Table 1 summarizes the newest technologies used in the Dell PowerEdge R520 rack server.New technologies Detailed descriptionsIntel Xeon processorE5-2400 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 Intel Platform Controller Hub (PCH) chip is implemented on the R520 server.1600 MT/s DDR3memoryCertain models of the E5-2400 series processors support 1600 MT/s memory. TheR520 supports two DIMMs per channel at 1600 MT/s with certain models. See theMemory section for details.Next generation PERCoptionsThe R520 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, and supports amaximum of four hot-plug SATA hard drives or SATA solid-state drives. See theStorage 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.DC power supply A new 1100W DC power supply option is available for the R520. See the Power,thermal, and acoustics section for details.Advanced powermanagementThe R520 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 is a modular fail-safe design that is dedicated for anembedded ESX hypervisor or other embedded operating system. See theSupported virtualization section.Fan fault toleranceFailure of one fan motor is tolerated with degradation in performance throughactive throttling and increased fan speeds. The feature helps reduce downtime byallowing you to schedule a fan replacement within 360 hours of a fan failure.
