Rack server with dual Silver 4108 CPUs

The Dell PowerEdge R640 is a 1U rack-mount server equipped with two Intel Xeon Silver 4108 processors running at 1.8 GHz. It ships with 384 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The chassis provides four 3.5-inch drive bays for SATA storage. Remote management is handled by iDRAC9 with an Enterprise licence.

384 GB DDR4 ECC registered memory

The installed memory capacity of 384 GB across DDR4 ECC registered modules determines whether this server fits workloads that demand large in-memory datasets. The platform supports a maximum of 7.68 TB, allowing future expansion if the current configuration proves insufficient. No storage drives are included, so the buyer must supply SATA drives for the four available bays.

Dual 750 W power supplies and 10 GbE networking

Two 750 W power supplies deliver redundancy for continuous operation in a 36 by 24 by 10 inch rack footprint weighing 40 units. An integrated 10 GbE two-port 562T adapter provides high-throughput network connectivity. The unit has undergone full diagnostics, burn-in testing and firmware updates before shipment.

Questions about this item

What does the 384GB DDR4 ECC memory mean for real-world virtualization density?

With 384GB of DDR4 ECC registered memory installed, the system can host dozens of virtual machines simultaneously while protecting data integrity through error correction.

How does the PERC H740P controller with SATA interface affect storage performance?

The PERC H740P RAID controller manages up to four 3.5-inch SATA drives, providing hardware RAID acceleration but capping throughput at the SATA bus limit.

What physical space and power does the 36 x 24 x 10 inch, 40-pound chassis require?

The 1U rack-mount chassis measures 36 by 24 by 10 inches, weighs 40 pounds, and draws power from two 750W supplies, so plan rack depth and PDU capacity accordingly.
