1U rack server for virtualization workloads

The Dell EMC PowerEdge R640 is a 1U rack server built for business workloads such as virtualization, databases and application hosting. Two Intel Xeon Gold 6136 processors deliver 24 cores at 3.0 GHz with Turbo Boost up to 3.70 GHz. 64 GB of DDR4 ECC registered memory supports multiple services and virtual machines.

Suited for density-constrained racks needing 12

This configuration fits buyers who need high core density and 12 Gb/s SAS storage in a single rack unit. The eight 1.2 TB 10K SAS drives and H740P controller provide capacity for operating systems, applications and backups. It is not for buyers who require GPU compute acceleration or more than two processor sockets.

H740P RAID controller with 8 GB cache

The integrated Dell Perc H740P controller with 8 GB cache manages the eight SAS drives and simplifies storage setup and day-to-day management. This specification determines whether the server matches storage performance and RAID requirements.
