1U Rack Server for Virtualisation Workloads

The Dell PowerEdge R640 fits a standard 1U rack space and ships with one Xeon Gold 6148 processor running at 2.4 GHz across ten cores. It includes 128 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The chassis provides four 3.5-inch drive bays ready for SATA hard drives or SSDs. This configuration targets businesses that need dense compute for virtualisation, databases or general-purpose applications.

Dual 750 W Supplies and 10 GbE Adapter

Two 750 W power supplies from the R720 line deliver redundant power for continuous operation. A 10 GbE dual-port 562T network adapter is installed, providing high-throughput connectivity for storage replication or cluster traffic. The iDRAC9 Enterprise licence enables full remote management including virtual console and power control. No drives are included, so storage capacity and RAID level are chosen at order time.

Single Processor Limits Maximum Core Count

Only one of the two possible CPU sockets is populated, capping the system at ten cores and 27.5 MB of cache. Memory can scale to 7.68 TB when the second processor is added, but the current 128 GB fills only a fraction of the available slots. Buyers who need more than ten cores or plan to exceed the single-socket memory limit should order the second Xeon Gold 6148 at configuration.

Questions about this item

Will the Xeon Gold 6148 processor need replacement or can a second one be added later?

The server has one Xeon Gold 6148 installed and supports a maximum of two processors, so a second compatible CPU can be added.

What storage limit appears first with four 3.5-inch drive bays and the PERC H740P controller?

The chassis provides four 3.5-inch bays, so the physical bay count is the first limit before the controller capacity is reached.

How much heat and power should I expect from the two 750W supplies running all day?

Dual 750W power supplies provide redundant power; actual draw depends on the drives and second CPU you install.
