DELL PowerEdge R640 4LFF 2x Xeon Silver 4216 64GB DDR4 No Drive

Dual Xeon Silver 4216 server for dense compute

The Dell PowerEdge R640 fits two Intel Xeon Silver 4216 processors, each running at 2.1GHz with sixteen cores and 22MB cache. Sixty-four gigabytes of DDR4 ECC registered memory are installed across the board. The 4LFF chassis accepts up to four 3.5-inch SATA drives, though none are included in this configuration. Integrated graphics handle basic display output while the PERC H740P RAID controller manages storage arrays. Remote administration is provided by iDRAC9 with an Enterprise licence.

7.68TB memory ceiling and four drive bays

Installed memory sits at 64GB, leaving substantial headroom toward the 7.68TB maximum supported by the dual-socket design. The four 3.5-inch bays connect through the PERC H740P controller over SATA, so capacity scales with the drives you add. Compute throughput is fixed by the two 16-core Xeons; workloads that demand more threads or higher single-core frequency will hit that ceiling. The 10GbE 2-port 562T adapter supplies network bandwidth, but storage performance ultimately depends on the drive selection.

Dual 750W supplies and optional rail kit

Two 750W power supplies deliver redundancy for continuous operation in a rack environment. The iDRAC9 Enterprise licence enables full out-of-band management, virtual console and lifecycle automation without extra cost. A rail kit is available on request, so plan for that if your cabinet requires it. Buyers who need drives, additional memory modules or a different drive-count chassis should specify those changes before ordering.
