Maximize application performance and density
The scalable business architecture of the R640 is designed to maximize application performance and provide the flexibility
to optimize configurations based on the application and use case. With the R640 you can create an NVMe cache pool and
use either 2.5” or 3.5” drives for data storage. Combined with up to 24 DIMM’s, 12 of which can be PMems or NVDIMMs,
you have the resources to maximize application performance with the optimum configuration in only a 1U chassis.
• Simplify deployments and speed deployments with Dell EMC ready nodes for VSAN.
• Maximize storage performance with up to 10 NVMe drives or 12 2.5” drives.
• Scale compute resources with 2nd Generation Intel® Xeon® Scalable processors and tailor performance.
Automate maintenance with Dell EMC OpenManage
The Dell EMC OpenManage™ portfolio helps deliver peak efficiency for PowerEdge servers, delivering intelligent, automated management of routine tasks. Combined with unique agent-free management capabilities, the R640 is simply managed, freeing up time for high profile projects.
• Simplify management with the OpenManage Enterprise™ console, with customized reporting and automatic discovery.
• Take advantage of QuickSync 2 capabilities and gain access to your servers easily through your phone or tablet
Guard your data center with built in security
Every PowerEdge server is designed as part of a cyber resilient architecture, integrating security into the full server life
cycle. The R640 leverages new security features built-into every new PowerEdge server strengthening protection so you
can reliably and securely deliver accurate data to your customers no matter where they are. By considering each aspect
of system security, from design to retirement, Dell EMC ensures trust and delivers a worry-free, secure infrastructure
without compromise.
• Rely on a secure component supply chain to ensure protection from factory
to the data center.
• Maintain data safety with cryptographically signed firmware packages
and Secure Boot.
• Protect your server from malicious malware with iDRAC9 Server Lockdown
mode (requires Enterprise or Datacenter license).
• Wipe all data from storage media including hard drives, SSDs.
