Dell PowerEdge R640 4LFF dual Xeon server

The Dell PowerEdge R640 4LFF chassis holds two Intel Xeon Gold 5218R processors running at 2.1 GHz with 20 cores each and 27.5 MB cache. It ships with 384 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The unit is designed for rack-mount deployments that need high core density and large memory capacity in a 1U form factor.

Tool-less rail installation with optional kit

The server slides into a standard rack using an optional rail kit that can be requested at purchase. Drive bays accept up to four 3.5-inch SATA drives that insert from the front without tools. The PERC H740P controller must be configured in the BIOS before the operating system sees any volumes, and the iDRAC9 Enterprise licence should be activated early for remote firmware updates.

Dual 750 W supplies sustain full load

Two 750 W power supplies share the load and keep the system running if one unit fails. Under sustained compute workloads the dual 20-core CPUs and 384 GB of DDR4 draw continuous power that the redundant supplies handle without throttling. Integrated graphics and the 10 GbE 562T adapter add minimal extra heat, so fan speeds remain stable during long runs.

Preguntas sobre este artículo

How do I verify the R640 boots and shows both Xeon Gold 5218R CPUs and 384GB DDR4 after installation?

Power on the server, open the iDRAC9 Enterprise interface, and confirm the System Overview lists two 2.1 GHz processors and 384GB memory with no errors.

What components are included and which drive parts must be purchased separately for the 4LFF chassis?

The unit ships with two Xeon Gold 5218R processors, 384GB DDR4 ECC Registered memory, PERC H740P RAID controller, 10GbE 562T dual-port adapter, two 750W power supplies, and rails on request; no 3.5" drives are installed.

Which memory capacity should I choose if I need room to grow beyond the installed 384GB DDR4?

The R640 supports up to 7.68TB of DDR4, so the current 384GB leaves ample headroom for future expansion by adding compatible registered ECC modules.
