Dell PowerEdge External OEMR XL R720XD Technical Guide - Page 7

simplify the lifecycle of deploying, updating, monitoring, and maintaining your Dell PowerEdge servers. New technologies featured on the PowerEdge R720 and R720xd systems are detailed in Table 1. New technologies Detailed descriptions Intel Xeon processor E5-2600 product family Intel C600 series chipset 1600 MT/s DDR3 memory LRDIMM Flexible LOM Next generation PERC options PERC S110 software RAID solution Express Flash drives iDRAC7 with Lifecycle Controller Internal GPU support Advanced power management DC power supply Failsafe hypervisors This new family of Intel processors has embedded PCIe lanes for improved I/O performance. See the Processors section for details. The Intel Platform Controller Hub (PCH) chip is used on the R720 and R720xd. Certain models of E5-2600 series processors support 1600 MT/s memory. The R720 and R720xd support two DIMMs per channel at 1600 MT/s with these processors. See the Memory section for details. This new memory option, load reduced DIMM (LRDIMM), is designed with a buffer chip (or chips) to replace the register to help minimize loading. LRDIMMs can increase overall server system memory capacity and speed. See the Memory section for more information. Dell's Select Network Adapter options allow you to customize your LAN port combinations from your choice of controller vendors. See the Networking and PCIe section for details. The R720 and R720xd support new PERC controller cards with improved functionality and faster performance. See the Storage section for details. This new software RAID solution supports RAID 0, 1, 5 and 10 and supports a maximum of four hot-plug SATA HDDs or SSDs. See the Storage section for details. Dell Express Flash PCIe solid-state drives provide fast performance without requiring processor resources or capturing DRAM. The R720 supports up to four Express Flash drives. The R720xd does not support Express Flash drives. The new embedded system management solution for Dell servers features hardware and firmware inventory and alerting, in-depth memory alerting, faster performance, a dedicated gigabit port and many more features. See the Dell OpenManage systems management section for details. The R720 supports internal graphics processing units (GPUs) for extreme computing power to solve high performance computing (HPC) needs. The R720xd does not support internal GPUs. See the Processors section for details. The R720 and R720xd support advanced power monitoring and power capping tools that can help manage power consumption. A new 1100W DC power supply option is available for the R720 and R720xd. The internal dual SD module enables Dell's unique Failsafe Virtualization architecture, ensuring uptime by providing failover capability for embedded hypervisors, such as VMware® vSphere® ESXi™. 7 PowerEdge R720 and R720xd Technical Guide
