Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 5118 processors running at 2.3 GHz with 12 cores each. It ships with 64 GB of DDR4 registered ECC memory across four 16 GB modules and a PERC H730P controller with 2 GB cache supporting RAID 0, 1, 5, 6, 10, 50 and 60. Two 400 GB SATA SSDs are installed in the eight 2.5-inch drive bays.

Suits dense virtualisation; not for GPU workloads

This configuration suits organisations deploying virtualisation clusters, database nodes or high-performance computing tasks that benefit from 24 cores and hardware RAID in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links, and iDRAC9 Enterprise enables full remote management. Buyers needing GPU acceleration or more than eight drive bays should evaluate alternative platforms.

Verify rack depth and network cabling

Confirm the rack can accommodate the server depth and that the included sliding rails fit the mounting posts. Ensure SFP+ transceivers and fibre or direct-attach cables match the 10 Gb ports on the X520/I350 card. Check that the two 750 W platinum power supplies connect to separate PDU circuits for redundancy. Memory expansion uses the remaining 20 DDR4 slots up to a 3 TB maximum.

Questions about this item

What memory type and speed must the 24 DIMM slots be populated with to reach the 3 TB maximum on this R640?

The 24 slots accept DDR4 registered ECC modules at 2400 MHz; the server ships with 64 GB in four 16 GB sticks and supports up to 3 TB total.

How do the dual Xeon Gold 5118 CPUs and the H730P controller share the 2.5-inch drive bays with existing SATA SSDs?

The H730P manages all eight 2.5-inch bays over 12 Gb/s SAS/SATA; the two installed 400 GB SATA SSDs occupy two bays and the remaining six bays are open for additional SAS or SATA drives.

How can I verify the iDRAC9 Enterprise remote management is active after the server boots?

During POST the iDRAC9 firmware version appears on screen, and a dedicated management network port lights up; you can then log in via its IP address to confirm the Enterprise licence is enabled.
