v PowerEdge R720 and R720xd Technical Guide

The Dell™ PowerEdge™ R720 and R720xd are Dell’s latest 2-socket, 2U rack servers that are designed to run complex workloads using highly scalable memory, I/O capacity, and flexible network options. Both systems feature the Intel® Xeon® processor E5-2600 product family, up to 24 DIMMS, PCI Express® (PCIe) 3.0 enabled expansion slots, and a choice of NIC technologies.

The PowerEdge R720 is a general-purpose platform with highly expandable memory (up to 768GB) and impressive I/O capabilities to match. The R720 can readily handle very demanding workloads, such as data warehouses, e-commerce, virtual desktop infrastructure (VDI), databases, and high-performance computing (HPC).

In addition to the R720’s capabilities, the R720xd offers extraordinary storage capacity, making it well suited for data-intensive applications that require storage and I/O performance, like medical imaging and email servers.

Keep pace with the explosion of data in the virtual age with the flexible I/O and storage capabilities of the R720 and R720xd. The R720 supports up to sixteen internal hard drives to increase your capacity, while optional hot-plug, front-access Express Flash PCIe solid-state drives (up to four) enable performance-enhancing, in-box storage tiering.

The PowerEdge R720xd allows you to quickly access and process vast amounts of data with up to twenty-six internal hot-plug hard disks. The R720xd is a great solution for any mid-size or large business that requires scalability in storage capacity.

The R720 and R720xd allow you to tailor your network throughput to match your application needs, enabling added I/O performance. Select Network Adapters, Dell’s flexible NIC technology, let you choose the right network fabric without using up a valuable PCI slot. You can pick speed, technology, vendor and other options, like switch independent partitioning that lets you share and manage bandwidth on 10GbE connections.

Maximize your data center’s application capacity by expanding your virtual environment using the large memory footprint of the R720 and R720xd. Choose an industry-leading hypervisor and take advantage of our system management capability to manage both physical and virtual assets. Redundant failsafe hypervisors can also help maximize your virtual machines’ uptime. Dell’s Virtual Integrated System (VIS) solution lets you enable complex virtualization environments in just a few mouse clicks.

The Dell OpenManage™ systems management portfolio includes the Integrated Dell Remote Access Controller 7 (iDRAC7) with Lifecycle Controller. Dell embedded server management features help IT Administrators manage Dell servers in physical, virtual, local and remote environments, operating in-band or out-of-band, with or without a systems management software agent. OpenManage also integrates with and connects to third-party systems management solutions so you can maintain your single point of control and capitalize on your existing investment.

simplify the lifecycle of deploying, updating, monitoring, and maintaining your Dell PowerEdge

New technologies

Detailed descriptions

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.

1600 MT/s DDR3 memory

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.

LRDIMM

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.

Flexible LOM

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.

Express Flash drives

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.

Internal GPU support

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.

DC power supply

A new 1100W DC power supply option is available for the R720 and R720xd.

Failsafe hypervisors

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™.
