6 PowerEdge R820 Technical GuideKey technologiesTable 1 summarizes key technologies used in the Dell PowerEdge R820 rack server.Table 1. Key technologiesNew technologies Detailed descriptionsIntel Xeon processorE5-4600 product familyThis new family of Intel processors has embedded PCIe lanes for improved I/Operformance. See the Processor section for details.Intel C600 series chipset The R820 server uses the Intel Platform Controller Hub (PCH) chip.1600MT/s DDR3memoryCertain models of the Intel Xeon processor E5-4600 product family support1600MT/s memory. The R820 supports four DIMMs per channel at 1600MT/s withthese processors. See the Memory section for details.LRDIMMThis new memory option, load reduced DIMM (LRDIMM), is designed with a bufferchip (or chips) to replace the register to help minimize loading. LRDIMMs canincrease overall server system memory capacity and speed. See the Memorysection for details.Flexible LOMThe Dell Select Network Adapter options allow you to customize your LAN portcombinations from your choice of controller vendors. See the Networking andPCIe section for details.Next-generation PERCoptionsThe R820 supports the new PERC controller cards with improved functionality andfaster performance. See the Storage section for details.PERC S110 softwareRAID SolutionThis new software RAID solution supports RAID 0, 1, 5 and 10; supports maximumof four hot-plug SATA hard drives or SATA SSDs. See the Storage section fordetails.Express Flash drivesDell Express Flash PCIe SSDs provide fast performance without requiringprocessor resources or capturing DRAM. The R820 supports up to four ExpressFlash drives. See the Storage section for details.iDRAC7 with LifecycleControllerThe new embedded system management solution for Dell servers featureshardware and firmware inventory and alerting, in-depth memory alerting, fasterperformance, a dedicated gigabit port and many more features. See the DellOpenManage systems management section for details.Internal GPU support The R820 supports internal graphics processing units (GPUs) for extremecomputing power to solve HPC needs. See the Processor section for details.DC power supply A new 1100W DC power supply option is available for the R820. See the Power,thermal and acoustics section for details.Advanced powermanagementThe R820 supports advanced power monitoring and power capping tools that canhelp manage power consumption. See the Power, thermal and acoustics sectionfor details.Fresh Air coolingDell has tested and validated an integrated data center solution that enables youto operate at higher temperatures or even chiller-less. See the Power, thermal andacoustics section for details.Failsafe hypervisorsThe internal dual SD module enables Dell's unique Failsafe Virtualizationarchitecture, ensuring uptime by providing failover capability for embeddedhypervisors, such as VMware® vSphere® ESXi™.
