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.

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 SSDs.

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

Unleash scalable performance

Perform more transactions in less time with the massive memory footprint and tremendous caching capacity of the PowerEdge R920, the most powerful rack server in the PowerEdge portfolio. It introduces to the PowerEdge lineup the next generation of Intel Xeon processor E7 v2 product family, which combines up to 15 cores per processor with a large memory capacity, high-performing threads and hardware-based advanced reliability features designed to:

Process and analyze large amounts of data in real time
Deliver real-time business intelligence
Drive faster decision making
Increase productivity and profitability

Operate confidently

Keep your data center running in top condition with the enhanced reliability features of the PowerEdge R920, including:

Intel Run Sure technology that helps improve system diagnostic and predictive failure analysis to reduce service costs and increase system uptime
Dell Fault Resilient Memory that provides a protected hypervisor memory zone for VMware environments and Dual SD redundant hypervisor for highly available failsafe virtualization
Redundant hot-plug power supply units and fans

System Cooling - Heatsink and Fans

With 4 Processors you'll need Large Heatsinks with plenty of airflow. The Dell R920 has Six hot swappable fans that are mounted in a fan gantry located in the chassis between the hard drive bay and the processors. The fans are placed in the Dimm Riser Cage. Each fan has a blind mate 2x2 connector that plugs directly into the fan tray. An additional fan, integrated in each power supply provides additional cooling for the whole system.

Memory

The R920 supports up to 6TB of LRDIMM memory (with 96 x 64GB LRDIMMs); up to 3TB of LRDIMM memory (with 96 x 32GB LRDIMMs) and up to 1.5TB of RDIMM memory (with 48 x 16GB RDIMMs.)

In addition to supporting registered DIMMs (RDIMM), the R920 supports load reduced DIMMs (LRDIMM), which use a buffer to reduce memory loading and provide greater density, allowing for the maximum platform memory capacity. High memory density provides a richer, no compromise virtualization environment.

Capacity (GB)	Speed (MT/s)	Type	Ranks per DIMM	Data width	SDDC support	Voltage

64	1600	LRDIMM	8	x4	lockstep mode	1.35

PCIe Configurations

Expand IO capabilities

Gain up to 100 percent more IOPS performance than previous-generation PowerEdge servers with the H730P PowerEdge RAID Controller (PERC), a high-performance RAID controller for direct-attached storage (DAS). Taking full advantage of 12Gbps SAS throughput, this PERC enables workload-optimized performance, with RAID6 and RAID60 as standard features. Agentless management through iDRAC7 enables PERC configuration, deployment, updating and monitoring through a simple GUI or command line interface.

With 32 PCIe lanes available from each E7 v2 processor in the system, the R920 provides greatly expanded PCIe slot capability over previous‐generation PowerEdge servers. Dell designed the R920 to be PCIe‐3.0 compliant to take full advantage of the processor capabilities.

Networking Solutions

The PowerEdge R920 offers rack network daughter card (RNDC) options which provide a custom solution that contains a complete network interface controller (NIC) subsystem. The R920 supports one RNDC card instead of the traditional LAN on motherboard (LOM) design. RNDC offer the features and benefits of a traditional LOM subsystem (including NC‐SI management interface) but with expanded features and added flexibility as RNDCs provide an easy upgrade path from 1GB to 10GB LAN speeds.

Storage Controllers

The R920 supports the new PERC 8 family of controllers with improved functionality and faster performance.

The R920 optionally supports a dual-PERC configuration, which enables more flexible PERC usage, for example, dedicating the highest IO requirements to one PERC that leverages higher-performance SSDs while the other PERC can control lower-priority workloads using the HDD storage.
