Dell PowerEdge R640 4LFF Server
This Dell PowerEdge R640 rack server ships with two Intel Xeon Silver 4116 processors running at 2.1 GHz and 512 GB of DDR4 ECC registered memory. The 4LFF chassis supports up to four 3.5-inch SATA drives through a PERC H740P RAID controller. Remote management is handled by iDRAC9 Enterprise and a 10 GbE 562T dual-port adapter is installed.
Suits dense virtualisation and database hosts
The twin 12-core CPUs and half-terabyte of RAM fit workloads that need high core counts and large memory footprints in a 1U form factor. Buyers who need GPU acceleration or more than four drive bays should look at a different chassis. The integrated graphics and lack of installed storage also rule it out for graphics-heavy or boot-from-local-disk deployments.
512 GB DDR4 ECC registered memory
This capacity is the decisive spec: it determines how many virtual machines, containers or in-memory databases the box can run before you must add modules. The system accepts up to 7.68 TB across 24 slots, so the installed 512 GB is a starting point rather than a ceiling.

Questions about this item
Should I pick the 4LFF chassis or a 2.5-inch bay version for my storage needs?
The 4LFF chassis provides four 3.5-inch bays suited for high-capacity SATA drives; choose it when you need maximum raw capacity per bay rather than drive count.
How does the 2.1 GHz clock on the dual Xeon Silver 4116 CPUs translate to real-world throughput?
Each Silver 4116 runs at 2.1 GHz with 12 cores and 16.5 MB cache, so the pair delivers 24 cores total for parallel workloads such as virtualisation or database tasks.
What does the PERC H740P controller cap in practice for SATA drive performance?
The PERC H740P handles RAID across the four 3.5-inch SATA bays, letting you configure redundancy or striping up to the controller's 12 Gb/s per port limit.
