1 System overview

Introduction
Designed to run mission‐critical applications for midsized and large enterprises, the Dell™
PowerEdge™ R920 is a compute‐intensive rack server with highly scalable memory and impressive
I/O capabilities to match. With up to four Intel
support dual RAID controllers and up to 6TB of memory, the PowerEdge R920 can readily handle
the most demanding workloads and is ideal for large databases, Enterprise Resource Planning, e‐
commerce, business decision applications and high‐performance computing. The PowerEdge R920
is also an excellent choice for organizations looking to migrate from an outdated RISC architecture.
Scale to match the challenge
React at the speed of business with the R920's highly scalable memory, I/O options and storage
components. With four Intel Xeon E7 v2 processors, 96 DIMMs, 10 integrated PCI Express® (PCIe)
expansion slots and 24 internal storage drives, the R920 gives you processing power, flexibility and
capacity for growth. Build out your SAN capacity as your business grows. Keep pace with the
increasing data demands of large enterprise applications with H730P PERC, dual PERC capability and
up to eight NVMe Express Flash PCIe
Get results faster
Accelerate the time it takes enterprise applications to deliver services by eliminating the chokepoint
— the speed of access to data. Use the R920's 24 internal storage drives, or take advantage of its 10
PCIe expansion slots to drive large scale SAN storage. With options like high‐performance 12Gbps
SAS drives, dual RAID controller capabilities and Express Flash NVMe devices, you can reduce
storage access times and improve overall application efficiency.
Enterprise‐wide systems management
PowerEdge embedded management technology, integrated Dell Remote Access Controller 7
(iDRAC7) with Lifecycle Controller, helps IT administrators manage Dell servers in physical, virtual,
local and remote environments — agent‐free or in‐band with a systems management software
agent installed. iDRAC7 Enterprise features include a multi‐administrator virtual console, virtual
media and remote file share that enable IT admins to operate servers "as if they were there,"
ensuring secure access to servers from anywhere in the world. OpenManage™ Essentials, a
comprehensive monitoring and management console, available as a no‐charge software download,
simplifies and automates basic hardware management tasks while Dell SupportAssist helps you
maintain a healthy and productive environment.
