Dell PowerEdge R640 4LFF Server
This 1U rack server delivers a single Intel Xeon Gold 6226 processor running at 2.7GHz with twelve cores and 19.25MB cache. It ships with 256GB of DDR4 ECC registered memory installed across sixteen DIMM slots and a Dell PERC H740P RAID controller. The 4LFF chassis supports up to four 3.5-inch SATA drives, though no drives are included in this configuration.
Suited For Virtualisation And Database Workloads
The 256GB memory capacity and dual-processor capability make this platform appropriate for memory-intensive virtualisation hosts, mid-size database servers or compute clusters needing room to grow. Remote management is handled by iDRAC9 Enterprise with a 10GbE two-port 562T adapter already fitted. Buyers who require more than four drive bays, discrete GPU compute or a second processor installed from the factory should evaluate larger chassis options.
Maximum Memory Capacity Of 7.68TB Decides Fit
With sixteen DIMM slots and support for up to 7.68TB of DDR4, the ceiling for memory expansion is the single specification that determines whether this R640 can accommodate future growth. The installed 256GB uses 16GB modules, leaving headroom for higher-density sticks when workloads demand it. Power is supplied by two 750W units and the system measures 36 by 24 by 10 inches weighing 40 pounds.

Questions about this item
How many 3.5 inch drive bays does the R640 chassis provide?
The chassis supports up to four 3.5 inch drive bays for SATA storage.
What is the correct sequence for installing the second processor and matching memory?
Install the second Xeon 6226 in socket two, then populate its twelve dedicated DDR4 slots to balance the 256GB across both CPUs.
When should the PERC H740P RAID controller battery be checked or replaced?
The controller uses a battery-backed cache; plan to inspect or replace the battery module after three to five years of continuous operation.
