Compact rack server for virtualisation and databases

The Dell PowerEdge R640 fits a 1U rack height and holds ten 2.5-inch drive bays, making it suitable for dense deployments that run file storage, virtualisation, databases, backups and application hosting. Two Intel Xeon Gold 6134 processors deliver sixteen cores at 3.20 GHz, and 128 GB of DDR4 memory supports multiple services and virtual machines.

Dual CPU and RAID controller simplify daily

The LGA 3647 socket platform is fully populated with two CPUs, reaching the maximum processor count for this chassis. An integrated H740P RAID controller manages the two installed 1.2 TB SAS hard drives, streamlining storage configuration and ongoing administration without additional hardware.

Air-cooled 1U design handles sustained workloads

Front-to-rear airflow through the compact chassis cools both processors and the drive cage during continuous operation. Power draw scales with the dual 16-core CPUs and memory population, while fan speeds adjust to thermal demand, keeping acoustics appropriate for a server room environment.

Questions about this item

Does the Dell Perc H740P RAID controller limit SAS drive speed to 12 Gb/s per lane?

The H740P controller supports 12 Gb/s SAS lanes, so each 1.2 TB drive can run at the full interface rate; the backplane does not impose a lower ceiling.

What physical space and mounting hardware does the 1U PowerEdge R640 10-bay server require?

The 1U high, 2.5-inch SFF chassis occupies one rack unit and ships with Dell ReadyRails sliding rails for a standard four-post rack.

How is the H740P RAID controller installed, and what step do builders often miss?

The H740P plugs into the dedicated internal storage slot; the step often missed is connecting the two SAS cables from the backplane to the controller ports before closing the lid.
