on the other mirrored SD card, you can protect against hardware failure and maximize virtualization uptime.
Systems management solutions Dell systems management solutions include a wide variety of tools, products, and services that enable you to leverage an existing systems management framework.
