Dell PowerEdge R640 4-bay server
The Dell PowerEdge R640 is a 1U rack-mount server built for dense compute workloads. It ships with one Intel Xeon Silver 4208 processor running at 2.1 GHz and 256 GB of DDR4 ECC registered memory across sixteen slots. The chassis provides four 3.5-inch drive bays backed by a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise licence.
Suits single-socket density needs.
This configuration suits environments that need maximum memory per socket in a compact form factor. Virtualisation hosts, database nodes and high-performance computing clusters benefit from the 256 GB DDR4 capacity and 10 GbE connectivity. Buyers who require a second processor from day one, or who need more than four drive bays, should evaluate larger chassis options.
PERC H740P RAID controller defines storage
The installed PERC H740P controller manages the four SATA drive bays and provides hardware RAID acceleration with on-board cache. It determines which RAID levels are available and whether the array can survive a drive failure without performance loss. Confirm that the controller feature set matches your redundancy and throughput requirements before deployment.

Questions about this item
Will the PERC H740P RAID controller need a battery or capacitor replacement over time?
The PERC H740P controller includes a cache backup module that may require replacement after several years of continuous operation.
What limits sustained CPU performance in this single-processor configuration?
The single Xeon Silver 4208 at 2.1GHz with 8 cores and 11MB cache sets the processing ceiling under prolonged workloads.
How much power do the dual 750W supplies draw when the server runs all day?
Two 750W power supplies provide redundancy; actual draw depends on installed drives and workload but stays within the 750W per supply rating.
