1U Rack Server with 4 LFF Bays

The Dell PowerEdge R640 is a 1U rack-mount server built for dense storage workloads. It ships with four 3.5-inch drive bays and a single Xeon Gold 5218R processor running at 2.1 GHz with 20 cores. The system includes 64 GB of DDR4 ECC registered memory and supports up to 7.68 TB total capacity. Buyers who need more than two processors or GPU acceleration should look elsewhere.

PERC H740P RAID Controller Included

The integrated PERC H740P controller manages the SATA drives installed in the four large-form-factor bays. It provides hardware RAID levels for data protection and performance without consuming a PCIe slot. An Ethernet 10Gb 2-port 562T adapter is also fitted for high-speed network connectivity. No drives are included so storage capacity and redundancy must be specified at purchase.

iDRAC9 Enterprise Remote Management

Dell iDRAC9 with Enterprise licence allows full out-of-band control over a dedicated network port. Firmware and BIOS are updated to the latest stable release before shipment and a full burn-in test is completed. The unit uses two 750 W power supplies for redundancy. Rail kits are available on request but not supplied by default.

Questions about this item

How do I add more DDR4 memory to the R640 later?

The server has 64GB installed and supports up to 7.68TB of DDR4 across its DIMM slots, so additional registered ECC modules can be added as workloads grow.

What limits sustained compute on the single Xeon Gold 5218R?

With one 20-core 2.1 GHz processor installed, the primary ceiling under continuous load is the single-socket configuration; a second CPU can be added to double thread count.

How loud and hot does the R640 run with dual 750W supplies all day?

Dual 750W power supplies and the 4LFF chassis fans are designed for 24/7 operation; iDRAC9 Enterprise provides real-time thermal and power monitoring to manage noise and heat.
