Dell PowerEdge R640 4LFF Server Configuration

This Dell PowerEdge R640 rack server arrives new with two Intel Xeon Gold 6246R processors running at 3.4 GHz and 256 GB of DDR4 ECC registered memory. The 4LFF chassis supports up to four 3.5-inch SATA drive bays and includes a PERC H740P RAID controller. Remote management is handled by iDRAC9 with an Enterprise license. Dual 750 W power supplies provide redundancy.

Suitable For Virtualisation And Database Workloads

The dual 16-core CPUs and large memory capacity suit virtualisation hosts, database servers and compute-intensive applications that benefit from high core counts and ECC memory. Buyers who need GPU acceleration or more than four internal drive bays should evaluate other platforms. The integrated graphics and 10 GbE 562T adapter cover basic display and networking needs without extra cards.

256 GB DDR4 ECC Registered Memory Installed

The system ships with 256 GB of DDR4 ECC registered memory installed across the available DIMM slots. Maximum supported capacity reaches 7.68 TB when fully populated with compatible modules. Memory type and speed must match DDR4 ECC registered specifications for stable operation.

Questions about this item

How do I verify the PERC H740P RAID controller is recognised after the server boots?

Enter the controller BIOS with Ctrl+R during POST and confirm the H740P firmware version is displayed; the server also logs the controller status to iDRAC9 Enterprise for remote viewing.

The listing says no drive is installed — which drive caddies and cables must I source separately for the four 3.5-inch bays?

The 4LFF chassis includes the backplane and four hot-plug caddies; you only need to supply 3.5-inch SATA hard drives or SSDs.

Should I choose the 256 GB DDR4 configuration or add modules up to the 7.68 TB maximum for virtualisation workloads?

Start with the installed 256 GB DDR4 ECC Registered; the 24 DIMM slots allow simple expansion later without replacing existing modules.
