7 PowerEdge R720 and R720xd Technical Guide
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.
Intel Xeon processor
E5-2600 product family
This new family of Intel processors has embedded PCIe lanes for improved I/O
performance. See the Processors section for details.
Intel C600 series chipset
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.
Next generation PERC
options
The R720 and R720xd support new PERC controller cards with improved
functionality and faster performance. See the Storage section for details.
PERC S110 software
RAID solution
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.
iDRAC7 with Lifecycle
Controller
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.
Advanced power
management
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 will be 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
®
ESXi™.
Dell has tested and validated an integrated data center solution that enables you to
operate at higher temperatures or even chiller-less. See the Power, thermal, and
acoustics section for details.
