Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out deployments. It ships with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Dual 750 W platinum redundant power supplies, iDRAC9 Enterprise, rails and a front bezel are included.

Compute Density Focus

This configuration suits workloads that demand high core counts and fast local storage in a single rack unit. The eight 400 GB SATA SSDs and PERC H730P controller with 2 GB cache support RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need more than 24 DIMM slots, additional drive bays beyond the eight 2.5-inch bays, or more than two processor sockets should evaluate other platforms.

DDR4 2666 MHz Memory Standard

The installed 256 GB uses DDR4 2666 MHz registered ECC modules; the platform accepts up to 3 TB across 24 slots. Only DDR4 memory is compatible — other DDR generations will not fit. Matching this memory type is the single specification that determines whether additional modules can be used.

Questions about this item

Do I need to supply my own SFP+ transceivers for the 10 GbE ports on the X520/I350 network daughter card?

The X520/I350 card provides two 10 Gb SFP+ ports; transceivers and cables are not included and must be sourced separately.

Can the PERC H730P controller manage both the installed 400 GB SATA SSDs and additional 12 Gb/s SAS drives I might add later?

Yes, the H730P supports SAS and SATA simultaneously across its eight 2.5-inch bays, allowing mixed SSD and HDD configurations.

How do I confirm the iDRAC9 Enterprise remote management is active after the server powers on?

Connect the dedicated iDRAC network port, browse to its IP address, and the Enterprise licence will be shown on the login dashboard.
