Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack server built for virtualisation and database workloads. It ships with one Intel Xeon Gold 6126 processor at 2.6 GHz and 256 GB of DDR4 ECC registered memory across sixteen 16 GB modules. The chassis supports up to four 3.5-inch SATA drive bays and includes a PERC H740P RAID controller. A second processor socket is available for future expansion.

Check rack depth power and network

Verify that your rack can accommodate a unit 36 inches deep and that the two 750 W power supplies match your PDU connectors. The integrated 10 GbE 2-port 562T adapter requires compatible switch ports and cabling. Confirm the iDRAC9 Enterprise licence suits your remote-management strategy and that the PERC H740P firmware is current for the drives you plan to install.

iDRAC9 Enterprise and rail kit option

The bundled iDRAC9 Enterprise licence unlocks full remote console, virtual media and automated deployment features without extra cost. A rail kit is available on request to simplify installation in standard racks. The server arrives with BIOS and firmware updated to the latest stable version and has passed full diagnostics and burn-in testing.

Questions about this item

Does the server ship with any 3.5" drives or do I need to purchase SATA drives separately?

The chassis has four 3.5" bays and no drives are installed; you must supply SATA drives yourself.

Should I choose the single Xeon Gold 6126 or add a second processor for my workload?

The board accepts up to two CPUs; the installed Gold 6126 has 12 cores at 2.6GHz, add a second matching processor only if your application scales beyond 12 cores.

What does the 256GB DDR4 figure mean for actual memory bandwidth and capacity headroom?

Sixteen 16GB DDR4 modules fill 16 slots delivering 256GB ECC registered memory; the platform supports up to 7.68TB so substantial expansion headroom remains.
