Ideal balance of density and scalability
Get scalable computing and storage in a 1U, 2-socket platform with an ideal mix of performance, cost and density for most data centers.

Uncompromising performance and density for data center productivity and scale
The PowerEdge R640 is the ideal dual-socket platform for dense scale-out data center computing and storage. Benefit from the flexibility of 2.5” or 3.5” drives, the performance of NVMe and embedded intelligence to ensure optimized application performance in a secure platform. With embedded diagnostics and SupportAssist, the R640 delivers maximum uptime in a worry-free environment.Ideal workloads:
- Dense software-defined storage
- Service providers: application tier
- Dense private cloud
- Virtualization
- HPC

Drive transformation with the Dell PowerEdge portfolio
Data center evolution starts with modern platforms that easily scale and are optimized for application performance. The PowerEdge R640 is built upon a scalable system architecture and provides the choice and flexibility to easily meet performance demands.- Simplify deployment and easily scale from 3 to 1000+ nodes for software-defined storage with Dell Ready Nodes.
- Maximize performance with up to 10 NVMe drives and 24 DIMMs, 12 of which can be DCPMMs or NVDIMMs
- Scale compute resources with 2nd Generation Intel® Xeon® Scalable processors, and tailor performance based on your unique workload requirements.

Automate productivity with intelligent, embedded management
Dell automation and intelligent management mean you spend less time on routine maintenance so you can focus on bigger priorities.- Help maximize uptime and reduce the IT effort to resolve issues by up to 72%* with ProSupport Plus and SupportAssist.
- Leverage existing management consoles with easy integrations for VMware® vSphere®, Microsoft® System Center and Nagios®.
- Improve productivity with agent-free Dell iDRAC9 for automated, efficient management.
- Simplify deployment with OpenManage next-generation console and server profiles to fully configure and prep servers in rapid, scalable fashion.

Fortify your data center with comprehensive protection
Dell provides a comprehensive, cyber-resilient architecture with security embedded into every server to protect your data.- Protect server configuration and firmware from malicious changes with new Configuration Lock-down.
- Use system erase of local storage to help ensure data privacy when you repurpose or retire servers.
- Automate updates that check file dependencies and proper update sequence, before deploying them independently from the OS/hypervisor.
- Take control of your firmware consoles with embedded authentication that is designed to allow only properly designed updates to run.
