1Product Comparison
1.1 Overview of PowerEdge R910 Benefits
The Dell™ PowerEdge™ R910 provides performance and reliability in a scalable 4U, four-socket server
allowing large workload consolidation or max virtualization machine density.
With Intel® Advanced RAS (Reliability, Availability, Serviceability) Technology, internal dual SD
modules for hypervisor redundancy, including design and component quality paired with Dell
Lifecycle Controller, technicians avoid having to load diagnostics from other media. Dell built-in
reliability saves valuable time and minimizes downtime for mission-critical workloads.
Purpose Built for Reliability
The PowerEdge R910 is built for reliability through factory integration and validation. The Dell ―one-
touch‖ process is designed to ensure one person is responsible for the entire server build, resulting in
greater quality control. Every fully configured Dell server is tested (and re-tested) before it leaves
the factory providing customers a fully configured and tested ready-to-deploy server.
Internal Dual SD module provides failover at the hypervisor; this feature was designed based on
customer reliability feedback. Dell listened and delivered.
With Intel Advanced RAS Technology features never before seen in an industry-standard server, the
PowerEdge R910 can automatically monitor, report, and recover from hardware errors to maintain
data integrity and keep mission-critical services online.
Efficient Infrastructure
Performance resources, power efficiency, I/O, and memory scalability are essential to maximizing
workload in the data center.
The PowerEdge R910 delivers the highest performing Xeon 7500 Series processors, up to 1TB of DDR3
memory, and 2 x 10Gb Optional LOM with 10 PCIe slots to help consolidate inefficient workloads.
Energy-efficient system design built with Energy Smart technologies includes power management
features enabling power capping, power inventory, and power budgeting within your specific
environment. Logical component layout of the internal components aids with airflow direction,
helping to keep the server cool.
Intelligent Platforms, Connected Foundations
The PowerEdge R910 follows the 11th Generation PowerEdge behavioral specifications with the same
system design commonality and usability true to the entire portfolio. All 11th Generation servers are
designed to make the user experience easier while saving time and money.
Dell system management solutions focus on simplicity, efficiency, cost containment and reduction,
and an adherence to open standards. Our systems management solutions are complemented by,
connected to, and integrated with 3rd-party offerings, thereby delivering comprehensive solutions
across the complete solutions stack.
The Lifecycle Controller is a chip that is integrated on the server. It helps to simplify administrator
tasks by performing a complete set of provisioning functions such as system deployment, system
updates, hardware configuration, and diagnostics in a pre-OS environment—all from a single,
intuitive interface called the Unified Server Configurator (USC).
The PowerEdge R910 is easy to deploy, better to manage and maintain. Designed to save customers
time and money to focus on what matters most, their people and business.

1.2 Comparison of PowerEdge R910 to PowerEdge R900
The Dell™ PowerEdge™R910 is Dell’s 11th generation general purpose 4-socket 4U Intel®based rack
server. The R910 features the highest level performance scalability, system availability, and I/O
expandability, providing performance and capacity leadership with reliability built-in to run business-
critical applications. R900 is the predecessor of R910.
The PowerEdge R910 and the rest of the 11th generation servers are designed around optimizing
virtualization, system management, usability and industrial design, and best-in-class power and
thermals. The PowerEdge R910 is ideal for large database, virtualization, and business-critical
applications.
